Hi, I've noticed this quite frequently where the following exception occurs,

I have the custom application in AppTest.jar. The exception occurs when I'm done executing AppTest.jar and re-execute it again.
As a temporary fix, I had to close autagent.exe and start it again before proceeding. This doesn't fix it since it will occur again sometime.
This occurs 1/10 occurrences at best and 10/10 at worst.

I'm suspecting it was caused by poor implementation. So here's my implementation of it:
private static AUTConfig config = AUTConfig.getInstance();

private static int runStatus = 0;

public static void main(String[] args) {
  try {
    config.init(args);
    AUTAgent autAgent = MakeR.createAUTAgent("localhost", 60000);
    autAgent.connect();

    AUTConfiguration configuration = new SwingAUTConfiguration("AppName", "AppID", "app.exe", "C:\\Program Files\\App", null);
    AUTIdentifier identifier = autAgent.startAUT(configuration);
    AUT aut = autAgent.getAUT(identifier, SwingComponents.getToolkitInformation());
    config.setAut(aut);

    // custom methods to execute test

  } catch(Exception e) {
    e.printStackTrace();
    runStatus = 1;
  } finally {
    autAgent.stopAUT(identifier);
    System.exit(runStatus);
  }
}

Hello,

please add aut.disconnect() and autAgent,disconnect() into the finally Block
finally {
    if(aut.isConnected()){
        aut.disconnect();
    }
    autAgent.stopAUT(identifier);
    autAgent.disconnect()
    System.exit(runStatus);
  }


I hope this makes it more reliably

best regards
Marvin

Hi,

I too have the same concern. Jubula does not close my swing application and hence i cannot have a sequential test execution. The code i tried to close the application is :

aut.disconnect();
autagent.stopAUT(autidentifier);
autagent.disconnect();

Also tried by putting some static wait but only to fail:(
Please let me know if there is any suggestion.

Hi i am facing the same issue. I am not able to connect the aut even for the first time.
Agent is connected and application is opened. but
AUTAgent autagent = null;
AUTConfiguration autconfiguration = null;
AUTIdentifier id ;
AUT aut = null;
autagent = MakeR.createAUTAgent("localhost",60000);
autagent.connect();
String autId = "app123";
String name = "app";
autconfiguration = new
SwingAUTConfiguration(name, autId,"XXXXXXX.bat", "C:\\Users\\XXXXX\\Documents\\Software\\XXXXXX",null);

id = autagent.startAUT(autconfiguration);
if(id!=null) {
aut = autagent.getAUT(id, SwingComponents.getToolkitInformation());
aut.connect();
}
it fails @ aut.connect();
pls help

Is there any more information? Is the AUT started? because if not something with the start is not correct.

best regards

Hi Marvin, I am too stuck here.
I tried your implementation but my application doesn't closes, I can see that disconnect happens though. This is Strange. Due to this, I am not able to run multiple test suites
