TDD with Acceptance Tests and Unit Tests
There are two different kinds of automated tests recommended by the Agile disciplines. Unit tests, which are written by programmers, for programmers, in a programming language. And acceptance tests, which are written by business people (and QA), for business people, in a high level specification language (like FitNesse www.fitnesse.org).
The question is, how should developers treat these two streams of tests? What is the process? Should they write their unit tests and production code first, and then try to get the acceptance tests to pass? Or should they get the acceptance tests to pass and then backfill with unit tests?
