User Interface Testing [closed]

Answer 1

There are many tools and libraries available that can automate WinForms testing, ranging from open source solutions like White to the expensive commercial solutions such as HP QuickTest Pro. There is also the UIAutomation namespace in .NET if you want to roll your own automation framework. But the real cost of automation is in the time and specialised skills it requires to implement. Maintainability is also one of the most important aspects of automated test design; you dont want to expend excessive resource keeping the automation assets current with your application. There are also lots of factors influencing the decision to automate which will be specific to your specific application and organisation.

Your best bet will be to do some more research on the subject and check out some of the specialised testing sites such as http://www.sqaforums.com.

Answer 3

I can't really help with organization or best practices, but an NUnit extension appears to be available for forms testing, NUnitForms.

Answer 4

You can automate GUI testing using White framework.

Also consider using TDD friendly design, i.e. use MVP/MVC pattern.

I would highly recommend you to read documentation from Microsoft patterns&practies teams.

Especially have a look at the Composite UI application block and CompositeWPF.

These projects specifically designed to give you best practices in GUI apps development including test driven UI.

Answer 5

There are GUI testing tools that will click buttons and stuff for you but they're pretty fragile in my experience.

The best thing to do is to keep your UI layer as thin as possible. Your event handler classes should optimally be only one or two lines that call out to other more testable classes. That way you can test your business logic in unit tests without having to actually do a button click.
