Try this:
module Example
describe "A class defined in before" do
before do
class Item
@@var ||= 0
@@var += 1
def self.var
@@var
end
end
end
it "should be redefined the first time" do
Item.var.should == 1
end
it "should be redefined the second time" do
Item.var.should == 1
end
after do
Example.send(:remove_const, 'Item')
end
end
end
It will fail without the after, so the after definitely undefines the
class so it can be redefined completely the next time.
