Depending on how well the previous test works in the CI we might want to disable disruptive tests by default and only let the developers run them manually. KSFT framework runs disruptive tests by default. DISRUPTIVE=False environment (or config file) can be used to disable these tests. ksft_setup should be called by the test cases that want to use new decorator (ksft_setup is only called via NetDrvEnv/NetDrvEpEnv for now). In the future we can add similar decorators to, for example, avoid running slow tests all the time. And/or have some option to run only 'fast' tests for some sort of smoke test scenario. $ DISRUPTIVE=False ./stats.py KTAP version 1 1..5 ok 1 stats.check_pause ok 2 stats.check_fec ok 3 stats.pkt_byte_sum ok 4 stats.qstat_by_ifindex ok 5 stats.check_down # SKIP marked as disruptive # Totals: pass:4 fail:0 xfail:0 xpass:0 skip:1 error:0 v2: - convert from cli argument to env variable (Jakub) Signed-off-by: Stanislav Fomichev --- Cc: Shuah Khan Cc: Joe Damato Cc: Petr Machata Cc: linux-kselftest@vger.kernel.org --- .../selftests/drivers/net/lib/py/env.py | 5 +-- tools/testing/selftests/drivers/net/stats.py | 2 ++ tools/testing/selftests/net/lib/py/ksft.py | 32 +++++++++++++++++++ 3 files changed, 37 insertions(+), 2 deletions(-) diff --git a/tools/testing/selftests/drivers/net/lib/py/env.py b/tools/testing/selftests/drivers/net/lib/py/env.py index a5e800b8f103..1ea9bb695e94 100644 --- a/tools/testing/selftests/drivers/net/lib/py/env.py +++ b/tools/testing/selftests/drivers/net/lib/py/env.py @@ -4,6 +4,7 @@ import os import time from pathlib import Path from lib.py import KsftSkipEx, KsftXfailEx +from lib.py import ksft_setup from lib.py import cmd, ethtool, ip from lib.py import NetNS, NetdevSimDev from .remote import Remote @@ -14,7 +15,7 @@ from .remote import Remote src_dir = Path(src_path).parent.resolve() if not (src_dir / "net.config").exists(): - return env + return ksft_setup(env) with open((src_dir / "net.config").as_posix(), 'r') as fp: for line in fp.readlines(): @@ -30,7 +31,7 @@ from .remote import Remote if len(pair) != 2: raise Exception("Can't parse configuration line:", full_file) env[pair[0]] = pair[1] - return env + return ksft_setup(env) class NetDrvEnv: diff --git a/tools/testing/selftests/drivers/net/stats.py b/tools/testing/selftests/drivers/net/stats.py index 93f9204f51c4..4c58080cf893 100755 --- a/tools/testing/selftests/drivers/net/stats.py +++ b/tools/testing/selftests/drivers/net/stats.py @@ -3,6 +3,7 @@ from lib.py import ksft_run, ksft_exit, ksft_pr from lib.py import ksft_ge, ksft_eq, ksft_in, ksft_true, ksft_raises, KsftSkipEx, KsftXfailEx +from lib.py import ksft_disruptive from lib.py import EthtoolFamily, NetdevFamily, RtnlFamily, NlError from lib.py import NetDrvEnv from lib.py import ip, defer @@ -134,6 +135,7 @@ rtnl = RtnlFamily() ksft_eq(cm.exception.nl_msg.extack['bad-attr'], '.ifindex') +@ksft_disruptive def check_down(cfg) -> None: try: qstat = netfam.qstats_get({"ifindex": cfg.ifindex}, dump=True) diff --git a/tools/testing/selftests/net/lib/py/ksft.py b/tools/testing/selftests/net/lib/py/ksft.py index f26c20df9db4..a9a24ea77226 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 functools import inspect import sys import time @@ -10,6 +11,7 @@ from .utils import global_defer_queue KSFT_RESULT = None KSFT_RESULT_ALL = True +KSFT_DISRUPTIVE = True class KsftFailEx(Exception): @@ -127,6 +129,36 @@ KSFT_RESULT_ALL = True KSFT_RESULT = False +def ksft_disruptive(func): + """ + Decorator that marks the test as disruptive (e.g. the test + that can down the interface).
