This command uses the Chrome Debugging Protocol to run tests in the Chrome browser.
It's designed to be streamlined with the default Node runner so it can leverage the same
Mocha reporters and Nycreporters even if the tests are running in a browser environment. It
also supports the same developer workflow when writing tests e.g only rerun affected tests when
a test or source file is saved.
This runner is using babel and babel-plugin-istanbul to instrument the files before serving them
to the browser. Make sure to add them as devDependencies e.g
npm i --save-dev babel-core babel-plugin-istanbulOptions:
