xUnit.net is an open source unit testing tool for the .NET Framework. Written by the original inventor of NUnit v2, xUnit.net is the latest technology for unit testing C#, F#, VB.NET and other .NET languages. xUnit.net works with ReSharper, CodeRush, TestDriven.NET and Xamarin.
.NET software testing tutorials: unit testing, open source, NUnit, SpecFlow, Visual Studio, etc.
Part of the .NET Foundation, xUnit.net is an open source unit testing tool for the .NET Framework (C#, F#, VB.NET, etc). xUnit.net works with ReSharper, CodeRush, TestDriven.NET and Xamarin.
Behavior-Driven Development (BDD) is an Agile approach that mixes requirement gathering, documentation and acceptance testing. You write human-readable sentences describing the features of your application and how they should work. Then you implement this behavior using a tool that produces automated acceptance tests to verify that the feature is implemented correctly. Open source .NET BDD tools like SpecFlow are used to store the requirements as live documentation and to perform functional or acceptance tests.
Continuous Testing is the process of executing automated tests as part of the software delivery pipeline to obtain immediate feedback on the business risks associated with a software release candidate. This practice is strongly associated to the Continuous Delivery approach. In his article “Continuous Testing in .NET”, Damir Arh proposes an overview of continuous testing and how to implement it in Visual Studio.
SpecFlow is an open source Behavior-Driven Development (BDD) tool for .NET. SpecFlow uses the official Gherkin parser and supports the .NET framework, Xamarin and Mono. You can use SpecFlow to define, manage and automatically execute human-readable acceptance tests in .NET projects. Writing easily understandable tests is a cornerstone of the BDD paradigm and also helps build up a living documentation of your system. Anton Angelov has created a series of articles dedicated to Specflow that starts with an introduction tutorial.
Creating good, effective unit tests in .NET can be harder than it seems. In some cases, the code is designed so that isolating one component from another is easy. However, in most other cases, achieving this isolation is very difficult. First included in Visual Studio 2012, Microsoft Fakes helps you cross this gap.
Web application testing is a rapidly evolving topic, so year by year it is reasonable to enumerate the possible options and re-evaluate the web testing strategy you have chosen for your .NET project.
