The Revolution of Test-Driven Development

In the last hundred years, using the doctor metaphor and taking this as far as we can, it was the creation of antibiotics but also the simple washing of hands. That's a really interesting analogy. You can use that in the next genome. It may be that testing or test-driven development is the antibiotic, is the miracle cure. But maybe that is the revolution. And I have been quoted a number of times saying that if you're not doing test- driven development, it's very difficult to call yourself a professional.
