Layers for zope.testing to simplify test setups
Project description
Testing Utilities
The most common use of this testing module is functional testing zope applications. It provides tools to setup layers which load the configuration ZCML as well as setting up wsgi_intercept in a layer.
This test is part of such a layer (setup in van.testing.tests.FunctionalLayer):
>>> from wsgi_intercept import WSGI_HTTPConnection as HTTPConnection >>> conn = HTTPConnection('localhost', 80)>>> conn.request('GET', '/') >>> r = conn.getresponse() >>> print r.read() # doctest: +ELLIPSIS {'HTTP_ACCEPT_ENCODING': 'identity', 'HTTP_HOST': 'localhost', 'PATH_INFO': '/', 'QUERY_STRING': '', 'REMOTE_ADDR': '127.0.0.1', 'REQUEST_METHOD': 'GET', 'SCRIPT_NAME': '', 'SERVER_NAME': 'localhost', 'SERVER_PORT': '80', 'SERVER_PROTOCOL': 'HTTP/1.1\r\n', 'wsgi.errors': <cStringIO.StringO object at ...>, 'wsgi.input': <cStringIO.StringI object at ...>, 'wsgi.multiprocess': 0, 'wsgi.multithread': 0, 'wsgi.run_once': 0, 'wsgi.url_scheme': 'http', 'wsgi.version': (1, 0)} Marker: MARKER
Layers
Some basic layers useful for making test setups.
>>> import os.path >>> from van.testing.layer import zcml_layer, null_layer
A zcml layer which sets up and tears down a zcml test harness (but is much simpler than that provided with zope.app.functional):
>>> class ZCMLLayer: ... zcml = os.path.join(os.path.dirname(__file__), 'ftesting.zcml') >>> zcml_layer(ZCMLLayer)
Some default layers are provided for use with zope.testing, a “null” layer that specifically does nothing. This is useful for layers which inherit from other layers but where you don’t want setup/teardown functions run twice (is this a zope.testing bug?):
>>> class ExampleNullLayer(ZCMLLayer): ... pass >>> null_layer(ExampleNullLayer)
Changes
2.0.0 (2009-04-01)
Remove dependencies by using zope.configuration.xmlconfig to setup zcml rather than zope.app.appsetup. This leaves out some security configuration but the win from less dependencies is massive. In my tests, no tests had any issues with this.
Add a wsgi_intercept layer and a functional_layer that combines both zcml and wsgi_intercept layer.
1.0.0 (2008-11-21)
