Actually, I've constructed a framework that uses a combination of DDT and ODT to create different tests for different areas of the software using minimally 3 CSV files.. I'm testing web pages, SQL stored procedures, and other areas of our system with a simple set of CSV's. If I want to add a new test, I add new records to a csv with certain values that indicate what area is being tested and what supporting data is needed. Each test case consists of several rows in a CSV describing the steps. Each row in the CSV represents a step and generates a different class of ODT object. I then use the ODT method of executing tests (calling a "run" method on each object) to walk through those objects and execute the specific step each object represents.
