Drive-by: fix --no-coverage flag in test runner
This PR adds a custom mocha reporter that is a combination
of the Spec + JSON reporters. This way our test runner can
remove custom printing logic for test runs and only output
expectations.
Instead of checking skipped tests in mocha-utils this PR
implements a custom mocha interface for better flexibility
when skipping tests. That should allow skipping tests without
running before and after hooks.
* 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.
