If you definition is loose, then you could probably say that. Generally though, using a TDD approach would result in some form of a test suite that can be used to continually assert the correctness of a program. Personally I attempt to write tests whenever possible, even in a new problem domain. However, I generally only write some general "black box" style tests to start.
