Another issue with Codecov is that it only calculates it based on the test reports uploaded. In other words, if you have a file that has no tests, it doesn't count towards coverage. You could get 100% coverage, yet only be testing 1 of 10 files. There are a lot of projects out there using Codecov and presenting false coverage information, probably without any clue they are.<p>I recommend using SonarCloud as a much better and comprehensive product.
