2017-08-25selftests: kselftest framework: change skip exit code to 0Shuah Khan1-1/+2
When a test is skipped, instead of using a special exit code of 4, treat it as pass condition and use exit code of 0. It makes sense to treat skip as pass since the test couldn't be run as opposed to a failed test. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
2017-08-09selftests: kselftest framework: add error counterShuah Khan1-3/+18
Some tests track errors in addition to test failures. Add ksft_error counter, ksft_get_error_cnt(), and ksft_test_result_error() API to get the counter value and print error message. Update ksft_print_cnts(), and ksft_test_num() to include error counter. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
2017-07-28selftests: kselftest framework: add API to return pass/fail/* countsShuah Khan1-0/+10
Some tests print final pass/fail message based on fail count. Add ksft_get_*_cnt() API to kselftest framework to return counts. Update ksft_print_cnts() to print the test results summary message with individual pass, fail, ... counters.

2015-05-26kselftest: Add exit code definesDarren Hart1-5/+12
Define the exit codes with KSFT_PASS and similar so tests can use these directly if they choose. Also enable harnesses and other tooling to use the defines instead of hardcoding the return codes.

2014-11-17selftests: add kselftest framework for uniform test reportingShuah Khan1-0/+62
Add kselftest framework for tests to use. This is a light weight framework provides a set of interfaces to report test results. Tests can use these interfaces to report pass, and fail cases as well as when failure is due to configuration problems such as missing modules, or when a test that is should fail, fails as expected, and a test that should fail, passes. The framework uses POSIX standard return codes for reporting results to address the needs of users that want to run the kernel selftests from their user-space test suites and want to know why a test failed. In addition, the framework includes interfaces to use to report test statistics on number of tests passed and failed. Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
