I quite often get my brakes tested.
Coming home from the city a few nights ago I had a kangaroo just off the edge of the road - All you can do is just hit both brakes to slow as quickly as you can and be ready to let go of the brakes to avoid the animal if it decides to cross the road. Lucky that night it kept feeding.
Even had a fox that night in the middle of the road - a double avoid move that was - fox went right I aim left and I brake, fox doubles back and I had a rather quick RH avoid and just missed it. At night I try to keep just left of centreline of the road if there's no on coming traffic - just gives a little more room to move either way.
