Hi Salvatore,
Thanks! I'm working on a python class to easily publishing process based
on PyWPS and QGIS-Processing.
I have updated my script exemple :
======================
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import sys, os
import inspect
#first qgis
from qgis.core import *
#next PyQt4
from PyQt4.QtCore import *
from PyQt4.QtGui import *
# init QApplication for processing and set the customSettingFolder
#a = QApplication( sys.argv )
QgsApplication( sys.argv, False, "/my/custom/path" )
# supply path to where is your qgis installed
QgsApplication.setPrefixPath("/my/build", True)
# load providers
QgsApplication.initQgis()
p = QgsProject.instance()
p.read( QFileInfo( "/my/project.qgs" ) )
print p.title()
mlr = QgsMapLayerRegistry.instance()
qa = QApplication( sys.argv )
from processing.core.Processing import Processing
cmd_folder = os.path.split(inspect.getfile(inspect.currentframe()))[0]
if cmd_folder not in sys.path:
sys.path.insert(0, cmd_folder)
Processing.initialize()
from processing.tools import *
#general.alglist( 'znt' )
#general.alghelp( 'modeler:znt' )
paramalg = []
print "runalg start"
general.runalg( 'process:identifier', *paramalg )
print "runalg end"
# quit
QgsApplication.exitQgis()
#a.exit()
QApplication.exit()
======================

René-Luc D'Hont

Hi,
I just tested it and works wonderfully!
I also have tried it as web process for PyWPS and works very well!
Thanks a lot for this!
Best Regards,

Hi dev,
I just created a pull request to run QGIS-Processing headless.
I have tested it with a qgis and a modeler algorithm.

Review and comments are welcome
To test QGIS Processing algorithm headlessly, you can use this
python code
