What is Coveralls?

Editorial review
Coveralls helps development teams ensure code quality by providing comprehensive test coverage analysis. It integrates with Continuous Integration (CI) servers to sift through coverage data, identify untested areas, and track changes over time. By visualizing coverage down to the line level, it empowers developers to eliminate technical debt and develop with confidence. This tool is designed for software development teams, individual developers, and organizations that prioritize code quality and maintainability. It's particularly useful for projects using CI/CD pipelines, as it automates the process of tracking coverage and provides insights directly within development workflows, such as pull requests. Coveralls supports a wide range of programming languages and integrates seamlessly with popular version control systems like GitHub, Bitbucket, and GitLab. Key benefits include gaining deep insight into testing suite health, discovering trends in code coverage over the entire development cycle, and preventing bugs by identifying untested code before it becomes a problem. It also allows teams to enforce coverage criteria for merges and broadcast project health with customizable badges.
