| description | Use when you need to write unit tests for Spring Boot applications — including pure unit tests with @ExtendWith(MockitoExtension.class) for @Service/@Component, slice tests with @WebMvcTest and @MockBean for controllers, @JsonTest for JSON serialization. For framework-agnostic Java use @131-java-testing-unit-testing. Part of the skills-for-java project |

Spring Boot Unit Testing with Mockito
Apply Spring Boot unit testing guidelines with Mockito.
What is covered in this Skill?
- Pure unit tests: @ExtendWith(MockitoExtension.class), @Mock, @InjectMocks for @Service/@Component (no Spring context)
- Slice tests: @WebMvcTest, @MockBean for controllers
- @JsonTest for JSON serialization
- @TestConfiguration, @ActiveProfiles for test setup
Scope: Apply recommendations based on the reference rules and good/bad code examples. For integration tests use @322-frameworks-spring-boot-testing-integration-tests.
Constraints
Before applying any test changes, ensure the project compiles. If compilation fails, stop immediately. After applying improvements, run full verification.
- MANDATORY: Run
./mvnw compile or mvn compile before applying any change
- SAFETY: If compilation fails, stop immediately
- VERIFY: Run
./mvnw clean verify or mvn clean verify after applying improvements
- BEFORE APPLYING: Read the reference for detailed rules and good/bad patterns
When to use this skill
- Review Java code for Spring Boot unit tests
- Apply best practices for Spring Boot unit tests in Java code
