Writing unit test for wxPython

I have an built app that contains a window made with wxPython that contains a text box to take inputs from the user, and the enter event is bound to a function and sends a wx.Frame object to it. The input value is accessed with self.txt.GetValue()

I need to write some unit tests for the function but cannot seem to find a way to create and pass an argument to the function in a way that the value will still be accessible with the same statement.

I also found a number of modules for testing python apps, including one on the wxPython page (pyunit), but the main intuition of HOW to pass the value is not clear.

How do I go about doing this?

If you decouple the function from wxPython, you can easily unit test it. So let's say you have a widget bound to an event handler like this:

def on_text_change(self, event):
    my_module.do_something_with_text(self.txt.GetValue())

Now you can add a unit test for my_module.do_something_with_text because it won't depend on wxPython.

If you want to create what amounts to an automated UI test, you can use UIActionSimulator - https://wxpython.org/Phoenix/docs/html/wx.UIActionSimulator.html
