python - 为什么 nosy (nose2) 出错但 python 运行测试正常

问题描述

当我保存文件时，我试图让测试持续运行。
我试着用爱管闲事。

我可以运行我的测试python test_1.py

$ python test_1.py
..
----------------------------------------------------------------------
Ran 2 tests in 0.000s

OK

但是nose2给出了

$ nose2

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK
E
======================================================================
ERROR: test_1 (nose2.loader.ModuleImportFailure)
----------------------------------------------------------------------
ImportError: Failed to import test module: test_1

Ran 1 test in 0.000s

FAILED (errors=1)

$ cat test_1.py 
import unittest
from mycode import *
class MyFirstTests(unittest.TestCase):
  def test_hello(self):
    self.assertEqual(hello_world(), 'hello world')
  def test_goodbye(self):
    self.assertEqual(goodbye_world(), 'goodbye world')
unittest.main()

$ cat mycode.py
def hello_world():
  return 'hello world'
def goodbye_world():
  return 'goodbye world'

解决方案

我不确定，但是unittest.main()在测试内部调用会导致鼻子2出现问题吗？约定是：

if __name__ == "__main__":
  unittest.main()

这样另一个跑步者（例如nose2）在运行时不会调用unittest。
