We help you deliver code confidently by showing which parts of your code aren’t covered by your test suite.
Eliminate Tech Debt
Maintaining a well-tested codebase is mission-critical, but figuring out where your tests are lacking can be painful. You're already running your tests on a continuous integration server, let it do the heavy lifting. Coveralls works with your CI to sift through coverage data to find gaps you didn't know you had.
Badge your repo
Display your coverage percentage like a badge of honor with our — well — Badges of Honor. Encourage others to join the movement for code coverage!
Increase team awareness
Coveralls believes that developers should always strive to write better code. We've created the leading code coverage SaaS to help software developers get analysis and historical data about their projects' test coverage, see constant updates in pull requests where devs are working, and fine-grained line-by-line coverage data.
Automated testing has become a foundational element part of software development, and Coveralls lets developers show off the hard work put into building a comprehensive testing suite.
