Learning Outcomes
At the end of this program, you will be able to:
Conditional and Parameterized Testing
Create flexible tests that run under specific conditions or validate multiple data sets using a single test method, improving coverage while reducing duplication.
Mocking and Stubbing with Mockito
Use Mockito to isolate code by mocking dependencies, creating stubs and spies, verifying interactions, and testing components in a controlled environment.
Testing Advanced Java Applications
Learn techniques for testing I/O operations, DAOs, servlets, and multi-threaded applications, while improving reliability and reducing flaky tests.
Test-Driven Development (TDD)
Apply the Red-Green-Refactor cycle to write cleaner, more maintainable code, improve software quality, and prevent regressions through test-first development.
