The test has passed if: There is a green rectangle covering 1/4 of the testframe area positioned in the lower right corner. There is a blue rectangle covering 1/4 of the testframe area positioned in the upper left corner. There is a yellow rectangle centered inside the blue rectangle, covering half of the area of the blue rectangle.
