HP LoadRunner and its Architecture: An Introduction

Posted on by tbsupadminnxtbackendacc

Did you know companies lose up to $4.4 billion annually because of poor web performance? If your website doesn’t load within eight seconds, the users are going to switch to another one.
This is where performance testing comes into the picture. Currently, around 500 people might be using your software, but how will it behave with 50,000 users? By performance, we mean that the software should be scalable, load pages at faster speed, and stay stable despite rapid increase in visitors.
There are different types of tests to check the different variables including peak test, endurance test, stress test, and load test.
In this article, we are going to talk about HP LoadRunner, which is often considered as a pioneer in the field of performance testing.

What is HP LoadRunner?

An efficient performance testing tool, LoadRunner was first developed by Mercury in 1999. It was acquired by HPE in 2006, who then sold it to MicroFocus in 2016.

The tool is so popular that it owns 85 percent of the performance testing market share. It supports Rich Internet Applications (RIA), MS SQLServer, Web 2.0 (HTTP/HTML, Flex, Ajax, and Silverlight among others), Mobile, RTE, Mail, and other technologies, putting HP LoadRunner at a top position above all competitors.
Over the years, clients have considered HP LoadRunner as a benchmark for judging their product’s performance.
You can use it along with Application Lifecycle Management (ALM) and Unified Functional Test (QTP) as all three together act as an end-to-end solution for your product’s testing phase.
The tool simulates Virtual Users on your website or web application and replicates user requests and application responses to give you an in-depth look into how it will behave in a real situation.

Let’s take a look at six amazing features offered by its latest version, LoadRunner 12.60:

  • You can enable or disable HTTP/2 features using the runtime setting
  • The Network Virtualization feature is now free to use
  • You can connect one or multiple IP addresses for Oracle NCA protocol using the updated runtime setting
  • It offers new and updated Dockerized Load Generators
  • It offers better desktop pool support that you can use to sync on bitmap timeout per step for PCoIP protocol
  • You can now save a graph as an image file

HP LoadRunner Architecture

The LoadRunner architecture can get a bit complex, so let’s take one step at a time:
It has five key components, which include:

  • Load Generator
  • Controller
  • Vu Gen
  • Agent process
  • Analysis

Apart from this, it also offers modules to replay, capture, and script multiple application and networking technologies, which include:

  • Applications that use .NET and Java
  • Database servers including Oracle and Microsoft SQL Server
  • Remote client technologies like RDP and Citrix ICA
  • Internetworking protocols like LDAP, DNS, and FTP
  • E-mail protocols such as IMAP, POP3, MAPI, and SMTP

Let’s use an example to understand how the architecture works. Suppose you are checking the performance of your website, abcxyz.com for 5,000 visitors. They won’t be on the home page at once but different parts of the website. Each component plays specific roles in the performance testing process.

1. Load Generator

It simulates the VUsers (virtual users), which take up the hardware resources including processor and memory.
You will have to use multiple load generators so that the results are accurate, which depends on the number of VUsers.
The machines use 2 to 4 MB data to develop one simulated VUser, so you will need multiple machines that have a total of 1.25 GB of RAM space.

2. Controller

The controller is the most crucial component of the architecture as it manages the load simulation. Some other functions that it performs include:

  • IP spoofing
  • Error reporting
  • Nature of Load scenario
  • Handling VUsers behavior

Let’s say, 250 simulated users are in checkout, 3,000 are checking products on your website, and the remaining are making the payment. To keep the load real, the controller will release five customers every two seconds. They will be divided into two machines equally.

3. Vu Gen

Virtual User Generator replicates System under Load and records behavior and communication of the VUsers to and fro with the server in a scripted format. Examples of the business communication it records include:

  • Payment Processing
  • Product Surfing
  • Checkout
  • Checking User Profile

4. Agent process

It controls the way Controller and Load Generator communicates with each other.

5. Analysis

It records user logs from multiple load generators in the required formats. It also monitors data and helps you run result data.

How to plan performance testing?

You can divide HP LoadRunner Performance Testing process into five steps, which include:
1. Load Test planning – In the first step, you define the goals, select the system you want to use, and gather system usage data.
2. Creating VUGen Scripts – The actual process begins as you start recording VU Scripts, add test data, and enhance scripts.
3. Scenario Creation – You create scenarios that help you create a simulated reality. You will have to realign the goals to achieve accurate results.
4. Scenario Execution – In this step, you have to perform overload testing after executing the scenario.
5. Results Analysis – You have to check how the expected results with the actual results. Collect the feedback and make changes to your website.
The next process that follows performance testing is tweaking and optimization of your website or web application.

During this, you have to optimize the code, fine tune the system, and change configurations to make the website efficient enough to handle more visitors. After making the changes, you can run the HP LoadRunner test once more.

The Cruciality of Statistical Testing

Posted on by tbsupadminnxtbackendacc

Most software testing techniques are aimed towards finding errors and defects in software or program which hamper its functioning or cause security breaches.

However, checking a system for errors is not enough; we also need to test the system for its reliability.

However, checking a system for errors is not enough; we also need to test the system for its reliability.

In order to deliver the most reliable software it is important to understand what causes errors and system failures, how frequently do errors interrupt the system, what is the program failure rate, which paths to test while performing software testing and analyzing the failures is very important.

Statistical testing is one such testing which covers all the above requirements. It helps you build and deliver reliable and robust software which work efficiently.

What is Statistical Testing?

Statistical Testing is a testing technique which is used to determine the reliability of the system. In statistical testing, we use statistical models and functions to monitor and check the overall working of the system.

