+This is a extended unittest module for Kivy, to make unittests based on

+The idea is to render a Widget tree, and after 1, 2 or more frames, a
+screenshot will be made and be compared to the original one.
+If no screenshot exists for the current test, the very first one will be used.
+
+The screenshots live in the 'kivy/tests/results' folder and are in PNG format,
