Writing unit tests in Java
Testing is a crucial best practice when developing software. Unit testing is one of the numerous strategies we can use to ensure our code is functional and optimal. As developers, we can code unit tests to check individual components (units) of the application code, such as a specific method. The idea is to write one or more unit tests for each code section and run them every time a change is made to catch defects as soon as they are introduced into the codebase.
