I'm confused by this statement.

A constant on the class or in the file would read better than checking in each place.

This is more clear, but I'm still confused why os.path.sep isn't our friend here?

Maybe it isn't worth the effort to make this platform-agnostic.  I don't know.  That's your judgment call to make.  But it's not immediately obvious to me why it's not platform-agnostic automatically if we're using os.path.sep where we're supposed to.  I don't see any '/' in these tests themselves.  Should we be making this check inside assertOverridesWorked instead of in each test?

What does the failure look like?

I think the real bug here is that these tests should talk to a MockFileSystem.  Since they aren't, they arent' unit tests and the file should be renamed _integrationtest.py appropriately.

Do integration_test methods get run?

[Dirk Pranke]

The GPU failures (prior to the patch, obviously) looked like:

======================================================================
ERROR: test_get_chromium_gpu__on_linux (webkitpy.layout_tests.port.chromium_gpu_unittest.ChromiumGp

----------------------------------------------------------------------

Not by default. When you run the test files directly you can run them by specifying the -i flag, e.g.: pythom chromium_gpu_unittest.py -i

I would have put a lot of money on me either having added the -i flag to test-webkitpy, or at least filed a bug and posted a patch for it, but I'm not finding it now, so I'll file another bug for it.

[Dirk Pranke]

Filed bug 64137 for adding integration test support to test-wekbitpy.

Note that I did not rename the file in this patch, just so you can actually see the diff.
