Because there are three tests, we had better show three 'PASS' in the test result.

No reason to use a comma operator here.

ditto.

> +    return [ r / size, g / size, b / size, a / size ];

nit: spaces after ']' and before ']' are not needed.

The tolerance argument is always specified.  We don't need "tolerance = tolerance || 0".
Also, there is no reason to use a comma operator here.

> +        if (testImage(image, expect), ++loadedImages < 3)

No reason to use a comma operator here.

We shown up to 3 failures should they happen, sufficient?

One day layoutTestController will return its |this| context.  Removed.
