TDD guidance for Spring Boot services with 80%+ coverage (unit + integration). New features or endpoints Bug fixes or refactors Adding data access logic or security rules 1) Write tests first (they should fail) 2) Implement minimal code to pass 3) Refactor with tests green 4) Enforce coverage (JaCoCo) Patterns: Arrange-Act-Assert Avoid partial mocks; prefer explicit stubbing Use @ParameterizedTest for variants Use reusable containers for Postgres/Redis to mirror production Wire via @DynamicPropertySource to inject JDBC URLs into Spring context Maven snippet: Prefer AssertJ (assertThat) for readability For JSON responses, use jsonPath For exceptions: assertThatThrownBy(...) Maven: mvn -T 4 test or mvn verify Gradle: ./gradlew test jacocoTestReport Remember: Keep tests fast, isolated, and deterministic. Test behavior, not implementation details.
