The contract code provides a callback whose return result will
be made available to the test that started this contract. The
supplied callback will only be called in a testing context,
never in production; i.e., it is only called if testJigSetter
was supplied.
If no testFn is supplied, then an empty jig will be used.
An additional zcf property set to the current ContractFacet
will be appended to the returned jig object (overriding any
provided by the testFn).
Provide a jig object for testing purposes only.
