// 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,
//        options);
//
// The harness will load the fileListURL and parse it for the URLs, one URL
// per line preceded by options, see below. 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(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. 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.
//
// Harness Options
//
// These are passed in to the TestHarness as a JavaScript object
//
// version: (required!)
//
//     Specifies a version used to filter tests. Tests marked as requiring
//     a version greater than this version will not be included.
//
//     example: new TestHarness(...., {version: "3.1.2"});
//
// minVersion:
//
//     Specifies the minimum version a test must require to be included.
//     This basically flips the filter so that only tests marked with
//     --min-version will be included if they are at this minVersion or
//     greater.
//
//     example: new TestHarness(...., {minVersion: "2.3.1"});
//
// maxVersion:
//
//     Specifies the maximum version a test must require to be included.
//     This basically flips the filter so that only tests marked with
//     --max-version will be included if they are at this maxVersion or
//     less.
//
//     example: new TestHarness(...., {maxVersion: "2.3.1"});
//
// fast:
//
//     Specifies to skip any tests marked as slow.
//
//     example: new TestHarness(..., {fast: true});
//
// Test Options:
//
// Any test URL or .txt file can be prefixed by the following options
//
// min-version:
//
//     Sets the minimum version required to include this test. A version is
//     passed into the harness options. Any test marked as requiring a
//     min-version greater than the version passed to the harness is skipped.
//     This allows you to add new tests to a suite of tests for a future
//     version of the suite without including the test in the current version.
//     If no -min-version is specified it is inheriited from the .txt file
//     including it. The default is 1.0.0
//
//     example:  --min-version 2.1.3 sometest.html
//
// max-version:
//
//     Sets the maximum version required to include this test. A version is
//     passed into the harness options. Any test marked as requiring a
//     max-version less than the version passed to the harness is skipped.
//     This allows you to test functionality that has been removed from later
//     versions of the suite.
//     If no -max-version is specified it is inherited from the .txt file
//     including it.
//
//     example:  --max-version 1.9.9 sometest.html
//
// slow:
//
//     Marks a test as slow. Slow tests can be skipped by passing fastOnly: true
//     to the TestHarness. Of course you need to pass all tests but sometimes
//     you'd like to test quickly and run only the fast subset of tests.
//
//     example:  --slow some-test-that-takes-2-mins.html
