Basic setup::

    >>> import os
    >>> from __main__ import base_path, reset_env, run_pip, pyversion, lib_py, write_file, get_env

Some tests of freeze, first we have to install some stuff.  Note that
the test is a little crude at the end because Python 2.5+ adds egg
info to the standard library, so stuff like wsgiref will show up in
the freezing.  (Probably that should be accounted for in pip, but
currently it is not).  ::

    >>> reset_env()
    >>> write_file('initools-req.txt', '''\
    ... INITools==0.2
    ... # and something else to test out:
    ... simplejson<=1.7.4
    ... ''')
    >>> result = run_pip('install', '-r', 'initools-req.txt')
    >>> result = run_pip('freeze', expect_stderr=True)
    >>> print result
    Script result: ...ython... pip.main() .../test-scratch freeze
    -- stdout: --------------------
    INITools==0.2
    simplejson==1.7.4...
    <BLANKLINE>

Now lets try it with an svn checkout::

    >>> env = get_env()
    >>> result = env.run('svn', 'co', '-r3472', 'http://svn.colorstudy.com/INITools/trunk', 'initools-trunk')
    >>> result = env.run(os.path.join(env.base_path, 'bin/python'), 'setup.py', 'develop',
    ...                  cwd=os.path.join(env.base_path, 'initools-trunk'))
    >>> result = run_pip('freeze', expect_stderr=True)
    >>> print result
    Script result: ...ython... pip.main() -E .../test-scratch freeze
    -- stdout: --------------------
    -e svn+http://svn.colorstudy.com/INITools/trunk@3472#egg=INITools-0.2.1dev_r3472-py2...-dev_r3472
    simplejson==1.7.4...
    <BLANKLINE>

Now, straight from trunk (but not editable/setup.py develop)::

    >>> result = env.run(os.path.join(env.base_path, 'bin/easy_install'), 'http://svn.colorstudy.com/INITools/trunk')
    >>> result = run_pip('freeze', expect_stderr=True)
    >>> print result
    Script result: ...ython... pip.main() -E .../test-scratch freeze
    -- stderr: --------------------
    Warning: cannot find svn location for INITools==...dev-r...
    <BLANKLINE>
    -- stdout: --------------------
    ## FIXME: could not find svn URL in dependency_links for this package:
    INITools==...dev-r...
    simplejson==1.7.4...
    <BLANKLINE>

Bah, that's no good!  Let's give it a hint::

    >>> result = run_pip('freeze', '-f', 'http://svn.colorstudy.com/INITools/trunk#egg=INITools-dev', expect_stderr=True)
    >>> print result
    Script result: ...ython... pip.main() -E .../test-scratch freeze -f http://svn.colorstudy.com/INITools/trunk#egg=INITools-dev
    -- stdout: --------------------
    -f http://svn.colorstudy.com/INITools/trunk#egg=INITools-dev
    # Installing as editable to satisfy requirement INITools==...dev-r...:
    -e svn+http://svn.colorstudy.com/INITools/trunk@...#egg=INITools-...dev_r...
    simplejson==1.7.4...
    <BLANKLINE>

What about a Git clone?::

    >>> reset_env()
    >>> env = get_env()
    >>> result = env.run('git', 'clone', 'git://github.com/jezdez/django-pagination.git', 'django-pagination')
    >>> result = env.run('git', 'checkout', '1df6507872d73ee387eb375428eafbfc253dfcd8',
    ...                  cwd=os.path.join(env.base_path, 'django-pagination'), expect_stderr=True)
    >>> result = env.run(os.path.join(env.base_path, 'bin/python'), 'setup.py', 'develop',
    ...                  cwd=os.path.join(env.base_path, 'django-pagination'))
    >>> result = run_pip('freeze', expect_stderr=True)
    >>> print result
    Script result: ...ython... pip.main() -E .../test-scratch freeze
    -- stdout: --------------------
    -e git://github.com/jezdez/django-pagination.git@...#egg=django_pagination-...
    ...

