Hi Ashury,
I'm not sure to understand clearly what you try to do. But Yes you can check the state of a field after some mouse/keyboard events.
Look at EmulateInput in the help.
To make it simple for you, here is how you can start:
1. Go in the view you want to test.
2. Click on record a new test scenario in the tool bar.
3. Then click on "Start recording"
4. Do some stuff in your form... click on the field, type some input, hit the TAB key, etc. Your code will do it's process.
5. Close your applications.
6. Back in the test unit, you will see all the commands you did.
7. You can then hack the code to make it behave as required in your test: like checking the value of a field after exiting (tab key).
Use TestWriteResult procedure, etc.
Regards.
