I am getting involved in testing windows application that some of our friends undertake in private from local client. it is going to be a windows application rather and can you guys let me suggest a good functional open source testing tool to test windows app. i searched in google and from discussions i feel "Win 32:GUI" is better. is there any tool you guys can direct me to so that i can assess and implement for my project.
Take a look at TestComplete by AutomatedQA ( http://www.testcomplete.com ). It is not open source but has great features at a good price. We have used it for over a year and have automated all our regression tests with very good results. It also fully integrates with Software Planner ( http://www.softwareplanner.com ) -- allowing you to manage both automated and manual test cases in a single place.
