Test Environment: What is it? How to make it effective?

Posted on July 28, 2020 by tbsupadminnxtbackendacc

Test environment is the proper set up of hardware and software crafted for the testing teams for executing test cases. Test Environment helps in supporting text execution with network, software, and hardware configured. The text environment is primarily configured according to the Application Under Test requirements.
There are some instances when the testbed proves to be a perfect combination of test data and test environment that it operates on. Setting up a perfect test environment ensures a higher success rate in software testing. Any related flaw will lead to excess time and cost.
This article talks about the test environment in detail, along with the process, types, and benefits involved. Stick to the end for complete detail.

Major areas to set up one testing environment:
There is a key area that needs to be set up for the testing environment. Those sections will include test data, applications, and systems, database server, browser, client operating systems, and front-end running environment.
It even talks about the hardware that includes the Server Operating system and network. For covering the testing environment, there is a necessary step associated with documentations like configuration guides, reference documents, user manuals, and installation guides.

The process involving a software-based test environment setup:
Tests are limited in nature. To perform the test well, you need a team of developers, testers, system admins, and users or techies with an affinity towards testing. It is true that the current test environment needs to set up multiple numbers of some distinct areas. Some examples are listed below for better reference.

Setting up a test server:

It is true that you cannot execute all tests on the local machine. For some, you have to create a test server to support applications. For example, you need Fedora setup for Java-based and PHP apps with or even without a mail server.

Crafting test data for the environment:

Multiple firms are currently using separate forms of test environments for testing the software item. The common example is the “copy production data” for testing out. It will work well for the tester to help detect similar issues like that of a live production server. It can be done without corrupting present production data.
The current approach for copying production data for testing data will include setting up production jobs for copying data to the common testing sector. Moreover, the PII will get thoroughly modified with some other sensitive data. It is replaced with non-personal yet logically correct data. The copying production data will also help to remove data, proven to be not valuable for the test.
Developers or even the testers can even copy this to an individual test environment. They can easily modify the same as per the chosen requirements. In the case of copy production data, privacy holds a big value. For overcoming any such instances, make sure to keep a check on complicated testing data.
There are two approaches available for the anonymization of data. One is a blacklist, and another one is a whitelist. Moreover, if you are using the current production data, you must know ways to source it. One effective approach is by querying about the current database by using SQL script.

Network:

The set up for the network will also vary based on the test requirements. It comprises LAN Wi-Fi setup, Internet Setup, and Private network setup. The main goal is to ensure that the congestion which took place during testing will not affect any other member, such as content writers, designers, and more.

Bug reporting:

Testers are in need of bug reporting tools. There are many available nowadays, and testers must head towards the upgraded versions only.

Testing the PC setup:

You need multiple browsers for web testing to cover different testers. In terms of desktop applications, you need various OS types for multiple PC testers. In case of windows phone app testing, for example, you will need a Windows Phone emulator, visual studio installation and also need to assign windows phone to the tester.
Heading towards types of testing environments:
You will come across multiple testing environments forms and types. The one that you need solely depends on the test cases. It also depends on the application under the test. For example, any thick-client desktop-based app will have a different need when compared to a web app. So, the test environments that you need for a desktop app will differ from web application ones.

Chaos testing environment:

The primary aim relating to chaos testing is to understand how individual parts failing can cascade potentially and ruin the entire system. For that, the software teams will be working on fault injection methods. It helps them to create a thorough understanding relating to the present major dependencies relevant to the system and how the software ended up failing.
For example, if you have a modern web app within micro-service architecture, then setting up a reliable chaos test environment is mandatory. Here, the environments must be settled in the same manner as the production environment. They must also get configured for high availability.
To improve the entire system’s reliability, it is vital to have a separate environment to test disaster recovery, business continuity, and high-availability. The testers must also test how dependent services will behave in failure modes. To run these tests, you can focus on disaster recovery drills or game days. It helps to identify potential weak links in large-scale and modern apps.