The aim of statistical testing is not to find defects, but to understand how the faults in a program will affect the functioning and operations of the software.

In Statistical testing, statistical models are used to generate test data and test cases which stimulate a working environment. Operations and research models are used to solve any problems detected during the software testing process.

During statistical testing, empirical data is collected which helps testers take efficient decisions for further testing, deployment, maintenance and evolution of the software system. The statistical principles and methods are applied to software testing process with the help of the operational usage model.

What is the need for Statistical Testing?

Software testing is a lengthy process which includes the documentation and use of heavy numerical and statistical values. These values help in decision making for future testing cycles and also are seen as the results of the testing process.

However, software testing is a very complicated process and the complex statistical values are hard to handle and understand. Some issues faced during software testing are:

  1. There is a high cost involved in achieving 100% path coverage when the defects found are of complex nature and quality.
  2. The defects found by software testing need to be reworked and integrated into the system during the development life cycle.
  3. Without proper knowledge about statistical formulas and methods, the tester cannot conduct a bias free software test.
  4. Statistical functions are required to deduce an accurate solution and make efficient decisions during testing. 

For this reason, statistical principles are used to facilitate and guide the testing process and generate better results.

The Statistical Testing process

The Statistical Testing process consists of the following steps:

  1. Operational usage modeling
  2. Analysis of the model and Validation
  3. Test planning
  4. Testing

Operational Usage Model

During Statistical testing, a model is needed in order to characterize and infer the population of uses of the software system. The model is used to generate a statistically accurate sample of the uses if the software.

The Usage model is one such model which characterizes the population of the possible uses in the intended environment. It does not depend on the program code but is based on the software specifications. Thus, it ensures that frequently occurring failures and bugs get detected in the early stages of software testing.

No extra time is required to develop this model as it can be created parallel to the software. This reduces the time required in completing and delivering the software.

The model is also known to improve the specifications, provides a scientific reasoning and analytical description of the specifications, quantifies testing costs, and provides bases for statistical testing which improves the system reliability.

Thus, statistical testing which is based on this model provides strong scientific foundation for quantifying the software reliability.

Usage Model generates multiple execution paths and all possible use cases for the software. It can be seen as a graph containing nodes and arcs and transition probabilities which are associated with each arc.

During operational usage modeling the following process is followed:

  1. Building Model Structure
  2. Assigning Transition Probabilities
  3. Generating Transition Probabilities

Step 1: You need to identify the hardware, software and human users of the software, the stimuli that these users can send, and the system boundary.

Step 2: Create a structure of the usage model by sequencing the stimuli. You need to identify the areas which can become complex and increase the cost of system development. Provide solutions and alternatives to simplify these complexities.

Step 3: Determine the number of environments to be modeled for the system and also define the environments of use which are important, e.g., malicious use, routine use, maximum capacity use, etc.

Step 4: Create transition probabilities of the usage model.

Model Analysis and Validation

A standard set of statistics exists for the usage models which have significant interpretations for safety analysis, test planning, resource allocation, and field support.

The most commonly calculated statistics include:

  • Long-run occupancy of each state
  • Occurrence probability
  • Occurrence frequency
  • First occurrence
  • Expected sequence length

During the model validation process the analytical results are studied and you may find that the system functionalities which you deemed as unimportant have significant usage and those which you thought to be important may have little to no use.

Step 1: First you need to develop standard analytical results for the model. The analytical values need to be interpreted in terms of the specifications and expected usage in order to validate their accuracy.

Step 2: if values or model structure do not suit the requirements and specifications, you can change them accordingly.

Step 3: After changing the model and incorporating changes you need to repeat the first and second steps.

Step 4: Now, create test cases and check if they are realistic. If the test cases do not look realistic you need to repeat step 2.

Step 5: Use the model to facilitate activities such as performance planning, test planning, safety analysis, and correctness verification.

Test Planning

There are two types of test cases: Random test cases and Crafted/ Non-random test cases.

Non-random test cases remove uncertainties about the functioning of the system and provide control over the overall testing process whether random or crafted.

These are the non-random test cases which should be performed before random ones:

  • Model Coverage Tests
  • Mandatory Tests
  • Regression Tests
  • Critical but unlikely use
  • Importance Tests
  • Partition Test

Step 1: Generate the number of random test cases by using the expected test case length derived during model analysis.

Step 2: Determine the best case scenario where there are no failures during random testing. Also determine the values of product quality and process sufficiency that can be achieved by running the number of test cases generated in Step 1.

Step 3: Determine the worst case scenario by assuming that failures occur constantly and create a log of the failures.

Step 4: Study and analyze the coverage of the model stats, paths, and arcs.

Testing

After the test cases are planned, you can proceed to the testing part.

Step 1: Record the specifications and constants for each version of the software that is tested for reference.

Step 2: Apply these conditions and sustain them in the environment throughout the test.

Step 3: Execute test cases in the order that they were generated.

Step 4: Communication is the key during statistical testing. You need to communicate and discuss matters that affect test decisions with the testing team regularly.

Step 5: Record the failures and bugs that are encountered.

Step 6: You should maintain the testing chain for the current version as well as the history of testing across all the previous versions. The current testing chain will be used for certification and the historical testing chain will be used to study the development and testing process.

Step 7: If you encounter more than one error in the current version you need to take a decision of whether to discontinue testing or not. This decision depends on various factors like the nature of the failures, organizational policies, and schedules.

Guide your stopping decisions based on reliability, confidence, and convergence.

