Towards Spec-Driven Test Automation: Part 1
The problem is that both the code and the tests come from the same reading of the same ambiguous sentences, which means the tests cannot disagree with the implementation. It says that the gap to the car ahead "must be a distance the forward radar can measure, up to its rated range of 250m." Up to 250m, starting where? Unfortunately, this type of specification vagueness means that the software developer who is assigned this task will have to make that decision.

The problem is that both the code and the tests come from the same reading of the same ambiguous sentences, which means the tests cannot disagree with the implementation.