Security testing environment:

The service is completely different in security testing environments. Here, the main job purpose of the security team is to ensure that the software will not have security flaws and any weaknesses in integration, confidentiality, authorization, authentication, and non-repudiation.
Here, the main purpose of chosen firm is to engage in a thorough combination of external and internal security experts. They primarily specialize in software-based security vulnerabilities. At this stage, it is vital to establish a thorough scope to define what the system is targeted for. They will talk about used methods and the time for assessment to occur.
There are certain ground rules that you must establish as a major part of the security testing environment. You must have an isolated testing environment and non-disclosure agreements. Moreover, you cannot leave the system in the worst state and should not touch production data. It is primarily application while engaging external based security companies.
Security tests can take place in multiple stages and frequencies. A successful team will always execute vulnerable assessments, audits, scans, and some other non-invasive tests. For maintaining a security baseline, security testing works great beside integration tests.

Performance testing environment:

You can use a performance testing environment for determining how well any system gets to perform against any performance goals. The goals can be stability, throughput, response time, and concurrency. This testing is a broad term and will include load, volume, breakpoint testing, and stress.
Good performance testing environment plays a major role in benchmarking and also identifying bottlenecks within the system. The setup remains fairly complex. It mainly requires careful configuration and selection of present infrastructure. You can run multiple tests on various environments by RAM size, CPU core numbers, data volume, concurrent users, and more.

Integration testing environment:

Here, you get to integrate individual software modules and then verify its behavior. There are sets of tests available, designed to check that the system behaves as mentioned in necessary documents. You get the chance to add one or more application modules and verify functional correctness.
The setup will always depend on the application type and components as being tested. Setting up such environments will involve ensuring the right hardware availability, software version, and right configuration. Such testing environments must mimic production scenes well. It will include database, web servers, application server management, and more.
Thanks to the modernized DevOps approach to the field of software development, continuous testing has become a norm these days. It is widely used multiple times a day. So, it has the power to recreate the environment to define the software delivery process.

Benefits revolving around test environment:
You must be wondering why people are integrated more into the test environment these days. You will receive a greater test case definition and can be a proficiently, skilled testing engineer. But for harnessing the power of test cases, it is vital to have a well-designed testing environment.

A proper test environment helps to offer proper feedback regarding the behavior and quality of the app under test.
It even offers you the needful setup for running test cases.
You can enjoy the services of a test environment to create a dedicated environment for isolating code and verifying the behavior of the application.
This section ensures that other activities won’t be able to influence the tests’ outputs as running on the server.
Any test environment will work as a proper copy of the production environment. It forms a crucial element for you to be confident about testing results.
It is mandatory for the testing engineer to be 100% sure about an application that behaves in the same way in the test environment and in the production environment.

The vital use of the test environment is to free testers in modifying data without affecting any real information. The test environment provides the freedom to convince you of your worth in the development process. Here, you get to expand the testing scope to add necessary and bizarre tests, which are not possible otherwise.
It is true that test environments prove to be mandatory in the testing process. It ensures that consumer data always remains safe and also offering a true reflection of the real-world system.
Major elements to create a test environment:

It is necessary to focus on some major elements while creating the right test environment. Make sure to create a list first of the requirements and complete every one for creating the best test environments.

Remember to create test data and then insert it to the testbed. You need to take some steps to set up a database too.
Make sure to configure the environment as other key elements for creating a test environment.
You have to select the right OS and hardware. Remember to take time and evaluate the differences between running apps on Windows 10 and Windows 8.1.
You need to take some time to configure the network. Let’s get to know about cross-original resource share, for example.

You have to document all the necessary actions you are focusing at. This is mandatory for the other users who can replicate the environment. In the same way, detailed documentation will later help the testing engineer to set up various test environments like production environments and staging.
Activities taking place in test environment setup:
There are some interesting activities, as performed for testing environment setup. Remember to focus on those points before finalizing the testing activities.
Design test environment:
Some factors play a major role in designing the test environment. It helps in determining if the test environment needs archiving to take back-ups. It can also verify network configurations and identify required server OS, database, and more.
Setting up the environment:
The team often needs to analyze environment setup requirements before preparing a list of hardware and software requirements for the initial setup. You will receive the official confirmation for present testing sector setup for accessing it later.
Importance of smoke testing:
Whenever the environment is set up, it is time for the QA team to access it. The members of this team will perform smoke testing for validation of the test environment and building its stability. If they get the expected results, then they will move to the next phase. They might also point out some of the discrepancies, if any, and wait for the deployment after the fixes are covered.

Why is it hard to hire versatile testers? What’s the solution?

