From 0e2793c413d94cc9ea5ad71804817c241719bf82 Mon Sep 17 00:00:00 2001 From: Terry Jan Reedy Date: Tue, 21 Jan 2014 03:07:43 -0500 Subject: [PATCH] Issue #16655: Explain why Idle's test_calltips has 'fragile' tests of builtins. I do not expect a problem in 2.7, but backported this anyway, 'in case'. --- Lib/idlelib/idle_test/test_calltips.py | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/Lib/idlelib/idle_test/test_calltips.py b/Lib/idlelib/idle_test/test_calltips.py index 4fbb565eb0..0560a51223 100644 --- a/Lib/idlelib/idle_test/test_calltips.py +++ b/Lib/idlelib/idle_test/test_calltips.py @@ -34,6 +34,13 @@ tc = TC() signature = ct.get_arg_text # 2.7 and 3.x use different functions class Get_signatureTest(unittest.TestCase): + # The signature function must return a string, even if blank. + # Test a variety of objects to be sure that none cause it to raise + # (quite aside from getting as correct an answer as possible). + # The tests of builtins may break if the docstrings change, + # but a red buildbot is better than a user crash (as has happened). + # For a simple mismatch, change the expected output to the actual. + def test_builtins(self): # 2.7 puts '()\n' where 3.x does not, other minor differences -- 2.50.1
