DbFit

DbFit is a set of FIT fixtures which enables FIT/FitNesse tests to execute directly against a database. This enables developers to manipulate database objects in a relational tabular form, making database testing and management much easier than with xUnit-style tools. The library is free to use, released under GNU GPL. more information

WebTestFixtures

WebTest Fixtures are an extension to FIT/FitNesse that implement a customer-friendly language for web testing, utilising Selenium Remote Control. WebTest runs inside FitNesse, allowing you to integrate web UI tests into an automated build system, and use other FitNesse fixtures to talk to your domain model, prepare and verify database changes during Web UI tests. Both .NET and Java FitNesse runners are supported, and the library is released under GPL. more information
