Hi all,

I’m trying to understand how to use Windows Objects, which seem to behave differently to ‘normal’/web test objects.

I can see that I can select an option for Locator Strategy, but the option I want to use (‘AutomationId’ in my case) isn’t present, but I can’t seem to work out how to use a custom option like this.

The Object Properties section appears to do nothing…or have I misunderstood?

So…in other words…if I have an object where it has a property of ‘AutomationId’ with a value of ‘ButtonOK’, how do I go about configuring this in a Windows Object please?

Thanks,  
Kevin
