Example of mock-MotionEvent for unittest

utmotionevent.py

# subclass for touch event in unit test
class UTMotionEvent(MotionEvent):

    def depack(self, args):
        self.is_touch = True
        self.sx = args['x']
        self.sy = args['y']
        self.profile = ['pos']
        super(UTMotionEvent, self).depack(args)
        
# then create a touch
touch = UTMotionEvent("unittest", 1, {"x": 0, "y": 0})

# dispatch it manually into kivy
# using post_dispatch_input doesn't pass the touch to any input post-proc
# we don't have the capability to dispatch manually a touch at the beginning
# of the input pipeline, except if you create a touch provider and emit them.
from kivy.base import EventLoop
EventLoop.post_dispatch_input("begin", touch)

# reminder, sx/sy must be size agnostic. So must be between 0-1 range.
touch.move({"x": 0.1, "y": 0})
EventLoop.post_dispatch_input("update", touch)

EventLoop.post_dispatch_input("end", touch)

Very usefull, thanks !

Just a few questions :

• What are all the event types we can pass in post_dispatch_input function ?
• How can I do if I want to mouse_touch_down at given coordinates ?
