Testing

Testing is nice and useful. Here is how you can test your cornices applications.

Let’s suppose you have this service definition:

from pyramid.config import Configurator

from cornice import Service
from cornice.tests import CatchErrors

service = Service(name="service", path="/service")


def has_payed(request):
    if not 'paid' in request.GET:
        request.errors.add('body', 'paid', 'You must pay!')


@service.get(validator=has_payed)
def get1(request):
    return {"test": "succeeded"}


def includeme(config):
    config.include("cornice")
    config.scan("absolute.path.to.this.service")


def main(global_config, **settings):
    config = Configurator(settings={})
    config.include(includeme)
    return CatchErrors(config.make_wsgi_app())

We have done three things here:

• setup a service, using the Service class and define our services with it
• register the app and cornice to pyramid in the includeme function
• define a main function to be used in tests

To test this service, we will use webtest, and the TestApp class:

from webtest import TestApp
import unittest

from yourapp import main

class TestYourApp(unittest.TestCase):

    def test_case(self):
        app = TestApp(main({}))
        app.get('/service', status=400)
