如何从档案中为单位测试装上数据?
原标题:How to load data from a file, for a unit test, in python?

我撰写了一份专门的超文本帽子,我想与几页的样本网页一下载进行单位测试。

In Java, I ve used class resources, to load data into unit tests, without having to rely on them being at a particular path on the file system. Is there a way to do this in Python?

我发现doctestfile(功能,但看来是具体测试。 我只想拿一个档案,处理一个与现有模块相对的特别超文本文件。

事先感谢任何建议!

最佳回答

a. 如果测试数据与单元测试相同,则将数据从单元测试中填入,一种解决办法:

TESTDATA_FILENAME = os.path.join(os.path.dirname(__file__),  testdata.html )


class MyTest(unittest.TestCase)

   def setUp(self):
       self.testdata = open(TESTDATA_FILENAME).read()

   def test_something(self):
       ....
问题回答

这基于Ferran的回答,但是为了避免在<代码>My Test.tearDown(上填写档案。 Resourcewarning: unlos :

TESTDATA_FILENAME = os.path.join(os.path.dirname(__file__),  testdata.html )


class MyTest(unittest.TestCase)

   def setUp(self):
       self.testfile = open(TESTDATA_FILENAME)
       self.testdata = self.testfile.read()

   def tearDown(self):
       self.testfile.close()

   def test_something(self):
       ....

您还可以使用一个“StingIO”或“StringIO”来模拟载有你档案内容的插图。

我猜测你的工作oil到:https://stackoverflow.com/questions/5137497/find- Current-directory-and-files-directory”>,以便查阅目前的档案。 然后将这一道路延伸到您的超文本档案和http://docs.python.org/library/Functions.html 。
