Python类和单元测试

我通过蟒蛇新秀的工作，和我遇到的，我不得不做出一个课堂上提问时，和子类这是很好的（我相信香港专业教育学院做了右）Python类和单元测试

但我现在必须包括一些python unittest模块的测试，我不知道如何实现这一点，任何帮助将不胜感激。

class BankAccount: 
    def __init__(self): 
     self.balance = 0 

    def withdraw(self,amount): 
     if self.balance - amount <= 0: 
      print "Overdrawn, please try another option."    
     else: 
      self.balance -= amount 
      return self.balance 
    def deposit(self, amount): 
     self.balance += amount 
     return self.balance 

    def interest(self, amount): 
     percent = self.balance/100.0 * amount 
     self.balance = self.balance + percent 
     return self.balance 


class CreditAccount(BankAccount): 
    def withdraw(self,amount): 
     if self.balance - amount <= 0: 
      self.balance = self.balance - amount - 5 
      print "Overdrawn, you have been charged £5 for this." 
      return self.balance 
     else: 
      self.balance -= amount 
      return self.balance 

class StudentAccount(BankAccount): 

    def __init__(self): 
     self.balance = 500 

    def withdraw(self, amount):  
     if self.balance - amount >= -3000: 
      self.balance -= amount 
      return self.balance 
     else: 
      print "£3000 Overdraft limit reached" 
      return self.balance 


account = BankAccount() 
account1 = CreditAccount() 
account2 = StudentAccount() 
account2.deposit(500)

我想不出哪里unfortinatly这个开始，我读过章节，但我不能深入了解它 – Unknown 2012-03-27 03:01:20

也许阅读文档将有所帮助：http://docs.python.org/library/unittest.html#basic-example – Eddie 2012-03-27 03:10:13

我已阅读它，但也许我会花更多的时间在上面，尝试从那里开始和发布信息，谢谢你的帮助 – Unknown 2012-03-27 03:12:52

我只想让你开始..

my_account = BankAccount() 
balance = my_account.deposit(1000) # can also be accessed by my_account.balance

希望你可以把它从这里
