I am doing on a project to built automatic GUI testing for graphical application in .NET. I will use C# but i am trying to reading to get some ideas. But I don't have any idea on how to record and replay back. So can you give me your ideas.
Here's a blog from the visual studio team that goes over this exact topic. It's about how they tested pre-wpf and post-wpf.
This post covers an overview of techniques that we used to create and maintain automated user interface regression tests for Visual Studio. Regression tests are a type of software test that, collectively, aim to be an oracle of expected functionality for the target application, run often against new builds of product – they aim to uncover regressions in behavior introduced in a new build.
