spring-boot-test-patterns

This skill provides comprehensive guidance for writing robust test suites for Spring Boot applications. It covers unit testing with Mockito, integration testing with Testcontainers, performance-optimized slice testing patterns, and best practices for maintaining fast feedback loops.

Spring Boot testing follows a layered approach with distinct test types:

Prefer @ServiceConnection over manual @DynamicPropertySource for cleaner code:

Provides comprehensive testing patterns for Spring Boot applications including unit, integration, slice, and container-based testing with JUnit 5, Mockito, Testcontainers, and performance optimization.
