The verbose output of every test looks something like this:

  expecting success:
          echo content >file &&
          git add file &&
          git commit -m "add file"

  [master (root-commit) d1fbfbd] add file
   Author: A U Thor <author@example.com>
   1 file changed, 1 insertion(+)
   create mode 100644 file
  ok 1 - commit works

i.e. first an "expecting success" (or "checking known breakage") line
followed by the commands to be executed, then the output of those
comamnds, and finally an "ok"/"not ok" line containing the test name.
Note that the test's name is only shown at the very end.

With '-x' tracing enabled and/or in longer tests the verbose output
might be several screenfulls long, making it harder than necessary to
find where the output of the test with a given name starts (especially
when the outputs to different file descriptors are racing, and the
"expecting success"/command block arrives earlier than the "ok" line
of the previous test).

Print the test name at the start of the test's verbose output, i.e. at
the end of the "expecting success" and "checking known breakage"
lines, to make the start of a particular test a bit easier to
recognize.

So the dummy test above would start like this:

  expecting success of 'commit works':
          echo content >file &&
  [...]

I remember being annoyed by this every once in a while for years, and
https://public-inbox.org/git/20190802100956.GV20404@szeder.dev/
reminded me again to finally do something about it.

Maybe it would make sense to also mention the test and test case number,
like so?

	expecting success of t9876.54 'it works':

It's easy enough to do so, but I don't readily see any benefits.

The '--verbose-log' of each test script is written to a separate
file, whose name already contains the test number, so there is no use
including it for each test case in there.  When running a test script
and looking at its '--verbose' output, then surely all test numbers
must be from that particular test script, so there is no use, either.

As for the test case number, since the test cases are not numbered in
the test scripts, I just ignore them right away, and look for test
names anyway.

Could you give an example?

Oh, my common way to read test logs is to sift through CI builds' logs,
in particular for the branches on https://github.com/gitster/git that
are based on commits without support for the convenient Tests tab in
Azure Pipelines.

So I hit Ctrl+F and look for `not ok` in literally hundreds/thousands of
lines. Of course, this is already the unrolled log _only_ of the failed
test scripts. Still, it is no fun to scoll back from test case 64 all
the way to 1 just to find out which test script contains this particular
failed test case.

Include the test script number, test number, and the test name at the
start of the verbose output of each test, to help navigating the
tests' logs.

Changes since v1:

  - Include not only the test name, but the test script number and
    test number as well.

  - An additional small adjustment was necessary to 't0000-basic.sh',
    which I thought is better as a separate preparatory patch, to ease
    review a bit.

Our test scripts are named something like 't1234-command.sh', but the
script names used in 't0000-basic.sh' don't follow this naming
convention.  Normally this doesn't matter, because the test scripts
themselves don't care how they are called.  However, the next patch
will start to include the test number in the test's verbose output, so
the test script's name will matter in the two tests checking the
verbose output.

Update the tests 'test --verbose' and 'test --verbose-only' to follow
out test script naming convention.

Leave the other tests in 't0000' unchanged: changing the names of
their test scripts would be only pointless code churn.

  expecting success:
          echo content >file &&
          git add file &&
          git commit -m "add file"

i.e. first an "expecting success" (or "checking known breakage") line
followed by the commands to be executed, then the output of those
comamnds, and finally an "ok"/"not ok" line containing the test name.
Note that the test's name is only shown at the very end.

Print the test name at the start of the test's verbose output, i.e. at
the end of the "expecting success" and "checking known breakage"
lines, to make the start of a particular test a bit easier to
recognize.  Also print the test script and test case numbers, to help
those poor souls who regularly have to scan through the combined
verbose output of several test scripts.

So the dummy test above would start like this:
