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.
