Question

I’m using play 1.2.4 and I’m trying to set up a unit test to test a job.
My job runs at every 2 second and changes the status of certain objects based on some conditions. This is what I use to do this.

@Every("2s")
public class GameScheduler extends Job {
    public void doJob(){
        //Fetch of object from db and status change based on conditions happens here
    }
}

Now in my unit test, I setup those conditions but I want the test to wait say 3 seconds before fetching one of the setup objects and do an assert Equals on its status to see if the job… well did it’s job.

If I use

pause(3000);

or something like

try {
    Thread.sleep(3000);
} catch (InterruptedException e) {
    e.printStackTrace();
}

The test stops but the job also stops. It seems like the job and the test are on the same thread. Is there a way to pause the test without stopping the job? Something like the await() method in the controller

Answer 1

You don’t need to test the scheduler because it is supposed to work (since the framework is handling it). What you need is just test if the doJob method is doing its work. So, just write a test like this:

GameScheduler job = new GameScheduler();
job.doJob();

// assert whatever you want here