Step 8: If there are no failures during current testing you can base your stopping decision on the reliability, confidence, and convergence measures together with remaining schedules and budgets.

Advantages of Statistical testing

  1. It allows testers to focus on testing the parts of the software which have significant usage.
  2. It allows you to develop more reliable systems.
  3. The estimation of reliability using statistical testing is more accurate than of other methods.

Disadvantages of Statistical Testing

  1. Performing and implementing statistical testing properly is not easy.
  2. Defining operation profiles is complex and there is no way to repeat the process.
  3. Developing statistically significant test cases in statistical testing is very hard.

Conclusion

Statistical testing is not aimed to find defects and faults; its main aim is to increase the reliability of software.

It helps testers take informed and accurate decisions during the software testing process. This is the reason why statistical testing is important in today’s world if you want to deliver reliable and robust software applications.

What is Exploratory Testing in Software Testing?

Posted on by tbsupadminnxtbackendacc

Exploratory testing is a process where testers can be creative in exploring the software without knowing much about the working of the system. let’s dig deep

What is Exploratory Testing?

It is a testing approach where you explore the system and venture into those aspects and functionalities which may or may not directly affect the system’s outputs, in order to find underlying errors.

It is all about exploring the system, discovering hidden errors, investigating their cause, and rectifying them. There are no pre-defined test cases formed in exploratory testing and therefore the testers explore the system aimlessly in hopes to find unforeseen bugs.

Exploratory Testing

The purpose of performing exploratory tests is to learn more about the system and its functionality and using your existing knowledge about the system to find errors.

Testers need to be very creative and innovative in order to perform exploratory testing as the aim is to test the system for unexpected errors using unexpected techniques.

Even though there are no pre-defined test cases, testers may note down or document their ideas and things they want to test before performing the test.

Description of exploratory testing techniques?

There are different ways the process can be done. Based on that it can be divided into 3 main types as below:

  1. Freestyle Testing: As the name suggests, this is ad-hoc testing where-in each tester picks up a module or the entire application and randomly runs through the application. It is like a quick smoke test done to ensure everything is as expected.
  2. Scenario-based testing: In this type of exploratory testing, each tester picks up a user scenario and tests the application flows around that use case. They try to cover as many navigations, data permutations, and flow as possible to ensure the stability and functionality of that scenario.
  3. Strategy-based testing: This type of testing involves implementing the core testing methodologies into an exploratory test. In this test, the experienced tester would apply techniques like BVA (boundary value analysis), equivalence techniques, and more to the objects in the application.

How is functional exploratory testing different from structured exploratory testing?

1. Flow of the test

In structured testing, the flow of the test is directed by test cases that are prepared ahead of time.

Test cases are not determined in advance in exploratory testing and the flow is directed from exploring the system.

2. The objective of testing

The main objective of structured testing is to find foreseen errors whereas in exploratory testing the aim is to learn about the system and gain knowledge about its functionality.

3. Nature

Structured testing is predictive in nature as the flow of the test is predicted in advance.

Exploratory testing is spontaneous and investigative in nature. Tests are performed on a proper investigation is conducted.

4. The end results

The end results of structured tests are known and anticipated. However, the end results in exploratory tests are unknown and unexpected.

When to use exploratory testing?

The process is mostly standalone and can not be used to confirm the quality of any software product, it is always used to supplement the other testings. Some of the situations where exploratory testing will be very fruitful and helpful are:

  1. To understand how the application works including the look and feel.
  2. In cases where the testing bandwidth is very crunched, exploratory testing may be performed on the least critical or rarely used modules of the application
  3. Check out the new features and changes in the application after each new release.
  4. To help new testers to understand the application, and also to test the application from a fresh perspective
  5. To supplement the structured testing towards the end of the testing phase

Exploratory Testing Process

1.      Learning

This is the first step of exploratory testing and one which is very crucial. Learning about the system is important because you will be able to better analyze all the minor and major functionalities of the system and check it for bugs.

Your knowledge about the system will help you explore the system and create test designs and plans accordingly.

Unless you do not have knowledge about the system you will not be able to explore it in detail.

2.      Test Design

Tests designs are created spontaneously during exploratory testing and there is no need for documentation of test cases, scripts and the conditions of the test.

3.      Test Execution

Test execution is performed along with test designing. As soon as you plan and design your test you execute it without waiting for formal documentation. Only the key components of the test are recorded like the bugs that are detected or ideas for the next test.

4.      Analysis

When some bugs are detected on exploring the system, proper analysis and feedback are made in order to rectify the errors.

The previous test result feedback helps testers to prepare for future tests and apply logical reasoning to guide the future of the software testing life cycle.

Advantages of Exploratory Testing

  1. During the process, there is no preparation time required before a test. It saves a lot of time and effort from the testers as they can focus solely on exploring and learning about the system rather than preparing test cases and documentation.
  2. It allows testers to find critical and hidden bugs and errors that cannot be found through formal testing approaches. All the bugs which do not directly affect the system outputs and get overlooked during initial testing can be detected through exploratory tests.
  3. The results of the previous tests help testers guide their future tests and explore the system in a better and more detailed way. This speeds up the testing process and testers are able to find more bugs easily.
  4. Exploratory testing helps testers gain in-depth knowledge about the system. When a bug is found they can learn its scope, size, nature, etc., and provide better solutions to the developers.
  5. When the system under test is intricate, complex, and vast, exploratory testing may generate better results and prove to be more efficient in finding bugs than formal testing techniques.
  6. When there is very little time for testing a system, exploratory testing is the best way to detect bugs quicker and in more efficient ways. Lots of time is saved when the documentation process is eliminated.
  7. The most significant advantage of exploratory testing is that it helps testers learn about the system. Testers are able to develop and test the system for different scenarios and get to know how the system will perform under such circumstances.

