BddDotNet vs Cucumber Open

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.

Cucumber Open runs automated acceptance tests from specifications written in plain language, helping teams check whether software behaves as described. It supports Behaviour-Driven Development by executing Gherkin specifications saved in `.feature` text files, typically alongside software in source control. Step definitions link the specification's steps to code that carries them out. Official implementations include JavaScript, Java, Ruby, Android Java, Kotlin, Scala, and C++, with semi-official and unofficial implementations also listed. Gherkin has variations for spoken languages, so teams can use keywords in their own language. Reporting options include built-in HTML, JSON, JUnit, and progress formatters, as well as custom formatters. Cucumber can run in continuous integration environments; its documentation describes JUnit output and a Jenkins reporting plugin. The project is free and open source, with local execution, parallel execution, browser testing, and API access. Published Cucumber Reports are public without authentication and deleted after 24 hours; the report service says data is stored in US data centers and encrypted at rest.
