Binding business requirements to .NET code

SpecFlow aims at bridging the communication gap between domain experts and developers by binding business readable behavior specifications and examples to the underlying implementation.

Our mission is to provide a pragmatic and frictionless approach to Specification-By-Example for .NET projects.

SpecFlow also supports the concepts of Acceptance Test Driven Development (ATDD) and Behavior Driven Development (BDD), which are often used synonymously with Specification-By-Example.

SpecFlow is open source and provided under a BSD license. As a part of the Cucumber family, SpecFlow uses the official Gherkin parser and provides integration to the .NET framework, Silverlight, Windows Phone and Mono.
