What problem does it solve?
This skill helps Java developers adopt test-first workflows by guiding the creation of focused JUnit 5 tests before production code, following the TDD red-green-refactor cycle.
Core Features & Use Cases
- Write the smallest failing JUnit 5 test that captures the requested behavior.
- Choose the correct test scope (unit, integration, or contract) and keep tests focused.
- Configure Maven Surefire or Gradle test execution and keep build-tool wiring separate from test logic.
- Apply Mockito for isolated boundaries and Awaitility for asynchronous behavior when appropriate.
- Follow conventions for test naming, nested contexts, and maintainable test structure.
Quick Start
Start by writing the smallest failing JUnit 5 test that captures the requested behavior, then implement the production code and wire the build tool.
