I recommend you to use a set of tools developed to help programmers in the practice of BDD and TDD. This tool set is composed by: <a href="https://pypi.python.org/pypi/pycukes/0.1.2" rel="noreferrer">pycukes</a>, <a href="https://pypi.python.org/pypi/specloud/0.4.5" rel="noreferrer">specloud</a>, <a href="https://pypi.python.org/pypi/ludibrio/2.0" rel="noreferrer">ludibrio</a> and <a href="http://www.should-dsl.info/" rel="noreferrer">should-dsl</a>.

<a href="http://www.should-dsl.info/" rel="noreferrer">Should-DSL</a> will give you RSpec-like expectations. Everything you can do with RSpec expectation API, should-dsl does too. You can grab the <a href="http://github.com/rodrigomanhaes/should-dsl/tree/matchers-as-functions" rel="noreferrer">latestversion from Github</a>.

<a href="https://pypi.python.org/pypi/specloud/0.4.5" rel="noreferrer">SpecLoud</a> helps you on running BDD-like unittests. You can install it by doing

<pre><code>pip install specloud
</code></pre>

<a href="https://pypi.python.org/pypi/ludibrio/2.0" rel="noreferrer">Ludibrio</a> is a library for test doubles (Mocks, Stubs and Dummies). Install it via 

<pre><code>pip install ludibrio
</code></pre>

And <a href="https://pypi.python.org/pypi/pycukes/0.1.2" rel="noreferrer">PyCukes</a> is the main tool for BDD. It will run the Scenarios, etc. Again, 

<pre><code>pip install pycukes
</code></pre>

For more info please read the tools documentation at <a href="https://pypi.python.org/pypi" rel="noreferrer">PyPi</a>.

blocks|key|1493476|text|Pyccuracy项目致力于为Python中的BDD提供一种特定于领域的语言。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1493477|与在API级别工作的doctest不同，它对更高级别的操作进行编码，如加载网页和提交表单。我还没有用过它，但如果这就是你要找的，它看起来还是有希望的。|1493478|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

The Pyccuracy project is an effort to provide a domain-specific language for BDD in Python. 

Unlike doctest, which works at the API level, it encodes higher-level operations such as loading a web page and submitting a form. I haven't used it but it looks somewhat promising if that is what you're looking for.

I am probably completely missing the point, but what I retained of the <a href="http://dannorth.net/introducing-bdd" rel="nofollow noreferrer">original BDD paper</a> was that BDD was just <a href="http://c2.com/cgi/wiki?TestDrivenDevelopment" rel="nofollow noreferrer">TDD</a> repackaged to emphasize some best practices.

If my interpretation is correct, you can get a BDD framework just by renaming methods around in any <a href="http://www.martinfowler.com/bliki/Xunit.html" rel="nofollow noreferrer">xUnit</a> implementation. So just go ahead and use the standard library's <a href="http://www.python.org/doc/2.5.2/lib/module-unittest.html" rel="nofollow noreferrer">unittest</a>.

EDIT: A quick google turned up a <a href="http://pypi.python.org/pypi/Behaviour" rel="nofollow noreferrer">Behaviour</a> module in the <a href="http://pypi.python.org/pypi" rel="nofollow noreferrer">Cheese Shop</a>. Further <a href="http://pypi.python.org/pypi?%3Aaction=search&amp;term=BDD&amp;submit=search" rel="nofollow noreferrer">searching</a> for BDD there did not find anything else.

Which are the most advanced frameworks and tools there are available for python for practicing Behavior Driven Development? Especially finding similar tools as rspec and mocha for ruby would be great.
