To add new tests results:
- Produce a set of JSON test result files using http://w3c-test.org/tools/runner/index.html (or a local copy)
- Push the results into the right directory in this repo (using the same name as the directory in WPT). Create the directory if it doesn't exist.
- generate the report using wptreport https://www.npmjs.org/package/wptreport
