I agree with Ben here. Despite the popularity of nose (I think it is nose?) which uses `assert` for testing, I think that is a gross misuse of the statement. It is okay to use assertions this way for quick and dirty ad hoc testing, say at the command line, but IMO totally inappropriate for anything more formal, like unit testing. If for no other reason than the use of `assert` for testing makes it impossible to test your code when running with the Python -O (optimize) switch. For more detail on the uses, and abuses, of `assert` see this: Of course you do NOT use assert in unit tests but I provided just test code to show my problem. Of course I take nose and hamcrest and code coverage ...

Mock object but also assert method calls?
Hi,
How about asserting that test2 of class Bar is called?
Of course I can do a patch for a concrete method but
I was looking for something like:
mocked_object.assert_method_called_with(name=test2, hello)
If find following totally different to the normal API which
is provided by the mock library:
assert call().test2(hello) in mocked_objects.mock_calls
Is there a better way?
APPENDIX:
Foo delegates calls to Bar.
[code]
from mock import patch
with patch(__main__.Bar) as mocked_object:
foo = Foo()
foo.test1()
foo.test2(hello)
print(mocked_object.mock_calls)
# print all calls (c'tor as well as normal methods)
for name, args, kwargs in mocked_object.mock_calls:
print(name, args, kwargs)
[/code]
Generates:
class '__main__.Bar'
test1: Foo has been called
test2: Foo has been called with value hello
[call(), call().test1(), call().test2('hello')]
('', (), {})
('().test1', (), {})
('().test2', ('hello',), {})

xmlrpc: problems with socket handling, close, shutdown of server, TIME_WAIT, ...
Hi, taking the xml-rpc derived from standard example is working - basically - but with following scenario I do not understand the problem. Maybe you can help: - one Unittest that does create the xmlrpc server in a thread in setUp and shutdown of it in tearDown. The xml-rcp server does store/load a value for a key. (It's for testing/learning purpose) Problem(s): - If I run the test method twice (copy and paste and rename) then I get a error: [Errno 98] Address already in use (I assumend the tearDown would have closed all sockets) - Because of this I removed that second method and so it's fine but checking with netstat -n | grep port I see as many sockets in TIME_WAIT as I did xml-rpc calls. Also that python test is not running anymore it take some time until those entries vanish from the netstat list. Question(s): I assumed that calling the shutdown of the server (in tearDown) does close all sockets. The SimpleXMLRPCServer is derived from SocketServer.TCPServer and those one is derived from BaseServer. Those has the shutdown which is documented to stop the serve_forever loop. Is this correct or do I have to shutdown in another way? At client side I'm using the ServerProxy. It does obviously not have a close. From code it looks like that I could do something like proxy(close)() but that looks somehow wired? Can I close a proxy?, should I?, ... what is the way? -- https://mail.python.org/mailman/listinfo/python-list
Re: Why Python 3?
Hi, I can't give you the advise for a concrete version anyway there are lot of arguments given by the other posters. BUT there is a way how you can circumvent the problem to some extend: Are you intending to use Jenkins? I don't want to convince you here why to use Jenkins but maybe I don't need to and THEN you just install the ShiningPanda plugin and each time your project is build automatically because of a change all tests are running across multiple Python versions. This way you won't have too many problems to switch to another newer Python version. Keep the build green. What is the general feel of /this/ community? I'm about to start a large scale Python project. Should it be done in 2 or 3? What are the benefits, aside from the 'it's the future' argument? -- https://mail.python.org/mailman/listinfo/python-list

Decode II (more complex)
Hi all,
I have written a small python xmlrpc server which checks logfiles of a
build
sending notifications to the responsible teams. On a machine I'm
forced to
a problem with one logfile with special characters inside generated by
a
gnu compiler.
Using cheetah for generating the HTML mail I get a:
('ascii' codec can't decode byte 0xe2 in position 25868: ordinal not
in range(128))
I have found characters like this:
error: expected type-specifier before â8098Assocâ8099
(copy and paste of a linux console)
I have tried different mechanism but very probably I do not understand
how the decode/encode functionality is working. Can somebody help me
to get out of that problem?
Thanks in advance

Re: Decode II (more complex)
Your email(s) get send as 7 bit (ASCII). Email them as utf-8 and I guess

Re: Problem with an huge dictionary
The question is: Is there a limit on the number of entries a dictionary can have i jython? I wrote a little app where my data is stored in a huge dictionary (11746 entries) generated with a python script. When I try to import the dictionary, jython complains with the following message: 1) You did not say what you have saved (content of your dictionary). 2) You did not say how you have saved. From the callstack - also I have never used jython - it looks like that there is a try to create a class. It looks like - I may be wrong - that you have saved user objects in your dictionary - have you? If so you might fail on loading those objects - especially when your program does not have the code for it. More details are required... -- http://mail.python.org/mailman/listinfo/python-list

Some are saying that using Java and Swing are the best way to write applications. But nothing is for free except the most languages you can download and install. When you have no idea about software development you should have a look there first. Do you want some little scripting only to get some jobs easier done - well - you're right to use python.
