我的自定义异常类:
class MyCustomException(Exception):
pass
class MyCustomRestException(MyCustomException):
def __init__(self, status, uri, msg=""):
self.uri = uri
self.status = status
self.msg = msg
super(MyCustomException, self).__init__(msg)
def __str__(self):
return "HTTP ERROR %s: %s \n %s" % (self.status, self.msg, self.uri)
我的测试
# note: @raises(MyCustomRestException) works by itself
@raises(MyCustomRestException, 'HTTP ERROR 403: Invalid User')
def test_bad_token():
sc = SomeClass('xxx', account_number)
result = ec.method_that_generates_exception()
这是鼻子吐出来的东西

所以 ...
我的问题有两个:
- 如何修复此错误?
- 我如何测试(单独或全部):
- 异常类型
- 异常状态
- 异常.uri
- 异常.msg
解决方案:在 alynna 的帮助下(下)
这很好用。
