Cumhur,
I ran into this as well this week. After some tinkering, I came upon
a solution. I extended the 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 as well. Perhaps there can be a tighter
integration between Cairngorm and FlexUnit.
Hope this helps (for what it is),
Lawrence
