How does it handle external API calls during testing?

The skill enforces the use of WebMock for all HTTP requests, preventing live network calls and ensuring that tests are fast and deterministic.

Why are system tests discouraged in this skill?

To maintain high performance and lower complexity, this skill prioritizes integration tests over Capybara-based system tests while still providing full-stack coverage.

What is the Red-Green-Refactor cycle?

It is the core TDD process: first write a failing test (Red), then write the minimal code to pass (Green), and finally improve the code structure (Refactor).

Does this skill support RSpec?

No, this skill is strictly opinionated toward Minitest to ensure the test suite remains fast, simple, and aligned with Rails' built-in defaults.

How does it manage test data?

This skill follows standard Rails conventions by using fixtures located in the test/fixtures directory instead of third-party factory libraries.

Seguridad y Pruebas

Implements rigorous Test-Driven Development (TDD) using Minitest and Rails-native patterns to ensure high-quality, maintainable codebases.

Acerca de

This skill provides a comprehensive framework for testing Ruby on Rails applications using an opinionated, Minitest-first approach. It strictly enforces the Red-Green-Refactor cycle, ensuring that no implementation code is written without a preceding failing test. By focusing on Rails-native tools like fixtures and integration tests while explicitly forbidding RSpec and heavy system tests, it facilitates a fast, lightweight, and reliable testing environment. It includes specialized patterns for model validations, associations, scopes, and external dependency mocking via WebMock to maintain deterministic test results.
