[Zope-dev] [PATCH] zope.app.testing: Use doctest instead of deprecated zope.testing.doctest

Hello, Recent versions of zope.testing deprecate the zope.testing.doctest module in favour of the standard library's doctest module. zope.app.testing currently uses zope.testing.doctest for its tests and to provide its functional testing features. This patch changes it to use standard library doctest. The patch also deletes a repeated import line from zope.app.testing.functional, caught thanks to pyflakes. jml
