Having trouble using the unit test decorator @test.patch_plugs to mock a device I'm testing. about openhtf

Using TestCase.execute_phase_or_test did the trick! Thanks for your help!

1. Make sure your test fixture derives from test.TestCase (imported from openhtf) and not (just) the Python standard unittest.TestCase.
2. Remove the @test.yields_phases, not necessary if you're using patch_plugs

Beyond that, code looks fine? Although it's not clear why you're passing mock_device.calibrate_sst as an argument to htf.Test. You should be passing the phases to test (is calibrate_sst a phase defined on the DevicePlug?)

You could also try using TestCase.execute_phase_or_test and skip the patch_plugs decorator, might be easier to write tests that way. The module docs have examples on how to use this function.

Excellent! I do recommend using execute_phase_or_test over the older @patch_plugs decorator.
