You're confusing me now :)
So, if I understand correctly, this fails:
Forum.count.should == counts.to_i
and this passes
Forurm.count == counts.to_i
The fact that the latter is passing is a false positive, because it is
not actually testing anything. It is a boolean statement that returns
true or false, and it doesn't matter whether it returns true or false
because the step will pass in either case. The only thing that makes a
step fail is an error. When you say "Forum.count.should ==
counts.to_i" and those two values are not equal, an ExpectationNotMet
error is raised by RSpec. In that case you get a failure.
The reason "Forum.count.should == counts.to_i" is failing is because
