## Mockito Annotations
| Annotation | Purpose |
|------------|---------|
| `@Mock` | Create mock object |
| `@InjectMocks` | Inject mocks into class under test |
| `@Spy` | Partial mock - real methods + mock behavior |
| `@Captor` | Capture arguments passed to mock |
| `@MockBean` | Mock bean in Spring context |
## Test Template
```java
@ExtendWith(MockitoExtension.class)
class ServiceTest {
@Mock
private Repository repository;
@InjectMocks
private Service service;
@Test
@DisplayName("Should do something when condition is met")
void shouldDoSomethingWhenConditionIsMet() {
// Given (Arrange)
when(repository.findById(1L)).thenReturn(Optional.of(entity));
// When (Act)
var result = service.doSomething(1L);
// Then (Assert)
assertThat(result).isNotNull();
verify(repository).findById(1L);
}
}
```
## Best Practices
1. **One assertion per test** - Focus on single behavior
2. **Descriptive test names** - Use `@DisplayName`
3. **AAA Pattern** - Arrange, Act, Assert
4. **Test behavior, not implementation**
5. **Fast tests** - Mock external dependencies
6. **Isolated tests** - No shared state
