# Testing ## Unit, Lint ``` npm run test ``` ## Browser ``` npm run test-browser ``` **You'll need to specify a valid Mapbox Access Token in the URL** for the tests to pass. ``` http://localhost:8080/?access_token=MAPBOX_ACCESS_TOKEN ``` # Bumping Mapbox Version Always pin Mapbox to a specific release. The React controls (`NavigationControl`, `Popup` and `Marker`) are dependent on the Mapbox stylesheet, and may be broken by Mapbox updates. Always run `examples/controls` after bumping Mapbox version to make sure they still work.
