A million thanks to @codecov for supporting #opensource with free unlimited repos! Just moved to use codecov’s 🔥coverage reports & it couldn’t have been easier. All it took was just a magic one word cmd in the CI and it Just Works™. . .

Switched from Travis to @circleci, build triggers much faster. Also switched from coveralls to @codecov, the UI is much better.

@codecov Great product! Just got comments for each line that is not covered on my PR.

Sebastian Wild


Got my first #opensource pull request merged. Can't wait that the package gets build and uploaded to #hackage. #codecov-haskell

Andreas Möller


👋 Have you noticed that @codecov now annotates a pull request on @github when you forgot to write tests for production code? ❤️ Very nice!

Gerhard Preuss


@codecov provides great PR comments! You see a separate #coverage for your newly added code (patch)! Give it a try

Alejandro de la Vega


TFW when you thought someone commented on your pull request, but it just @codecov telling you to step your testing game up.

Liran Tal 💚 Node.js Security


it amazes me how far opensource has advanced a package that serves thousands of users is adhering to code coverage thresholds (@codecov), has continuous integration safety net (@travisci), and ensures no security vulnerabilities introduced to the project (@snyksec) 🌈✨

. @codecov is amazing; I've been integrating it into @databricks' open-source Scala projects and it's been a smooth process so far.



Very impressed by @codecov. One line of code added = Now working on coverage for R + Python

@nirgn975 But then I discovered @codecov. They basically scan my repo for coverage reports and merge them for me. It's so easy I'm in love!!
