Howdy Michael,
I'm interested in the changes you're proposing for Python's 'unittest'
module. I am (like, I suspect, many Python coders) maintaining my own set
of extensions to the module across many projects, so I'd really like to see
many of the improvements you discuss actually in the standard library.
What assistance can I offer to help on this issue?
I intend to start working on them in August, after I have finished my
current writing commitments.
The full list of changes proposed (feel free to start - but ping me or the
list) and not shot down was something like:
Documenting that the assert method names are to be preferred over the
'FailUnless' names (this stirred up some controversy this weekend so should
probably not happen).
Adding the following new asserts:
assertIn (member, container, msg=None)
assertNotIn (member, container, msg=None)
assertIs (first, second, msg=None)
assertNotIs (first, second, msg=None)
assertRaisesWithMessage (exc_class, message, callable, *args,
**keywargs)
Several of these are implemented in other libraries (Twisted, at least).
You might save some time by grabbing them and their unit tests, rather
than re-implementing them. Twisted calls `assertIs´ `assertIdentical´,
by the way.
[snip]
Other suggestions that weren't controversial but I might not get to:
assertRaisesWithMessage taking a regex to match the error message
Actually, I remember that someone raised an object to this as being not
as flexible as some might want - an objection I agree with. Perhaps that
was overruled, but I didn't want this to slip by as "not controversial".
expect methods that collect failures and report at the end of the test
(allowing an individual test method to raise several errors without
stopping)
assertIsInstance and assertIsSubclass
The former of these is also in Twisted already, if you want to copy it.
