| 60 * @param object aOptions | |
| 61 * Options object with the following properties: | |
| 62 * - validator | |
| 63 * A validator function that should return the expected value. This is | |
| 64 * called every few milliseconds to check if the result is the expected | |
| 65 * one. When the returned result is the expected one, then the |success| | |
| 66 * function is called and polling stops. If |validator| never returns | |
| 67 * the expected value, then polling timeouts after several tries and | |
| 68 * a failure is recorded - the given |failure| function is invoked. | |
| 69 * - success | |
| 70 * A function called when the validator function returns the expected | |
| 71 * value. | |
| 72 * - failure | |
| 73 * A function called if the validator function timeouts - fails to return | |
| 74 * the expected value in the given time. | |
| 75 * - name | |
| 76 * Name of test. This is used to generate the success and failure | |
| 77 * messages. | |
| 78 * - timeout | |
| 79 * Timeout for validator function, in milliseconds. Default is 5000 ms. | |
| 80 * - value | |
| 81 * The expected value. If this option is omitted then the |validator| | |
| 82 * function must return a trueish value. | |
| 83 * Each of the provided callback functions will receive two arguments: | |
| 84 * the |aOptions| object and the last value returned by |validator|. | |
