This test is failing on mac_bot (but passing elsewhere) because flutter-tester is apparently quitting earlier than expected. Locally it fails with an even weirder error and almost all tests are failing with "Compilation failed" (this isn't happening on the builds, so something is bad on my MacBook). Marking as skip to fix build while investigating; there's no real impact of this test not running; it's testing a tool that its itself used for testing (and not currently in any way that should be affected by this failure).
