# 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 (SUCCEED, FAIL, 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 "g99" contain the contents of each group, or the
|
||||||
|
# string 'None' if the group wasn't given a value, or the
|
||||||
|
# string 'Error' if the group index was out of range;
|
||||||
|
# also "groups", the return value of m.group() (a tuple).
|
||||||
|
# 4: The expected result of evaluating the expression.
|
||||||
|
# If the two don't match, an error is reported.
