We'll respond shortly.
Using Rspec 1.2.6 and an expression of some desired behavior such as this:
it "should score 0" do score = 0 score.should == 0 end
Will sometimes result in a ruby warning:
warning: useless use of == in void context
There was a little confusion as to why this warning was sometimes appearing.
It turns out that the warning appears when the command ruby -w is used to run the spec rather than spec.
This seems to be the case when rake is run for a non rails project, say a plugin.
