Python doctest: Skip entire block?

Question

I've got a Python module with docstrings in class methods, and a real-world example in the module docstring. The distinction is that the method-docstrings have been carefully crafted to be utterly repeatable tests, while the real-world example is just a copy'n'paste of the history from a Linux shell - which happened to invoke the python interpreter.

E.g.

"""
Real-world example:

# python2.5
Python 2.5 (release25-maint, Jul 20 2008, 20:47:25)
[GCC 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from packagename import module
>>> module.show_real_world_usage()
'Hello world!'
"""

class SomeClass(object):
    def someMethod(self):
        """
        >>> 1 == 1
        True
        """

I want to run the doctest in SomeClass.someMethod, but not in the module's docstrings.

Doctest's +SKIP directive only works per line, which would mean adding 10s of lines to my real-world example. Ugly!

Is there a way to make doctest skip an entire block? A bit like <!-- ... --> in HTML?

Answer 1

If it's not an actual doctest by any means, you can just assign the value to a variable. For example,

example_usage = """
Real-world example:

# python2.5
...
"""

will cause that "test" to not be evaluated.

It might be better to use __example_usage__ (or something else surrounded by double-underscores) so that it's clear that's a "magic" variable and not a variable to be used within the context of the script.

Answer 2

My solution has been to trim the the 3-character >>> and ... leaders where I want doctest to skip over them, making them 2-characters.

So

"""
>>> from packagename import module
>>> module.show_real_world_usage()
'Hello world!'
"""

has become

"""
>> from packagename import module
>> module.show_real_world_usage()
'Hello world!'
"""

Epydoc doesn't display this as nicely as it does doctests, but I can live with this. A skip-until-further-notice directive in doctest would be welcome though.
