Instead of random accusations, I recommend reviewing Brian Marick’s website. He has great examples of testing using code. He also discusses a lot of philosophy related to test automation.
In his book, ‘Everyday scripting using Ruby’, he demonstrates how to test using scripts. Of course, he is still very code focused. It’s still a good example of how to demonstrate what you mean by ‘testing’, rather than just talking about testing. That is another good role model to follow if you want to use code for testing.
