Q:

Simplest and cheapest way to start WPF testing

I have a (closed source) WPF application containing mainly two modules: A UI exe and a "Model" dll. One screen (for now) and about 30 classes.
I would like to start testing it with testing tools.
I have resharper. 
I don't have time :). I don't want to strat learning about factories, mocking, IOC and so on. And I don't want to disturb the code too much (re IOC etc.)
I don't have alota money. I saw a recommendation here for SmartBear's TestComplete and then I saw its $2K price tag and I balked at the price: at $99 I would weep at pay, and you can't beat free :)
So, my question is: "What is the simplest and cheapest way for me to start WPF testing, not necessarily the best colution but something that will provide some benefit at low cost?"

A:

If you want to go to the free route, you can have a look at System.Windows.Automation namespace : http://msdn.microsoft.com/en-us/library/system.windows.automation.aspx
