创建临时目录的单元测试混合。初始化时设置self.scratch_dir，完成后删除。

import unittest
from scratch_dir import ScratchDirMixin

class TestThing(CreateScratchDirectoryMixin, unittest.TestCase):
    def setUp(self):
        import json
        import os

        super(TestThing, self).setUp()

        self.local_json_file = self.get_tmp_path('example.json')
        json.dump({'a': 42}, self.local_json_file)

        print 'Example file written to scratch dir: {}'.format(self.scratch_dir)
