selftest: include stdio.h in kselftest.h

2019-02-13T15:34:47Z

While playing around with a way to skip the seccomp get_metadata test, I noticed that this header uses printf() without defining it, leading to, ../kselftest.h: In function ‘ksft_print_header’: ../kselftest.h:61:3: warning: implicit declaration of function ‘printf’ [-Wimplicit-function-declaration] printf("TAP version 13\n"); ^~~~~~ ../kselftest.h:61:3: warning: incompatible implicit declaration of built-in function ‘printf’ ../kselftest.h:61:3: note: include ‘’ or provide a declaration of ‘printf’ if user code doesn't also use printf.

selftests: kselftest: change KSFT_SKIP=4 instead of KSFT_PASS

2018-05-30T21:21:52Z

KSFT_SKIP points to KSFT_PASS resulting in reporting skipped tests as Passed, when test programs exit with KSFT_SKIP or call ksft_exit_skip(). If tests are skipped because of unmet dependencies and/or unsupported configuration, reporting them as passed leads to too many false positives. Fix it to return a skip code of 4 to clearly differentiate the skipped tests. Signed-off-by: Shuah Khan (Samsung OSG)

selftests: kselftest framework: add handling for TAP header level

2018-03-06T02:10:27Z

Introduce environment variable KSFT_TAP_LEVEL to avoid printing nested TAP headers for each test. lib.mk run_tests target prints TAP header before invoking the test program or test script. Tests need a way to suppress TAP headers if it is already printed out. This new environment variable adds a way for ksft_print_header() print TAP header only when KSFT_TAP_LEVEL isn't set. lib.mk run_tests and test program should print TAP header and set KSFT_TAP_LEVEL to avoid a second TAP header to be printed. selftests Makefile should export KSFT_TAP_LEVEL and add TAP Header echo to the run_kselftest.sh script from emit_tests target handling.

selftests: kselftest framework: change skip exit code to 0

2017-08-25T16:02:00Z

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

selftests: kselftest framework: add error counter

2017-08-09T16:39:05Z

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

selftests: kselftest framework: add API to return pass/fail/* counts

2017-07-28T19:20:19Z

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. Signed-off-by: Shuah Khan Reviewed-by: Gustavo Padovan
