- Mention the key challenges of Software Testing.
Key challenges may include:
- Testing phase under a time constraint
- Regression Testing
- The application must be stable to run tests
- Lack of tools, resources, and training for the testers
- Mention different types of testing methods.
There are 3 basic methods-
Black-Box Testing: No in-depth knowledge of internal paths, structures, or implementation is required.
White-Box Testing: Core and in-depth knowledge of internal paths, structures, and implementation are required.
, and Grey-Box Testing: Limited knowledge would suffice to detect and debug the software.
- Difference between functional and non-functional testing.
Functional testing is done before non-functional based on the client’s requirements and describes what a product does. Non-functional testing is based on the client’s expectations and tells how the product works.
- Mention the benefits of Automated Testing.
Cost-saving, fast Development, and Delivery of products, higher productivity, effective and efficient use of resources, support repeated test cases execution, improves accuracy.
- What is usability testing?
It is a type of testing methodology where a user is asked to use the product to check whether the software is easy to use, its task loading time, and to understand the customer’s perception.
- Describe how Testing is affected by Object-Oriented Programming.
Makes it easier for testers to trace the requirements from code to internal paths to functional designs.

- Specific Type test plans– it is designed for non-functional testing like security testing, loading testing, etc.
- Master test plans– It’s a complete test approach
- What is the difference between Verification and Validation in Software Testing?
Verification– It is a static testing process to check if the application achieves its goals without any bugs
Validation– It is a dynamic testing process to determine whether the product we are developing is the right product and meets the client’s requirements.

Smoke test, Regression Test, Data-driven, Non-functional, and Complex Calculation test cases.
- Difference between Regression and Confirmation testing.
Regression Testing– To ensure that a change in recent code doesn’t affect existing characteristics.
Confirmation Testing– Or re-testing is a process of introducing a new version of software whose defect is fixed.
- What is BVA?
Boundary Value Analysis is a black-box testing technique used to check whether there are any bugs at the edge of the input domain.

- Compare Agile Testing with Traditional testing?
Traditional Testing follows a phased testing approach where unit testing is performed for each module without any tools. It is time-consuming and more costly. Agile Testing follows an iterative approach along with an adaptive model where the bugs are fixed during testing using automated tools and then released.
- What is the command to click on hyperlink using linkText()?
The command is as follows-
driver.findElement(By.linkText(& ldquo; Google& rdquo)).click();
- What is Defect cascading?
When a defect goes unnoticed while performing tests it invokes other defects due to which multiple defects arise in the later stages.
- What method to use when there is no frame id and frame name?
If such the case is, we can approach fame by index. The syntax would go like this-
driver.switchTo().frame(int arg0);
- Mention a difference between Beta and Pilot Testing.
Beta Testing is User Acceptance Testing which is performed in the development environment after the product launch to minimize the failure risks. Pilot testing is done before launching a product in a real environment.
- Describe Configuration Management.
It determines the tools, including source code, test scripts, hardware, third-party software, and development and testing documentation to establish the consistency of a product.
- What would be your strategy if you find that the testers in your company are performing deliverables even after a potential defect has been detected?
The acceptance pattern should be strict, test cases must be revised and added more to check the ineffectiveness, and the show-stopper bar should be improved as compromising the company’s quality is not acceptable.
- What is Load Testing on websites?
The QA engineers need to multiply the number of responses a user is getting when sending a request to that site’s server to simulate different traffic loads.
- Describe TestNG.
It is an advanced testing framework designed with an inbuilt exception of handling mechanism which helps the program to run without terminating suddenly.
- How will you skip a method or a code block in TestNG?
We can set the ‘enabled’ parameter in test observation to false using the below format-
@Test(enabled=false)
- How would you find out the quality of the test execution?
There are two ways to determine it-
- Defect Rejection ratio: (No. of defects rejected/total no. of defects raised)*100
- Defect Leakage ratio: (No.of defects missed/total defects of software)*100
- Acceptance plan is prepared on what basis?
Requirement documents, input from the customer, and project planning determine the acceptance plan.
- Describe XPath.
Also known as XML Path is a language to query XML docs. One can easily write a query in XPath script to locate elements in a webpage. It also generates reliable locators.
- What is Absolute Xpath?
It is a better and more direct way to find the element but if you make any changes in the path of the element then that XPath gets failed. For instance, /html/body/div[1]/section/div[1]/div
- What is Relative XPath?
The path starts from the middle of the HTML DOM pattern and begins with the forward double slash (//) which signifies that you can search the element anywhere on the webpage.
- How will you handle the conflicts between teams?
Since the team members are from diverse backgrounds and different working styles, the key step as a Team Manager would be open communication for all to understand better and work together which also minimizes the frustration within the team.
