This is potentially a race between the two processes that are running because they seem to pass when they are run independently. These are the two errors:

I can take a look

#355 fixed this issue. The TestParameters instance was shared among all running tests, thus when mutating settings on it, there are race conditions when executing the tests. The applied fix was to create a unique instance for each test.
