Thank you very much guys.

I think We will be applying something similar to Lawrence’s approach for the moment as a workaround.

However, we are looking forward to seeing Matt’s implementation with FlexUnit under Flex 1.5.

Matt,

If you don’t mind, would you be able to give some information about your design?

Regards

Hi Cumhur,

indees the problem is Flash Player's single threaded engine. If you setup a for or while loop after calling a remote method, the player "blocks" and is not able to process responses that comes in from the remote method.

To process the result of a async method invokation, you'll have to use the result/fault events of your service tag, i.e.

public function testEndToEnd() {

_root.logonWindow.username.text = "tcfeu";

_root.logonWindow.password.text = "1";

EventBroadcaster.getInstance().broadcastEvent("SomeCommand");

}

after the event has been broadcasted and SomeCommand executed, some time later the defined onResult event handler will be invoked with the service results (if SomeCommand implements Responder then SomeCommand.onResult() will be invoked). If an error occured, the onFault method will be called.

Hope that helps,

Dirk.

Cumhur,

I ran into this as well this week. After some tinkering, I came upon

a solution. I extendedthe FlexUnit TestCase class to make an

AsyncTestCase class from which my own test cases that make

asynchronous calls can inherit. In my case, I was testing my

services like this:

public function testSomeServiceOperation() {

var service : Object = Services.getInstance

().getService("someService");

var pendingCall = service.someOperation();

pendingCall.resultHandler = Delegate.create(this,

CheckResult);

pendingCall.faultHandler = Delegate.create(this,

ServiceFailed);

}

public function CheckResult(result : Object) {

...

asyncAddFailure("", "The test failed.");

...

}

public function ServiceFailed(result : Object) {

asyncAddFailure("", "The service threw a fault.");

}

From AsyncTestCase.as:

public function asyncAddFailure(userMessage : String,

message : String) : Void {

if (userMessage.length > 0) {

userMessage = userMessage + " - ";

}

mx.core.Application.application.testRunner.runner.treeDataPro

vider.addFailure(this,new Error(userMessage + message));

mx.core.Application.application.testRunner.testsTree.dispatch

Event({type:"change"});

}

Note that I gave my TestRunner the id of 'testRunner'.

This is probably not the best solution and I would love to see a

more elegant one. So if anyone has solved this more elegantly, I

would be interested aswell. Perhaps there can be a tighter

integration between Cairngorm and FlexUnit.

Hope this helps (for what it is),