Disadvantages of Exploratory Testing

There are some disadvantages related to exploratory testing which make it a little harder to implement.

  1. The tests that are performed during exploratory testing are spontaneous and not documented which makes them hard to review and keep for future references.
  2. Since there is no documentation involved, keeping a track of the tests performed and the functionalities already explored is difficult.
  3. Repeating a test performed during exploratory testing the exact same way again is not possible. This is a huge disadvantage when you need to repeat a test to find a specific error found in a previous test.

  4. Challenges in exploratory testing

    There are some challenges in exploratory testing because it is not structured. Let us check out some of the major challenges:

    1. Issue Reproduction: once an issue is found, it may be difficult to reproduce it, since there are no defined steps that the tester followed. To avoid this tester would either enable recording in the device.
    2. No Exit Criteria: It is difficult to decide when to stop the testing as there are no defined tasks that need to be completed before concluding the tests.
    3. Uncertainty in test coverage: There are no defined documents or procedures to capture what is tested and what is not tested. Hence the test coverage can not be determined
    4. No defined metrics or reports: There are no formal metrics or reports to substantiate the amount of testing or the success of the testing activity. Many times it becomes a challenge to convince the management of the effort involved and the purpose.

Steps in exploratory testing

Exploratory testing does not follow a particular structure; however, there are a few steps that are common to each exploratory test. The preparation of exploratory tests is a 5 step process:

1.      Learning and classifying errors

The first stage of exploratory testing is gathering the results of the previous exploratory test in order to learn the errors found in the past projects. Testers need to analyze these errors and understand the root causes of the bugs so that they can develop a test plan or strategy to test their system.

2.      Test Charter tool

Test charter is a tool that is used to run exploratory tests. The stakeholders define the scope of the test and risks that need to be found using the test charter. Thus the charter should tell testers the following things:

  • What tests should be performed
  • How the system can be tested
  • What risks should be focused on while exploring the system

3.      Time Box

Time Boxing is the practice of setting a fixed amount of time known as a timebox during which a tester or a team of testers work together to find bugs. The time box session should not be interrupted and the testers should only focus on testing the system.

The testers working in pairs or groups can come up with the most creative exploration techniques and device efficient solutions to the errors found.

4.      Analyzing the results

Once the testing process is completed, the results of the test are reviewed. The defects found are evaluated and testers learn the causes of the defects in order to come up with the best solutions.

5.      Feedback

The results are compiled and compared with the charter. This helps testers identify whether they have tested the system according to the stakeholder’s needs and demands.

Things to keep in mind for exploratory testing

1.      Understand the main aim of testing

Exploratory testing is all about learning about the system and understanding its core functionality by exploring unexpected system paths. During this process, certain unforeseen bugs are detected.

2.      Planning the test is very important

Although test cases are not pre-defined during exploratory testing, it does not mean that exploratory tests are completely unplanned. Testers study the system and previous test results in order to figure out and plan their test. This helps them save a lot of time as they know what they are looking for.

3.      This is skill-based testing

Testing skills are an essential part of exploratory testing. Testers completely rely on their skills in order to explore the system and test it for defects. Therefore exploratory testers should be highly skilled and have good knowledge of all software testing techniques.

4.      Keeping a record of the test can be very beneficial

Even though exploratory tests are not documented, recording the findings, results, and defects found or any other outcomes of an exploratory test can be very beneficial.

5.      Exploratory testing should be a team activity

It is always better to perform exploratory tests in pairs or in a team. This helps testers to come up with better test plans, exploration techniques, and solutions to the defects found.

Example for Exploratory testing

The below image is an indication of how test cases are created for checking out the functionality of a web app. 

Exploratory testing example

Exploratory testing documentation

  • Keeping documented through notes is an effective way.

Eg:  *NEW* /LIVE/ “Browser: Login with  Gmailfirefox” (23-july-2021 09:44:20)

newUser@gmail.com

Client id = 357

https://mail.google.com/mail/u/0/#inbox

Login page displayed => OK

Previous account name displayed => OK

Login => OK

Logout Button available => OK

</OK>

  • Mind Map style

You can use web-based tools such as XMind7 to document the process.  The conventional mind mapping technique would not work in this case.  Create all the test cases as nodes and can be saved into a template. Data such as environment, date, execution browser, time,  the theme of the site, input data, environment, output data

Exploratory testing vs ad-hoc testing

Exploratory Testing

Adhoc Testing

Testing is carried out without much knowledge about the software but in a formal way

Complete freedom in testing the software

Documentation is mandatory

Not that important

Charter directed testing

No particular plan

Maximum test cases are executed

No need for test cases

Form of positive testing

Form of negative testing

Helps in learning the application

Helps in developing innovative ideas in testing

Does not need much time to commence

Needs preparation time

 

Conclusion

It overcomes all the shortcomings of structured testing. It helps testers detect errors that go unnoticed during scripted tests as they do not directly affect the outcome or working of the system.

This is the reason exploratory testing has become a very popular testing approach, especially for complicated systems. Exploratory testing has many advantages over scripted testing and helps testers focus on gaining knowledge about the system.

There are some clear advantages and benefits to be a beta tester. The last advantage is that you get to have an early look at all of the interesting and fresh new features that will come with the PlayStation 4 v5.5 firmware update. The previous year, beta testers for the v5.0 update got a sneak peek at the new features, like the enhancements for Twitch streaming on PS Pro platforms, updates to Family account to Family account management settings. In addition to being privy to the plans Sony has for the next big update, beta testers are also awarded an exclusive PSN avatar.

