web-platform-tests dashboard ? 
wpt.fyi is a dashboard of cross-browser results for web-platform-tests, the data for which is uploaded by external services, primarily from various CI integrations in the wpt repo.
Backend: An App Engine app for storing test run metadata and serving HTML
Frontend: Polymer elements for loading and visualizing test results
Setting up your environment
You'll need Docker. With Docker installed, build the base image and development image, and start a development server instance:
docker build -t wptd-dev .
./util/docker-dev/run.sh
This starts a Docker instance named wptd-dev-instance.
Running locally
Once the instance is running, you can fire up the web server in another terminal:
./util/docker-dev/web_server.sh
This will build dependencies and start the Google App Engine development server inside wptd-dev-instance.
With the webserver running, you'll also need to populate the app datastore with some initial data. In another terminal,
execute the script which leverages util/populate_dev_data.go by running:
./util/docker-dev/dev_data.sh
See CONTRIBUTING.md for more information on local development.
Filesystem and network output
- This script will only write files under
config['build_path']. - One run will write approximately 111MB to the filesystem.
- If --upload is specified, it will upload that 111MB of results to GCS.
- To upload results, you must be logged in with
gcloudin thewpt.fyiproject.
Using the data
All test result data is public. Please use our APIs to explore the data. For example, use the results API to download result summaries, and use the runs API to query runs and their metadata, which include links to other data like raw full reports.
Large-scale analysis
There is no public API for TestRuns, so if you need to access only the most recent results, looking at
the main page will give you the latest test SHAs. If you need to access earlier results, an
exhaustive search is the only way to do that (see issue #73 and #43).

This doesn't work with some HTTPS tests. Also be advised that the server is not intended for frequent large-scale test runs.

Platform ID
These are the keys in webapp/browsers.json. They're used to identify a tuple (browser name, browser version, os name, os version).
