Coveralls

Coveralls is a web service that shows which parts of the code are not covered by tests, and tracks test coverage over time. Coverage reports are sent from the CI pipeline with integration packages available for many languages.

A dashboard gives an overview of all projects with their current coverage and its evolution. Repository pages show coverage from the total down to sub-projects, files and individual lines, and the build history shows how coverage changes for each build on every branch, including pull requests. Coveralls posts comments and status updates on pull requests, sends notifications and provides coverage badges. It is CI-agnostic and signs in with GitHub, Bitbucket or GitLab.

Coveralls is a commercial service, free for open source repositories, with paid plans for private repositories and an Enterprise edition that runs on the customer’s own servers.
