* perf tools: Add test for parsing with no sample_id_all bitAdrian Hunter2013-09-05
| | | | | | | | | | | | | | | | | | | | Add a test for parsing a non-sample event when there is more than one selected event but no sample_id_all bit set. The test fails because of a bug in the evlist logic. That is fixed in a separate patch.

* perf tests: Add 'keep tracking' testAdrian Hunter2013-09-02
| | | | | | | | | | | | | | | | | | | | | Add a test for the newly added PERF_COUNT_SW_DUMMY event.

* perf tests: Test breakpoint overflow signal handlerJiri Olsa2013-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding automated test for breakpoint event signal handler checking if it's executed properly. The test is related to the proper handling of the RF EFLAGS bit on x86_64, but it's generic for all archs. First we check the signal handler is properly called and that the following debug exception return to user space wouldn't trigger recursive breakpoint. This is related to x86_64 RF EFLAGS bit being managed in a wrong way. Second we check that we can set breakpoint in signal handler, which is not possible on x86_64 if the signal handler is executed with RF EFLAG set. This test is inpired by overflow tests done by Vince Weaver. Signed-off-by: Jiri Olsa <jolsa@redhat.com> Cc: "H.

* perf tests: Add return states enum for testsJiri Olsa2013-01-24
| | | | | | | | | | | | | | | | | | | | Test can currently return one of 3 states: ok, fail, skip. The ok and fail states are self-explanatory. The skip state means that some of the conditions for running the test was not met, making it impossible to even run the test. For instance, if the hardware doesn't support the 'precise' level required by a test, it will be skipped.

* perf test: Add a test case for hists__{match,link}Namhyung Kim2013-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | As they are used from diff and event group report, add a test case to verify their behaviors. In this test I made a fake machine and two evsel. Each evsel got 10 samples (so hist entries) - 5 are common and the rests are not. So after hists__match() both of them will have 5 entries with pair set. And the second evsel has a collapsed entry so that the total number is 9 - I made it in order to simulate more realistic case. Thus after hists__link the first entry will have 14 entries - 5 are common (w/ pair), 5 are unmatch (w/o pair) and 4 are dummy (w/ pair). And the second entry will have 9 entries all have its pair.
