Merge tag 'ftracetest-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull ftrace test code from Steven Rostedt:
"This patch series starts a new selftests section in the
tools/testing/selftest directory called "ftrace" that holds tests
aimed at testing ftrace and subsystems that use ftrace (like kprobes).
So far only a few tests were written (by Masami Hiramatsu), but more
will be added in the near future (3.19)"
* tag 'ftracetest-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
tracing/kprobes: Add selftest scripts testing kprobe-tracer as startup test
ftracetest: Add POSIX.3 standard and XFAIL result codes
ftracetest: Add kprobe basic testcases
ftracetest: Add ftrace basic testcases
ftracetest: Initial commit for ftracetest

1 | Linux Ftrace Testcases | ||
2 | |||
3 | This is a collection of testcases for ftrace tracing feature in the Linux | ||
4 | kernel. Since ftrace exports interfaces via the debugfs, we just need | ||
5 | shell scripts for testing. Feel free to add new test cases. | ||
6 | |||
7 | Running the ftrace testcases | ||
8 | ============================ | ||
9 | |||
10 | At first, you need to be the root user to run this script. | ||
11 | To run all testcases: | ||
12 | |||
13 | $ sudo ./ftracetest | ||
14 | |||
15 | To run specific testcases: | ||
16 | |||
17 | # ./ftracetest test.d/basic3.tc | ||
18 | |||
19 | Or you can also run testcases under given directory: | ||
20 | |||
21 | # ./ftracetest test.d/kprobe/ | ||
22 | |||
23 | Contributing new testcases | ||
24 | ========================== | ||
25 | |||
26 | Copy test.d/template to your testcase (whose filename must have *.tc | ||
27 | extension) and rewrite the test description line. | ||
28 | |||
29 | * The working directory of the script is <debugfs>/tracing/. | ||
30 | |||
31 | * Take care with side effects as the tests are run with root privilege. | ||
32 | |||
33 | * The tests should not run for a long period of time (more than 1 min.) | ||
34 | These are to be unit tests. | ||
35 | |||
36 | * You can add a directory for your testcases under test.d/ if needed. | ||
37 | |||
38 | * The test cases should run on dash (busybox shell) for testing on | ||
39 | minimal cross-build environments. | ||
40 | |||
41 | * Note that the tests are run with "set -e" (errexit) option. If any | ||
42 | command fails, the test will be terminated immediately. | ||
43 | |||
44 | * The tests can return some result codes instead of pass or fail by | ||
45 | using exit_unresolved, exit_untested, exit_unsupported and exit_xfail. | ||
46 | |||
47 | Result code | ||
48 | =========== | ||
49 | |||
50 | Ftracetest supports following result codes. | ||
51 | |||
52 | * PASS: The test succeeded as expected. The test which exits with 0 is | ||
53 | counted as passed test. | ||
54 | |||
55 | * FAIL: The test failed, but was expected to succeed. The test which exits | ||
56 | with !0 is counted as failed test. | ||
57 | |||
58 | * UNRESOLVED: The test produced unclear or intermidiate results. | ||
59 | for example, the test was interrupted | ||
60 | or the test depends on a previous test, which failed. | ||
61 | or the test was set up incorrectly | ||
62 | The test which is in above situation, must call exit_unresolved. | ||
63 | |||
64 | * UNTESTED: The test was not run, currently just a placeholder. | ||
65 | In this case, the test must call exit_untested. | ||
66 | |||
67 | * UNSUPPORTED: The test failed because of lack of feature. | ||
68 | In this case, the test must call exit_unsupported. | ||
69 | |||
70 | * XFAIL: The test failed, and was expected to fail. | ||
71 | To return XFAIL, call exit_xfail from the test. | ||
72 | |||
73 | There are some sample test scripts for result code under samples/. | ||
74 | You can also run samples as below: | ||
75 | |||
76 | # ./ftracetest samples/ | ||
77 | |||
78 | TODO | ||
79 | ==== | ||
80 | |||
81 | * Fancy colored output :) | ||
