＆＃39;模块＆＃39;对象没有属性

Question

我是python的新手，我正在玩unittest和nosetests。

def revenue(r):
    return r * (1)

def profit (p):
    return p * (1.0-.05)

import unittest 
class MyTest(unittest.TestCase):
def test_revenue(self):
    self.assertEqual( revenue(0), 0 )
    self.assertEqual( revenue(10), 10)
    self.assertEqual( revenue(100), 100)

def test_profit(self):
    self.assertEqual( profit(0), 0)
    self.assertEqual( profit(10), 9.5)
    self.assertEqual( profit(100), 95)



unittest.main()

单元测试似乎工作正常，但是当我尝试在其上运行测试时，它总是失败并出现相同的错误＆＃34; AttributeError：＆＃39; module＆＃39;对象没有属性＆＃39; test_employee＆＃39;＆＃34;

我觉得可能有一个简单的答案，但是我很难过，任何帮助都会受到赞赏

＆＃34; test_employee＆＃34;是.py文件的名称。

我得到的跟踪错误是

＆＃34;错误：失败：属性错误（＆＃39;模块＆＃39;对象没有属性＆＃39; test_employee＆＃39;）
