fwiw, the v1 devices are single core, and also are the ones that give us some trouble with threading type tasks in tests a lot (we get issues on v1 devices fairly regularly from base_unittests, for example)

[Chromecast] Temporarily disable MidiTaskServiceTest.RunBoundTasks

This test is failing on v1 devices. Disable the test temporarily to
get the dashboards green again so this failure doesn't mask other
failures. Should get re-enabled once the test issue is resolved.

Oops, I found a bug in the test. I will fix it soon. So, can you re-enable it once I submit the fix?

I sent a review request to you; https://chromium-review.googlesource.com/c/575325/

Thanks!

Thanks for the fix, I will re-enable once it lands

Web MIDI: IncrementCount() should be called before signaling

MidiTaskServiceTest.RunBoundTasks failing on v1 chromecast device.
This is because the test increments the count after signaling the event,
and it results in racy results because expectation check could run
before the count is incremented.
This patch fixes this problem and is expected to solve the problem
that RunBoundTasks failing on v1 chromecast device.