Posted on July 16, 2020 by tbsupadminnxtbackendacc

The quality of software decides its success. We are at a juncture where quality matters the most than anything. When it comes to people who are responsible for the quality, there is a huge scarcity. And it’s a big problem!
Let’s have a few statistics that might reveal an important question

The most accepted tester to developer ratio is 1:4.
Requirement volatility and lack of skilled testers are some of the biggest problems when it comes to test execution challenges
69% of testers working in the organization agreed that formal training is required
24% agreed that they got into testing accidentally
65% of testers agreed that they have never been formally taught

Is there a fertile ground to nurture skilled testers? The answer would be no!
There are certificate courses on software testing. True that. But, is that enough?
We are moving to a phase where software quality has of utmost importance to be successful. So Quality assurance has to be given prime importance and nurturing tester skills has to be done ASAP.

An Ample Hiring example
Suppose a company is diligently looking for an automation tester. But, when it comes to the responsibilities of a tester, don’t you think he has to do much more than that of being proficient in tools?
Automating time-consuming tasks such as writing script and maintaining a test environment has to be done to make sure there is a stable agile/DevOps environment. His duty does not end there he has to be the central part that grantees efficiency in any project.
In short, software developers are adding features on a constant basis to keep up with testing there has to be testers who can think out of the box.
But unfortunately, we are at a dilemma where the supply of such skilled testers is in scarce considering the demand.
The organizational dilemma in QA
There exists a situation where developers perform QA to make sure that SDLC is at its right pace. One of the major reason would be the few software testing companies to choose from considering the humongous number of software development companies.
So what happens when developers becomes tester is that, most of the time developers tend to leave their codes unchecked resulting in a bottleneck at any point in the development.
So it’s an urgent requirement that we need companies who can efficiently test software and can be in the loop when it comes to continuous development.
Most of the testers are self-made out of sheer hard work and perseverance
Only 44% of testers across the globe have been formally taught. The rest of them learned with the help of books, video tutorials, and through experience.
But there is a huge problem here. Experience = time. A person who has started his testing career or if he is someone who is interested in QA will require years of experience to master the craft. Learning theory alone most probably won’t land them a job either.
Be it fresher’s, we need testers who can get into the process within a short span of time.
What’s the solution here?
Make sure that testers are deeply trained and nurtured in a way that they become more than mere testers. They should have a holistic approach to software quality rather than able to carry out certain processes.
What are the basic traits an organization will be looking for in hiring testers?

Knowledge of DevOps and Agile Methodology

With software expected to be delivered in a short time period, testers should be knowledgeable about these collaborative as well as iterative working modules. Agile methodology offers testing speed, whereas DevOps provides cross-functional teamwork from the outset.
2. The Efficiency with Web and Mobile Technologies
A tester must have a strong understanding of the latest mobile and web technologies. The knowledge will allow them to understand the particular application and related specifications in order to apply effective testing actions.
Testers must update themselves of the advancements in the web as well as mobile technologies. Their level of awareness is what helps them understand the coding structure and technical pitfalls to extend relevant Q/A solutions.
3. Rational Analysis and Logical Thinking
Testers must be logical, analytical, and rational because these skills when applied to tests, enable them to determine errors, comprehend challenges, assess irregularities within the application, and perform testing accordingly.
Moreover, these skills also help them to validate application against various scenarios and test its performance and elements against the predetermined standards.
Having a logical approach further allows testers to interpret the information, highlight relevant questions, and identify strengths and weaknesses, and eventually implement the right course of action.
4. SDLC
Software Life-cycle Management Skills or SDLC allows testers to understand the tasks and plan testing cycles of an application. Having a thorough understanding of the SDLC cycle helps them to figure out complexities within the application.
By determining the issues in the early stages, allows testers to take the right measures at the right time.
In this, testers must essentially learn certain development methodologies, including Scrum, Waterfall, Lean, and Kanban.
5. Programming
Understanding of programming languages helps testers understand an application’s inside out. The ability to comprehend every aspect of the application is what makes a successful tester stand out from the crowd.
The knowledge of programming language assists testers in efficiently determining potential errors within the code, thereby reducing the chances of inefficiencies and bugs.
6. Communication Skills
By imbibing good communication skills, testers will be able to interact with the clients and clearly make them understand the status and requirements of the projects.
Moreover, testers will be able to communicate issues with the development team and translate the technical reports in an easy way to help the management team understand the process.
Additionally, good communication skills help testers provide insights and feedback to both technical and non-technically teams in a more understandable manner.

