First, we define a couple of interfaces, and put them in the

canonical.launchpad.ftests module.

lp.testing module.

Next, we define a FacetMenu subclass to be used for IThingHavingFacets,
592
592
using a usedfor class attribute to say what interface it is to be
593
 
registered for, and put it too in the canonical.launchpad.ftests module.

Now, check that we have no IFacetMenu adapter for an IThingHavingFacets
