This series of patches updates the format of kselftest TAP results to improve compatibility with the proposed KTAP specification (https://lore.kernel.org/linux-kselftest/CA+GJov6tdjvY9x12JsJT14qn6c7NViJxqaJ...).
Three 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]". - Remove TAP header in nested tests
Standardizing TAP results would not only allow for clearer documentation and ease of reading but by standardizing the format across different testing frameworks, we could also share the use of tools.
As an example:
This is a truncated version of TAP results from the kselftest ptrace with the new format changes:
TAP version 13 1..1 # selftests: ptrace: get_syscall_info # Subtest: selftests: ptrace: get_syscall_info 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
With the new patch to update the KUnit parser to improve compatibility with the proposed KTAP specification, (https://lore.kernel.org/linux-kselftest/20210826195505.3066755-1-rmoar@googl...) the above TAP results would be parsed as the following:
[20:46:09] ============================================================ [20:46:09] ===== selftests: ptrace: get_syscall_info (1 subtest) ====== [20:46:09] [PASSED] global.get_syscall_info [20:46:09] ======= [PASSED] selftests: ptrace: get_syscall_info ======= [20:46:09] ============================================================ [20:46:09] Testing complete. Passed: 1, Failed: 0, Crashed: 0, Skipped: 0, Errors: 0
Thus, the kunit parser could become a useful tool for kselftest users.
