Software Testing Interview Questions and Answers for Experienced

These questions are suitable for those professionals having two to three years of experience in the testing field. These questions will help you to explore more career options and increase your salary package too.

Q1). How can you define the relationship between test phases and environment reality?

When test phases are in progress stage, environment reality becomes more significant here. For unit testing, the environment is partly real. At the same time, for acceptance testing, the environment should be 100 percent real.

Q2). Should testing be done during execution or after the execution?

Well, it is great to perform testing at earlier phases. Earlier you catch the bug; there are better chances of resolving errors without issues. For example, if you catch a defect in the maintenance phase, it is ten times costlier to fix than the execution phase.

Q3). Take an example that defects that can be removed at the initial stage were removed in a later stage. So, how will it affect the costs?

It is obvious that if a defect is found at an earlier stage, then it should be removed at the same stage. In case, it is resolved in a later stage, then costs may increase up to 20 times that depends on when you fix it. The following figure will give you a perfect idea of cost evaluation at later stages. This is one of the frequent asked software tester interview questions and answers. 

If a defect is identified and fixed during requirements and design stage, then it is quite easy to afford. On the other hand, if the same defect is fixed during the maintenance phase, it becomes 20 times costlier.

Q4). How will you define the regression and confirmation testing?

Regression testing shows that changes made to the code will not affect the other functionalities of a software application. If a software product fails due to some errors, then a new version is launched where previous bugs were fixed gracefully, it is called the confirmation testing or retesting.

Q5). How to estimate the project cost? Tell us based on your past experiences?

This is how you should answer these types of software testing interview questions to be fully prepared for your interview.  

To estimate the project costs, the following facts should be considered by a quality engineer.

• Divide the complete project into small chunks.
• Allocate tasks to different team members.
• Now estimate efforts required to complete each task.
• In the last step, validates should be estimated.

Q6). Do you have any idea of Random testing?

For random testing, data is usually generated randomly with the help of a tool. Here is the diagram to show how random data is sent to the system.

Random data is collected with the help of a tool, or you can use any other mechanism too. The system is tested with randomly generated, and results are observed accordingly.
