The IDL itself can be tested easily using WPT's IDL test harness and a copy of the IDL from the spec. See, for example, https://github.com/w3c/web-platform-tests/blob/master/encrypted-media/idlharness.html.

We also need tests for as much behavior as we can cover, but the above will test the API definitions very quickly.

Note: Some of the tests may not pass in Blink. See  issue 636112 .

What directory name should we use? I see the draft CL uses "webvr," which makes sense but does not match the source directory third_party/WebKit/Source/modules/vr/. Unless we plan to change the latter, I think the tests should match it.

Add WebVR IDL test

Based off the IDL test for encrypted media
https://cs.chromium.org/chromium/src/third_party/WebKit/LayoutTests/imported/wpt/encrypted-media/idlharness.html

Times out on Android K, but I believe that's expected of IDL tests, as the
encrypted media IDL test also times out.

Needs to run from an HTTP server (hence being in the http directory) due to
fetch() only working with http and https.

Relies on the change in crrev.com/2587223003, as WebVR is not enabled by
default for testing yet. If that change cannot make it in, will have to move
this test to the virtual directory so we can use command line flags.

Add the first layout tests for WebVR to test navigator.getVRDisplays with mocked vr_service mojo interfaces.

We will add more layout tests to cover more WebVR APIs later with same
approach.

Add more WebVR layout tests, adjust test format

Adds a handful of new WebVR layout tests using mocking.

Adjusts the vr_test to pass the provided function an async_test handle. This
was done due to how easy it was for the previous promise_test implementation
to resolve earlier than expected, causing the test to pass before all code was
run with no visible difference in the output. The use of the async_test makes
the tests slightly more verbose, but ensures that we're only ending the test
when we expect to.

Add a fix for VRDisplay not initializing layer bounds to defaults correctly.

Reland 2617183002 without offending tests

2617183002 was reverted in
https://bugs.chromium.org/p/chromium/issues/detail?id=679288 due to a couple
of leaking tests. This is being investigated in
https://bugs.chromium.org/p/chromium/issues/detail?id=679401, but in the
meantime, we can re-land the other tests that weren't causing issues.

I'm going to go ahead and close this, as we have a good amount of layout test coverage here https://cs.chromium.org/chromium/src/third_party/WebKit/LayoutTests/vr/. We also have the IDL test in external/wpt/webvr/.

We're currently missing coverage of WebVR functions that make use of getPose (such as getFrameData), as calls to it hang indefinitely when run in layout tests. bajones@ thinks is due to the Mojo mocking not liking that it's declared as synchronous (it's the only function in the API that is synchronous). I'll see if Michael's patch to make it asynchronous on the back end fixes it, although I think that code would never be reached since we're mocking anyways.

We'll add more layout tests as the spec changes.

Add getFrameData and getPose layout tests

Adds layout tests for WebVR using getFrameData and getPose now that pose
updating doesn't hang indefinitely while mocking.
