The Application Under Test uses behaviours to implement validation on Entry fields, performing the validation each time a character is typed. That includes when the user backspaces.
When using UITest, I started with ClearText to get to a known starting point on each Entry, then used EnterText to populate the Entry. However, there are times when I want to test what happens if the user backspaces until the Entry is empty. Unfortunately, ClearText doesn't seem to trigger the validation behaviour, so I seem to need to enter a string using EnterText and then backspace it out in order to trigger the validation when the Entry is empty. I tried "1\b", but this results in an error of "failed to locate key '\b'".
Can anybody tell me how to "populate" an Entry with an empty string, using UITest in such a way that a validation behaviour is fired in the AUT?
