Skillshub spring-boot-testing

Standards for unit, integration, and slice testing in Spring Boot 3. Use when writing unit tests, integration tests, or slice tests for Spring Boot 3 applications. (triggers: **/*Test.java, webmvctest, datajpatest, testcontainers, assertj)

Spring Boot Testing Standards

Priority: P0

Implementation Guidelines

TDD Workflow

Red: Write a failing test (e.g.,
```
returns 404
```
).
Green: Implement minimal code to pass.
Refactor: Clean up while keeping tests green.
Coverage: Verify with JaCoCo.

Best Practices

Real Infrastructure: Use Testcontainers for DB/Queues. See Integration Template. Avoid H2/Embedded.
Assertions: Use AssertJ (
```
assertThat
```
) over JUnit assertions.
Isolation: Use
```
@MockBean
```
for downstream dependencies in Slice 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.
