I'm new to TP can anyone provide best tutorial or any other site for reference with example for checks & events.
The Help has pretty good examples of the syntax behind checks and events... Is there a specific kind of check or event you are looking to get a better understanding of?
you need to have VB knowledge, not 100% but around 80% to work on it. also you can read use help that comes with test partner.
Never test the depth of the water with both feet.
If you're working with the latest releases (6.0 onward), there's a tutorial that is part of the help for both the visual and vba approaches to testing.
