May 11, 2024 · Unit Testing is a methodology of testing source code for its fitment of use in production. We start out writing unit tests by creating various test cases to verify the behaviors of an individual unit of source code.

JUnit is Java's unit testing framework. We'll guide you on using this framework by introducing the idea of "test-driven development" i.e set up test data for a piece of code and then implement it. We'll take you through the test-driven design recipe using a simple example of implementing an add method in a class Calculator.java.
