"""Set up hypothesis."""
Various API changes and other improvements. * Deprecate ``bidict.OVERWRITE`` and ``bidict.IGNORE``. A :class:`UserWarning` will now be emitted if these are used. :attr:`bidict.DROP_OLD` and :attr:`bidict.DROP_NEW` should be used instead. * Rename ``DuplicationPolicy`` to :class:`~bidict.OnDupAction` (and implement it via an :class:`~enum.Enum`). A :class:`~bidict.OnDupAction` may be one of :attr:`~bidict.RAISE`, :attr:`~bidict.DROP_OLD`, or :attr:`~bidict.DROP_NEW`. * Expose the new :class:`~bidict.OnDup` class, a named (*key*, *val*, *kv*) tuple of :class:`~bidict.OnDupAction`\s that should be taken upon encountering the 3 kinds of duplication that can occur. * Provide the :attr:`~bidict.ON_DUP_DEFAULT`, :attr:`~bidict.ON_DUP_RAISE`, and :attr:`~bidict.ON_DUP_DROP_OLD` :class:`~bidict.OnDup` convenience instances. * Deprecate the ``on_dup_key``, ``on_dup_val``, and ``on_dup_kv`` arguments of :meth:`~bidict.bidict.put` and :meth:`~bidict.bidict.putall`. A :class:`UserWarning` will now be emitted if these are used. They have been subsumed by the new *on_dup* argument, which takes an :class:`~bidict.OnDup` instance. Use it like this: ``bi.put(1, 2, OnDup(key=DROP_NEW))``. Or better yet, pass one of the ``ON_DUP_*`` convenience instances instead if possible. See the updated :ref:`basic-usage:Values Must Be Unique` docs for more info. * Deprecate the ``on_dup_key``, ``on_dup_val``, and ``on_dup_kv`` bidict class attributes. A :class:`UserWarning` will now be emitted if these are used. They have been subsumed by the new :attr:`~bidict.bidict.on_dup` class attribute, which takes an :class:`~bidict.OnDup` instance. See the updated :doc:`extending` docs for example usage. * Move :meth:`bidict.BidictBase.values` to :meth:`bidict.BidirectionalMapping.values`, since the implementation is generic. * No longer use ``__all__`` in ``bidict/__init__.py``. * Cap max_size rather than disabling health checks and deadline as a less heavyhanded way to improve hypothesis test reliability on Travis.

Improve Hypothesis tests. - Initialize from iterables instead of lists of items in more places. - Generate arbitrarily many items (rather than max 10). - Don't include floats and text in HASHABLES. Slows example generation without actually finding more falsifying examples. - Use simpler and more concise `st.tuples(...).map(...).filter(...)` constructions rather than much more complicated `st.composite`-based strategies. - Simplify `test_iteritems_args_kw`. - Split out more namedbidict tests so each one tests one thing. - Use latest Travis pypy and pypy3. - Only use a single Hypothesis profile ("custom"). Allow any of its settings that should be tunable to be tuned via dedicated env vars (currently just "HYPOTHESIS_MAX_EXAMPLES"). - Always turn off "too_slow" health check, not just for Travis cron builds. Never want a build to fail only because tests took too long. - Set --hypothesis-verbosity="verbose" for Travis cron builds. - Set --hypothesis-show-statistics for Travis cron builds.
