t5000-tar-tree.sh failing

Hello,

when I run make test, I get:

*** t5000-tar-tree.sh ***

I think the problem is:

	zeisberg@cepheus:~/gsrc/git$ unzip
	bash: unzip: command not found

Probably the subversion tests suffer the same (for svn instead of unzip).

Do we want the tests to depend on all that or would it be sensible to output a warning that a program is missing? Or maybe introduce test "13.5: check is unzip is available". Then it would be more obvious for the tester what went wrong?

Hi,

Yep. That's the problem.

Why not enclose the tests in a

if unzip -h >/dev/null 2>/dev/null; then

# all these tests

fi

Hmm?

Several other test frameworks provide a "skip" method to indicate why we've skipped something. We could do something similar...

if skip 'unzip -h' 'tests need unzip'; then

   # unzip tests
fi

skip() {
# Have not checked to see if this is anything resembling working code if eval $1 > /dev/null 2>&1; then
true
else

    echo "* skipping tests: $2" 1>&2
    false

fi
}

Mostly so that skipped tests are obvious, provide a reason, and have a standardized display format. Again, too busy in actual work to try to do this myself right now, but might hack at it this afternoon if nobody else (hopefully someone more fluent in shell than I am) does.

Hello,

I'm not sure if (in this case) a missing unzip should be as silent as you suggest. The danger is, that s.o. makes a change, runs make test and is then conviced that nothing broke. So I think that the test should fail, but with a more descriptive error than it is now.

The downside is, you need unzip, svn, what ever more to run the test suite.

I was attempting to say that if we're skipping tests we should say so, and not just drop them silently like the code that Johannes posted. Really, I guess the ideal would be for there to be a test harness that would run all the tests and report skips and errors in a report at the end rather than in the middle.

Hi,

Well, the tests are not distributed with the binary packages. For a reason. The maintainer of the binary packages has to check if the tests succeed. An she better know what she's doing!

So, if Joe Average compiles git, does not have unzip installed, and runs the tests, chances are that he does not want to be bothered about the zip tests failing because of the absence of unzip.

Sorry. Does not work here. I _only_ look at the messages if the test suite fails somewhere, with a loud error message at the end.
