Tests that we find controls if they have a range limitation and are out-of-range. On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". ==> :out-of-range doesn't match to an INPUT without a value: PASS document.querySelector("input[type=number]:out-of-range") is null ==> :out-of-range should match to an INPUT with an out-of-range value: PASS document.querySelector("input[type=number]:out-of-range").id is "number1" PASS document.querySelectorAll(":out-of-range").length is 1 ==> When the value becomes in-range dynamically, we do not find the control anymore: PASS document.querySelector("input[type=number]:out-of-range") is null PASS document.querySelectorAll(":out-of-range").length is 0 PASS successfullyParsed is true TEST COMPLETE
