Re: [appengine-java] Re: How do I run DeferredTasks in a Unit Test

[Brendan Doherty]

getBodyAsBytes() solves the problem. 

The following code will run each of the queued DeferredTasks from within a 
JUnit test.


    String queueName = QueueFactory.getDefaultQueue().getQueueName();

    ServletRunner sr = new ServletRunner();
    sr.registerServlet(
        "/_ah/queue/__deferred__",
       
 
com.google.apphosting.utils.servlet.DeferredTaskServlet.class.getCanonicalName());
 
   

    LocalTaskQueue localTaskQueue = 
LocalTaskQueueTestConfig.getLocalTaskQueue();
    
    ServletUnitClient client = sr.newClient();

    while (!getQueue().getTaskInfo().isEmpty()) {

      TaskStateInfo taskInfo = getQueue().getTaskInfo().iterator().next();

      byte[] taskBody = taskInfo.getBodyAsBytes();

      String taskName = taskInfo.getTaskName();

      WebRequest request = new 
PostMethodWebRequest("http:/_ah/queue/__deferred__",
          new ByteArrayInputStream(taskBody), 
"application/x-binary-app-engine-java-runnable-task");
      
      request.setHeaderField("X-AppEngine-QueueName", queueName);
      
      try {
        client.sendRequest(request);
      } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
      } catch (SAXException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
      } finally {      
        localTaskQueue.deleteTask(queueName, taskName);
      }
    }
    localTaskQueue.flushQueue(queueName);
