What will I learn?
The Java Testing Course gives you a fast, practical path to writing reliable tests with JUnit 5, Mockito, and AssertJ. You will design a small domain model, create unit and integration tests, manage test data, and enforce invariants like non-negative availableCopies. Learn clean test structure, coverage goals, naming conventions, and repository hygiene so your Java projects stay maintainable, documented, and easy to run.
