Plone-testing

------------------

Bug fixes:


- Fixed test for 'Connection refused' which could be 'Connection reset'.
[maurits] (59)

------------------

Breaking changes:

- ``plone.testing.z2`` is now a BBB shim for ``plone.testing.zope``,
thus it switches the tests to use WSGI.
If you absolutely want to keep using ZServer please import from ``plone.testing.zserver``.

- ``plone.testing.z2`` now only contains a no-op FTPServer layer because FTP is not supported by WSGI.
If you really need it, import it from ``plone.testing.zserver`` but this will not work on Python 3.

- Default to picking a dynamical port for ZServer layers instead of a static
default port.
[Rotonen]

New features:

- Make ``ZServer`` an optional dependency.

- Add support for Python 3.6.

Bug fixes:

- Explicitly depend on ZServer on the z2 extra.

Breaking changes:

- Default to picking a dynamical port for ZServer layers instead of a static
default port.
[Rotonen]

Bug fixes:

- Pinned ZODB to < 5.4.0 for testing to avoid flaky doctest layer teardowns.
[Rotonen]

- Loosened doctest assertions to keep up with Zope-side changes.
[Rotonen]

- Fix most of the code smells Jenkins complains about.

- Fix the Zope exception hook when using the ZServer layer.

- Fix teardown of the ``plone.testing.security.Checkers`` layer.
It was not properly restoring zope.security's ``_checkers`` dict.

------------------

- Breaking changes:

+ Only support ``Zope >= 4``, no longer support ``Zope2``.
+ Drop support for Python 2.6.

- No longer use deprecated import for getSite/setSite.
[jensens]

- Update code to follow Plone styleguide.
[gforcada]

------------------

- Do not break on import of ``plone.testing.z2`` when using `zope.testbrowser` >= 5.0 which no longer depends on `mechanize`.

----------------

- Fix for ZODB 5: Abort transaction before DB close.
[jensens, jimfulton]

- Remove BBB code and imports for Zope < 2.13.
[thet]

- Fix issue, which prevented using layered-helper on Python 3.
[datakurre]

- Fix ``.z2.Startup.setUpZCML()`` to be compatible with Zope >= 4.0a2.
[icemac]

- Fix version pins on the package itself to be able to run the tests.
