// 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.
