Can it help with browser-based testing?

Absolutely. It provides detailed patterns for System Tests using Capybara to simulate real user interactions, button clicks, and form submissions.

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

Yes, the skill is specifically designed to facilitate the 'Red-Green-Refactor' cycle, helping you write failing tests first and then implementing the minimal code to pass.

Why use Minitest instead of RSpec with this skill?

Minitest is the Rails default, offering faster performance and zero configuration. This skill leverages those strengths to keep your test suite lean and efficient as per Rails philosophy.

Can it debug existing failing tests?

Yes, the skill can analyze failure messages and stack traces to suggest specific code fixes or test adjustments to resolve regressions.

How does it handle test data and state?

The skill specializes in Rails fixtures (YAML), including handling associations, polymorphic relationships, and using ERB for dynamic data generation.
