Although "TAP" word is being used already in documentation, but it hasn't been defined in informative way for developers that how to write TAP conformant tests and what are the benefits. Write a short brief about it.

When there are multiple tests supported by a test suite, it doesn't make sense to convert every single print statement. That is the reason why we have the run_tests wrapper that prints the summary in TAP format.
I would rephrase this to say "should be used for pass, fail, exit, and skip messages".
This rule is applicable to only the tests that are in the selftests Makefile and included in the default run.
There is no need to convert every single print statement in tests.
- exit statements. CI systems can easily parse TAP output messages to
- detect test failures.
I would rather see people spending energy writing new tests and fixing warnings. TAP conversions need to be focused if they add value.

Makes sense. I'll update.

Some tests don't print pass/fail and just return status by exit value. Adding pass/fail statements there really add value by exposing what went wrong. So it can be reproduced in debug environment to fix it.