Final take
The answer is simple. Many budding testers are not aware of the huge paradigm shift that has happened or is happening when it comes to quality assurance. Organisational requirement is entirely different from what most of the testers have learned.
Rather than being a part of a module, software testing has to be taught in its entirety as a full length bachelors or master program so that when it comes to hiring freshers companies will have much more reliable medium than going through the painful experience similar to finding needle in a haystack.

Jmeter Tutorial: Learn about the tool in a jiffy!

Posted on July 6, 2020 by tbsupadminnxtbackendacc

Jmeter Tutorial blog by us will help you in learning about the famous tool and what’s it is used for. Usually, Apache JMeter is used for performance testing. Performance testing is one of the important testings to be performed on AUT. It will let you know the load which your application can handle and what happens if that load exceeds prescribed limits.
Through, meter tutorial let us know more about JMeter and see how it can be used for performance testing.

About JMeter – Jmeter tutorial introduction
JMeter is an open-source software which is designed by Apache Foundation. It is used to apply load to AUT to know its performance. With the help of JMeter, you will be able to apply a heavy load to the application with concurrent or multiple traffic to emulate real-time user behavior.
For applications such as Amazon who release flash day sales, it is very important to do performance testing. On a single day and in a time interval of 5 mins many customers hit the site and we must make sure that the application behaves expectedly without any flaws. One more application where performance testing is very important is the railway ticket booking website where a large chunk of people hit the server at the same time. In these cases, it becomes very necessary to test out the website under heavy load.
JMeter is usually used for testing of web or FTP application. With JMeter, you will able to identify how many concurrent users a server can handle. Thinking of hitting Amazon with 1000 concurrent users. For achieving the scenario, you cannot purchase 1000 machines to achieve the behavior. JMeter allows you to hit the Amazons server with 1000 requests concurrently. JMeter simulated real-time user’s behavior intelligently. JMeter sends requests to the target server and then retrieves the statistical information of the server. With this information, it generates test reports in different formats.
Some benefits which you gain via JMeter is a User-friendly GUI, Graphical Test Results, easy installation, and platform independence. It has an amazing record and playback feature which makes it very easy to learn even for the novice. Also, its script test can be integrated with Selenium tests and beach shells for more robust automated testing. Through the Jmeter tutorial, we are trying to et up a tutorial for people to learn about this magnificent tool.

Step-by-step Jmeter tutorial

How to Download and Install Apache JMeter
JMeter is a java application and it needs Java in the machine so that it can run seamlessly. JMeter can be installed in Windows, Linux, Ubuntu, and Mac operating systems. Before installing JMeter, make sure that you have Java installed in your machine. You can check by hitting the command in your terminal. java -version
If java version is highlighted then java is installed in your system and if nothing appears then install Java by clicking here.

Now it is the time to download JMeter. Download the latest version by clicking here. Download the binary file shown below.

2. The installation of JMeter is very easy. The download binary file must be unzipped into the folder where you want to download JMeter. The unzipped folder would like just as below snapshot.

3. Run JMeter in GUI mode by clicking on the bin folder and then jmeter.bat file.

4. After clicking, JMeter will open just as below.

More on Thread Group, Samplers, Listeners and Configuration of JMeter

Thread Group is basically the application of multiple threads to AUT. Each thread represents one user who is accessing the application. With the help of the thread group, you can apply a number of threads which is defined by you.

Samplers allow JMeter to support testing of different protocols such as HTTP, FTP, JDBC, and others.

FTP Request: If you want to do performance testing for the FTP server then you can use the config element of the FTP request. You can send a download a file or upload a file request to the FTP server. You need to add parameters to the sampler such as server name, remote file name (to be downloaded or uploaded), port number, username, and password.

HTTP request

With this help of the HTTP request sampler, you can request an HTTP request to the server. With the help of this request, you can retrieve HTML files and images from the server.

JDBC request

With this help of a JDBC request sampler, you can perform database performance testing. You will be able to send a JDBC request to the server. You should be able to add the SQL query in the query tag.

SMTP Server

If you want to test the mail server then you must use the SMTP server sampler. With this protocol, we can send emails.

CSV Data set Config

If you want to test the website with different users who are having different credentials, you must take the help of CSV data set the config to pass the credentials. You can store the credentials in the text file. It will read lines from the file using a delimiter.
You must pass the data in a text file the same as the below snapshot.

