2015-11-03lib/tests: Add igt_assert_*() self-testsDaniel Stone
Make sure our igt_assert variants are doing something that looks vaguely like the right thing. Signed-off-by: Daniel Stone <daniels@collabora.com>
2015-09-24lib/tests: explicitly raise SIGSEGVThomas Wood
Dereferencing a NULL pointer is undefined behaviour and may not always result in a segmentation fault. Explicitly raise the SIGSEGV signal to test handling of this signal. v2: include signal.h (Derek Morton) Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2015-08-13benckmarks/Android.mk: Fix building benchmarks for AndroidDerek Morton
The commit "benchmarks: Do not install to system-wide bin/" changed the benchmark file list from bin_PROGRAMS to benchmarks_PROGRAMS. However Android.mk was not updated, resulting in IGT failing to build for Android. This commit adds that change. It also adds LOCAL_MODULE_PATH to specify where the built benchmarks should be put. v2: I discovered that the existing definitions of LOCAL_MODULE_PATH were creating what should have been an invalid path. Not sure how it was ever working previously, but fixed now. Signed-off-by: Derek Morton <derek.j.morton@intel.com> Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2015-08-12lib/core: Add optional reason for timeout failureDaniel Vetter
"Timed out" isn't a terribly informative message, allow users to set something more informative. Inspired by a request from Jesse. Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
2015-07-19igt/stats: Fixup tests to compile after interface changesChris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-07-02build: Add DEBUG_FLAGS to tools and self-testsDamien Lespiau
Makes using GDB better on those binaries. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Exercise the reallocation pathsDamien Lespiau
Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Spwan igt_init_with_size() from igt_init()Damien Lespiau
It's all about good looking APIs. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Test we do correctly invalidate the sorted arrayDamien Lespiau
Chris had a doubt, and I was lazy and didn't do a similar test for the quartiles/median than for the mean (test_invalidate_mean()). Plug that gap. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Add support for the interquartile range (IQR)Damien Lespiau
IQR is a good measure of dispersion. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Add support for quartiles (and thus median)Damien Lespiau
More stuff, quite useful characteristics of a dataset. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Use igt_assert_eq_double() when asserting on doublesDamien Lespiau
Lucky enough to have exact values, == works! Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Add igt_stats_get_range()Damien Lespiau
Somewhat useful, for instance to size an histogram. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Add functions to retrieve min/max values of the datasetDamien Lespiau
Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Factor out a fixture to initialize statsDamien Lespiau
We're going to use this simple fixture once more, might as well make a function instead of copy/pasting code. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Add a getter for the population propertyDamien Lespiau
Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Add a way to specify if the data set is a population or a sampleDamien Lespiau
This changes how we compute the variance. We want an unbiased variance when reasoning about a sample. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Zero the whole structure at init() timeDamien Lespiau
Because the structure started small, I initialized every member directly, but that means that the new fields added weren't properly initialized (sigh!). Zero the whole thing first then. Also, the punishment for introducing a bug should be to write the corresponding unit test. It's not a perfect one, but I'll take it. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27tests/stats: Make sure we properly invalidate the cached meanDamien Lespiau
Sure, that's an implementation details, but make sure we do recompute the mean when we add a new value. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Add a way to retrieve the standard deviationDamien Lespiau
Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27tests/igt_stats: Call igt_stats_fini() to not leak the arrayDamien Lespiau
Sure, it'll be freed at exit(), but might as well be a bit pedantic. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-27stats: Be more precise and talk about mean, not averageDamien Lespiau
There are several types of averages eg. mean, median and mode. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-25lib: Add a tiny utility function to compute averagesDamien Lespiau
The master plan would be to get a bit more stats in it, at least the standard deviation and confidence interval. Just need the average for now. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>
2015-06-15lib/tests/igt_segfault Add unit test to test segfault handlingDerek Morton
Unit test to check a segfaulting subtest is handled correctly. v2: Added script to check subtest results v3: Removed script. Updated test to use fork to monitor return status. v4: Added igt_segfault to .gitignore Signed-off-by: Derek Morton <derek.j.morton@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2015-05-27lib: Enable building unit tests on androidDerek Morton
Add a make file for android so the unit tests can be built. Enabled asserts for the library code so the unit test behaviour is correct. Signed-off-by: Derek Morton <derek.j.morton@intel.com> Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2015-04-14tests: create a single combined test listThomas Wood
All tests now respond in a consistent way such that separate lists for tests with and without subtests are no longer necessary. v2: fix other references to the test list Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2015-04-14lib: use test failure status for igt_set_timeoutThomas Wood
Use a failure status code for timeout to avoid confusion between tests that take too long to execute versus a failure due to an operation taking longer than expected. v2: Add a "timed out" message before exiting. (Daniel Vetter) Fix the timeout library check by disabling hard errors in xfail tests, since these share the same exit status as test failure. Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2015-03-30lib/tests: add missing library flagsThomas Wood
Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2015-02-25lib/tests: update .gitignoreThomas Wood
2015-02-25lib: remove handled option arguments from argvThomas Wood
Remove options from argv that have been handled by getopt to allow additional non-option parameters to be processed in the test application. This fixes issues when using options such as --debug with tests that accept additional non-option parameters. Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2015-02-09lib/tests: check that invalid subtest names are rejectedThomas Wood
Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2015-02-09lib/tests: verify subtest enumeration outputThomas Wood
Check that the subtest list is not empty if using --list-subtests returns with an exit code of 0, and that the list is empty if it returns with 79. Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2014-11-25lib: ensure subtests are not added to simple testsThomas Wood
Simple tests do not support subtests, so fail if igt_subtest is used in one. Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2014-11-13lib/tests: add a test for igt_set_timeoutThomas Wood
Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2014-11-06lib/tests: don't use hard error status to indicate test failureThomas Wood
An exit status of 99 is reported separately in the test summary as an error, rather than as a test failure. Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2014-11-06lib/tests: fix tests and test list locationThomas Wood
The igt_command_line.sh script was moved by commit 685e577 (Move library selftests to lib/tests), but the location of the tests and the test lists was not updated. Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2014-10-29lib/tests: use the "check_" prefix for testsThomas Wood
The "check_" prefix ensures the test programs are not installed and are only built when "make check" is run. Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2014-10-29build: fix distcheckThomas Wood
Fix distcheck issues introduced by commit 685e577 (Move library selftests to lib/tests). Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2014-10-29Move library selftests to lib/testsDaniel Vetter
Again they're not really igt testcases so are in the way of running spatch unconditionally. Move them someplace else. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
