If your testing framework supports checking for +// timeout you can call it with success equal to undefined in that case. +// +// To run the tests, call testHarness.runTests(options); +// +// For each test run, before the page is loaded the reportFunction will be +// called with WebGLTestHarnessModule.TestHarness.reportType.START_PAGE and msg +// will be the URL of the test.
