- any method of the :class:`pyramid.config.Configurator`
object returned by this function.
- the :func:`pyramid.threadlocal.get_current_registry` or

If you use the ``get_current_*`` functions (or call :app:`Pyramid` code
that uses these functions) without calling ``setUp``,
:func:`pyramid.threadlocal.get_current_registry` will return a *global*
:term:`application registry`, which may cause unit tests to not be
isolated with respect to registrations they perform.
If the ``registry`` argument is ``None``, a new empty
:term:`application registry` will be created (an instance of the
:class:`pyramid.registry.Registry` class). If the ``registry``
argument is not ``None``, the value passed in should be an
instance of the :class:`pyramid.registry.Registry` class or a
suitable testing analogue.

:func:`pyramid.threadlocal.get_current_request` function will
be the passed (or constructed) registry until

If the ``hook_zca`` argument is ``True``, ``setUp`` will attempt
to perform the operation ``zope.component.getSiteManager.sethook(

the :term:`Zope Component Architecture` global API

constructed by ``setUp`` as the value it returns from
:func:`zope.component.getSiteManager`. If the
:mod:`zope.component` package cannot be imported, or if
``hook_zca`` is ``False``, the hook will not be set.
If ``settings`` is not None, it must be a dictionary representing the
values passed to a Configurator as its ``settings=`` argument.
This function returns an instance of the
:class:`pyramid.config.Configurator` class, which can be
used for further configuration to set up an environment suitable
for a unit or integration test. The ``registry`` attribute
attached to the Configurator instance represents the 'current'
