There are three different test suites
Tests are extracted from the WPT tests. They help debugging the function under test. Their failure or passing is not necessarily an indication of the state of the package. This uses the source.
Runs the web-platform-tests of accname in jsdom. Needs built package.
Runs the web-platform-tests of accname in cypress. This is an actual browser
test that should be considered first when talking about the state of this package.
Needs built package.
No idea how I would make this run. Ideally I can run the wpt test in every browser.
