用于处理带有临时目录和文件的python测试用例的实用程序，供使用pyunit/unittest的人使用。
支持Python2.7和3.4+。

动机
单元测试应该尽可能隔离，但是在测试文件生成方法时，通常不方便 手动处理具有信息性名称且远离代码的单独输出目录。
pytest使用tmpdir夹具很容易解决这个问题，但是unittest没有这样的实用程序。
tempcase为unittest样式的测试用例提供了一个基类，其中包含用于创建临时
目录根据需要，具有自动清除功能，可出于调试目的禁用。
安装
pip install tempcase
用法
importosimporttempcaseclassMyTestCase(tempcase.TempCase):_project_name='mylibrary'deftest_creates_file(self):""" Test that ``my_file.txt`` is successfully created. The first call to ``path_to`` for a ``TestCase`` will create a directory in your default temp directory, which has the name of the project as defined above, the name of the ``TestCase``, a timestamp, and a random alphanumeric string. The first call to ``path_to`` for a test method will create a subdirectory within that, named for the test method. The test method directory and its contents will be deleted by ``tearDown``. The ``TestCase`` directory, if empty, will be cleaned up by ``tearDownClass``.
