python doctest异常测试处理

我在名为 test2.txt 的文件中包含以下内容。

>>> def faulty():  
... yield 5  
... return 7  
Traceback(most recent call last):  
SyntaxError: 'return' with argument inside generator(<doctest test.txt[0]>,line 3)

我使用 python -m test2.txt 调用测试运行。下面的结果完全出乎我的意料。

我的想法是测试应该成功，因为我已经在 test2 中编写了预期的输出.txt 文件，它“几乎”与我从控制台输出中得到的内容匹配。我尝试添加 'File "G:\"'.... 行？但测试仍然失败。

I have the following contents in a file called test2.txt.

>>> def faulty():  
... yield 5  
... return 7  
Traceback(most recent call last):  
SyntaxError: 'return' with argument inside generator(<doctest test.txt[0]>,line 3)

I invoke the test run with python -m test2.txt. The results below are quite out of my expectation.

My thought was that the test should be successful because I have written the expected output in my test2.txt file and it 'almost' matches what I got from the console output. I tried adding the 'File "G:\"'.... line? but the test still failed.

doctest 对预期异常的格式非常谨慎。您错过了一个空格：

Traceback(most最近的调用最后): 应该是 Traceback (most最近的调用最后):

此外，这仍然会失败，因为您的回溯消息过度具体（并且也有不正确的空格）！对 doctest 使用 ELLIPSIS 或 IGNORE_EXCEPTION_DETAIL 标志，使 doctest 对匹配异常不那么挑剔，如下所示：（

>>> def faulty(): # doctest: +IGNORE_EXCEPTION_DETAIL  
...     yield 5  
...     return 7  
Traceback (most recent call last):  
SyntaxError: 'return' with argument inside generator (...)

ELLIPSIS 也可以在这里工作）

doctest is extremely careful with the format of expected exceptions. You missed a space:

Traceback(most recent call last): should be Traceback (most recent call last):

Moreover, this would still fail, as your traceback message is overly specific (and also has incorrect whitespace)! Use the ELLIPSIS or IGNORE_EXCEPTION_DETAIL flags to doctest to make doctest less picky about matching exceptions, as so:

>>> def faulty(): # doctest: +IGNORE_EXCEPTION_DETAIL  
...     yield 5  
...     return 7  
Traceback (most recent call last):  
SyntaxError: 'return' with argument inside generator (...)

(ELLIPSIS would work here too)
