"#" is understood to be diagnostics about the currently running test. Since there's no "---" nor "..." here, and the other parsers were pretty busted to try to parse YAML without those, I can be convinced that diagnostics can be marked with a leading " ", but if that's true, why not just drop all "#" usage? Then we'd have: TAP version 13 1..1 # Subtest: selftests: ptrace: get_syscall_info TAP version 13 1..1 Starting 1 tests from 1 test cases. RUN global.get_syscall_info ... OK global.get_syscall_info ok 1 global.get_syscall_info PASSED: 1 / 1 tests passed.

All I see is that now the test and the runner are once again mixing the responsibility of generating the test output.

This patch is part of a series to alter the format of kselftest TAP results to improve compatibility with proposed KTAP specification (https://lore.kernel.org/linux-kselftest/CA+GJov6tdjvY9x12JsJT14qn6c7NViJxqaJk+r-K1YJzPggFDQ@mail.gmail.com/). Two changes: - Change from "# " to " " for indentation of nested tests - Add subtest header line at start of tests with subtests. Line format is "# Subtest: [name of test]". An example of the new format: Old format: TAP version 13 1..1 # TAP version 13 # 1..1 # # Starting 1 tests from 1 test cases. # # RUN global.get_syscall_info ... # # OK global.get_syscall_info # ok 1 global.get_syscall_info # # PASSED: 1 / 1 tests passed. # # Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0 ok 1 selftests: ptrace: get_syscall_info New format: TAP version 13 1..1 # Subtest: selftests: ptrace: get_syscall_info TAP version 13 1..1 # Starting 1 tests from 1 test cases. # RUN global.get_syscall_info ... # OK global.get_syscall_info ok 1 global.get_syscall_info # PASSED: 1 / 1 tests passed. # Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0 ok 1 selftests: ptrace: get_syscall_info Signed-off-by: Rae Moar <rmoar@google.com> Change-Id: I139774745310ad2cd6dc5d7740254e48d8226241 --- tools/testing/selftests/kselftest/prefix.pl | 2 +- tools/testing/selftests/kselftest/runner.sh | 6 +++--- 2 files changed, 4 insertions(+), 4 deletions(-)
