17. What Is Negative Testing?

Tip 1: Show that you are aware of the knowledge required for the job.

Tip 1: Show that you are aware of the knowledge required for the job.

Tip 2: The interviewer wants to know that you understand the role.

19. What Is Validation and Verification?

Tip 1: Show that you are aware of the knowledge required for the job.

Tip 2: The interviewer wants to know that you understand the role.

Answer: Validation is evaluating the final product to check if the software meets all the business needs. The test execution that we do in our daily life is the validation activity that includes smoke testing, regression testing, functional testing, etc. The verification is evaluating the intermediary work products of the software development lifecycle to determine if we are on the right track to creating the final product.

20. What Is the Difference Between Load and Stress Testing?

Tip 1: Show that you are aware of the knowledge required for the job.

Tip 2: The interviewer wants to know that you understand the role.

Answer: Stress testing validates the behavior of the product or system when it is executed under stress. We reduce the resources while also checking the behavior of the entire system. We initially understand the upper limit of the product and then reduce the resources and go for checking the system behavior. In contrast, load testing is the validation of product or system behavior in the expected load. This load may be of the concurrent user or the resources that are assessing the system simultaneously.
