Q2. Explain about test techniques available in the market in detail and give some examples of the exact purpose of using the same?

Answer:
The test technique is designed mainly to resolve the two purposes, one is defect identification and another one is concentrating on reducing design test cases.

Available varieties of test techniques are:

Partitioning in equivalent approach.
Analysis value of boundary on allowed data.
Testing on a specifical transition of state.
Testing pairwise.

Let us move to the next Testing Interview Questions.

Q3. Is testing really necessary for any kind of application? If yes, then explain why we could not able to avoid testing?

Answer:
Testing is obviously necessary for any kind of software products. It is actually ensuring application deliverable in end-user perspective. It used mainly to identifying application defects which anytime harmful for that specific software. So without testing releasing any software will be a big risk and that can cause serious issues.
