Simple example of implementing selenium-like testing for kivy

Implemented using kivy's Clock mechanism.

HowTo:

• install all dependencies
• start using ./test.sh

Assertions marked with green rectangle, taps marked with purple circle. Every test must be decorated with @simulate, get simulator as only argument. Also if you don't want to parametrize the test, you still also need to decorate it with @pytest.mark.parametrize("params", [{}]).
