What testing patterns does this skill use?

The skill utilizes the Arrange-Act-Assert (AAA) pattern for unit testing and Given-When-Then for Behavior-Driven Development (BDD) scenarios.

Does this skill identify edge cases automatically?

Yes, it specifically considers boundary values, null inputs, network failures, and concurrent access issues to ensure comprehensive coverage.

Is it compatible with specific programming languages?

While the principles are universal, the skill provides language-specific imports and setup suggestions for most modern development environments.

Can it help with external dependencies like databases?

Yes, it includes a sophisticated mocking strategy to isolate external services, APIs, and databases during the testing process.

What is the recommended test distribution?

The skill follows the Testing Pyramid guideline: approximately 70% Unit tests, 20% Integration tests, and 10% End-to-End (E2E) tests.
