How does it handle complex dependency injection?

It utilizes Mockito's @InjectMocks to automatically wire mocked dependencies into the service under test, supporting both constructor and field injection.

Can it handle asynchronous or reactive service methods?

Yes, it includes patterns for testing CompletableFuture and other async types common in modern Java and Spring Boot applications.

Does this skill require a running database or external services?

No, this skill focuses on isolated unit testing by mocking all external dependencies, ensuring tests are fast and environment-independent.

Does it support the AssertJ library for assertions?

Yes, the skill encourages and provides patterns for using AssertJ’s fluent API to create readable and maintainable test assertions.

安全与测试

Generates and implements robust Mockito unit tests for Java service layers to validate business logic in isolation.

This skill provides standardized patterns and implementation guides for unit testing Spring Boot @Service classes using the Mockito framework and JUnit 5. It enables developers to rapidly create isolated tests that mock external dependencies like repositories and API clients, allowing for fast execution and deep validation of complex business workflows, error handling scenarios, and asynchronous operations without the overhead of starting a Spring container.
