发现命令在python unittest中不起作用

[英]discover command not working in python unittest

I am new to Python. 我是Python的新手。 I am trying to understand discover option python unittest module. 我试图了解发现选项python unittest模块。 I have written two test scripts, which contains same tests(the same file is replicated, to test discover option), whose contents are given below : . 我编写了两个测试脚本,其中包含相同的测试(复制了相同的文件以测试Discover选项),其内容如下:

testFirst.py testFirst.py

import unittest

class Test(unittest.TestCase):

    def testFailure(self):

        self.assertFalse(True)

    def testError(self):
        0 / 0

    def testPass(self):
        self.assertTrue(True)

import sys
sys.argv.append("-v")
unittest.main()

testSecond.py testSecond.py

import unittest

class Test(unittest.TestCase):

    def testFailure(self):

        self.assertFalse(True)

    def testError(self):
        0 / 0

    def testPass(self):
        self.assertTrue(True)

import sys
sys.argv.append("-v")
unittest.main()

Output 输出量

Now when I run "python -m unittest discover" command from command prompt, I get the following output : 现在,当我从命令提示符运行“ python -m unittest discover”命令时,得到以下输出:

testError (testFirst.Test) ... ERROR

Which gives the impression that the tests get executed more than one time. 给人的印象是测试执行了多次。 Why is this happening? 为什么会这样呢? What do I do wrong? 我做错了什么?

If you remove the last 3 lines in each file and instead pass the verbose option -v when calling unittest , it runs the tests exactly once: 如果您删除每个文件的最后3行,而是在调用unittest时通过详细选项 -v ,则它将只运行一次测试:

python -m unittest discover -v

Result: 结果:

testError (test_first.Test) ... ERROR
testFailure (test_first.Test) ... FAIL
testPass (test_first.Test) ... ok
testError (test_second.Test) ... ERROR
testFailure (test_second.Test) ... FAIL
