The document discusses Oktest, a new style testing library for Python introduced by Makoto Kuwata at PyCon JP 2011. It highlights the advantages of Oktest over traditional unittest in terms of readability, ease of use, and features like assertion handling and fixture injections. The document also mentions its compatibility with unittest and expresses ideas for potential future versions including Oktest for Node.js.
