[PageVisibility] Test Cases

Per action items, we have submitted the following Page Visibility tests cases at http://w3c-test.org/webperf/tests/submission/Microsoft/PageVisibility/:


-          test_api_exists.htm : checks that all attributes and enumeration values within the Page Visibility API are defined and set to the correct value

-          test_iframe.htm : checks that all attributes and enumeration values are also defined and set to the correct value within content documents inside IFrames

-          test_iframe_visibility.htm : checks that the attribute values within IFrame documents matches values within the root document

-          test_minimize.htm: manual test for checking that the correct Page Visibility state transitions occur while minimizing and restoring the browser window

-          test_read_only_conformance.htm : checks that all attributes and enumeration values cannot be overwritten

-          test_tab_switch.htm : automatically opens a new tab twice to ensure that the correct Page Visibility state transitions occur while switching tabs

Please review these test cases and share feedback. Once the working group is happy with the test cases, we can move them to the approved folder.

Thanks,
