unittest

You can download this unittest in the source files that come with the article .

您可以在本文所附带的源文件中下载这个单元测试。

One final feature to demonstrate is running a unittest within an IPython shell .

这里要展示的最后一个特性是，在IPythonShell中运行单元测试。

It is quite handy to frequently run a unittest when making changes to a module .

在对模块进行更改时，需要频繁地运行单元测试，而这也是非常容易的。

Done this way , the unittest module will accept a-v option for more verbose output .

使用这种方式时，unittest模块将接受一个-v选项以给出更详细的输出。

The unittest framework will cycle through the test functions , calling setUp , the test function , then tearDown for each test function .

unittest框架会在测试函数之间循环往复，先调用setUp、再测试函数、然后清除（tearDown）测试函数。

Also note , finally , that the Zope test frameworks only support tests that are either UnitTest instances or doctests .

最后注意，Zope测试框架只支持UnitTest实例或doctest。

It will , however , use its own regular expression to determine which of their methods are tests , rather than using the standard unittest pattern of ^ test .

但是，它会根据自己的正则表达式决定哪些方法是测试，而不使用标准的unittest模式^test。

If you write all of your tests from the ground up using only the clunky standard Python unittest module , then they will work under any testing framework you choose .

如果只使用笨拙的标准Pythonunittest模块从头编写所有测试，那么它们能够在任何测试框架中运行。

If any assertion does not evaluate to true , or if any exceptions are thrown as a part of processing , unittest will report it as a test failure or error .

如果任何assert的求值结果不是真，或是在执行过程中抛出任何异常，unittest就会报告一次测试失败或错误。

You need to add a flag to run run-e so that you can avoid getting a traceback to the unittest module in the IPython shell .

您需要添加一个标记以运行run-e，这样一来，您就可以在IPythonShell中避免回溯到单元测试模块。