HTTP Cookie Manager

When you log in to some website then your browser stores cookie so that you do not have to login again and again. Similarly, an HTTP cookie manager also does the same task for you. If the website is returning cookie in response, then it will save a cookie for you to maintain a session. You can add an HTTP cookie manager in your test plan with the help of the config element. When you will record sessions using Blaze meter, it will automatically record cookies in the HTTP cookie manager.

Listeners

Listeners listen to the results fetched by the JMeter and let you analyze the results with the help of visual reports.

View Results Tree: You get to see all the user requests in HTML format using view results listener.

Aggregate Reports

With the help of aggregate reports, you can get total samples, average, median, minimum, maximum, and throughput.

Jmeter Timers

Once you start sending requests to your AUT, you should have timers between each request so that it can simulate real-time behavior and the server does not get confused with so many requests hitting the server. Let us see the different kinds of timers which we can integrate to simulate real-time behavior.

Constant Timer

It delays each request by the same amount of time.

Gaussian Random Timer

It delays each request by any random amount of time. You can define the deviation around which the delays would be adjusted. Also, offset can be added with the gaussian distribution of deviation value and then the total delay time can be calculated.

Uniform Random Timer

It also delays each request by a random amount of time. You can define the random delay maximum time and the offset value which will be added to the random value.

Bean shell, BSF and JSR223 timers

Bean shell timers introduce a delay time between each request using bean shell scripting. BSF timer is used to add a delay time between each request using BSF scripting language. Similarly, JSR223 adds a time delay using the JSR223 scripting language.
The most used timers are constant and gaussian timers.
Assertions in JMeter
Assertions are very useful in any kind of testing as verification and validation are the heart of testing. You must compare the results with the expected results to know if we are getting the correct response or not. Let us have a look at the most common types of assertions.

Response assertion

It allows you to check the response against pattern strings. Take an example of Amazon.com. If you hit the server with some product then the response list should contain the product mentioned in the search list given in the request payload.
You can choose text response and add the test which you want to validate. I have added the text in patterns to test.

Also, we can validate the status code with the response assertion Select the field to test as response code and mention the code in the patterns to test.

Duration Assertion

It tests that the server’s response is received time limits. If it is taking more than the time mentioned, then the assertion will be failed.

Size Assertion

It checks the response has the expected number of bytes contained in it. If it is above the defined limit, then assertion will be failed. In the below snapshot, if the response has equal or less than 5000 bytes then the assertion will be passed.

XML and HTML Assertion

XML assertion verifies that the response data has correct XML syntax while HTML assertion verifies that the HTML syntax of response is correct.
Controllers in JMeter
Controllers are used in JMeter to handle requests in an organized manner. There are different kinds of controllers that can be integrated with the JMeter Test Plan. These controllers let you handle the order of requests to be sent to the server. Let us have a look at different kinds of controllers.

Recording Controller

JMeter will record your testing steps but for storing them in a container you require a recording controller.

Simple Controller

Simpler Controller is just a container to store your requests. You can give a meaningful name to the controller. In this way, if you want to duplicate the requests, you can simply add the simple controller without again and again adding so many requests. It is just for clubbing requests and in the view, results graph you will not see any controller name.

Loop Controller

It allows the requests to run a specified number of times or forever if the number has not been defined.

Transaction Controller

The transaction controller is similar to the simple controller which records the overall time for the requests to finish. It has an additional benefit over simple controller as you will be able to see the controller name which has the clubbed requests instead of individual requests name in view results graph.

Module Controller

It is based on the idea of modularity which says that a set of requests can be clubbed in a simple or transaction controller. A module controller can be used to add any set of requests by selecting the controller. Suppose if you have 3 simple controllers named login, search and logout, then with the module container you will be able to select which you want to simulate again so that you don’t have to add the same requests again and again.

Interleave Controller

This controller pickups one sampler per iteration and it is executed from top to bottom. In the below snapshot, we are having one interleave controller having 3 samplers names News Page and FAQ Page and Gump Page. It is running with 2 threads and a loop count of 5. So, a total of 10 requests will be executed per thread.

Runtime Controller

This controller controls the execution of its samplers for the given time. If you specify the run time as 10 seconds, then JMeter will run your tests for 10 seconds.

