Behavior-Driven Development (BDD) agile testing articles, tools, tutorials and videos.
Martin Flower defines legacy code as code without tests. You test your server-side code, but if you are working on a site with a fair amount of non-trivial JavaScript (ajax call, extensive callbacks, etc.) you really should be testing your JavaScript as well. All the untested JavaScript code we are writing today is, in effect, legacy code, but we can address this with JavaScript unit testing!
This article from David Sale provides a short introduction to Behavior-Driven Development in Python. The article presents the principles of Behavior Driven Development and present the syntax of the Gherkin language that can be used with the freshen Python package, a clone of the famous Cucumber BDD framework written for Ruby. Freshen is an open source acceptance testing framework for Python that uses (mostly) the same syntax as Cucumber. A small step by step example is provided on how to use freshen and alternative tools are proposed.
This article provides a general overview of behaviour-driven development (BDD) in a .NET context. I presents some .NET tools for BDD (SpecFlow) and UI testing (White) and proceeds with a working example giving hands on BDD in .NET. SpecFlow is an open source tool aims to provide a pragmatic and frictionless approach to Acceptance Test Driven Development and Behavior Driven Development for .NET projects. White is an open source framework for automating rich client applications based on Win32, WinForms, WPF, Silverlight and SWT (Java) platforms. It is .NET based and does not require the use of any proprietary scripting languages. Tests automation programs using White can be written with whatever .NET language, IDE and tools.
Software tests never run fast enough. To improve this performance, this article presents a process called DMAIC (Define, Measure, Analyze, Improve, Control). It shows how to apply this approach with Cucumber, an open source Behavior Driven Development tool. Cucumber lets you describe how software should behave in plain text. The text is written in a business-readable domain-specific language and serves as requirements documentation and source of automated acceptance tests.
Behaviour Driven Development (BDD) is a different way of approaching the “how to validate your code” problem. It aims to help focus development on the delivery of prioritized, verifiable business value by providing a common vocabulary. This video discusses various ways to try out BDD in Python, from the periodically maligned doctests to simple unittest module usages to more specialized modules.
Codeception is a Behavior Driven Development (BDD) testing PHP framework. It aims to provide an original way to write acceptance, functional and unit tests. It uses a scenario approach where you declare what you are doing and what results you expect from your tests. The first post introduces the tool and explains how to write tests with Codeception. A second post digs deeper into the code and shows you how Codeception could be used for unit testing.
Behavior-driven development (BDD) is similar to test-driven development (TDD), but the tests for BDD are written in an easier-to-understand language so that developers and clients alike can clearly understand what is being tested. In this article based on chapter 2 of Rails 3 in Action, the authors discuss two tools for BDD: RSpec and Cucumber.
