Count of matching tests

To run a set of web-platform-tests tests, specify a path value in the Run tests under path field above. Example paths:

- `/` - runs all of the tests from the root down
- `/websockets` - runs all of the websockets tests
- `/websockets/constructor` - runs all of the websockets/constructor tests
- `/html/syntax/parsing` - runs all of the html/syntax/parsing tests

Multiple test paths can be specified by separating them with comma or whitespace. For example, `/js, /html` will run the js and html tests.

Javascript regular expressions are also supported for filtering. When the option is checked, only a test path matching the regex pattern will run. For example, you can specify `^/js/|^/html/` to run the js and html tests.

If the test runner is run online, the set of tests available to run can be found in the w3c-test.org test repository.

Tests will run in a new window. For reftests and manual tests it’s best to put that window side-by-side with this one.
