-------- - Add ``setUp`` and ``tearDown`` functions to the ``repoze.bfg.testing`` module. Using ``setUp`` in a test setup and ``tearDown`` in a test teardown is now the recommended way to do component registry setup and teardown. Previously, it was recommended that a single function named ``repoze.bfg.testing.cleanUp`` be called in both the test setup and tear down. ``repoze.bfg.testing.cleanUp`` still exists (and will exist "forever" due to its widespread use); it is now just an alias for ``repoze.bfg.testing.setUp`` and is nominally deprecated. - The BFG component registry is now available in view and event subscriber code as an attribute of the request ie. ``request.registry``. This fact is currently undocumented except for this note, because BFG developers never need to interact with the registry directly anywhere else. - The BFG component registry now inherits from ``dict``, meaning that it can optionally be used as a simple dictionary. *Component* registrations performed against it via e.g. ``registerUtility``, ``registerAdapter``, and similar API methods are kept in a completely separate namespace than its dict members, so using the its component API methods won't effect the keys and values in the dictionary namespace. Likewise, though the component registry "happens to be" a dictionary, use of mutating dictionary methods such as ``__setitem__`` will have no influence on any component registrations made against it. In other words, the registry object you obtain via e.g. ``repoze.bfg.threadlocal.get_current_registry`` or ``request.registry`` happens to be both a component registry and a dictionary, but using its component-registry API won't impact data added to it via its dictionary API and vice versa. This is a forward compatibility move based on the goals of "marco". Documentation ------------- - Various tutorial test modules updated to use ``repoze.bfg.testing.setUp`` and ``repoze.bfg.testing.tearDown`` methods in order to encourage this as best practice going forward. Backwards Incompatibilities --------------------------- - Importing ``getSiteManager`` and ``get_registry`` from ``repoze.bfg.registry`` is no longer supported. These imports were deprecated in repoze.bfg 1.0. Import of ``getSiteManager`` should be done as ``from zope.component import getSiteManager``. Import of ``get_registry`` should be done as ``from repoze.bfg.threadlocal import get_current_registry``. This was done to prevent a circular import dependency. - Code bases which alternately invoke both ``zope.testing.cleanup.cleanUp`` and ``repoze.bfg.testing.cleanUp`` (treating them equivalently, using them interchangeably) in the setUp/tearDown of unit tests will begin to experience test failures due to lack of test isolation. The "right" mechanism is ``repoze.bfg.testing.cleanUp`` (or the combination of ``repoze.bfg.testing.setUp`` and ``repoze.bfg.testing.tearDown``). but a good number of legacy codebases will use ``zope.testing.cleanup.cleanUp`` instead. We support ``zope.testing.cleanup.cleanUp`` but not in combination with ``repoze.bfg.testing.cleanUp`` in the same codebase. You should use one or the other test cleanup function in a single codebase, but not both. Internal -------- - Created new ``repoze.bfg.configuration`` module which assumes responsibilities previously held by the ``repoze.bfg.registry`` and ``repoze.bfg.router`` modules (avoid a circular import dependency). - The result of the ``zope.component.getSiteManager`` function in unit tests set up with ``repoze.bfg.testing.cleanUp`` or ``repoze.bfg.testing.setUp`` will be an instance of ``repoze.bfg.registry.Registry`` instead of the global ``zope.component.globalregistry.base`` registry. This also means that the threadlocal ZCA API functions such as ``getAdapter`` and ``getUtility`` as well as internal BFG machinery (such as ``model_url`` and ``route_url``) will consult this registry within unit tests. This is a forward compatibility move based on the goals of "marco". - Removed ``repoze.bfg.testing.addCleanUp`` function and associated module-scope globals. This was never an API.
2009-09-16- The ``repoze.bfg.testing.registerDummyRenderer`` API has beenChris McDonough
deprecated in favor of ``repoze.bfg.testing.registerTemplateRenderer``. A deprecation warning is *not* issued at import time for the former name; it will exist "forever". - The ``repoze.bfg.templating.renderer_from_cache`` function has been moved to ``repoze.bfg.renderer.template_renderer_factory``. This was never an API, but code in the wild was spotted that used it. A deprecation warning is issued at import time for the former. - Better error message when a wrapper view returns None.
