spring-boot-test-patterns

Comprehensive testing patterns for Spring Boot applications covering unit, slice, integration, and container-based tests. Comprehensive guidance for writing robust test suites for Spring Boot applications using JUnit 5, Mockito, Testcontainers, and performance-optimized slice testing patterns. Spring Boot Test: Testcontainers: Test business logic with mocked dependencies: See unit-testing.md for advanced patterns. Use focused test slices for specific layers: See slice-testing.md for all slice patterns. Test controllers with MockMvc: Configure containers with Spring Boot 3.5+: Apply with @Import(TestContainerConfig.class) on test classes. See testcontainers-setup.md for detailed configuration. Include required testing dependencies: See test-dependencies.md for complete dependency list. Set up GitHub Actions for automated testing: See ci-cd-configuration.md for full CI/CD patterns.
