| Tests to check that the WebGPU IDL is correctly implemented, for examples that objects exposed | |
| exactly the correct members, and that methods throw when passed incomplete dictionaries. | |
| See https://github.com/gpuweb/cts/issues/332 | |
| TODO: exposed.html.ts: Test all WebGPU interfaces instead of just some of them. | |
| TODO: Check prototype chains. (Add a helper in IDLTest for this.) |
