This tutorial shows how BDD can be done from early requirement collection stage to late integration tests. It explains breaking user stories into behaviors, and then developers and test engineers taking the behavior specs and writing a WCF service and unit test for it, in parallel, and then eventually integrating the WCF service and doing the integration tests. It introduces how mocking is done using the Moq library. Moreover, it shows a way how you can write test once and do both unit and integration tests at the flip of …

Behavior-Driven Development is more than a technique for creating and organizing unit tests. It is also a wonderful way to communicate with customers and users about the software being created. This video demonstrates some techniques and tools you can use to start delivering software with BDD. : Using Behavior-Driven Development frameworks, this session explores ways to create software starting with solid Agile requirements, moving all the way through automated testing. We use .NET in C# and Visual Studio ALM, although none of these exact tools are required to accomplish the …

Cucumber is a tool that can execute plain-text functional descriptions as automated tests. The language that Cucumber understands is called Gherkin. While Cucumber can be thought of as a “testing” tool, the intent of the tool is to support BDD. This means that the “tests” (plain text feature descriptions with scenarios) are typically written before anything else and verified by business analysts, domain experts, etc. non technical stakeholders. The production code is then written outside-in, to make the stories pass. Cucumber itself is written in Ruby, but it can be …
