diff Lib/test/test_parser.py @ 15507:34058af976ce legacy-trunk
Added tests to avoid regression on bug #125375.
roundtrip(): Show the offending syntax tree when things break; this makes
it a little easier to debug the module by adding test cases.
(Still need better tests for this module, but there's not enough time
today.)
