C# - WPF : testing strategies

Question

I'm new to C# 4.0 and WPF and I'm about to start a new application.

Coming from a C++/MFC world, I'm interested in testing strategies used with the up to date technologies.

For instance:

• Unit Testing
• Functional testing
• UI Testing
• other?

Any advice would be appreciated.

Thanks.

Answer 1

Take a look at White. From their site:

White Automate windows applications https://white-project.googlecode.com/svn/

White is a 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 you are already using. White provides a consistent object-oriented API, hiding the complexity of Microsoft's UIAutomation library (on which White is based) and windows messages. Only stable versions of White are released, so all releases are production-ready.

As Larry said White UI test framework can be used for UI testing WPF. This post explains this in more detail -

Testing WPF applications with the White UI Test framework: http://blogs.msdn.com/b/john_daddamio/archive/2008/04/04/testing-wpf-applications-with-the-white-ui-test-framework.aspx

Also have look at this article to know how to automate the UI testing:

Automating UI Tests In WPF Applications: http://msdn.microsoft.com/en-us/magazine/dd483216.aspx

Xaml team has come up with a XAML Compliance Suite to verify XAML(I haven't tried it myself though) -

Various third-party tools are also available for testing WPF application, like this one from AutomatedQA -

AutomatedQA’s TestComplete is a comprehensive automated testing tool that helps QA teams automate their functional, unit, regression and other testing types for a wide variety of application types, including Windows Presentation Foundation (WPF) applications.

I would also suggest you to go through WPF Application Quality Guide from MS

This document provides an overview of testing Windows Presentation Foundation (WPF) applications and controls.
