Slice tests in Spring Boot isolate specific application layers like web controllers or data repositories without loading the full context. This Skill provides patterns to optimize execution speed by targeting only the necessary components for each test.

Unit tests for Spring Boot services with Mockito and JUnit 5 mock external dependencies to verify business logic in isolation. This Skill offers patterns to generate basic mocked unit tests and establish robust test suites.

Optimizing Spring Boot test execution speed relies on context caching and container reuse to minimize startup overhead. This Skill provides performance optimization patterns to speed up test execution across unit and integration tests.

Yes, testing reactive Spring Boot applications is supported through detailed examples and specific testing strategies. This Skill provides comprehensive patterns covering reactive testing alongside standard unit and integration tests.

Use slice tests instead of full integration tests in Spring Boot when verifying isolated application layers without the startup overhead. This Skill clarifies when to apply slice, unit, or container-based integration testing strategies.
