I'm not really sure why this is stubbing find, or why the stub value
is true instead of a model. Actually, I don't even see how this would
specify validating uniqueness of the attribute without very specific
setup:
first = Centro.create(:nombre => "example")
second = Centro.create(:nombre => "example")
second.should validate_uniqueness_of(:nombre)
I don't see any specs for the rspec-on-rails-matchers library on
github, and no activity in 9 months, so I'm guessing that it is
incomplete/no longer being maintained.
Josh Knowles, if you're reading this, can you respond?
