each with a few sentences on why with Agile one does not need them,
and/or why they are covered by regression tests ...
To gain knowledge, add something every day;
to gain wisdom, remove something every day.

Couldn't we write the tests such that they don't look like tests, but rather requirements?
With one, and only one formal specification, which also happens to be executable against the actual system, aren't we better off than having to split time between two possibly out-of-sync artifacts?
ThoughtWorks has a testing tool called Twist, which uses something called Business Workflows. And now it has a nestable declarative aggregator called a "Concept" (what a concept!).
Twist is... designed to help you deliver applications fully aligned with your business. It eliminates requirements mismatch as business users directly express intent in their domain language.
I have not used the tool myself. If anyone has, please add some insight.
P.S. I have no affiliation w/ ThoughtWorks.

What does the requirements document provide that the tests don't? Couldn't we write the tests such that they don't look like tests, but rather requirements?
