* Tester function.

* - action:

* - cancelBeforeInput:
* true if preventDefault() of "beforeinput" should be
* called.
* @param aFunc Function to run test.
* @param aExpected Object which has:
* - value [optional]:
* Set string value if the test needs to check value of
* aElement.
* Set undefined if the test does not need to check it.
* - valueForCanceled [optional]:
* Set string value if canceling "beforeinput" does not
* keep the value before calling aFunc.
* - beforeInputEvent [optional]:
* Set object which has `cancelable`, `inputType` and `data`
* if a "beforeinput" event should be fired.
* Set null if "beforeinput" event shouldn't be fired.
* - inputEvent [optional]:
* Set object which has `inputType` and `data` if an "input" event
* should be fired if aTestData.cancelBeforeInput is not true.
* Set null if "input" event shouldn't be fired.
* Note that if expected "beforeinput" event is cancelable and
* aTestData.cancelBeforeInput is true, this is ignored.
