Gocept-selenium

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

- Selenium updated to version 3.

- ``selenese_pattern_equals()`` in `wd_selenese.py` now returns a bool.

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

- Drop support for Zope 2.

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

- Fix ``wd_selense.Selenese.selectFrame('index=0')`` to forward the index as
number to the underlying WebDriver so it is actually treated as an index.

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

- Support selenium versions >= 2.53.
https://bitbucket.org/gocept/gocept.selenium/issues/12

- Require a selenium version < 3.0 as this version removed the support for
Selenium RC.

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

- Drop support for:

- ``zope.app.testing`` (extras_require: [ztk])

- ``Testing.ZopeTestCase`` (extras_require: [zope2])

- ``plone.app.testing`` (extras_require: [test_plonetestingz2])

- ``Products.PloneTestCase`` (extras_require: [plonetestcase])

- Remove the empty ``script`` extras_require.

- Drop support for Python 2.4, 2.5, 2.6. Now only supporting Python 2.7.

- Currently only supporting a ``selenium`` version < 2.53 as this version
breaks using a custom Firefox.
See https://github.com/SeleniumHQ/selenium/issues/1965

- Add ``.wd_selense.Selenese.selectParentFrame()`` to select the
parent of a frame or an iframe.

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

- Fix using a local Firefox using ``GOCEPT_WEBDRIVER_REMOTE=False`` as the
environment setting.
