25. Unit Testing and Debugging (e.g., JUnit)
The chapter covers essential practices in software development, focusing on unit testing and debugging to ensure code quality and reliability. It introduces JUnit, a significant testing framework in Java, and explains how unit tests are created, their structure, and the importance of Test-Driven Development (TDD). Common debugging techniques and best practices for both testing and debugging are highlighted to aid developers in improving software quality.

What we have learnt
- Unit testing involves testing individual components to ensure their correct functioning.
- JUnit is a popular framework that supports annotations and assertions for efficient unit testing.
- Debugging is a systematic process to identify and fix issues in software.
Key Concepts
- -- Unit Testing
- A software testing method where individual units or components are tested independently to ensure they function as expected.
- -- JUnit
- An open-source framework for writing and running tests in Java, supporting various annotations and assertions.
- -- TestDriven Development (TDD)
- A development approach where tests are written before the code to ensure functionality meets requirements.
- -- Mocking
- A technique in unit testing where dependencies are simulated to isolate the unit being tested.
- -- Code Coverage
- A measure of how much of the code is executed during tests, indicating testing effectiveness.
- -- Debugging
- The systematic process of detecting, analyzing, and fixing bugs or issues in software.
