Hello,
currently there are two issues with build-aux/test-driver.scm.
1. :test-global-result: is mistyped as :global-test-result:.
2. Summarizing metadata are outputted on end of each test-group, meaning they
will be present multiple times, if there is more than one test group.
First is somewhat fine, since, per the manual page, unknown keys are (for now)
ignored. However second is explicitly stated to be undefined behavior, so it
should be fixed.
I am CC-ing both authors listed in the test-driver.scm, since I have no idea
where the upstream is (it seems to be just copied around between projects?).
You can find fixes for the first (0001) and second (0002) issues attached to
this email.
I am also including two additional patches (0003 refining :test-global-result:
for XPASS as XXX mentioned, 0005 improving support for test group since it was
somewhat lacking) which I consider useful and I have applied them to my local
copy of test-driver.scm file. Feel free to apply them, or ignore them, as you
see fit.
Have a nice day,
Tomas Volf

According to the manual page, the correct metadata key is :test-global-result:
instead of the current :global-test-result:.

Subject: [PATCH 2/5] build: test-driver.scm: Output singleton metadata just
once.
Current implementation printed metadata supposed to be present just once per
.trs file on the end of each test group. According to the automake's manual
that is undefined behavior. This commit fixes it by printing that metadata
just once, after all tests did run.
Since there is no built-in hook that could be used for
that (test-runner-on-final runs on *each* outermost test-end), I introduced
new `finalize' procedure that need to be called by the user. Possibly not the
most elegant solution, but since we are the only user, it works fine and
produces actually valid .trs file.
That also means there is no longer any use for test-runner-on-test-end!.
* build-aux/test-driver.scm (test-runner-gnu): Define new procedure `finalize'
and return it together with the runner. Do not call
test-runner-on-group-end!.
(main): Call the `finalize' after all tests are done.

Subject: [PATCH 3/5] build: test-driver.scm: Refine the global test result.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The :test-global-result: .trs metadata contained just either FAIL, SKIP or
PASS with a comment that further refinements are required for XPASS. The
description of :test-global-result: is in the manual is as follows:
This is used to declare the "global result" of the script.
Currently, the value of this field is needed only to be reported
(more or less verbatim) in the generated global log file
‘$(TEST_SUITE_LOG)’, so it’s quite free-form. For example, a test
script which runs 10 test cases, 6 of which pass and 4 of which are
skipped, could reasonably have a ‘PASS/SKIP’ value for this field,
while a test script which runs 19 successful tests and one failed
test could have an ‘ALMOST PASSED’ value.
As we can see, the examples as `PASS/SKIP' and `ALMOST PASSED', so there is no
need to stick to strict model. Hence this commit changes the resulting value
to be comma-separated list of PASS, FAIL, XPASS, XFAIL and SKIP. The
respective elements are present only when the count of tests with such a
result is positive.
In practice, that should usually produce lines such as
:test-global-result: PASS,FAIL
or
:test-global-result: PASS
* build-aux/test-driver.scm (test-runner-gnu)[finalize]: Refine the output of
:test-global-result:.

Subject: [PATCH 5/5] build: test-driver.scm: Utilize test-runner-group-path.
Test groups were not used in any meaningful way. The group path was not
printed and it was not used in test selection mechanism. I think groups are
useful, and it is nice to be able to, for example, run tests from a single
group.
This commit does two things. First, it changes the test reporting to include
the value returned from test-runner-group-path, so you will know not only the
test name, but the test group(s) as well. And second, it changes the test
selection (and exclusion) process to match against the "full" test name, so
group path + test name.
Hence
(test-begin "failing tests")
(test-equal "this should fail" 1 2)
(test-end)
will, depending on the output location, produce following text.
.trs:
:test-result: FAIL failing tests: this should fail [0.000s]
:test-global-result: FAIL
:recheck: yes
:copy-in-global-log: yes
.log:
test-name: failing tests: this should fail
location: test.scm:140
source:
+ (test-equal "this should fail" 1 2)
expected-value: 1
actual-value: 2
result: FAIL
stdout:
FAIL: test.scm - failing tests: this should fail [0.000s]
* build-aux/test-driver.scm (current-test-full-name): New procedure.
(test-runner-gnu): Use current-test-full-name instead of
test-runner-test-name.
(test-match-name*): Match against current-test-full-name.
