No, those steps are the algorithm the engine is supposed to follow. But a test needs to be based on the observable results of the algorithm, not the algorithm itself.

We need to figure out how to detect if a document has an incorrect origin or an incorrect effective script origin by the behavior of the engine.

I presume that the effect of the effective script origin is to restrict script execution, so that test would be about correct restricting script execution and not incorrectly restricting it.

The other test could perhaps be done simply by reading a property that indicates what a document’s origin is. I’m not really sure, because I’m not an expert on this part of the specification. I’d have to study it myself to figure that out.
