This test makes sure that calling the window moving and resizing methods with less than 2 arguments treats the missing arguments as 0. On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". window.resizeTo Tests Testing - resizeTo with 0 arguments PASS window.resizeTo() threw exception TypeError: Failed to execute 'resizeTo' on 'Window': 2 arguments required, but only 0 present..
