What is Fit?

The Framework for Integrated Test (Fit) is the most well-known implementation (open source framework) of the table-based acceptance testing approach.

Fit lets customers and analysts write “executable” acceptance tests using simple HTML tables.

Developers write “fixtures” to link the test cases with the actual system itself.

Fit compares these test cases, written using HTML tables, with actual values, returned by the system, and highlights the results with colors and annotations.
