You still haven't specified what GUI library you're using or described
your code layout so what I'll say below is very generic. In my mind it
looks very vaguely like this:

# file: myapp.py

def layout(tab):
    tab.add_widget()
    # blah blah blah

if __name__ == "__main__":
    app = App()
    frame = Frame(app)
    tabs = frame.add_tabs(7)
    layout(tabs[0])  # Add widgets to the tab
    bindevents(tabs[0])
    # blah blah blah
    show()

When you run the above script with 'python myapp.py' is runs like
normal. Then you have another script:

# file: test_myapp.py

from myapp import layout

if __name__ == "__main__":
    app = App()
    frame = Frame(app)
    tabs = frame.add_tabs(1)
    layout(tabs[0])  # Add widgets to the tab
    # don't bind anything here
    show()

Now when you run 'python test_myapp.py' it opens up the dummy app. The
same layout() function is used by the real app and the dummy app so
the dummy app gives you a way of checking that it works.
