This Atom package shows your code’s test coverage in the gutter. It guides you towards more code coverage! Inspired by Wallaby.js.

Tested with:

• Mocha + nyc
• Karma + babel-plugin-__coverage__

In this example, I use nyc to capture the code coverage while running Mocha test.

Make sure the coverage data file is generated. It’s usually named lcov.info.

Here I use onchange to monitor the .js files and re-run the tests.
