Add support for loading tests from eggs

[jpellerin]

Support for loading tests from eggs should be added, so that eg.:

nosetests some-distribution.egg

will work. This should done via a plugin.

A workaround is to install a project using

easy_install --always-unzip

Or from source using

python setup.py easy_install --always-unzip

See #150 for details on the current (broken) behavior with zipped eggs. nose fails to
load from zipped eggs, even when given the package name, not a .egg file.

This should be quite easy, in loadTestsFromNames you can use pkg_resources to return
a list of filenames from the zip. Essentially, pkg_resources will have unzipped the
whole thing, but thats the only way I can see other plugins getting a chance to
process things.

However, pkg_resources seems a bit braindead when getting the contents of packages
(see below). You can use pkg_resources.ZipProvider._index, but that looks a bit
private to me.

Has anyone had any luck with discovering what is in the package from the
pkg_resources public API?

In [96]: pkg_resources.resource_listdir('simplejson', 'tests')
Out[96]:
['test_indent.pyc',
...
'test_unicode.pyc']

In [97]: pkg_resources.resource_listdir('simplejson', '')
Out[97]: []

In [98]: pkg_resources.resource_listdir('simplejson', '')
Out[98]: []

In [99]: pkg_resources.resource_listdir('simplejson', '/')
Out[99]: []

Nose 0.10.3 fails to find tests even in unzipped eggs for me (testing PyMC). I notice this issue has not been
updated in some time. Has someone found a solution/workaround?

This issue seems to have been around for at least a year and is still unresolved as far as I can tell...

When you install an egg, setuptools explicitly changes the permissions of all *.py files to a+x (755), making
them executable. By default, nose refuses to search for tests in executable scripts, out of security concerns.
Nose therefore skips all the tests in the egg.

This behaviour can be overridden with a command-line option to nosetests (--exe), which solves the problem
for me. It still means that built-in tests of packages like numpy 1.3.0 do not work out of the box.

For more history on the issue, see http://mail.python.org/pipermail/distutils-sig/2008-April/009396.html
