Subject: [PATCH v2 0/8] selftests: Move test output to diagnostic lines
Date: Wed, 24 Apr 2019 16:12:29 -0700	[thread overview]
Message-ID: <20190424231237.14776-1-keescook@chromium.org> (raw)

This refactors the selftest Makefiles to extract the test running logic
to be reused between "run_tests" and "emit_tests", while also fixing
up the test output to be TAP version 13 compliant:
- added "plan" line
- fixed result line syntax
- moved all test output to be "# "-prefixed as TAP "diagnostic" lines

The prefixing code includes a fallback mode for limited execution
environments.

Additionally, the plan lines are fixed for all callers of kselftest.h.

-Kees

v2:
- fix external make variable "summary=1" through-out series (shuah)
- fix plan line output for all kselftest.h users

  selftests: Extract single-test shell logic from lib.mk
  selftests: Use runner.sh for emit targets
  selftests: Extract logic for multiple test runs
  selftests: Add plan line and fix result line syntax
  selftests: Distinguish between missing and non-executable
  selftests: Move test output to diagnostic lines
  selftests: Remove KSFT_TAP_LEVEL
  selftests: Add test plan API to kselftest.h and adjust callers
