Software Testing MCQ With Answers

Software Engineering is a systematic, disciplined, cost-effective technique for software development. In simple terms, it is an engineering approach to developing software.

Software testing is a part of the software development process. Software testing is an activity to detect and identify defects in software. The primary purpose of testing is to release quality products to the client.

Testing in Software Engineering 

  • At different stages of software development, we need to test what we develop.
  • When we develop a unit, we test it when we integrate it with other units.
  • Also, it needs to be tested before giving the software to the customer.
  • In some testing types, we directly deal with the code, which is known as white box testing.
  • In some other cases, we do not have to look at the code and it is known as black-box testing.
  • A mixture of these two is known as gray box testing.

Unit Testing

  • Testing a single unit of the software is known as unit testing.
  • In this testing, we will test an isolated unit of the software, which contains lots of the units.

Integration Testing

  • Here, the testing of a few units of the software is done separately. Now, after testing, those units are integrated.
  • After integrating those units, it is again tested.
  • This is known as integration testing.

Regression Testing

  • Here, a new module is made and it is added to the software.
  • Whenever a new module is added to the software, it is tested to check whether the software is working fine with the change.
  • This is known as regression testing.

System Testing

  • The complete software is ready and working as a system.
  • In this testing, the focus is the entire software. The testing is done based on Evolutionary are input and output.
  • Software compatibility is tested on different kinds of OS.
  • Testing the software comes under the black box testing category.

Stress Testing

  • The software is tested under unfavorable conditions.
  • In this testing, the software is pushed to its maximum limit to check whether any failure occurs under some unfavorable conditions.
