Release Infrastructure/BOSS Testing/Python Test framework

Based on current searching on webs, there are two candidates for python unit test.

• unittest module in Python's standard library, named PyUnit before going into Python's standard library.
• py.test, a third-party unit test framework, need to be installed.

See below table from List of unit testing frameworks for Python

* Except py.test and Doctest, the items listed above are extensions for Python's unittest module.

• tests are run via "py.test" command line tool.
• automatic test discovery, py.test walks over the filesystem and:
  • discovers "test_*.py" test files
  • discovers "test_" functions and "Test" classes
• asserting expected exceptions
• skipping tests
• test functions and funcargs, a unique py.test feature:
  • a mechanism for managing your test fixtures
  • individual fixtures can be managed separately
  • full separation between test code and fixtures
  • can easily depend on command line options
  • convenient "builtin" funcargs provided
• adding a command line option for py.test
• particularly play with options (``py.test -h``):
  • -s disable catching of stdout/stderr
  • -x exit instantly on first failure
  • -l show locals in tracebacks.
  • --pdb start Python debugger on errors
  • --tb/fulltrace - control traceback generation.
• Customizing and Extending py.test
  • py.test hooks
