addAsync result doesn't preserve 'has 0 arguments' (.length == 0)
The result of the addAsync method is a function whose length is not 0, even if the input argument is 0. If a tested method expects a callback to take 0 arguments, and checks this fact, the addAsync method prevents the test from succeeding and has to be worked around:
private function testableAwaitCallback(func : Function) : Function {
var x:Function = this.addAsync(func);
if (func.length > 0) return x;
return function():* { return x(); };
}
This is fixed in AsUnit 4.0, where TestCase.addAsync() is delegated to Async.add(), which gets a wrapper function of correct length from here:
