# *****************************************************************************
# Test strategy
# -------------
# Tests are divided into two different categories:
#
# 1) The 'txt' files contain doctest style tests. These tests should cover
# basic functionality for all functions/types.
# 2) The 'py' files contain Python code that perform extensive tests, but
# may not test every function.
#
# If run by a debug build of Python, the test suite can be repeated multiple
# times to search for memory leaks.
#
# NOTE: IF THE LAST TEST IN A BLOCK OF TESTS GENERATES AN EXCEPTION, THE
# REFERENCE COUNTING IN A DEBUG BUILD GETS CONFUSED. ALWAYS ENSURE THAT
# AT LEAST ONE VALID TEST IS PERFORMED AFTER AN EXCEPTION IS RAISED!
#
# *****************************************************************************
