actionscript 3 - Bug or Expected behavior for Async FlexUnit Test? -

i have been working on how handle inherited flexunit test beginning fail on faster server builds. mymockservice not getting prepared before unit test begins run. using flexunit , mockolate.

<failure      message="a proxy com.something.somemock.service::mymockservice has not been prepared yet"      type="com.something.somemock.myasynctest">argumenterror: proxy com.something.somemock.service::mymockservice has not been prepared yet.     //... (lots removed here) </failure> 

generic imports being used:

import flash.events.event; import flexunit.framework.assert; import mockolate.nice; import mockolate.prepare; import mockolate.stub; import mockolate.verify; import org.flexunit.async.async; import flash.utils.timer; import flash.events.timerevent; 

here's stub of code. (i think) important parts there gist.

public class myasynctest {      [before(async)]     public function preparemockobjects():void     {         async.proceedonevent(this, prepare(mymockservice), event.complete);     }      [test(async)]     public function testexecute():void     {          var service:mymockservice = nice(mymockservice);         verify(service).method("runsomething").args(argumentbuilder).once();      } } 

after doing lot of work changing timeouts , adding sleep methods (all useless in battling error) have introduced 1 more test flexunit test class contains delay. ordered tests , finding test passes every time. (this good) hate putting test in 3 second delay need prepare finish.

here's code stub visuals:

public class myasynctest {        protected function makemesleep(howlongms:int):void     {         //timer code sleep     }      [before(async)]     public function preparemockobjects():void     {         async.proceedonevent(this, prepare(mymockservice), event.complete);     }      [test(async, order=1)]     public function delaythenexttest():void     {         var haspaused:boolean = makemesleep(3000);         assert.asserttrue("this silly delay allow service prepare", true);     }      [test(async, order=2)]     public function testexecute():void     {         var service:mymockservice = nice(mymockservice);         verify(service).method("runsomething").args(argumentbuilder).once();             } } 

i'm glad have test build should, feels dirty. has been assumption [test] block not run until [before] block has finished doesn't seem case in testing condition. guess 1 important take away folks me whether test in poor style way mock service being prepared, , better way avoid adding "sleep" test buy time? (poor style in , of imho)

thanks input in advance.

i have run similar issues mockolate, , seem remember reading answer drew mentioned aware exist.

i have found rules reliable async tests, , using them makes code more readable, well. declare both mockolaterule , desired mock objects member variable (must public metadata picked correctly, , make sure instantiate rule!), use mock() nice() otherwise.

[rule] public var myrule:mockolaterule = new mockolaterule();  [mock] public var myservice:myservice;  [before] public function setup():void {     myservice = mock(myservice); }  [test] public function test():void {     assertnotnull(myservice); }
