I am not sure what is a correct behaviour, but it seems your patch will change the behaviour. I mean:

Before your patch:
  If test_args.new_baseline is true, self._driver.run_test() always receives 'None' as an image_hash.

After your patch:
  If test_args.new_baseline is true, self._driver.run_test() may receive non-None value as a image_hash if a test has a '.checksum' file.

I am wondering that is your intentional or not.

Can we make _needs_image_checksum a method of TestInput and give TestInput a populate_checksum method that takes port and options as arguments? Maybe it should be populate_checksum_and_uri. Then the filename_to_uri logic could go back into TestInput as well.

[Ojan Vafai]

Whoops. Hit publish too early. I meant to say:
r- just to address the two questions brought up. Otherwise, looks like a good change.

On a side note, this patch would have been much easier to review if it were a rename patch followed by the logic change patch as the rename is trivial and 90% of the diff.

I'm also not sure if the change in behavior matters. I'm fine with the change if you are confident it won't break anything.

Good catch. That was not an intentional change. Will fix in the next patch.

I would prefer not to make these changes. TestInput is really just a data class with no logic that exists so that we don't have to pass a bunch of individual fields around. 

needs_image_checksum (now renamed to test_input_needs_image_checksum is solely concerned with the command line flags passed to NRWT, and so the logic feels like it makes more sense elsewhere, ideally as a member function on the TestShellThread.

Similarly, the fact that TestInput holds a URI field is actually a mistake. The correct signature to Driver.run_test() should be to take a test name (which is a unix-style relative filename), rather than the full path (which is what it's getting) or a URI (which some implementations don't actually need).

TestInput's input parameter should be changed, and URI should be removed (letting the port call filename_to_uri as necessary). I've added FIXMEs for those, and will make the changes in other patches.

Does that all make sense?

[Dirk Pranke]

Oh, I should have mentioned that I realize you possibly made these suggestions because the logic is being repeated in two different places; that's definitely an issue. One of the later patches in this set will eliminate this.

make that _should_fetch_expected_checksum()

True, and good point. I can attempt to isolate things better in the future. I was thinking of both things as part of a general refactoring cleanup that was logically one change.
