BddDotNet vs Karate

BddDotNet is an open-source behavior-driven development framework for C# and .NET. It supports scenarios written in Gherkin or assembled in C# through a builder pattern. Its Gherkin source generator compiles feature files and registers steps; step arguments can use C# expressions, and table arguments can be converted into C# models. The framework uses Microsoft.Testing.Platform and is based on Microsoft.Extensions.*. The project says it supports .NET 10+ runtimes and is suited to Native AOT deployment and trimming. Public interfaces and dependency injection provide extension points, while additional features are available in separate NuGet packages. To add it to a .NET project, install BddDotNet and its Gherkin source generator as NuGet packages. Setup examples use a console application created with Visual Studio or the .NET CLI, and a GitHub wiki provides setup and feature documentation. It runs locally on Linux, macOS, and Windows. BddDotNet is free under the MIT license, whose terms permit use, modification, distribution, and sublicensing; the software is provided without warranty.
