From: Geliang Tang <tanggeliang@kylinos.cn>
This patch adds two vars in mptcp_lib.sh, MPTCP_LIB_TEST_COUNTER for
the test counter and MPTCP_LIB_TEST_FORMAT for the test print format.
Also add two helpers, mptcp_lib_inc_test_counter(), increase the test
counter, and mptcp_lib_pr_title_counter(), print the test title with
counter. They are used in mptcp_join.sh first.

Please add the reason, something like: Each MPTCP selftest is having
subtests, and it helps to give them a number to quickly identify them.
This can be managed by mptcp_lib.sh, reusing what has been done here.
The following commit will use these new helpers in the other tests.

No need to re-set it all the time, this line can be moved just before
"sourcing" mptcp_lib.sh I think, with a comment like:
# Here, we have more than 100 tests, having multiple checks
MPTCP_LIB_TEST_FORMAT="%03u %s\n"
. "$(dirname "${0}")/mptcp_lib.sh"

Can you declare them at the top, around the other ones?
(MPTCP_LIB_SUBTESTS, etc.)
And I think you should set the default value there too, like what I was
suggesting in patch 07/12 from v5:
: "${MPTCP_LIB_TEST_FORMAT:="%02u %-50s"}"
MPTCP_LIB_TEST_COUNTER=0
So we can change the format by setting MPTCP_LIB_TEST_FORMAT before
"sourcing" mptcp_lib.sh.
No?
*If* we need to alter the format just for one title, we can always do:
MPTCP_LIB_TEST_FORMAT="..." \
mptcp_lib_pr_title_counter "<title>"
But best to avoid that.

I don't think that's needed, it has been defined in the file, no?

Please always justify why you need to ignore a rule.
Also, always try to reduce the scope as much as possible: just for one
line, for one function, for the whole file → here, move it just before
calling 'printf':
# shellcheck disable=SC2059 # the format is in a variable
printf "${MPTCP_LIB_TEST_FORMAT}" (...)
(and add a space after '#')

I didn't check: can you not print the title and increment the counter
(via mptcp_lib_inc_test_counter) from here? I think that would be a good
practice to do that instead of having to deal with the counter in
different places.
We would only call "mptcp_lib_inc_test_counter()" from other scripts
when a test is skipped.

OK, I just saw you added mptcp_lib_print_title() in the next patch. Why
did you not use it for mptcp_join.sh?
Can you not call "mptcp_lib_inc_test_counter" in the "if skip_test" from
mptcp_join.sh and use mptcp_lib_print_title()? (if you do that, I guess
we don't need mptcp_lib_pr_title_counter(), no?)

Yes, I dropped mptcp_lib_pr_title_counter in v9.

Mmh, we can also simply set it here:
MPTCP_LIB_TEST_FORMAT="%02u %-50s"
MPTCP_LIB_TEST_COUNTER=0
And users of the lib can override it after having "sourced"
mptcp_lib.sh, along with other "global" variables set at the beginning
of the file (with a comment justifying why we need to alter the format).
