This PR adds a basic support for WebDriver BiDi that currently includes only the ability to establish a connection and shutdown the browser. Therefore, the implementation is marked as internal and won't show up in the changelog as it's barely useful at the moment.
The API classes are kept as classes instead of interfaces so that clients relying on instanceof checks still work.
* chore: implement a test runner on top of mocha
This PR implements a test runner on top of mocha
that performs multiple mocha runs as defined in
TestSuites.json and compares the outcome of the runs
against TestExpectations.json. This allows us to
remove most of helpers from mocha-utils and be more
flexible when defining the test configurations.
