# Test suite (for verifying correctness)
#
# The test suite is a list of 5- or 3-tuples.  The 5 parts of a
# complete tuple are:
# element 0: a string containing the pattern
#         1: the string to match against the pattern
#         2: the expected result (0 - SUCCEED, 1 - FAIL, 2 - SYNTAX_ERROR)
#         3: a string that will be eval()'ed to produce a test string.
#            This is an arbitrary Python expression; the available
#            variables are "found" (the whole match), and "g1", "g2", ...
#            up to "g10" contain the contents of each group, or the
#            string 'None' if the group wasn't given a value.
#         4: The expected result of evaluating the expression.
#            If the two don't match, an error is reported.
#
# If the regex isn't expected to work, the latter two elements can be omitted.
