- # Regex test suite and benchmark suite v1.5a2
- # Due to the use of r"aw" strings, this file will
- # only work with Python 1.5 or higher.
-
- # The 3 possible outcomes for each pattern
- [SUCCEED, FAIL, SYNTAX_ERROR] = range(3)
-
- # Benchmark suite (needs expansion)
- #
- # The benchmark suite does not test correctness, just speed. The
- # first element of each tuple is the regex pattern; the second is a
- # string to match it against. The benchmarking code will embed the
- # second string inside several sizes of padding, to test how regex
- # matching performs on large strings.
-
- benchmarks = [
- ('Python', 'Python'), # Simple text literal
- ('.*Python', 'Python'), # Bad text literal
- ('.*Python.*', 'Python'), # Worse text literal
- ('.*\\(Python\\)', 'Python'), # Bad text literal with grouping
-
- ('(Python\\|Perl\\|Tcl', 'Perl'), # Alternation
- ('\\(Python\\|Perl\\|Tcl\\)', 'Perl'), # Grouped alternation
- ('\\(Python\\)\\1', 'PythonPython'), # Backreference
- # ('\\([0a-z][a-z]*,\\)+', 'a5,b7,c9,'), # Disable the fastmap optimization
- ('\\([a-z][a-z0-9]*,\\)+', 'a5,b7,c9,') # A few sets
- ]
-
- # 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 (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 "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.
