Python Testing Fundamentals
summary
Covers concrete examples: assert statements as reality checks (shows BigBiz bottom_line/growth returning -1,000,000, triggering AssertionError) and that assertions disable with the -O switch; demonstrates unittest: subclassing TestCase, setUp/tearDown, TestSuite selection and discovery, running tests via setup.py; shows doctest examples (Fibonacci and triangular functions, tests for <100 and <10), and converting doctests into unit tests with doctest.DocTestSuite; all demo tests run and pass (4 tests, 0 failures) on Python 3.2.3.
