Welcome to BddDotNet

BddDotNet is modern and opensource BDD framework for C# and .NET with gherkin support

Alternative implementations

• Reqnroll
• Specflow (Deprecated, source code no longer available)

Comparing with alternatives

Comparing with Reqnroll (or Specflow, other popular framework in .NET Ecosystem) this framework has following difference:

• Microsoft.Extensions.* based
• Microsoft testing platform as a backend. No hell with different unit tests providers.
• Source generator for features compilation & step registration
• Code first approach with builder pattern
• Extensibility via public interfaces and DI
• Modular. Small and fast library. All extra features are provided as separate nuget packages
• No reflection usage (or quite limited)
• Support .NET 8+ and .NET Framework 4.7.2+ (we recommend to use .NET 10 as best option if possible)
• AOT & Trimming friendly. More info: Native AOT deployment
• Nullable reference types and other modern dotnet features support
