Attest

---
:Release date: `in development`
:Tested on: CPython 2.5 - 2.7 and 3.1 - 3.2, PyPy 1.5

* New :doc:`attest command </running>` for discovering and running tests.
* Added the 16-color styles *light* and *dark* and the complementary
`colorscheme` option to :class:`~attest.reporters.FancyReporter`.
* New :func:`~attest.contexts.tempdir` context for creating a temporary
directory.
* New :func:`~attest.contexts.warns` context to check for warnings.
* The decorator methods now default to simply registering functions and
leaving the original in place. Added `replace_tests` and `replace_contexts`
parameters to the :class:`Tests` constructor for backwards compatibility.
* Added a bunch of new options to :meth:`Tests.run`:

* `debugger` – enter PDB when tests fail
* `fail_fast` – stop at first failure
* `full_tracebacks` – don't clean tracebacks
* `ipdb_debugger` – enter IPDB when tests fail
* `keyboard_interrupt` – let CTRL+C propagate
* `native_assert` – don't hook the assert statement
* `no_capture` – don't capture stderr and stdout
* Added :class:`~attest.reporters.XUnitReporter`.
* Added :meth:`~Tests.test_case` to complement :meth:`~Tests.test_suite`.
* The :class:`Tests` constructor can now be passed a single string without
wrapping it in iterable.
* :meth:`Tests.register` now recursively scans modules and only adds tests if
they haven't already been added.
* Support for CPython 3.2 and PyPy 1.5.

:Release date: 2011-04-19
:Tested on: CPython 2.5 - 2.7 and 3.1, PyPy 1.4.1

Bugs fixed:

* 0.5 requires progressbar 2.3; version requirement for dependency added.
* The setuptools-git plugin wasn't working well with Attest as a test
dependency with ``setup.py test``, so it has been dropped in favour of a
:file:`MANIFEST.in` file.
* Calls and attributes are now evaluated by the assert hook. The previous
behaviour was intentional, but turned out to be less helpful.
* The assert hook now injects explicit calls to :func:`globals` and
:func:`locals` rather than relying on stack frame inspection. This fixes
a bug on CPython 2.5 where :func:`inspect.stack` tried to read lines from
the source file, based on the line numbers from the generated source,
which could end fatally when the line number exceeded the number of lines
in the source file.
* Assertions are now correctly counted when tests are run more than once in
the same process.

:Release date: 2011-03-25
:Tested on: CPython 2.5 - 2.7 and 3.1, PyPy 1.4.1

Bugs fixed:

* The assert hook failed to evaluate list comprehensions and similar
constructs because the loop variable was treated as a variable to be
looked up in the symbol table.
* Variables referencing objects implementing ``__name__`` not returning a
string caused an exception to exit early, if used with the assert hook in
a failing condition.

:Code name: *Ghost Writer*
:Release date: 2011-03-08
:Tested on: CPython 2.5 - 2.7 and 3.1, PyPy 1.4.1

* Support for evaluated testing with the `assert` statement by means of an
import hook using the :mod:`_ast` module.
* Assertions of all kinds now run with ``python -O``.
* Deprecated the :class:`~attest.deprecated.Assert` class in favor of the
import hook.

* Added the :func:`~attest.contexts.raises` context manager independent
of the :class:`~attest.deprecated.Assert` class.
* Deprecated :class:`~attest.deprecated.Loader` in favor of a
:attr:`test_loader` attribute on reporters.
* Added the :class:`~attest.reporters.QuickFixReporter` for testing from
Vim and other editors.
* Test functions now get as many context arguments as their signature asks
for.
* Organized the code into modules in a package, but everything can still be
imported directly from the ``attest`` package.
* Added runnable modules for running test suites by dotted name, ``python
-mattest`` on Python 2.7 or newer, ``python -mattest.run`` on older
versions.

:Release date: 2011-01-08
:Tested on: CPython 2.5 - 2.7 and 3.1, PyPy 1.4.1

* Support for Python 3.1 and PyPy (besides existing support for 2.5-2.7).
* Reporters are now loaded via setuptools entry points, allowing
third-party packages to register themselves automatically. The
:func:`get_all_reporters` function was added to complement this
extensibility.
* :class:`TestResult` was introduced and is now passed to reporters instead
of the more limited set of arguments that were previously passed. This
change is not backwards-compatible if you have custom reporters.
* Conditional test registration: :meth:`Tests.test_if`,
:meth:`Tests.register_if`, :func:`test_if`.
* Many new :class:`Assert` methods:

* :meth:`~Assert.isinstance` and :meth:`~Assert.not_isinstance`
* :meth:`~Assert.issubclass` and :meth:`~Assert.not_issubclass`
* :meth:`~Assert.json`, :meth:`~Assert.css` and :meth:`~Assert.xpath`
* :meth:`~Assert.attr` and :meth:`~Assert.passed_to`
* Import fallbacks can be tested using :func:`disable_imports`.
* The :class:`Tests` constructor now accepts an iterable of contexts.
* Passing :class:`Assert` objects to the Assert constructor no-longer wraps
multiple levels.
* Test names now include the class name for class-based test.
* Test registration via dotted name now handles unicode.

:Release date: 2010-11-27
:Tested on: CPython 2.6

* :const:`None` if yielded from a context is no-longer passed as arguments
to tests.
* :meth:`Assert.is_` and :meth:`Assert.is_not`, if passed an
:class:`Assert` instance, will unwrap it and test against the original
object.
