How to test the attributes added by add_request_method of pyramid

pyramid add_request_method

You can add the property of request with the directive add_request_method of pyramid. (In the past, there was a directive called add_request_property, but it became deprecated in haste)

Effect of add_request_method

document: http://docs.pylonsproject.org/projects/pyramid/en/latest/api/config.html#pyramid.config.Configurator.add_request_method

There are two options to keep in mind:

--reify --Add an attribute to request. The added attributes are cached --property --Add an attribute to request. The added attribute is calculated each time

If nothing is added, it will be added as a method. (Also, if verify = True, it is automatically added as property)

## configuration
def includeme(config):
    ## request.get_foo()Can be called as
    config.add_request_method(get_foo, "get_foo")

    ## request.Can be accessed as foo
    config.add_request_method(get_foo2, "foo", reify=True)
    config.add_request_method(get_foo2, "foo", property=True)

Test of attributes added by add_request_method

test. If it's a unit test, you can use mock for text. Somehow it can be done by using dummy. A story about what to do during an integration test.

Where the directive defined by add_request_method is valid.

Let's look at the pyramid code. The answer is in pyramid / router.py. Roughly speaking, we can see the following.

--add_request_method stores an interface called IRequestExtensions in the key --Set with pyramid.request.Request._set_extensions ()

An example of how to write a test

An example of how to write an integration test with reference to the above This time, set request.foo. Just check if you can get it with request.foo.

# -*- coding:utf-8 -*-
import unittest


## definition

foo = object()

def get_foo(request):
    return foo

def includeme(config):
    config.add_request_method(get_foo, "foo", reify=True)


## test

class Tests(unittest.TestCase):
    def _makeOne(self, config, path="/"):
        from pyramid.request import Request
        from pyramid.interfaces import IRequestExtensions

        request = Request.blank(path)
        extensions = config.registry.getUtility(IRequestExtensions)
        request.registry = config.registry
        request._set_extensions(extensions)
        return request

    def test_it(self):
        from pyramid.testing import testConfig

        with testConfig() as config:
            config.include(includeme)

            ### request time
            request = self._makeOne(config, path="/")
            self.assertEqual(request.foo, foo)
