  4. Choose **"Install dependencies and run tests":** This should take 15-20 minutes when run with `--npm -l chrome` or `--npm --module-resolution=node -l chrome` flags (We specifically include "-l chrome" to only run tests in Chrome. Testing 90+ elements across multiple browsers is the goal, but it currently takes too long and generates too much noise to reliably parse.)