If you determine to be a beta tester for Sony, and you end up hating certain aspects of the new firmware update, don’t worry; beta testers have that capability to “roll back” their firmware to previous versions. Another advantage is that successful beta testers can select to be registered automatically for the next round of console testing.

At present, nobody is certain about the exact features that are to be the highlight of the latest firmware update, or which of the PlayStation application and games will be improved. However, if you are very curious regarding beta testing and you meet all of the needs set out by Sony which are mentioned above, it might be worth your while to give it a shot.

How to Become a PS4 Software Beta Tester?

The first step to becoming a PS4 Software Beta Tester is signing up for the Play Station 4 System Software Beta. Given below are the steps that can help you to do so.

1. Visit the Sony’s official website page where you can sign up as a PS4 software beta tester.

2. Sign-In with the E-mail address that you have given when you created your Sony Entertainment Account and the password of your Sony Entertainment Account.

3. Click on “Sign in” and you will be led to the Enrolment Form

4. Read the Private Beta Trial Agreement and, click yes

5. Finally, click on “Submit”

Not sure if you should take the plunge? Well, there are some things to bear in mind before you sign up:

1. Places are limited. Sony might have opened their gates to more testers, but it’s not allowing everyone to jump in and experience the new beta firmware all at once.

It is open only to the PS4 master accounts. No sub-accounts are eligible to take part.

2. The PS4 should be supported by an active Internet connection. This is because Sony will not be distributing the beta firmware as a downloadable file from its website.

3. It is advisable that you do not install the beta firmware, especially for the safety of your saved games and/or installed software. The instability of the beat firmware might lead you to experience odd quirks while using your PS4.

4. You can always roll back to a previous version of the firmware if you are unsure of staying in the beta.

On a central portal, an open invitation for beta testers was declared. Sony has earlier opened up early versions of their system updates to beta testers, but one basic difference this year is that testing is now open to Canadian gamers.

Previously, beta testing was exclusively available to individuals residing in the United States. Sony is even about to extend beta testing to gamers in Japan, but applications for this region are not yet available.

If the prospect of becoming a beta tester for the new system update for the PlayStation interests you, there are just a few primary things you require. The initial requirement is obviously that you have to already own a PlayStation 4.

You even require to have a stable internet connection, as well as a Sony Entertainment Network or PlayStation Network account. It’s even compulsory that all beta testers are at least eighteen years of age.

Defect Triage: All You Need to Know is here!

Posted on by tbsupadminnxtbackendacc

What is Defect Triage?

Defect Triage is a process where the testers find out the bug and assign a degree of risk, re-occurrence, and severity to it. This degree essentially prioritizes the bug to be treated first.

Triage however is a medical term which basically means trial or a try-out. When you arrive at the emergency department, your first medical evaluation is done by a nurse.

defect triage

In the emergency department, it is typically done in the triage room. During this time it is very important that the patient describes their problem to the nurse so that she can accurately assess what needs to happen next.

Based on the severity or urgency of another person’s medical condition, they may be taken back quicker than you. This is exactly what happens when a software tester runs a defect or bug triage.

They assign a severity degree to each bug and the bug which seems more severe or the bug which has more potential to compromise the integrity of the system is taken into consideration first.

Defect Triage Meeting

Triage meetings are facilitated by the QA lead and it is coordinated with business analysts, IT lead, project manager, or even the product manager.

During the development or testing phase, testers come across a lot of issues or bugs which keep bothering everyone. To take care of these bugs, the defect triage meeting is organized.

The main objective of this triage meeting is to categorize, prioritize, and track issues.

Triage meetings happen every so often, sometimes even 3 – 4 times in a week depending on the size of the project, project situation, schedule, and number of defects. Multiple factors play a role in determining the number of triage meetings needed to eliminate a bug once and for all.

All these meetings involve discussions of complexity of the defect, risk involved in it, assignments, re-assignments, and rejections. All these updates are captured in the bug tracking system.

For the best results, QA lead should send out the bug report with the existing defects or new defects for every meeting.

Each defect should be analyzed to see whether correct priority and severity has been assigned. The main motive of this meeting is to fix all issues in a timely, fixed, and accurate manner.

During the meeting, each bug is categorized in one of the three categories:

  • IMMEDIATE ACTION TO FIX THE BUG: The defect falls in this category because of two reasons. The first reason is that there are sufficient resources with the team to fix the bug and the second reason is that the bug might cause problems in the future therefore it is important that they fix the bug immediately.
  • ACTION ON THE BUG AT A POINT LATER IN TIME: A bug falls in this category when the team knows that it is not something major and can be treated after some time.
  • NO ACTION BUG: This basically means that the bug is very minor and doesn’t have any effect on the whole system. Therefore, there is no need to take an action on such bug.

Steps in Defect Triage

The triage team consists of project manager, tester, test lead, developer, environment manager, test manager, and business analyst. There are 3 steps in defect triage; defect review, defect assessment, and defect assignment. Each of the steps is discussed in detail below:

  • DEFECT REVIEW: All the personnel mentioned above dive deep into the origin and consequences of each defect in an attempt to fix them.
  • DEFECT ASSESSMENT: In this step, the defects are categorized into 2 categories; to be fixed and on hold. The severity of the defect is the main basis of this segregation. The above mentioned personnel collectively make the decision on which defect to treat immediately and which defect to be kept on hold.
  • DEFECT ASSIGNMENT: Now that the team has a list of defects that need to be treated first hand, they assign each defect to the concerned person. All this is done after the defect has been properly and comprehensively evaluated.

