How to use ScalaTest “contain allOf” on two lists?

Question

I was looking for a ScalaTest matcher to check that a list contains all of the needed elements (given within another list), but that may also be others.

Bill Venners had this to say on the ScalaTest mailing list:

Yes, we didn't want to hold up the 2.0 release to add that, but have since added it. I believe we added it to master, though, not the 2.2.x branch. Regardless, the syntax looks like:

xSet should contain allElementsOf (ySet)
