Hey Scott, I'm not sure if there's a way you can currently do that (there may be and I just couldn't figure it out). However I agree it's useful, and I whipped up a quick patch to provide that behavior. http://rubyforge.org/tracker/index.php?func=detail&aid=12841&group_id=797&atid=3151 My example spec is it "should support yielding consecutive values" do yielded_values = [] @obj.stub!(:method_that_yields).and_yield_consecutively("abc", 123, :foobar) @obj.method_that_yields {|val| yielded_values << val } yielded_values.should == [ "abc", 123, :foobar ] @obj.rspec_verify end How's that?
