Does this skill support Test-Driven Development (TDD)?

Yes, it includes patterns and best practices for TDD, helping you define expected behavior and edge cases before or alongside implementation.

What testing levels are covered by this skill?

It covers the full spectrum of the testing pyramid: Unit Tests (fast/cheap), Integration Tests (boundary/component), and E2E Tests (critical user flows).

Does it provide guidance on code coverage?

Yes, it suggests targeting over 80% line coverage and 70% branch coverage, with a specific focus on 100% coverage for critical business paths.

How does the skill handle complex data setup?

It promotes the use of the Builder pattern and Test Fixtures to manage complex test data, making test setup clean and reusable.

What is the primary benefit of the Testing skill?

It provides a standardized framework for Claude to write high-quality, maintainable tests using the Testing Pyramid and AAA pattern, ensuring your code is reliable and bug-free.
