- Improve the testing of the Python Cookbook

scottmlikens · scottmlikens · commit 2e9c012b8bc5 · 2013-06-25T22:36:05.000Z
- Create a recipe to test virtualenv
      - Created test_virtualenv.rb
      It will create a virtualenv directory and destroy one.
    + Test scenario will verify that bin/activate exists and the virtualenv that is to be destroyed; is.
    - Create a recipe to exert virtualenv and the pip provider
      - Created test_exert.rb
      It will install boto and psutils
    + Test scenario will verify that bin/activate exists and python can import boto and print *boto.Version*
    - Create a test scenario for the source recipe
    + Test scenario will verify that /opt/bin/python exists and returns 2.7.1

Original tests were made by Sean Porter &lt;portertech@gmail.com&gt; and exert and other test scenarios were enhanced (and created) by Scott M. Likens &lt;scott@mopub.com&gt;
