def test_requestapi():
>>> from lp.app.browser.tales import IRequestAPI, RequestAPI
>>> from lp.registry.interfaces.person import IPerson
>>> from zope.interface.verify import verifyObject
>>> class FakePrincipal:
...     def __conform__(self, protocol):
...         if protocol is IPerson:
...             return "This is a person"
...
>>> class FakeApplicationRequest:
...    principal = FakePrincipal()
...    def getURL(self):
...        return 'http://launchpad.dev/'
...

Let's make a fake request, where request.principal is a FakePrincipal object. We can use a class or an instance here. It really doesn't matter.

>>> request = FakeApplicationRequest()
>>> adapter = RequestAPI(request)
>>> verifyObject(IRequestAPI, adapter)
True
>>> adapter.person
'This is a person'
def test_cookie_scope():

The 'request/lp:cookie_scope' TALES expression returns a string that represents the scope parameters necessary for a cookie to be available for the entire Launchpad site. It takes into account the request URL and the cookie_domains setting in launchpad.conf.

>>> from lp.app.browser.tales import RequestAPI
>>> def cookie_scope(url):
...     class FakeRequest:
...         def getURL(self):
...             return url
...     return RequestAPI(FakeRequest()).cookie_scope

The cookie scope will use the secure attribute if the request was secure:

>>> print cookie_scope('http://launchpad.net/')
; Path=/; Domain=.launchpad.net
>>> print cookie_scope('https://launchpad.net/')
; Path=/; Secure; Domain=.launchpad.net

The domain parameter is omitted for domains that appear to be separate from a Launchpad instance:

>>> print cookie_scope('https://example.com/')
; Path=/; Secure
def test_dbschemaapi():
>>> from lp.app.browser.tales import DBSchemaAPI
>>> from lp.code.enums import BranchType

The syntax to get the title is: number/lp:DBSchemaClass

>>> (str(DBSchemaAPI(1).traverse('BranchType', []))
...  == BranchType.HOSTED.title)
True

Using an inappropriate number should give a KeyError.

>>> DBSchemaAPI(99).traverse('BranchType', [])
Traceback (most recent call last):
...
KeyError: 99

Using a dbschema name that doesn't exist should give a LocationError

>>> DBSchemaAPI(99).traverse('NotADBSchema', [])
Traceback (most recent call last):
...
LocationError: 'NotADBSchema'
