How does it handle MockK limitations with value classes?

The skill includes specialized logic to detect @JvmInline value classes and uses real instances instead of mocks to prevent common unbox-impl errors during testing.

Can I customize the testing libraries or naming conventions?

Yes, the skill reads from a project-config.md file to apply your specific preferences for assertion libraries (like Google Truth) and naming styles (English or Japanese).

Does it support testing Android Framework classes like Intent or Uri?

It provides best-practice patterns for framework classes, suggesting mockkStatic for Uri or Robolectric configurations to avoid 'Method not mocked' errors in pure JUnit tests.

Does it handle Kotlin Coroutines automatically?

Yes, it intelligently determines whether to use runTest or testScope.runTest based on the class type and its asynchronous dependencies.

What architectures does this skill support?

It primarily supports MVI (Model-View-Intent) and Clean Architecture patterns, including specific templates for Reducers, StateManagers, Presenters, UseCases, and Repositories.

Mobile Development

Automatically generates standardized, architecture-aware Android unit tests using MockK and Coroutines based on your implementation code.

The Android Test Generator is a specialized Claude Code skill designed to accelerate Android development by automating the creation of high-quality unit tests. It intelligently analyzes implementation code to identify class roles—such as Reducers, StateManagers, ViewModels, or UseCases—and applies corresponding templates following industry best practices. By integrating project-specific configurations, it ensures consistent testing patterns across Domain, Data, and UI layers while handling complex scenarios like Kotlin value classes, Coroutine dispatchers, and Android Framework dependencies.
