• What is the purpose of unit testing? Who performs it? How is the test data prepared? • What is the difference between unit testing and integration testing? • What are the objectives of integration testing? • Who is responsible for user acceptance testing (UAT)? What are the primary objectives of UAT? • Who defines the test data for the UAT?

Answers

Purpose of Unit testing:

Unit testing is the initial or first level to test the software.

Test Data

  • Data need to perform testing.
  • Testers don't have exact or actual data to test
  • The test data is to check the probability of error that may occur.
  • There are various tools to generate or create test data
  • Is used to track the actual output vs expected output.

For example:

Consider a login page having username and password. The conditions are

User name should accept only alphabets and numbers and should not allow blank spaces

passwords should be a combination of alphanumeric and symbols and have more than 8 characters.

The test data should be written as cases

case 1: leave the username as blank and enter the password

Expected Result: It should throw an error

Case 2: Enter symbols in a username and enter the password

Expected Result: It should throw an error

Likewise, the cases for all combinations should be tested.

Unit testing is used to

  1. To test the individual module/components/units of software.
  2. Ensure to validate every single unit/module of the software.

Who will perform unit testing?

Usually done by the developer who develops the software.

Integration testing:

The individual module/unit/components of software will be combined together and tested to check whether all the modules are properly integrated and working well.

Unit Testing

Integration Testing

The first phase of testing

The third phase of testing

Done by the developer who develops the software

Done by the tester

Individual components are tested

Individual components are combined and tested

The objective of integration testing

To find the problems or errors raised when individual components are integrated.

User Acceptance Testing:

  1. Usually done by the client or the end-user who is going to use the software.
  2. The final phase of testing
  3. Done usually before introducing the products in the market.

Who will perform UAT?

Client/end-user

Objective of UAT

  1. To check whether the expected output meets the actual output.
  2. To check whether all the features added are necessary

Who defines test data for UAT?

Client

End-user
