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)