Roles and Responsibilities of Each Member in the Triage Team

  • TEST LEAD: The test lead is the one who starts it all. Test lead sends a formal invite to all the triage members along with a detailed defect report. The test lead is the first person to identify and assign a degree of severity to each defect. One of the main responsibilities of the test lead is to prepare a presentation for the triage team which would give them more insight on each defect. This presentation helps the team members to get to the root of the problem quickly.
  • PROJECT MANAGER: The project manager plays a pivotal role in prioritizing defects, making the defect list, and mediating the whole meeting. He also ensures that all the members of the triage team are present for the discussion. Sometimes the discussion heats up and that’s where the project manager steps in to allow the team members express things from their perspective.
  • DEVELOPMENT TEAM LEAD: Development team lead and project manager collectively prioritize defects. The main function of the development lead is to communicate the risks involved and the complexity level of each defect. Also, he is the one who assigns tasks to different members of the triage team.

There are other members in the team but the project manager, test lead, and the development team lead are the key persons. The meeting would not reach a conclusion if any of these is missing.

What Happens in a Triage Meeting?

 

defect triage meeting

The defect triage meeting is divided into 3 parts; pre-meeting, during meeting, and post-meeting. Before the meeting starts, the test lead sends a report to all the members of the triage team so that they are aware to some extent about the latest bugs.

  • PRE-MEETING: Testers have a key role to play in the pre-meeting. Testers give information about the bug to the team and they categorize each bug in different sections on the basis of severity and priority. So basically, the pre-meeting session is owned by the testers.
  • DURING MEETING: It doesn’t always happen that all the issues in a meeting are resolved. Some pending issues from the previous defect triage meeting are discussed before moving on to the new issues. Then the progress on previous issues is discussed. From this point forth, every point is noted down about the severity of the existing defects. The team members collectively make a decision on which defect to be fixed immediately and which defect they can postpone to a later date. If the deadline is near, the bugs with a higher degree of severity will be treated first and the less severe bugs will be kept on hold. However, if there is no pressure of deadlines, even the pettiest bugs can be fixed in the starting of the project. Based on this, the bug list is updated and this is where the assignment of tasks comes in. The test lead has the last word in the meeting. He quickly summarizes the whole meeting and communicates the immediate courses of action to respective team members.
  • POST-MEETING: MOM (minutes of the meeting) is shared to the defect triage team after the accomplishment of the meeting. This document contains the key points discussed during the meeting.

Contents of a Bug Triage Report

  1. DEFECT ID: Each defect has a unique number assigned to it which differentiates it from other defects.
  2. DEFECT DESCRIPTION: This is related to how the defect causes malfunction in the system.
  3. CREATION DATE: It is the date on which the bug was noticed for the first time.
  4. CREATOR: Creator is the person who first noticed and reported the defect.
  5. SEVERITY: This is a measure of how severe the bug is.
  6. PRIORITY: The priority could be high, medium, or low. High priority means that the bug requires immediate attention, medium priority means that the bug can be resolved after sometime and doesn’t require immediate action, and low priority means that the bug doesn’t have any significant or noticeable impact on the project and therefore may or may not be resolved.
  7. STATUS: Whether the bug is new, under review, in progress, or completed is determined by referring to the bug status.
  8. ASSIGNMENT DATE: This is the date on which the bug was assigned to the respective personnel for resolution.
  9. ASSIGNED TO: This field has the name of the person to which the bug has been assigned for resolution.
  10. RESOLUTION: What is being done to resolve the bug.
  11. DATE OF RESOLUTION: Estimated date on which the defect will be completely resolved.
  12. ESTIMATED TIME: Speculated time of resolving the defect.
  13. ACTUAL TIME: Total time elapsed for resolving the defect.
  14. ROOT CAUSE DESCRIPTION: This field has information related to why the bug appeared in the first place.

Why do We Need Defect Triage?

The main benefit that you gain from the process is that your team will get to evaluate the severity of the bug, devise plans to fish it out and come to a conclusion regarding the resources that need to be allocated for the process. Defect triage is mainly used in agile testing methodology

CONCLUSION

To resolve the defect, a defect triage meeting is called. The test lead, project manager, and development team lead must be present among all the triage team members.

The defect triage meeting is completed in 3 stages; pre-meeting, during meeting, and post meeting. After all this, the test lead prepares a detailed triage report.

The report has all the information starting from when the defect was initially noticed until the root cause of the defect.

The frequency of the defect triage completely depends on the size of the project. It can be organized on a weekly, monthly, or daily basis.

Mainframe Testing – What Happens?

Posted on by tbsupadminnxtbackendacc

Here is everything that you need to know about Mainframe Testing – what it is and what is the process that is followed, essentially a complete beginner’s guide to Mainframe Testing.

What is Mainframe Testing?

Mainframe Testing is the process of testing Software Services and Applications that are based on the Mainframe Systems.

The process is crucial part of the Application Development Process as it is instrumental in adhering to the cost and quality standards of the industry.

Mainframe Testing ensures that the system is in fact, ready to be launched in the market.

What are the steps followed while undertaking Mainframe Testing?

