Release Notes

Simplistix/testfixtures (testfixtures)

v10.0.0

Compare Source

• Fixed a bug in the warning issued when a :class:Replacer is deleted with replacements still
  in place.

• Reworked :func:compare options so that typos and the like will now result
  in an exception being raised. This ended up being a breaking change if you use custom comparers
  that take options as this now has a :ref:different API <custom-comparer-options>.

• Reworked the :doc:compare documentation <comparing> to explain why you should be using it
  as well as updating the examples and explaining more fully how to configure and customise it.

v9.2.0

Compare Source

• Implement :func:like, :func:sequence, :func:contains, :func:unordered for
  strictly typed :ref:comparisons <comparison-objects>.

• Correctly type :attr:ShouldRaise.raised.

v9.1.0

Compare Source

• Add support for passing :class:StringComparison instances as parameters to
  :meth:OutputCapture.compare.

v9.0.1

Compare Source

• :attr:ShouldRaise.raised is now always an exception instance. If no exception has been raised,
  it will be a :class:~testfixtures.shouldraise.NoException instance. This prevents typing
  complaints around using an attribute that might be None.

• :func:mock_time has been reworked to return an instance of :class:~testfixtures.datetime.MockTime rather than the
  class itself. :class:~testfixtures.datetime.MockTime has also been reworked such that it can no longer be instantiated
  with the same parameters as :class:~datetime.datetime - this edge case was never supported,
  but is highlighted here in case folks were using it.

v9.0.0

Compare Source

• Python 3.11 is now the minimum supported version.

• A show_whitespace parameter has been added to :class:ShouldAssert.

• testfixtures is now fully typed, checked with mypy__ and is distributed with
  a py.typed marker file.
