doctest
是否支持输出和异常混合在一起?
一个例子是:
>>> def foo():
... print 'hello world!'
>>> foo()
hello world!
>>> def bar():
... raise Exception()
>>> bar()
Traceback (most recent call last):
...
Exception
>>> def foo_bar():
... foo()
... bar()
>>> foo_bar()
hello world!
Traceback (most recent call last):
...
Exception
我希望所有三个案例都应该成功,但只有两个成功,请参阅
$ python -m doctest -v /tmp/1.py
Trying:
def foo():
print 'hello world!'
Expecting nothing
ok
Trying:
foo()
Expecting:
hello world!
ok
Trying:
def bar():
raise Exception()
Expecting nothing
ok
Trying:
bar()
Expecting:
Traceback (most recent call last):
...
Exception
ok
Trying:
def foo_bar():
foo()
bar()
Expecting nothing
ok
Trying:
foo_bar()
Expecting:
hello world!
Traceback (most recent call last):
...
Exception

最佳答案
docs说你不能那样做:
Examples containing both expected output and an exception are not supported. Trying to guess where one ends and the other begins is too error-prone, and that also makes for a confusing test.
