Hello,
I have created a small application in C#! I want to do testing of it. Please suggest me some good testing tools!

That's VERY subjective depending on the type of application.
What needs to be tested?

Mostly GUI testing, no database at all

Are you talking about something like this?

I need open source testing tool for my C# desktop application!
