 Provide unit testing for our project's Python code.

 Background
 ==========
 
-As the mantra says, "Untested code is broken code." The Python
-community has had a long culture of writing test scripts which ensure
-that your code works correctly as you write it and maintain it in the
-future. Pyramid has always had a deep commitment to testing,
-with 100% test coverage from the earliest pre-releases.
-
-Python includes a
-:ref:`unit testing framework <python:unittest-minimal-example>` in its
-standard library. Over the years a number of Python projects, such as
-`nose <https://pypi.python.org/pypi/nose/>`_, have extended this
-framework with alternative test runners that provide more convenience
-and functionality. The Pyramid developers use ``nose``, which we'll thus
-use in this tutorial.
-
-Don't worry, this tutorial won't be pedantic about "test-driven
-development" (TDD). We'll do just enough to ensure that, in each step,
-we haven't majorly broken the code. As you're writing your code you
-might find this more convenient than changing to your browser
-constantly and clicking reload.
-
-We'll also leave discussion of
-`coverage <https://pypi.python.org/pypi/coverage>`_ for another section.

 Analysis
 ========
 
-Our ``tests.py`` imports the Python standard unit testing framework. To
-make writing Pyramid-oriented tests more convenient, Pyramid supplies
-some ``pyramid.testing`` helpers which we use in the test setup and
-teardown. Our one test imports the view, makes a dummy request, and sees
-if the view returns what we expected.

-The ``tests.TutorialViewTests.test_hello_world`` test is a small
-example of a unit test. First, we import the view inside each test. Why
-not import at the top, like in normal Python code? Because imports can
-cause effects that break a test. We'd like our tests to be in *units*,
-hence the name *unit* testing. Each test should isolate itself to the
-correct degree.

 Note that our use of ``pyramid.testing.setUp()`` and
 ``pyramid.testing.tearDown()`` aren't actually necessary here; they are only
 necessary when your test needs to make use of the ``config`` object (it's a
 Configurator) to add stuff to the configuration state before calling the view.

 Extra Credit
 ============
 
-#. Change the test to assert that the response status code should be
-   ``404`` (meaning, not found.) Run ``nosetests`` again. Read the
-   error report and see if you can decipher what it is telling you.

 #. How could we add a unit test assertion to test the HTML value of the
    response body?
