What Reqnroll is

Reqnroll is an open-source, Cucumber-style behavior-driven development test automation framework for .NET, based on the SpecFlow codebase. Teams can write executable specifications in Gherkin’s Given-When-Then format and run them as automated tests of requirements. Reqnroll supports full Gherkin, including tagged Rule blocks, and step definitions using regular expressions or Cucumber Expressions; asynchronous steps and hooks are supported. Scenarios can run with NUnit, MsTest, TUnit, or xUnit, including xUnit v3. Reqnroll supports Windows, Linux, and macOS and is distributed as NuGet packages. Its documented .NET support includes .NET Framework 4.6.2 and newer listed versions through .NET 10.0, though frameworks before .NET 8 are outside Microsoft support. Integrations are documented for Visual Studio, Rider, and Visual Studio Code, and the framework can also be used without an IDE. The Visual Studio extension provides Gherkin highlighting, completion, formatting, navigation between scenarios and step definitions, and code snippet generation. Reqnroll is compatible with SpecFlow and provides a migration guide. Community is free; Professional is listed at €400 per 10 users per year, excluding VAT.