Random Controller

It is the same as the Interleave controller but instead of running from top to bottom, the random controller picks any requests randomly.

If Controller

It runs the requests only when a set of conditions is fulfilled.

Processor in JMeter
Processors are used for modifying the samplers. There are two types of processors.

Pre-processor are the processors which are applied before sampler requests. If you want JMeter to check all the links on the page and then retrieve the HTML. You can add HTML link parser which will parse links before a request is made to the server.
Post-Processor: If the request is made to the server and is the requests send you an error then the post-processor should stop the further execution.

In the above snapshot, if you choose Stop Test Now. This will stop the test if there will be any error in the response.
There is one more post-processor named debug processor which tracks the values of variables that are in the requests.

Jmeter Distributed (Remote) Testing
It is used to do testing on multiple systems. Applying all the load on a single server is not appropriate and can bring unexpected results. It is good to perform distributed testing with master-slave architecture.         There will be one master who will be driving various clients which will be again JMeter servers which will be putting load to the application under test. The firewall should be switched off in all the machines as it can block the traffic. All machines should share the sub-network and the JMeter version should be kept the same in all the machines to avoid any kind of complexities.

Steps to setup master-slave architecture (Jmeter tutorial bonus)
1.       Go to the slave server and then go to the bin directory where JMeter is downloaded. You must then execute a file named JMeter-server.bat. Suppose the slave machine has IP address 120.178.0.9.
2.       Now, go to the master machine and go to the bin directory. There, you have to edit JMeter.properties file. You must add the IP of the slave machine in front of remote_hosts.
3.       Now for running the tests, you must go to the GUI of JMeter. Select the Run section on the menu bar of JMeter and then select a remote start and then the IP address of the slave machine.

Detailed Steps to Use JMeter for Performance & Load Testing (Jmeter tutorial exclusive)
1.       Start JMeter.
2.       Add the BlazeMeter extension to the google chrome browser. Now hit the URL on the google chrome browser and record the flow with BlazeMeter. Once the steps have been captured then you can download the file from BlazeMeter in JMX extension.
3.       You can then open the JMX file in your JMeter. It will appear as below.

4. Now, you must add a number of threads, ramp-up periods, and loop count. Number of Threads is the total number of users accessing the website. The number of times per thread will execute. Ramp-up period is the delay that should be applied before starting the next user. Suppose if you have 1000 users and a ramp period of 1000 seconds then delay between every user request will be 1000/1000 = 1 second.

5. Now, add the listeners to view the graphical results. Let us add the most used listeners such as View Results and Assertions Results.

6. You can also name the requests in different transaction controllers such as login can go to login controller, authenticate, and secure to security controller and logout to sign off the controller. If you want to execute extensive tests, then these controllers will help you running many requests.
7. Add Post-processor which would stop the tests in case you get any errors in the response.

8. Add Constant timer with a time period of 300 ms between each user request.

9. For each request, you can add assertions to validate that if the requests are giving proper response. Different Response assertions can be used to validate the status code as 200 and to validate the test in the output response. You can also add duration assertion to check if the requests are completed in a particular amount of time. Size assertion can be used to check the response in bytes.

10. Now, run the tests using the green run button on top. Now it’s time to analyze view results and assertion results.

You have to analyze the throughput and deviation. Throughput is the server’s ability to handle a number of requests per minute. The higher the throughput the higher is the capacity of the server to handle user requests. The deviation is the second parameter which is of utmost importance in this graph to be analyzed. It means the variation from the average. Throughput should be higher, and deviation should be least. These parameters, you will be getting from the client which you have to validate and send a report to the client with these graphs.
Also, you must remember in this Jmeter tutorial, is the Assertion report.
You will see the different assertions been passed and failed in this tree so that you can know which ones are failing.
One more important listener is the View Results Tree listener. You will be seeing which requests got passed and which ones got failed. The ones which are in green color are passed and the ones which are in red color are failed.
The last important listener which you can add is the Summary report which will let you know total samples, average, Min, Max, Error %, Deviation, and Throughput. This report is of the utmost importance to stakeholders. Let us see how it looks.
Conclusion for Jmeter Tutorial
That sums Use JMeter tutorial to use performance and load testing so that your application is robust and can sand load without giving unexpected results. Use the wonderful elements of JMeter to share excellent reports with the stakeholders.
