spring-boot-testing
Write unit, integration, and slice tests for Spring Boot 3 applications. Use when writing unit tests, integration tests, or slice tests for Spring Boot 3 applications. (triggers: **/*Test.java, webmvctest, datajpatest, testcontainers, assertj)
Best use case
spring-boot-testing is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Write unit, integration, and slice tests for Spring Boot 3 applications. Use when writing unit tests, integration tests, or slice tests for Spring Boot 3 applications. (triggers: **/*Test.java, webmvctest, datajpatest, testcontainers, assertj)
Teams using spring-boot-testing should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Spring Boot Testing Standards ## **Priority: P0** ## Follow TDD Workflow 1. **Red**: Write a failing test (e.g., `returns 404`). 2. **Green**: Implement minimal code to pass. 3. **Refactor**: Clean up while keeping tests green. 4. **Coverage**: Verify with JaCoCo. ## Write Slice and Integration Tests - **Real Infrastructure**: Use **Testcontainers** for DB/Queues. Avoid H2/Embedded. - **Assertions**: Use **AssertJ** (`assertThat`) over JUnit assertions. - **Isolation**: Use `@MockBean` for downstream dependencies in Slice Tests. See [implementation examples](references/implementation.md) for WebMvcTest slice tests and Testcontainers integration tests. ## Anti-Patterns - **No Dirty Contexts**: Avoid @MockBean in base classes; it reloads context per test. - **No network I/O in tests**: Mock external calls with WireMock. - **No System.out in tests**: Use AssertJ assertions instead. ## References - [Implementation Examples](references/implementation.md)
