This test creates the + following marks to test this method: + <ul> + <li>"mark1"</li> + <li>"mark2"</li> + </ul> + After creating each mark, performance.clearMarks() is called three times. First, it is provided with a name + of "markUndefined", a non-existent mark, which shouldn't change the state of the Performance Timeline. Next, + it is provided with a name of "mark2", after which, this mark should no longer be present in the Performance + Timeline. Finally, performance.clearMarks() is called without any name provided. After this call, no marks + should be present in the Performance Timeline. The state of the Performance Timeline is tested with the + performance.getEntriesByType() and performance.getEntries() methods. + </p> + + <div id="log"></div> + </body> +</html> |
