### Question:
InputManager { public static InputManager getInstance () { return instance; } InputManager(); void setGdxInputProcessor(); void add(InputProcessor processor); void addFirst(InputProcessor processor); void remove(InputProcessor processor); boolean contains(InputProcessor processor); void verifyUnique(InputProcessor processor); Array<InputProcessor> getProcessors(); int countProcessors(); void clear(); static InputManager getInstance();  }### Answer:
@Test public void testGetInstance () { InputManager manager = InputManager.getInstance(); InputManager manager1 = InputManager.getInstance(); assertNotNull(manager); assertNotNull(manager1); assertEquals(manager, manager1); }
