10 . What are the different types of test levels?

Test levels are classified into four main categories –

  • Integration testing
  • Acceptance testing
  • System testing
  • Unit/component/module/program testing

11. What do you understand by black box testing and what about their techniques?=

It is a kind of software testing meant for testing different software without the information of the code’s internal structure or program. This testing is performed to check on the functionality of applications. Some of the different black box techniques are – 

  • Cause-effect graphing
  • Equivalence partitioning
  • Boundary value analysis

12. Highlight the difference between validation and verification

Validation is defined as a method of evaluating software after the completion of the development phase. This helps in deciding whether the final product meets the expected requirements or not. 

Verification is a procedure used for evaluation purposes of software during the development phase.

  • Generating a profile for risk.
  • Using the resources of test risk.

7. What are the reasons behind a project to get failed?

Some of the common causes of a project failure are –

  • Lack of human resources.
  • Insufficient budget.
  • Time restriction
  • The testing environment is not set appropriately.

8. What do you understand by test management review and what is its significance?

Also known as Software Quality Assurance, management review primarily emphasizes software procedure in spite of final products. It is available as a set of test activities that are specifically designed to ensure that the standard procedures are properly followed by a project manager.

9. Enlighten about the difference between traceability matrix and test matrix

The traceability matrix is about the mapping between customer needs and test cases. Whereas, a test matrix is highly used for capturing the plan, time, quality, effort, and resources needed to detain all steps of software testing.

10. What do you mean by latent defect?

A latent defect is present in the system as an existing defect that is not responsible for any kind of failure. It seems like the actual set of conditions has never been met before.

11. How can you explain the working of the test coverage tool?

The test coverage tool is implemented parallel to the testing of the actual product. This tool is mainly used for keeping a check on executed statements of source code. Once the final testing procedure gets completed, it is easy to get a whole report of pending statements as well as a coverage percentage.

12. What are the differences between testing tools and testing techniques?
