+ *        A validator function that should return the expected value. This is
+ *        called every few milliseconds to check if the result is the expected
+ *        one. When the returned result is the expected one, then the |success|
+ *        function is called and polling stops. If |validator| never returns
+ *        the expected value, then polling timeouts after several tries and
+ *        a failure is recorded - the given |failure| function is invoked.
+ *        - success
+ *        A function called when the validator function returns the expected
+ *        value.
+ *        - failure
+ *        A function called if the validator function timeouts - fails to return
+ *        the expected value in the given time.
+ *        - name
+ *        Name of test. This is used to generate the success and failure
+ *        messages.
+ *        - timeout
+ *        Timeout for validator function, in milliseconds. Default is 5000 ms.
+ *        - value
+ *        The expected value. If this option is omitted then the |validator|
+ *        function must return a trueish value.
+ *        Each of the provided callback functions will receive two arguments:
+ *        the |options| object and the last value returned by |validator|.
