Change KUnit test output to better comply with KTAP v1 specifications found here: https://kernel.org/doc/html/latest/dev-tools/ktap.html. 1) Use "KTAP version 1" instead of "TAP version 14" as test output header 2) Remove '-' between test number and test name on test result lines 2) Add KTAP version lines to each subtest header as well Note that the new KUnit output still includes the “# Subtest” line now located after the KTAP version line. This does not completely match the KTAP v1 spec but since it is classified as a diagnostic line, it is not expected to be disruptive or break any existing parsers. This “# Subtest” line comes from the TAP 14 spec (https://testanything.org/tap-version-14-specification.html) and it is used to define the test name before the results. Original output: TAP version 14 1..1 # Subtest: kunit-test-suite 1..3 ok 1 - kunit_test_1 ok 2 - kunit_test_2 ok 3 - kunit_test_3 # kunit-test-suite: pass:3 fail:0 skip:0 total:3 # Totals: pass:3 fail:0 skip:0 total:3 ok 1 - kunit-test-suite New output: KTAP version 1 1..1 KTAP version 1 # Subtest: kunit-test-suite 1..3 ok 1 kunit_test_1 ok 2 kunit_test_2 ok 3 kunit_test_3 # kunit-test-suite: pass:3 fail:0 skip:0 total:3 # Totals: pass:3 fail:0 skip:0 total:3 ok 1 kunit-test-suite Signed-off-by: Rae Moar <rmoar@xxxxxxxxxx> Reviewed-by: Daniel Latypov <dlatypov@xxxxxxxxxx> Reviewed-by: David Gow <davidgow@xxxxxxxxxx> --- Changes since v1: https://lore.kernel.org/all/20221104194705.3245738-1-rmoar@xxxxxxxxxx/ - Switch order of patches to make changes to the parser before making changes to the test output - Change location of the new KTAP version line in subtest header to be before the subtest header line lib/kunit/executor.c | 6 +++--- lib/kunit/test.c | 5 +++-- 2 files changed, 6 insertions(+), 5 deletions(-) diff --git a/lib/kunit/executor.c b/lib/kunit/executor.c index 9bbc422c284b..74982b83707c 100644 --- a/lib/kunit/executor.c +++ b/lib/kunit/executor.c @@ -166,7 +166,7 @@ static void kunit_exec_run_tests(struct suite_set *suite_set) { size_t num_suites = suite_set->end - suite_set->start; - pr_info("TAP version 14\n"); + pr_info("KTAP version 1\n"); pr_info("1..%zu\n", num_suites); __kunit_test_suites_init(suite_set->start, num_suites); @@ -177,8 +177,8 @@ static void kunit_exec_list_tests(struct suite_set *suite_set) struct kunit_suite * const *suites; struct kunit_case *test_case; - /* Hack: print a tap header so kunit.py can find the start of KUnit output. */ - pr_info("TAP version 14\n"); + /* Hack: print a ktap header so kunit.py can find the start of KUnit output. */ + pr_info("KTAP version 1\n"); for (suites = suite_set->start; suites < suite_set->end; suites++) kunit_suite_for_each_test_case((*suites), test_case) { diff --git a/lib/kunit/test.c b/lib/kunit/test.c index 90640a43cf62..19344cb501c5 100644 --- a/lib/kunit/test.c +++ b/lib/kunit/test.c @@ -149,6 +149,7 @@ EXPORT_SYMBOL_GPL(kunit_suite_num_test_cases); static void kunit_print_suite_start(struct kunit_suite *suite) { + kunit_log(KERN_INFO, suite, KUNIT_SUBTEST_INDENT "KTAP version 1\n"); kunit_log(KERN_INFO, suite, KUNIT_SUBTEST_INDENT "# Subtest: %s", suite->name); kunit_log(KERN_INFO, suite, KUNIT_SUBTEST_INDENT "1..%zd", @@ -175,13 +176,13 @@ static void kunit_print_ok_not_ok(void *test_or_suite, * representation. */ if (suite) - pr_info("%s %zd - %s%s%s\n", + pr_info("%s %zd %s%s%s\n", kunit_status_to_ok_not_ok(status), test_number, description, directive_header, (status == KUNIT_SKIPPED) ? directive : ""); else kunit_log(KERN_INFO, test, - KUNIT_SUBTEST_INDENT "%s %zd - %s%s%s", + KUNIT_SUBTEST_INDENT "%s %zd %s%s%s", kunit_status_to_ok_not_ok(status), test_number, description, directive_header, (status == KUNIT_SKIPPED) ? directive : ""); -- 2.38.1.584.g0f3c55d4c2-goog
