-// This is a test harness for running javascript tests in the browser. |
-// The only identifier exposed by this harness is WebGLTestHarnessModule. |
-// |
-// To use it make an HTML page with an iframe. Then call the harness like this |
-// |
-// function reportResults(type, msg, success) { |
-// ... |
-// return true; |
-// } |
-// |
-// var fileListURL = '00_test_list.txt'; |
-// var testHarness = new WebGLTestHarnessModule.TestHarness( |
-// iframe, |
-// fileListURL, |
-// reportResults); |
-// |
-// The harness will load the fileListURL and parse it for the URLs, one URL |
-// per line. URLs should be on the same domain and at the same folder level |
-// or below the main html file. If any URL ends in .txt it will be parsed |
-// as well so you can nest .txt files. URLs inside a .txt file should be |
-// relative to that text file. |
-// |
-// During startup, for each page found the reportFunction will be called with |
-// WebGLTestHarnessModule.TestHarness.reportType.ADD_PAGE and msg will be |
-// the URL of the test. |
-// |
-// Each test is required to call testHarness.reportResults. This is most easily |
-// accomplished by storing that value on the main window with |
-// |
-// window.webglTestHarness = testHarness |
-// |
-// and then adding these to functions to your tests. |
-// |
-// function reportTestResultsToHarness(success, msg) { |
-// if (window.parent.webglTestHarness) { |
-// window.parent.webglTestHarness.reportResults(success, msg); |
-// } |
-// } |
-// |
-// function notifyFinishedToHarness() { |
-// if (window.parent.webglTestHarness) { |
-// window.parent.webglTestHarness.notifyFinished(); |
-// } |
-// } |
-// |
-// This way your tests will still run without the harness and you can use |
-// any testing framework you want. |
-// |
-// Each test should call reportTestResultsToHarness with true for success if it |
-// succeeded and false if it fail followed and any message it wants to |
-// associate with the test. 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(); |
-// |
-// 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. You may return false if you want the test to be |
-// skipped. |
-// |
-// For each test completed the reportFunction will be called with |
-// with WebGLTestHarnessModule.TestHarness.reportType.TEST_RESULT, |
-// success = true on success, false on failure, undefined on timeout |
-// and msg is any message the test choose to pass on. |
-// |
-// When all the tests on the page have finished your page must call |
-// notifyFinishedToHarness. If notifyFinishedToHarness is not called |
-// the harness will assume the test timed out. |
-// |
-// When all the tests on a page have finished OR the page as timed out the |
-// reportFunction will be called with |
-// WebGLTestHarnessModule.TestHarness.reportType.FINISH_PAGE |
-// where success = true if the page has completed or undefined if the page timed |
-// out. |
-// |
-// Finally, when all the tests have completed the reportFunction will be called |
-// with WebGLTestHarnessModule.TestHarness.reportType.FINISHED_ALL_TESTS. |
