Actually, it checks if the dump is the same:
class ASTTestCase(unittest.TestCase):
def assertASTEqual(self, ast1, ast2):
self.assertEqual(ast.dump(ast1), ast.dump(ast2))
def check_roundtrip(self, code1, filename="internal"):
ast1 = compile(code1, filename, "exec", ast.PyCF_ONLY_AST)
unparse_buffer = io.StringIO()
unparse.Unparser(ast1, unparse_buffer)
code2 = unparse_buffer.getvalue()
ast2 = compile(code2, filename, "exec", ast.PyCF_ONLY_AST)
self.assertASTEqual(ast1, ast2)
