This skips some tests that pass with active replay (which doesn't check the output) but fail with passive replay. Valid reasons for this include: - Checking the output of the process (which doesn't run during replay), - Checking files that cannot be captured in the VFS (non-existing or unreadable files or files that are removed during test), Unfortunately there's no good way to mark a test as supported for active replay but unsupported for passive replay because the number and order of API calls needs to be identical during capture and replay. I don't think this is a huge loss however.
