http://www.diveintopython3.net/unit-testing.html 中 9.2 A Single Question 中执行 python3 romantest1.py -v 会出现以下详细的信息
test_to_roman_known_values (__main__.KnownValues) ①
to_roman should give known result with known input ... FAIL ②
======================================================================
FAIL: to_roman should give known result with known input
----------------------------------------------------------------------
Traceback (most recent call last):
File "romantest1.py", line 73, in test_to_roman_known_values
self.assertEqual(numeral, result)
AssertionError: 'I' != None ③
----------------------------------------------------------------------
Ran 1 test in 0.016s ④
FAILED (failures=1) ⑤
但是我自己在 windows 7 系统 python3.5.2 环境下执行 python romantest1.py -v,只输出
PS E:\DiveIntoPython3> python .\romantest1.py -v
----------------------------------------------------------------------
Ran 0 tests in 0.000s
OK
代码与连接中的完全相同,不知道哪里出了问题,各位有遇到过的?或者知道是哪里的问题?
