Mozilla Code Coverage frontend

This is a simple JavaScript application displaying information from the Mozilla code coverage backend (hosted as https://coverage.moz.tools)

You can use it right now from coverage.moz.tools

File viewer

You can browse the aggregated code coverage data for mozilla-central, per directory, then view file coverage in detail.

Zero coverage reports

We've also developed a page to easily browse the directories & files with no coverage: these files are interesting because they can sometimes be removed altogether from mozilla-central...

Developer setup

It's a pretty simple Single Page application setup using webpack:

npm install
npm run start

The frontend should now be available on http://localhost:9000/ and will use a backend running on http://localhost:8000/

You can specify another remote backend like so:

BACKEND_URL=https://api.coverage.moz.tools npm run start
