In this blog post, Dror Helper presents a short “getting started” procedure to do Behavior Drive Development (BDD) with SubSpec. SubSpec allows developers to write declarative tests operating in C# at all layers of abstraction consisting of highly composable, small primitive concepts. SubSpec is based on the xUnit testing framework and can easily be integrated into existing testing environments. The blog post shows how to write its first behavior test and how to run all the assertions in one test.
