In their own words

Concordion

Concordion is a free, open-source tool for turning written specifications into executable checks and living documentation. Those checks run against the system under test; when they run, Concordion generates documentation that marks passing and failing assertions and shows expected and actual values for failures. The output can include tables and links to other specifications. The project offers Java specifications in Markdown or HTML, along with C# options. Java fixtures use JUnit, and Concordion.NET is documented with NUnit. Integrations include IntelliJ IDEA, Eclipse, Gradle, Maven, command-line execution, Jenkins, and Spring. The IntelliJ plugin supports HTML and Markdown, while Eclipse supports HTML specifications but not Markdown. Extensions can add commands, event listeners, or documentation changes, with examples such as Excel specifications, parallel runs, screenshots, and logging tools. Concordion runs locally on Linux, macOS, and Windows, and is licensed under Apache License 2.0. It is maintained by volunteers.
