Behat vs Reqnroll

Behat is free, open-source software for writing executable specifications in plain language on Linux. It is the PHP implementation of Cucumber and runs Gherkin feature files. Those files can describe complete application behavior and be exercised through browser automation, HTTP API calls, shell commands, databases, filesystems, or PHP code. Behat is intended to work with any PHP framework or without one. Installation uses Composer or a PHAR executable, both running with PHP. An extension system can expand or replace nearly any part of the tool, with extensions covering framework integrations, browser automation, test reporting, and data fixtures. Behat does not provide its own assertion tool, so an external assertion library is needed. It supports current PHP and third-party dependency versions; Symfony 8 support begins with Behat 4.0. Each major version receives security fixes for 24 months after the next major release.

Reqnroll is an open-source.NET framework for turning behavior specifications into automated tests. Teams write executable scenarios in Gherkin’s Given-When-Then format to check whether software meets stated requirements. It supports full Gherkin, including tagged Rule blocks, and step definitions written with regular expressions or Cucumber Expressions; asynchronous steps and hooks are supported. Scenarios can run with NUnit, MsTest, TUnit, or xUnit, including xUnit v3. Reqnroll runs on Windows, Linux, and macOS, and documents.NET Framework 4.6.2 and newer listed versions through.NET 10.0; frameworks before.NET 8 are outside Microsoft support. It is distributed as NuGet packages and documents integrations for Visual Studio, Rider, and Visual Studio Code, though an IDE is not required. The Visual Studio extension adds Gherkin editing tools, navigation, and code snippet generation. Reqnroll is based on the SpecFlow codebase, is compatible with SpecFlow, and has a migration guide. Community use is free; Professional is billed at €400 per 10 users per year, excluding VAT.
