JUnit
What is JUnit?
JUnit is a widely used open-source automated testing framework for Java that allows developers to write and run repeatable automated tests. It supports unit testing, enabling developers to validate individual components of an application and ensure code correctness through assertions and test annotations.
Test automation with JUnit is used throughout the software development lifecycle for:
Unit testing: Validating that individual units (e.g., functions, classes) work as intended.
Regression testing: Ensuring that new code changes do not break existing functionality.
Test-driven development (TDD): Writing tests before implementation to guide design and development.
Continuous integration (CI): Automatically executing tests during builds to maintain code quality.
