From 915de2adb584acea89f3f654a6c9b329f682100f Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Mon, 29 Sep 2014 12:02:11 +0000 Subject: [PATCH] ftracetest: Add POSIX.3 standard and XFAIL result codes Add XFAIL and POSIX 1003.3 standard codes (UNRESOLVED/ UNTESTED/UNSUPPORTED) as result codes. These are used for the results that test case is expected to fail or unsupported feature (by config). To return these result code, this introduces exit_unresolved, exit_untested, exit_unsupported and exit_xfail functions, which use real-time signals to notify the result code to ftracetest. This also set "errexit" option for the testcases, so that the tests don't need to exit explicitly. Note that if the test returns UNRESOLVED/UNSUPPORTED/FAIL, its test log including executed commands is shown on console and main logfile as below. ------ # ./ftracetest samples/ === Ftrace unit tests === [1] failure-case example [FAIL] execute: /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/fail.tc + . /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/fail.tc ++ cat non-exist-file cat: non-exist-file: No such file or directory [2] pass-case example [PASS] [3] unresolved-case example [UNRESOLVED] execute: /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/unresolved.tc + . /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/unresolved.tc ++ trap exit_unresolved INT ++ kill -INT 29324 +++ exit_unresolved +++ kill -s 38 29265 +++ exit 0 [4] unsupported-case example [UNSUPPORTED] execute: /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/unsupported.tc + . /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/unsupported.tc ++ exit_unsupported ++ kill -s 40 29265 ++ exit 0 [5] untested-case example [UNTESTED] [6] xfail-case example [XFAIL] # of passed: 1 # of failed: 1 # of unresolved: 1 # of untested: 1 # of unsupported: 1 # of xfailed: 1 # of undefined(test bug): 0 ------ Link: http://lkml.kernel.org/p/20140929120211.30203.99510.stgit@kbuild-f20.novalocal Acked-by: Namhyung Kim Signed-off-by: Masami Hiramatsu Signed-off-by: Steven Rostedt --- tools/testing/selftests/ftrace/README | 37 ++++++ tools/testing/selftests/ftrace/ftracetest | 124 +++++++++++++++--- .../testing/selftests/ftrace/samples/fail.tc | 4 + .../testing/selftests/ftrace/samples/pass.tc | 3 + .../selftests/ftrace/samples/unresolved.tc | 4 + .../selftests/ftrace/samples/unsupported.tc | 3 + .../selftests/ftrace/samples/untested.tc | 3 + .../testing/selftests/ftrace/samples/xfail.tc | 3 + .../selftests/ftrace/test.d/00basic/basic2.tc | 3 +- .../selftests/ftrace/test.d/00basic/basic3.tc | 6 +- .../ftrace/test.d/kprobe/add_and_remove.tc | 12 +- .../ftrace/test.d/kprobe/busy_check.tc | 15 +-- .../testing/selftests/ftrace/test.d/template | 5 + 13 files changed, 189 insertions(+), 33 deletions(-) create mode 100644 tools/testing/selftests/ftrace/samples/fail.tc create mode 100644 tools/testing/selftests/ftrace/samples/pass.tc create mode 100644 tools/testing/selftests/ftrace/samples/unresolved.tc create mode 100644 tools/testing/selftests/ftrace/samples/unsupported.tc create mode 100644 tools/testing/selftests/ftrace/samples/untested.tc create mode 100644 tools/testing/selftests/ftrace/samples/xfail.tc diff --git a/tools/testing/selftests/ftrace/README b/tools/testing/selftests/ftrace/README index b8631f03e754..182e76fa4b82 100644 --- a/tools/testing/selftests/ftrace/README +++ b/tools/testing/selftests/ftrace/README @@ -38,6 +38,43 @@ extension) and rewrite the test description line. * The test cases should run on dash (busybox shell) for testing on minimal cross-build environments. + * Note that the tests are run with "set -e" (errexit) option.
