Karate vs Reqnroll

Karate is a testing framework for API, UI, mock, and performance work. Its MIT-licensed core is free for commercial projects and supports REST, GraphQL, and SOAP testing, with JSON and XML assertions and schema validation. It can automate browsers and desktop apps, and combine UI and API steps in one test. Built-in Gatling integration lets teams reuse API tests for performance testing. The Free plan costs nothing and includes community support. Paid plans include IDE Plus at $100 a year, Xplorer Premium at $200 a year, and Pro at $640 a year; Pro adds IDE plugins, debugging, enhanced autocomplete, development async protocol testing, and priority email support. The platform lists integrations including AWS, Google Cloud, Azure, Jenkins, GitHub Actions, Maven, Gradle, Docker, IntelliJ, VS Code, and Gatling. Enterprise async protocol testing covers Kafka, gRPC, and WebSocket, but production CI/CD execution requires an Enterprise runtime license. Platforms include API, extension, Linux, macOS, self-hosted, and Windows.

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.
