Suggested path
Topics follow a teaching order. Each answer ends with a clear Next question control so you can move forward without hunting the list.
JUnit testing (fresher level) introduces automated testing. This module is an elevation arc: it opens with why unit testing (the motivation — defects, design, confidence), then JUnit 5 basics (the architecture), then annotations and lifecycle (the test hooks). Assertions and test naming follow at the mechanics tier, then parameterized tests (the data-driven pattern). Testing best practices close the module.
