+This is a testharness.js-based test.
+FAIL Navigator interface: operation requestKeyboardLock(sequence) assert_throws: calling operation with this = null didn't throw TypeError function "function () {
+            fn.apply(obj, args);
+        }" did not throw
+PASS Navigator interface: operation cancelKeyboardLock() 
+PASS Navigator must be primary interface of navigator 
+PASS Stringification of navigator 
+PASS Navigator interface: navigator must inherit property "requestKeyboardLock" with the proper type (0) 
+PASS Navigator interface: calling requestKeyboardLock(sequence) on navigator with too few arguments must throw TypeError 
+PASS Navigator interface: navigator must inherit property "cancelKeyboardLock" with the proper type (1)
