From eeb409bde964df1956297b6775ff5f53dd98d556 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Fri, 12 Apr 2024 07:14:33 -0700 Subject: [PATCH] selftests: net: print report check location in python tests Developing Python tests is a bit annoying because when test fails we only print the fail message and no info about which exact check led to it. Print the location (the first line of this example is new): # At /root/ksft-net-drv/./net/nl_netdev.py line 38: # Check failed 0 != 10 not ok 3 nl_netdev.page_pool_check Reviewed-by: Petr Machata Link: https://lore.kernel.org/r/20240412141436.828666-4-kuba@kernel.org Signed-off-by: Jakub Kicinski --- tools/testing/selftests/net/lib/py/ksft.py | 25 ++++++++++++---------- 1 file changed, 14 insertions(+), 11 deletions(-) diff --git a/tools/testing/selftests/net/lib/py/ksft.py b/tools/testing/selftests/net/lib/py/ksft.py index c7210525981c..b4b0bfff68b0 100644 --- a/tools/testing/selftests/net/lib/py/ksft.py +++ b/tools/testing/selftests/net/lib/py/ksft.py @@ -1,6 +1,7 @@ # SPDX-License-Identifier: GPL-2.0 import builtins +import inspect from .consts import KSFT_MAIN_NAME KSFT_RESULT = None @@ -18,32 +19,34 @@ def ksft_pr(*objs, **kwargs): print("#", *objs, **kwargs) +def _fail(*args): + global KSFT_RESULT + KSFT_RESULT = False + + frame = inspect.stack()[2] + ksft_pr("At " + frame.filename + " line " + str(frame.lineno) + ":") + ksft_pr(*args) + + def ksft_eq(a, b, comment=""): global KSFT_RESULT if a != b: - KSFT_RESULT = False - ksft_pr("Check failed", a, "!=", b, comment) + _fail("Check failed", a, "!=", b, comment) def ksft_true(a, comment=""): - global KSFT_RESULT if not a: - KSFT_RESULT = False - ksft_pr("Check failed", a, "does not eval to True", comment) + _fail("Check failed", a, "does not eval to True", comment) def ksft_in(a, b, comment=""): - global KSFT_RESULT if a not in b: - KSFT_RESULT = False - ksft_pr("Check failed", a, "not in", b, comment) + _fail("Check failed", a, "not in", b, comment) def ksft_ge(a, b, comment=""): - global KSFT_RESULT if a < b: - KSFT_RESULT = False - ksft_pr("Check failed", a, "<", b, comment) + _fail("Check failed", a, "<", b, comment) def ktap_result(ok, cnt=1, case="", comment=""):
