Can we make wrapFunctions changes in a separate patch?

I don't think this one is needed, we should not verify WebGL spec here.

Why do you need runTestSuite?

We prefer not to inline functions. Maybe extract generateWebGLErrors instead?

I would replace step2 with next since you are just asserting that the function ended there.

var error = +key; // Convert to Number.

I need to check the return value also (asynchronously) - this will mean there were no exceptions thrown.
