OyenCov is a specialized test coverage service designed exclusively for Rails applications, offering a usage-weighted approach to testing. Unlike traditional test coverage tools that treat all code equally, OyenCov focuses on real-world usage patterns, ensuring that the most critical parts of your application are thoroughly tested. By analyzing how users interact with your app, it helps you prioritize testing efforts on the code that matters most. This approach improves efficiency, saves time, and ensures higher code quality by covering the areas that are actually being used.
