<p>Welcome to the release of pytest-2.1, a mature testing tool for Python,
supporting CPython 2.4-3.2, Jython and latest PyPy interpreters. See
the improved extensive docs (now also as PDF!) with tested examples here:</p>
<blockquote>
<div><a class="reference external" href="http://pytest.org/">http://pytest.org/</a></div></blockquote>
<p>The single biggest news about this release are <strong>perfected assertions</strong>
courtesy of Benjamin Peterson. You can now safely use <tt class="docutils literal"><span class="pre">assert</span></tt>
statements in test modules without having to worry about side effects
or python optimization (“-OO”) options. This is achieved by rewriting
assert statements in test modules upon import, using a PEP302 hook.
See <a class="reference external" href="http://pytest.org/assert.html#advanced-assertion-introspection">http://pytest.org/assert.html#advanced-assertion-introspection</a> for
detailed information. The work has been partly sponsored by my company,
merlinux GmbH.</p>
<p>For further details on bug fixes and smaller enhancements see below.</p>
<p>If you want to install or upgrade pytest, just type one of:</p>
<div class="highlight-python"><pre>pip install -U pytest # or
easy_install -U pytest</pre>
</div>
<p>best,

<h2>Changes between 2.0.3 and 2.1.0<a class="headerlink" href="#changes-between-2-0-3-and-2-1-0" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li>fix issue53 call nosestyle setup functions with correct ordering</li>
<li>fix issue58 and issue59: new assertion code fixes</li>
<li>merge Benjamin’s assertionrewrite branch: now assertions
for test modules on python 2.6 and above are done by rewriting
the AST and saving the pyc file before the test module is imported.
see doc/assert.txt for more info.</li>
<li>fix issue43: improve doctests with better traceback reporting on
unexpected exceptions</li>
<li>fix issue47: timing output in junitxml for test cases is now correct</li>
<li>fix issue48: typo in MarkInfo repr leading to exception</li>
<li>fix issue49: avoid confusing error when initialization partially fails</li>
<li>fix issue44: env/username expansion for junitxml file path</li>
<li>show releaselevel information in test runs for pypy</li>
<li>reworked doc pages for better navigation and PDF generation</li>
<li>report KeyboardInterrupt even if interrupted during session startup</li>
<li>fix issue 35 - provide PDF doc version and download link from index page</li>
