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 Reviewed-by: Daniel Latypov Reviewed-by: David Gow Reviewed-by: David Gow Tested-by: Anders Roxell --- Changes since v2: https://lore.kernel.org/all/20221121184743.1123556-2-rmoar@google.com/ - Made fixes discussed on the v2 patch to now correctly output test results after second level testing Changes since v1: https://lore.kernel.org/all/20221104194705.3245738-1-rmoar@google.com/ - 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/debugfs.c | 2 +- lib/kunit/executor.c | 6 +++--- lib/kunit/test.c | 9 ++++++--- 3 files changed, 10 insertions(+), 7 deletions(-) diff --git a/lib/kunit/debugfs.c b/lib/kunit/debugfs.c index 1048ef1b8d6e..de0ee2e03ed6 100644 --- a/lib/kunit/debugfs.c +++ b/lib/kunit/debugfs.c @@ -63,7 +63,7 @@ static int debugfs_print_results(struct seq_file *seq, void *v) kunit_suite_for_each_test_case(suite, test_case) debugfs_print_result(seq, suite, test_case); - seq_printf(seq, "%s %d - %s\n", + seq_printf(seq, "%s %d %s\n", kunit_status_to_ok_not_ok(success), 1, suite->name); return 0; } 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..1c9d8d962d67 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 : ""); @@ -542,6 +543,8 @@ int kunit_run_tests(struct kunit_suite *suite) /* Get initial param. */ param_desc[0] = '\0'; test.param_value = test_case->generate_params(NULL, param_desc); + kunit_log(KERN_INFO, &test, KUNIT_SUBTEST_INDENT KUNIT_SUBTEST_INDENT + "KTAP version 1\n"); kunit_log(KERN_INFO, &test, KUNIT_SUBTEST_INDENT KUNIT_SUBTEST_INDENT "# Subtest: %s", test_case->name); @@ -555,7 +558,7 @@ int kunit_run_tests(struct kunit_suite *suite) kunit_log(KERN_INFO, &test, KUNIT_SUBTEST_INDENT KUNIT_SUBTEST_INDENT - "%s %d - %s", + "%s %d %s", kunit_status_to_ok_not_ok(test.status), test.param_index + 1, param_desc);
