What Reqnroll is

Reqnroll is an open-source, Cucumber-style behavior-driven test automation framework for .NET and a reboot of SpecFlow. Teams write executable specifications in Gherkin's Given-When-Then format and turn them into automated tests of requirements. It supports full Gherkin, including tagged Rule blocks, along with 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 works on Windows, Linux, and macOS and is distributed through NuGet packages. Its documented .NET support spans .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 it can also be used without an IDE. The Visual Studio extension provides Gherkin highlighting, completion, formatting, navigation, and code snippet generation. Community is free; Professional is listed at €400 per 10 users per year, excluding VAT.

Who it suits

Reqnroll suits .NET teams that want to express requirements as Gherkin scenarios and run them with a supported test runner. Teams migrating from SpecFlow can use its compatibility and migration guide.
