Code coverage is a metric used to describe the degree to which the source code of a program is tested. A program with high code coverage has been more thoroughly tested and has a lower chance of containing software bugs than a program with low code coverage. You can read more about the basics of code coverage on our blog.
There are many tools that you can use to generate coverage reports for the languages used in your repositories. You can check on our documentation page, how to generate coverage reports, and example coverage tools that generate reports in formats that Codacy supports.
