Software Testing - Interview Questions and Answers

Here you will get all the possible answers of Software Testing Job Interview Questions and Answers

1. Are there more defects in the design phase or in the coding phase?

The design phase is more error prone than the execution phase. One of the most frequent defects which occur during design is that the product does not cover the complete requirements of the customer. Second is wrong or bad architecture and technical decisions make the next phase, execution, more prone to defects. Because the design phase drives the execution phase it's the most critical phase to test. The testing of the design phase can be done by good review. On average, 60% of defects occur during design and 40% during the execution phase.

2. Can you explain boundary value analysis?

In equivalence partitioning we identify inputs which are treated by the system in the same way and produce the same results. You can see from the following figure applications TC1 and TC2 give the same results (i.e., TC3 and TC4 both give the same result, Result2). In short, we have two redundant test cases. By applying equivalence partitioning we minimize the redundant test cases.

So apply the test below to see if it forms an equivalence class or not:

• All the test cases should test the same thing.
• They should produce the same results.
• If one test case catches a bug, then the other should also catch it.
• If one of them does not catch the defect, then the other should not catch it.

3. Can you explain requirement trace-ability and its importance?