  • Smoke Testing – Also known as Shakedown, this is the take-off point of the process of Mainframe Testing. Before any action is taken on the codes that are to be used, this first step is to ensure that all the codes that have been deployed are actually in the right testing environment.
  • Only after the adaptability of the code has been confirmed, and the codes checked for any critical technical glitches, are they approved to be worked on in the later stages of the Mainframe Testing Process.
  • System Testing – This stage involves a series of testing that is undertaken to test the functionality of individual systems that comprise the Mainframe system, as well as their performance with respect to each other.
  • Batch Testing – The Batch Jobs begin by testing the scope of data and files, recording the results and making changes wherever necessary. The Batch Testing is the stage where the validation of the test results on output files and data as done by the batch jobs take place.
  • Online Testing – While the Batch Testing can be loosely understood as the back-end testing phase, with Online Testing, the testing moves to the front end of the mainframe application. The Mainframe Application is tested here in relation to the entry fields that are used by the system.
  • Online-Batch Integration Testing – This stage bridges the gap between the back-end and the front-end of the Mainframe System. Through this integrative testing, the data flow, as well as the interaction that takes place between the online screen and the batch job, is validated and approved before being passed on to the next stages of the Mainframe Testing process.
  • Database Testing – At this stage, the database of all data for the Mainframe Application is stored is validated for the layout of the data storage.
  • System Integration Testing – Once the basics have been covered, System Integration Testing is initiated to test the functionality of the system under test and their response to, as well as their interaction with other systems. This is rather a broad spectrum and is prone to be considered as unnecessary, but it is an essential step as it ensures that the new system integrates with other systems in an organized manner.

The relationship between the different systems here is not in terms of either being affected by the requirements of the other.

But in the sense that each use data that is being collected, stored or managed by the other systems.

Hence, testing the exchange of data takes place, and how commands and results flow from one system to the other is essential to create a streamlined integration process between different systems.

Again, the different types of testing processes that are used for System Integration Testing are Batch Testing, Online Testing and Online-Batch Integration Testing (as discussed previously).

  • Regression Testing – This can be understood as the counteractive stage to the previous one. While the System Interaction Testing ensures that the different systems that comprise the Mainframe function simultaneously and are conducive to the performance of the System as a whole, the Regression Testing is a way to ensure that the different systems do not hinder the performance of each other.

Each system should not only be involved in the functioning of the other, as long as it is beneficial for both of the systems. Therefore, Regression Testing is responsible for making sure that the batch jobs or online screens, for instance, do not negatively affect the system that is currently being reviewed or vice versa.

  • Performance Testing – Once we know that each system that is currently at work is doing its job in relation to the new system, or an update being tested and that the new system under test does not hamper the functionality of an existing system, the next step is to test the performance of the system in its specific environment. It involves identifying bottlenecks in high hit areas like the front end data, or other activities like upgrading online databases and to check and understand the scalability of the application.
  • Security Testing – When it comes to software or well any Technology for that matter, the first question that needs to be answered is whether it is a secure platform or a safe space for the users. The same goes for the Mainframe Testing process. Before approving it for being used in the system, it is important that the system is tested to see how it fares against the security attacks. Security Testing is a stage that evaluates the design and development of the application and its ability to withstand potential security attacks. It includes the system’s independence in countering those attacks and keeping all information and data entrusted to it, absolutely safe. The two most common types of Security Testing that need to be undertaken are the Mainframe Security and Network Security. The features that both these tiers of security tests, check in their specific ways are – Integrity, Confidentiality, Authorization, Authentication, and Availability.
selenium

This is the basic model that is followed by testers when it comes to Mainframe Testing.

While specificities might vary depending on the particular project at hand, the basic outline that is to be followed remains the same. As with every other aspect of Technology, there is enough room to negotiate or experiment with this industry standard.

Experimenting and exploring unchartered territories though might lead to dead ends or tunnels that don’t always end with light.

But you can always trace your steps back, and find out where you went wrong and take corrective measures as and when required.

The next section focuses on the challenges or problems that are faced by the Mainframe Testing team and how can they find their way out of a tight spot.

What are the common challenges faced in the process of Mainframe Testing?

Each and every kind of Testing is a series of hit and trial until you arrive at the best possible system. Mainframe Testing is no different. Though we have discussed the steps that are generally followed during the process of Mainframe Testing, even the closest adherence to these steps do not always ensure the best solution in the first attempt.

There will always be challenges or troubleshooting that the testing team will be faced with during the process.

Discussed below are some issues that have been often reported by the testers and the possible approach that can be adapted to find a solution to that problem.

  • Unclear Requirements

Problem – It is extremely important to have clearly set requirements before you working on any testing project. While a supporting manual might be available, it does not always cater to the demands and needs of the project at hand. The problematic of unclear, incomplete or impractical documentation is a problem that hinders the testing process.

Solution – The testing team should be actively involved in the Software Development Life Cycle right from the time when Requirements are being set for the system. Their involvement in the early stages will ensure that they can verify that the requirements that are being set are after all testable and practical. This saves time, money and efforts of the team, while also ensuring that the Software Development Process does not come to a standstill at a later point in the testing phase.

  • Ad-hoc Request

Problem – it may so happen that upstream or downstream application issues might necessitate end-to-end testing needs. These unexpected requests have the potential to disrupt the pre-defined schedule of the testing process by increasing the time, efforts and other resources required in the execution cycle.

Solution – To provide for the unforeseeable issues during the testing process, it is advisable to have automation scripts, regression scripts, skeleton scripts and any other backup plans to implement immediately as and when faced with a problem. This considerably reduces the overall time and efforts required for the completion of the project.

Here goes your basic guide to Mainframe Testing. This is not an exhaustive guide, there is always more that we can learn, and there is always room for improvement and efficiency. Keep exploring.

