Hi @onlsol Thanks for submitting this adapter.

Overall everything looks good. The only thing I would ask to update is to remove the commented lines of code from the adapter file.

We should all set then.

@jsnellbaker Done. I pushed new commit with changes.

@onlsol Thanks for making the update. I ran the circleCI tests locally and found everything was passing successfully. It only failed here because it was trying to run them with a different account that didn't have access to browserstack.
