Codecov highlights which portions of your code that have not been properly tested or may require additional testing, then generates a report on your test suite’s code coverage, and overlays that directly onto your source code, making it even easier to identify needed test areas.
By being able to visually see the exact place in your source code that needs additional testing, engineers can make the needed adjustments in their workflow.
