Running Remote Tests in Parallel on Sauce

This is a list of points to be careful:

• There might be jobs stuck in the queue, since you have a limited test slots, so you have to watch http timeout and retries, one long test might trigger http timeouts and mess up the test suite. This is a good formula to keep in mind: (num_of_jobs - num_of_slot) * max_job_length < http_timeout * retry

• You might need to increase your test suite timeouts to take in account the wait above.

• Session not shared between browsers

• Test isolation

• The server you are testing against, in particular if you are using sauce connect, the start/stop server takes much longer than with local test (This is more an issue related to remote than parallel, but will be more apparent).
