Provides patterns for unit testing service layer with Mockito. Creates isolated tests that mock repository calls, verify method invocations, test exception scenarios, and stub external API responses. Use when testing service behaviors and business logic without database or external services.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Unit Testing Service Layer with Mockito ## Overview Provides patterns for unit testing `@Service` classes using Mockito. Mocks repository calls, verifies method invocations, tests exception scenarios, and stubs external API responses. Enables fast, isolated tests without Spring container or database. ## When to Use - Testing business logic in `@Service` classes - Mocking repository and external client dependencies - Verifying service interactions with mocked collaborators - Testing error handling and edge cases in services - Writing fast, isolated unit tests (no database, no API calls) ## Instructions Follow this workflow to test service layer with Mockito, including validation checkpoints: ### 1. Setup Test Class Use `@ExtendWith(MockitoExtension.class)` to enable Mockito annotations. ### 2. Declare Mocks with `@Mock` and `@InjectMocks` Use `@Mock` for dependencies (repositories, clients) and `@InjectMocks` for the service under test. ### 3. Arrange-Act-Assert with Validation **Arrange**: Create test data and configure mock return values using `when().thenReturn()`. **Act**: Execute the service method being tested. **Assert**: …

How to install
mdr add giuseppe-trisciuoglio/developer-kit/unit-test-service-layer@sha256:d3fc4cce9bff63d8The line at the top of this page pins the label git:20260324.a02e282, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