2009-07-05Spellcheck.Chris McDonough
2009-05-05- Applications which rely on ``zope.testing.cleanup.cleanUp` in unitChris McDonough
tests can still use that function indefinitely. However, for maximum forward compatibility, they should import ``cleanUp`` from ``repoze.bfg.testing`` instead of from ``zope.testing.cleanup``. The BFG paster templates and docs have been changed to use this function instead of the ``zope.testing.cleanup`` version.
2009-01-07- Add a method named ``assert_`` to the DummyTemplateRenderer. ThisChris McDonough
method accepts keyword arguments. Each key/value pair in the keyword arguments causes an assertion to be made that the renderer received this key with a value equal to the asserted value. - Projects generated by the paster templates now use the ``DummyTemplateRenderer.assert_`` method in their view tests.
2008-12-21 Backwards Incompatibilities (Major)Chris McDonough
- Rather than prepare the "stock" implementations of the ZCML directives from the ``zope.configuration`` package for use under :mod:`repoze.bfg`, :mod:`repoze.bfg` now makes available the implementations of directives from the ``repoze.zcml`` package (see http://static.repoze.org/zcmldocs). As a result, the :mod:`repoze.bfg` package now depends on the ``repoze.zcml`` package, and no longer depends directly on the ``zope.component``, ``zope.configuration``, ``zope.interface``, or ``zope.proxy`` packages. The primary reason for this change is to enable us to eventually reduce the number of inappropriate :mod:`repoze.bfg` Zope package dependencies, as well as to shed features of dependent package directives that don't make sense for :mod:`repoze.bfg`. Note that currently the set of requirements necessary to use bfg has not changed. This is due to inappropriate Zope package requirements in ``chameleon.zpt``, which will hopefully be remedied soon. - BFG applications written prior to this release which expect the "stock" ``zope.component`` ZCML directive implementations (e.g. ``adapter``, ``subscriber``, or ``utility``) to function now must either 1) include the ``meta.zcml`` file from ``zope.component`` manually (e.g. ``<include package="zope.component" file="meta.zcml">``) and include the ``zope.security`` package as an ``install_requires`` dependency or 2) change the ZCML in their applications to use the declarations from `repoze.zcml <http://static.repoze.org/zcmldocs/>`_ instead of the stock declarations. ``repoze.zcml`` only makes available the ``adapter``, ``subscriber`` and ``utility`` directives. - The ``http://namespaces.repoze.org/bfg`` XML namespace is now the default XML namespace in ZCML for paster-generated applications. - The copies of BFG's ``meta.zcml`` and ``configure.zcml`` were removed from the root of the ``repoze.bfg`` package. In 0.3.6, a new package named ``repoze.bfg.includes`` was added, which contains the "correct" copies of these ZCML files; the ones that were removed were for backwards compatibility purposes. Other - The minimum requirement for ``chameleon.core`` is now 1.0b13. The minimum requirement for ``chameleon.zpt`` is now 1.0b7. The minimum requirement for ``chameleon.genshi`` is now 1.0b2.

2008-11-07 FeaturesChris McDonough
- Added a ``repoze.bfg.testing`` module to attempt to make it slightly easier to write unittest-based automated tests of BFG applications. Information about this class is in the documentation. - The default template renderer now supports testing better by looking for ``ITestingTemplateRenderer`` using a relative pathname. This is exposed indirectly through the API named ``registerTemplate`` in ``repoze.bfg.testing``. Deprecations - The names ``repoze.bfg.interfaces.ITemplate`` , ``repoze.bfg.interfaces.ITemplateFactory`` and ``repoze.bfg.interfaces.INodeTemplate`` have been deprecated. These should now be imported as ``repoze.bfg.interfaces.ITemplateRenderer`` and ``repoze.bfg.interfaces.ITemplateRendererFactory``, and ``INodeTemplateRenderer`` respectively. - The name ``repoze.bfg.chameleon_zpt.ZPTTemplateFactory`` is deprecated. Use ``repoze.bfg.chameleon_zpt.ZPTTemplateRenderer``. - The name ``repoze.bfg.chameleon_genshi.GenshiTemplateFactory`` is deprecated. Use ``repoze.bfg.chameleon_genshi.GenshiTemplateRenderer``. - The name ``repoze.bfg.xslt.XSLTemplateFactory`` is deprecated. Use ``repoze.bfg.xslt.XSLTemplateRenderer``.
