It's also interesting to see the response from people when I even pose this question, or any other question that might even remotely cast doubt on the CI/TDD dogma. Another question is: how do we rectify the complexity added to the total body of our source code when we add in really complex tests? Is there a point at which we are adding more complexity and increasing the potential bug surface area?
