python - PyDev 中的 PyUnit 错误

Question

我第一次尝试在 PyDev 中使用 PyUnit。我创建了一个 unittest.py 模块。当我执行 run as -> Python unit-test 时，出现以下错误:

Finding files... done.
Importing test modules ... done.

======================================================================
Traceback (most recent call last):

    self._testFunc.__name__)
AttributeError: 'str' object has no attribute '__name__'

My unit test is just the PyDev-generated default:

import unittest


class Test(unittest.TestCase):


    def setUp(self):
        pass


    def tearDown(self):
        pass


    def testName(self):
        pass
        print "hello test"


if __name__ == "__main__":
    #import sys;sys.argv = ['', 'Test.testName']
    unittest.main()

我希望它打印hello test。我错过了什么？

好的，在遇到类似问题几分钟后，我意识到了你的问题。您需要重命名您的文件。将它命名为 unittest.py 以外的任何名称。这会导致编译器混淆您的模块和您正在导入的单元测试模块。

其次，即使您更改了文件名，您也可能会遇到同样的错误。这是由于未从您的项目中删除 unittest.pyc 文件引起的。重命名文件，删除之前生成的 unittest.pyc 文件，测试应该可以正常运行。
