I’m sorry Dave, but you’re wrong, wrong, wrong! :]

The purpose of testing “attributes” is not to test that Moose did its thing. The purpose of testing attributes’ accessors is that they are part of your class’ interface. That an accessor is backed by a Moose attribute is an implementation detail. Just because get_foo() is an attribute accessor today doesn’t mean that the data won’t be stored elsewhere in the future or even be derived from something else.

What you shouldn’t be doing is using has_attribute_ok() from Test::Moose, again because where the data returned by the accessor is coming from shouldn’t matter to users of your class.