    >>> result = run_pip('freeze', '-f', 'git://github.com/jezdez/django-pagination.git#egg=django_pagination', expect_stderr=True)
    >>> print result
    Script result: ...ython... pip.main() -E .../test-scratch freeze -f git://github.com/jezdez/django-pagination.git#egg=django_pagination
    -- stdout: --------------------
    -f git://github.com/jezdez/django-pagination.git#egg=django_pagination
    -e git://github.com/jezdez/django-pagination.git@...#egg=django_pagination-...-dev
    ...

Now what about Mercurial::

    >>> reset_env()
    >>> env = get_env()
    >>> result = env.run('hg', 'clone', '-r', 'f8f7eaf275c5', 'http://bitbucket.org/jezdez/django-dbtemplates/', 'django-dbtemplates')
    >>> result = env.run(os.path.join(env.base_path, 'bin/python'), 'setup.py', 'develop',
    ...                  cwd=os.path.join(env.base_path, 'django-dbtemplates'))
    >>> result = run_pip('freeze', expect_stderr=True)
    >>> print result
    Script result: ...ython... pip.main() -E .../test-scratch freeze
    -- stdout: --------------------
    -e hg+http://bitbucket.org/jezdez/django-dbtemplates/@...#egg=django_dbtemplates-...
    ...

    >>> result = run_pip('freeze', '-f', 'hg+http://bitbucket.org/jezdez/django-dbtemplates#egg=django_dbtemplates', expect_stderr=True)
    >>> print result
    Script result: ...ython... pip.main() -E .../test-scratch freeze -f hg+http://bitbucket.org/jezdez/django-dbtemplates#egg=django_dbtemplates
    -- stdout: --------------------
    -f hg+http://bitbucket.org/jezdez/django-dbtemplates#egg=django_dbtemplates
    -e hg+http://bitbucket.org/jezdez/django-dbtemplates/@...#egg=django_dbtemplates-...
    ...

Heck, now look in the Bazaar::

    >>> reset_env()
    >>> env = get_env()
    >>> result = env.run('bzr', 'checkout', '-r', '174', 'http://bazaar.launchpad.net/%7Edjango-wikiapp/django-wikiapp/release-0.1/', 'django-wikiapp')
    >>> result = env.run(os.path.join(env.base_path, 'bin/python'), 'setup.py', 'develop',
    ...                  cwd=os.path.join(env.base_path, 'django-wikiapp'))
    >>> result = run_pip('freeze', expect_stderr=True)
    >>> print result
    Script result: ...ython... pip.main() -E .../test-scratch freeze
    -- stdout: --------------------
    -e bzr+http://bazaar.launchpad.net/...django-wikiapp/django-wikiapp/release-0.1/@...#egg=django_wikiapp-...
    ...

    >>> result = run_pip('freeze', '-f', 'bzr+http://bazaar.launchpad.net/%7Edjango-wikiapp/django-wikiapp/release-0.1/#egg=django-wikiapp', expect_stderr=True)
    >>> print result
    Script result: ...ython... pip.main() -E .../test-scratch freeze -f bzr+http://bazaar.launchpad.net/%7Edjango-wikiapp/django-wikiapp/release-0.1/#egg=django-wikiapp
    -- stdout: --------------------
    -f bzr+http://bazaar.launchpad.net/...django-wikiapp/django-wikiapp/release-0.1/#egg=django-wikiapp
    -e bzr+http://bazaar.launchpad.net/...django-wikiapp/django-wikiapp/release-0.1/@...#egg=django_wikiapp-...
    ...


Test that wsgiref (from global site-packages) is reported normally, but not with --local::

    >>> reset_env()
    >>> result = run_pip('install', 'initools==0.2')
    >>> result = run_pip('freeze', expect_stderr=True)
    >>> print result
    Script result: ...ython... pip.main() .../test-scratch freeze
    -- stdout: --------------------
    INITools==0.2
    wsgiref==...
    <BLANKLINE>
    >>> result2 = run_pip('freeze', '--local', expect_stderr=True)
    >>> print result2
    Script result: ...ython... pip.main() .../test-scratch freeze --local
    -- stdout: --------------------
    INITools==0.2
    <BLANKLINE>
