How do I start tracking coverage with this skill?

The skill provides automated setup commands to add the necessary gems, configure your .simplecov file, and ensure the coverage engine starts correctly at the top of your test helper.

Does it support branch coverage?

Yes, it configures SimpleCov to track branch coverage (available in Ruby 2.5+), helping you identify untested paths in complex conditional logic.

How does it help with CI/CD pipelines?

It includes configuration examples for GitHub Actions and terminal scripts that enforce coverage thresholds, ensuring that pull requests cannot be merged if they drop below your defined standards.

Can I use this with RSpec and Minitest?

Absolutely. This skill includes implementation patterns for Minitest, RSpec, Cucumber, and even parallel testing suites.

Security & Testing

Analyzes and improves Ruby and Rails test coverage using SimpleCov and automated quality metrics.

About

The SimpleCov Test Coverage Agent provides a robust framework for maintaining high-quality codebases in Ruby and Rails environments. By leveraging SimpleCov and SimpleCov Console, it offers automated analysis of test suites to identify coverage gaps, enforce quality thresholds, and suggest targeted improvements. The skill goes beyond basic metrics by integrating branch coverage tracking and RubyCritic analysis, allowing developers to prioritize refactoring for complex, high-churn code that lacks sufficient protection. Whether you're setting up a new project or auditing a legacy application, this skill ensures your testing efforts are efficient and comprehensive.
