```
This suggests that we have a network error when fetching and hence the timeout as we are waiting for the page load. One strong indication from the logs is that we see server error for the previous tests. Hence, this could mean some issue on the wpt server.  I will add a clean-up by calling done() after end of each test and see if we get rid of this error.
