 | |
|  * Add a test function which is a Task function.
 | |
|  *
 | |
|  * @param funcOrProperties
 | |
|  *        An async function to be run or an object represents test properties.
 | |
|  *        Supported properties:
 | |
|  *          skip_if : An arrow function which has an expression to be
 | |
|  *                    evaluated whether the test is skipped or not.
 | |
|  * @param func
 | |
|  *        An async function to be run only if the funcOrProperies is not a function.
 | |
|  *
 | |
|  * Task functions are functions fed into Task.jsm's Task.spawn(). They are async
 | |
|  * functions that emit promises.
 | |
|  *
 | |
|  * If an exception is thrown, a do_check_* comparison fails, or if a rejected
 | |
|  * promise is yielded, the test function aborts immediately and the test is
 | |
|  * reported as a failure.
 | |
|  *
 | |
|  * Unlike add_test(), there is no need to call run_next_test(). The next test
 | |
|  * will run automatically as soon the task function is exhausted. To trigger
 | |
|  * premature (but successful) termination of the function, simply return or
 | |
|  * throw a Task.Result instance.
 | |
|  *
 | |
|  * Example usage:
 | |
|  *
 | |
|  * add_task(async function test() {
 | |
|  *   let result = await Promise.resolve(true);
 | |
|  *
 | |
|  *   do_check_true(result);
 | |
|  *
 | |
|  *   let secondary = await someFunctionThatReturnsAPromise(result);
 | |
|  *   do_check_eq(secondary, "expected value");
 | |
|  * });
 | |
|  *
 | |
|  * add_task(async function test_early_return() {
 | |
|  *   let result = await somethingThatReturnsAPromise();
 | |
|  *
 | |
|  *   if (!result) {
 | |
|  *     // Test is ended immediately, with success.
 | |
|  *     return;
 | |
|  *   }
 | |
|  *
 | |
|  *   do_check_eq(result, "foo");
 | |
|  * });
 | |
|  *
 | |
|  * add_task({
 | |
|  *   skip_if: () => !("@mozilla.org/telephony/volume-service;1" in Components.classes),
 | |

 | |
