# Spring Boot Testing This skill provides expert guide for testing Spring Boot 4 applications with modern patterns and best practices. ## Core Principles 1. **Test Pyramid**: Unit (fast) > Slice (focused) > Integration (complete) 2. **Right Tool**: Use the narrowest slice that gives you confidence 3. **AssertJ Style**: Fluent, readable assertions over verbose matchers 4. **Modern APIs**: Prefer MockMvcTester and RestTestClient over legacy alternatives ## Which Test Slice? | Scenario | Annotation | Reference | |----------|------------|-----------| | Controller + HTTP semantics | `@WebMvcTest` | [references/webmvctest.md](references/webmvctest.md) | | Repository + JPA queries | `@DataJpaTest` | [references/datajpatest.md](references/datajpatest.md) | | REST client + external APIs | `@RestClientTest` | [references/restclienttest.md](references/restclienttest.md) | | JSON (de)serialization | `@JsonTest` | [references/test-slices-overview.md](references/test-slices-overview.md) | | Full application | `@SpringBootTest` | [references/test-slices-overview.md](references/test-slices-overview.md) | ## Test Slices Reference - [references/test-slices-overview.md](references/test-slices-overview.md) - Decision matrix and comparison - [references/webmvctest.md](references/webmvctest.md) - Web layer with MockMvc - [references/datajpatest.md](references/datajpatest.md) - Data layer with Testcontainers - [references/restclienttest.md](references/restclienttest.md) - REST client testing...
