Testing with chameleon templates fails

# test02/__init__.py

from pyramid.config import Configurator

from pyramid_zodbconn import get_connection

from .models import appmaker

def root_factory(request):

    conn = get_connection(request)

    return appmaker(conn.root())

def main(global_config, **settings):

    """ This function returns a Pyramid WSGI application.

    """

    config = Configurator(root_factory=root_factory, settings=settings)

    settings = config.get_settings()

    settings['tm.manager_hook'] = 'pyramid_tm.explicit_manager'

    config.include('pyramid_chameleon')  # included also in .ini

    config.add_static_view('static', 'static', cache_max_age=3600)

    config.scan()

    return config.make_wsgi_app()

My test is quite simple

# test02/tests.py

import unittest

from pyramid import testing

from webtest import TestApp

from pyramid.paster import get_app

class FuncTests(unittest.TestCase):

    def setUp(self):

        app = get_app('development.ini')

        self.testApp = TestApp(app)

    def tearDown(self):

        testing.tearDown()

    def test_root(self):

        r = self.testApp.get('/')

# development.ini

[app:main]

use = egg:test02

pyramid.reload_templates = true

pyramid.debug_authorization = false

pyramid.debug_notfound = false

pyramid.debug_routematch = false

pyramid.default_locale_name = en

pyramid.includes =

    pyramid_debugtoolbar

    pyramid_zodbconn

    pyramid_tm

    pyramid_chameleon

The view works fine but fails in testing.

# test02/views.py

from pyramid.view import view_config

from .models import MyModel

@view_config(context=MyModel, renderer='templates/mytemplate.pt')

def my_view(request):

    return {'project': 'test02'}

However if I run pytest test02/tests.py I get this error

self = <pkg_resources.NullProvider object at 0x7f4aae5660a0>, path = '/home/silviud/PROGS/test02/test02/templates/mytemplate.pt'

    def _has(self, path):

        )

E       NotImplementedError: Can't perform this operation for unregistered loader type

I don't know why you have this issue. However, the scaffolds generated from pcreate have been deprecated since Pyramid 1.8 and will be removed in Pyramid 2.0. Instead use its replacement pyramid-cookiecutter-starter.

Hi Steve,

Thanks for your answer - I found that this happens _only_ with pytest.

Adding this to test file

if __name__ == '__main__':

    unittest.main(verbosity=2)

And run it as python test02/test.py collects the tests and its fine.

I guess it has to do with the way pytest makes the import of the package. I didn't find much yet ... testing with pdb.

I found the problem. The new cookiecutter template adds into pytest.ini a different pattern than the old.

 [pytest]

 testpaths = tests

-python_files = *.py

+python_files = test*.py

thanks again,
