Unit testing involves individually testing small units or modules of code, such as functions, classes, or programs, to determine if they are fit for use. The goal is to isolate each part of a program and verify that it works as intended, helps reduce defects early in the development process, and improves code design. Unit testing is typically done by developers to test their code meets its design before integration testing.

- 2. UNIT TESTING Unit testing, a testing technique using which individual modules are tested to determine if there are any issues by the developer himself. The main aim is to isolate each unit of the system to identify, analyze and fix the defects.. typically written and run by software developers to ensure that code meets its design and behaves as intended. Its goal is to isolate each part of the program and show that the individual parts are correct.
- 3. Unit Testing Life Cycle
- 4. Unit Testing - Advantages: Reduces Defects in the Newly developed features or reduces bugs when changing the existing functionality. Reduces Cost of Testing as defects are captured in very early phase. Improves design and allows better refactoring of code. Unit Tests, when integrated with build gives the quality of the build as well.
- 5. Unit Testing Techniques Black Box Testing - Using which the user interface, input and output are tested. White Box Testing - used to test each one of those functions behaviour is tested. Gray Box Testing - Used to execute tests, risks and assessment methods.
