=== Testing a service with virtual robot

A service can be tested in the virtual robot settings.

* prepare an app with the service to test - you may start with the examples below or use the ''templater'' tool [https://github.com/pepperhacking/robot-jumpstarter#template-python-service robot-jumpstarter] (use a ''new name'' for your service):
  {{{
ssh aurora
cd /nlp/projekty/pepper/web/robot-jumpstarter
python jumpstart.py python-service tweety-service TweetyService
cp -a output/tweety-service ~/pepper/
}}}
  Here `tweety-service` is the directory name of the application (and the app name), `TweetyService` is the API name of your service as it will be called from Python.[[br]]
* copy the directory with the service app (e.g. `~/pepper/tweety-service`) to your computer, where you run Choregraphe. All the following steps are done on this computer, ''not remotely'' via SSH.
* start Choregraphe and [../Introduction#virtualrobot run the virtual robot]
* find out the ''port number'' of your virtual robot: click 
  Here the virtual robot's address is `localhost:34121`
* run your service in the virtual robot (Choregraphe must still be running, of course):
  {{{
cd ~/pepper/tweety-service/app
python scripts/tweetyservice.py --qi-url localhost:34121
}}}
  The output should look like:
  {{{
[I] 1584373059.579170 4749 qimessaging.session: Session listener created on tcp://0.0.0.0:0
[I] 1584373059.579385 4749 qimessaging.transportserver: TransportServer will listen on: tcp://192.168.1.2:36873
[I] 1584373059.579394 4749 qimessaging.transportserver: TransportServer will listen on: tcp://127.0.0.1:36873
}}}
* now you can ''communicate'' with your running service in the same way as with all other API services on the real robot:
  * use `^call(TweetyService.get())` in a dialog
  * direct call in a Python Box code:
    {{{#!python
def __init__(self):
   self.tweety = ALProxy('TweetyService')

def onInput_onStart(self):
    self.tts.say("číslo {}".format(self.tweety.get()))
    self.onStopped() #activate the output of the box
}}}
  * use the [http://doc.aldebaran.com/2-5/dev/libqi/guide/qicli.html qicli] command line tool:
    {{{
alias qicli='"/opt/Softbank Robotics/Choregraphe Suite 2.5/bin/qicli" --qi-url localhost:34121'
qicli info TweetyService
call TweetyService.get
call TweetyService.set 2
call TweetyService.get
}}}
    with the output
    {{{
099 [TweetyService]
