This reporter is intended to give a breakdown of test results in a way that is quite clear exactly what has been run, skipped, or failed, and what the results for the tests are on a browser-by-browser basis.
It is a standalone reporter, and is partially based on Karma Summary Reporter which is really great, but didn't offer quite as much as I wanted.
Install via NPM:
npm install --save-dev karma-traackr-reporter
Add to your Karma Config (karma.conf.js):
config.set({
reporters: ['traackr']
});
