+//! @file fake_animation.h
+//!
+//! Simple fake of the Animation code. Not intended to be a complete drop in replacement, but good
+//! enough for some simple tests.
+
+#include "applib/ui/animation_private.h"
+
+//! @return A pointer to the first animation that was created since we last called
+//! fake_animation_cleanup
+Animation * fake_animation_get_first_animation(void);
+
+//! @return The next animation after the supplied animation. Animations form a link list based on
+//! creation time, and that list can be walked by combining this function with
+//! fake_animation_get_first_animation
+Animation * fake_animation_get_next_animation(Animation *animation);
+
+//! Cleans up all fake animation state. Use between tests to ensure a clean slate.
+void fake_animation_cleanup(void);
+
+//! Runs an animation to completion by scheduling it, setting its elapsed to its duration, and then
+//! unscheduling it.
+//! @param animation The animation to run to completion.
+void fake_animation_complete(Animation *animation);
