Having jotted down some models, with some inheritence I tried to run
unit tests. After waiting for rake test_units to run I got a rake of
(if you’ll forgive the play on words). The errors were to do with
tables in the tear down stage. The unknown tables corresponded to
where single table inheritence was used. In other words, these tables
shouldn’t exist. Any thoughts? I can only hope there is another
error lurking in my project.
