Summary

FitNesse is a free acceptance-test wiki for writing and checking application acceptance criteria. Teams can record requirements in wiki pages and run those pages as tests against an application, helping keep documentation aligned with expected behavior. Pages can be edited in a browser with wiki syntax or a rich-text editor, and tests can run manually or automatically by anyone with web access to the server. FitNesse is distributed as a Java jar and can run on a machine or server, with wiki pages stored as files. It requires Java Runtime Environment version 11; supported versions listed are Java 11, 17, and 21. Fit and Slim are built-in test systems, and tests can also run from JUnit or Maven. Listed plugins and fixtures include support for Git, Gradle, Selenium, REST and HTTP testing, PDF checks, and email retrieval. Page permissions can separately restrict reading, writing, and testing, but these protections are disabled by default. The security guide also notes that search queries and files in the /files directory remain accessible without authentication unless additional protections are configured.

Who it is for

FitNesse may suit software teams that want requirements expressed as runnable acceptance tests. It is aimed at setups that can run a Java application and configure the wiki's security controls as needed.

What is good

Free and open source.
Wiki pages can be run as application tests.
Pages support browser editing and test feedback.
Built-in test systems include Fit and Slim.
Listed plugins cover Selenium and REST testing.

What to know first

Requires Java Runtime Environment version 11.
Page protections are disabled by default.
Search and /files access do not require authentication.

Verdict

FitNesse combines wiki-based requirements with executable acceptance tests and offers integrations for several testing workflows. Its security controls need attention because page protections are off by default and some access paths do not require authentication.