What is Data Driven Testing? How to Create a Data Driven Automation Framework

Posted on by tbsupadminnxtbackendacc

What is Data Driven Testing?

Data Driven Testing is an Automation framework where we can alliteratively run multiple data set from an external source like a table for the same test script-instead of hard coding.

Multiple data sets and test environment can be controlled and run without hard coding and results obtained can be compared.

If data is hard coded it is highly tedious, monotonous and inefficient to run the same test script for different data set.

This becomes easier when data from different sources can be fed as input, this input gets verified and result outputs obtained can be compared.

data driven testing

Types of Data Driven Testing

Data-driven testing can be broadly classified into three parts:

  • Data-driven scripts: Data-Driven Scripts are application-specific scripts (like JavaScript) that are coded to include variable data sets.
  • Keyword-driven test automation: Keyword Driven Test Automation is also known as Table Driven Test Automation. In keyword Driven test automation a data table using keyword id deployed for testing
  • Hybrid Test automation: It is a blend of Data-Driven and Keyword Driven Automation Frameworks.

Why Data Driven Testing?

Data-Driven testing tests application with multiple data sets ensuring extensive testing. It also allows in organizing Test data and validation data in a single file.

Example:

For example, we have a login system that has to be tested for multiple input fields with different data sets.

We can test it using different approaches:

Approach 1) For every data set creates separate scripts and execute each of it one by one.

Approach 2) Every time you have to run the test case for different data set, annually change it in the test script and execute it for all required number of data sets.

Approach 3) Import the data in an excel sheet and fetch this data one by one from the excel and run the script.

Executing the test scripts using approach 1 and 2 are very time consuming and lengthy process, the third method or what we call data-driven framework is ideal for such scenarios.

 Importance of  Data Driven Testing?

In real life applications with frequent changes in data set such as addition, modification and deletion of data, hard coding data makes it difficult or almost impossible to run each time.

Data Driven Testing makes it much easier to use and maintain voluminous data individually in tables.

Manually to cover all the scenarios, a tester may have to design multiple test scripts or edit existing test scripts multiple times and run it individually.

Thus, making this difficult or almost impossible task. For a Manual Tester, it is humongous and monotonous.

That’s exactly when Data Driven Testing comes to the rescue. Test Data can be fed from a table or other sources, independently without making changes to the test script.

All these data run for the same test script iteratively and results obtained can be compared.

Procedure Simplified

Test data are stored in an easily maintainable manner like tables or rows and columns and then passed as input variables to the AUT.

Test scripts and Data Provider are two separate entities having no direct impact on each other. Verified results from each test execution are then compared from expected results of the Data Provider.

Data Provider

Data can be fed in different forms. Few popular ones are

  • Internal table
  • Spreadsheet
  • CSV file
  • XML file

Data Driven Script

Scripts containing hard-coded data can be tough to maintain and sometimes they can break the execution.

In Data Driven Testing Test scripts and Test Data are separated and made into separate entities.

Hence Data Provider is independent of test script and both can be modified individually without impacting each other.

Real Life Citation

We shall take an example of online registration form. Data from Registration forms increase frequently sometimes every day. Each User registration add data rows in database.

1.Let’s take a simple form with Name, Email, Password and Confirm Password

2. Test Scenarios are identified and test cases are designed.

3. For now, consider only happy path – validating that data in table and actual result are correct.

4. Now let’s feed multiple data from a spreadsheet, csv file or the like as a table as below

5. During Test execution test script is run and data is taken from the table.Each data is executed one after the other in iteration row after row.

6. Once script is executed, actual results and expected results are compared.

7. Notice that data has been modified – added newly at the end of the table, edited existing in the middle row and deleted in-between the table.

This can be easily done by modifying the Data table like below without touching the script.

This can be easily done by modifying the Data table like below without touching the script.

8. Data has been modified easily without changing the script.

What is the Difference between Keyword Driven Testing and Data Driven Testing?

Difference between Keyword Driven Testing and Data Driven Testing

In Data driven testing test scripts are executed for a different set of data to validate proper working of application with different variable values. Here data is used as inputs to your test script. Every data contributes to a test case and hence with every different test data you have a different test case.

On the other hand, in Keyword-driven testing, a keyword represents action. A set of keywords drives a script. These keywords build test scripts.

Example of Data Driven Testing

Example of Data Driven Testing

Let us understand data driven testing more deeply by taking an example of a Login Page of a Flight Reservation

1) Create a test data file in Comma Separated Values and name it as TestData.csv

2)  Inputs for driver script and expected results are stored in this file.

3) Create a driver script for the data file as

data = open(‘TestData.csv’).read()

 lines = data.splitlines()

4) Steps for data script will be

  • Read Value1
  • Read Value2
  • Read Operator

5) Calculate the result

6) Compare the expected result with the actual result.

Advantages of Data Driven Testing

  • Test Data can be stored in a single file making it easy to maintain, monitor and track.
  • Test Data and Test scripts are separate entities. Hence changes in one does not impact the other.
  • Large volumes of data can be executed thereby improving Regression testing and better coverage
  • Smoother maintenance of test scripts making addition, editing and deletion of data rows easy and hence less time consuming
  • Manual effort involved is less and hence it is cost effective

Disadvantages of Data Driven Testing

  • Requires great expertise of scripting language
  • Each time a new test case is designed and a new driver script will be required with different data so that the changes made to the test cases should reflect in the driver script or vice versa.

Conclusion

Data Driven Testing a very good strategy if we have huge volumes of data to be tested for same scripts provided there is a highly skilled testing team. And it does not suit projects that do not have much work with data.
