Xcode 10 UI Tests now have the feature of allowing parallel test execution to greatly speed up tests.
However, enabling this (via Product -> Scheme -> Edit Scheme -> Test -> Options), results in bitrise getting confused and failing with no obvious error message. Digging through the raw logs, I can find messages like:
MyAppTests-Runner.app encountered an error (DTServiceHubClient failed to bless service hub for simulator Clone 2 of iPad Air (79CFCC8D-8047-4774-83FD-E439CAA58944))
Clone 1 tests run ok, though the results are not reported.
For now, I’ll disable parallel tests, but I’m wondering what plans bitrise might have to support these? Thanks!
