Bug 169196 – [css-grid] Import W3C Test Suite

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Manuel Rego Casasnovas]

Blink has already imported the W3C Test Suite and it'd be nice to do the same for WebKit.
That way we could very easily share tests between both implementations.

The suite is at csswg-test repository: https://github.com/w3c/csswg-test/tree/master/css-grid-1

I've started to work on this, but first I need to do a small change on the test suite:
https://github.com/w3c/csswg-test/pull/1229

So I've imported the test suite and uploaded the patch.

Most of the tests are passing but there are a few failures for different reasons:
* CSSOM serialization of grid shorthands (bug #149891)
* min-content and max-content prefixes (bug #169195)
* "normal" => "start" for replaced grid items (bug #169198)
* Transferred size to calculate minimum size of grid items (bug #169197)

As you can see there are bugs reported for each of them,
so once they're solved the tests can be enabled on LayoutTestExpectations.

Current vs expected output for css-grid-1/grid-items/grid-items-sizing-alignment-001.html

Note that some tests return the following result (at least on Linux):
  imported/w3c/csswg-test/css-grid-1/grid-items/grid-items-sizing-alignment-001.html -> ref test hashes didn't match but diff passed 

This is wrong as you can see in the attached image, the test is clearly failing.
That's the reason why I'm marking them as Failures on the TestExpectation file.

Great to see new tests being imported!

Would you also consider updating LayoutTests/imported/w3c/resources/import-expectations.json?
Basically change "csswg-test/css-grid-1"from "skip"to "import"

Sure, I didn't realize about that file.

Thanks for the review.
