Codecov provides highly integrated tools to group, merge, archive and compare coverage reports. Whether your team is comparing changes in a pull request or reviewing a single commit, Codecov will improve the code review workflow and quality.

Code coverage done right.®

1. Upload coverage reports from your CI builds.
2. Codecov merges all builds and languages into one beautiful coherent report.
3. Get commit statuses, pull request comments and coverage overlay via our browser extension.

When Codecov merges your uploads it keeps track of the CI provider (inc. build details) and user specified context, e.g. #unittest ~ #smoketest or #oldcode ~ #newcode. You can track the #unittest coverage independently of other groups. Learn more here

Through Codecov's Browser Extension reports overlay directly in GitHub UI to assist in code review in Chrome or Firefox (https://addons.mozilla.org/en-US/firefox/addon/codecov/)

Highly detailed pull request comments and customizable commit statuses will improve your team's workflow and code coverage incrementally.

File backed configuration all through the codecov.yml.
