Jonathan Nieder fb3340a6a7 test-lib: introduce test_line_count to measure files
Some tests check their output with code like the following:

	test "$(git ls-files -u B | wc -l)" -eq 3 || {
		echo "BAD: should have left stages for B"
		return 1
	}

The verbose failure condition is used because test, unlike
diff, does not print any useful information about the
nature of the failure when it fails.

Introduce a test_line_count function to help. If used like

	git ls-files -u B >output &&
	test_line_count -eq 3 output

it will produce output like

	test_line_count: line count for output !-eq 3
	100644 b023018cabc396e7692c70bbf5784a93d3f738ab 2	hi.c
	100644 45b983be36b73c0788dc9cbcb76cbb80fc7bb057 3	hi.c

on failure.

Ævar Arnfjörð Bjarmason 892e6f7ea6 test-lib: make test_expect_code a test command
Change test_expect_code to be a normal test command instead of a
top-level command.

As a top-level command it would fail in cases like:

    test_expect_code 1 'phoney' '
        foo && bar && (exit 1)
    '

Here the test might incorrectly succeed if "foo" or "bar" happened to
fail with exit status 1. Instead we now do:

    test_expect_success 'phoney' '
        foo && bar && test_expect_code 1 "(exit 1)"
    '

Which will only succeed if "foo" and "bar" return status 0, and "(exit
1)" returns status 1.  Note that test_expect_code has been made slightly
noisier, as it reports the exit code it receives even upon success.

Some test code in t0000-basic.sh relied on the old semantics of
test_expect_code to test the test_when_finished command. I've
converted that code to use an external test similar to the TODO test I
added in v1.7.3-rc0~2^2~3.

Ævar Arnfjörð Bjarmason 99d9050d25 t/README: Update "Skipping tests" to align with best practices
The example I initially added to "Skipping tests" wasn't very
good. We'd rather skip tests using the three-arg prereq form to the
test_* functions, not bail out with a skip message.

Change the documentation to reflect that, but retain the bailout
example under a disclaimer which explains that it's probably not a
good idea to use it.

Ævar Arnfjörð Bjarmason c91cfd1916 tests: A SANITY test prereq for testing if we're root
Some tests depend on not being able to write to files after chmod
-w. This doesn't work when running the tests as root.

Change test-lib.sh to test if this works, and if so it sets a new
SANITY test prerequisite. The tests that use this previously failed
when run under root.

There was already a test for this in t3600-rm.sh, added by Junio C
Hamano in 2283645 in 2006. That check now uses the new SANITY
prerequisite.

Some of this was resurrected from the "Tests in Cygwin" thread in May
2009:

Thad had to be fixed in 335f87871f when

Ævar Arnfjörð Bjarmason 5099b99d25 test-lib: Adjust output to be valid TAP format
TAP, the Test Anything Protocol, is a simple text-based interface
between testing modules in a test harness. test-lib.sh's output was
already very close to being valid TAP. This change brings it all the
way there. Before:

    $ ./t0005-signals.sh
    *   ok 1: sigchain works
    * passed all 1 test(s)

And after:

    $ ./t0005-signals.sh
    ok 1 - sigchain works
    # passed all 1 test(s)
    1..1

The advantage of using TAP is that any program that reads the format
(a "test harness") can run the tests. The most popular of these is the
prove(1) utility that comes with Perl. It can run tests in parallel,
display colored output, format the output to console, file, HTML etc.,
and much more. An example:

    $ prove ./t0005-signals.sh
    ./t0005-signals.sh .. ok
    All tests successful.
    Files=1, Tests=1,  0 wallclock secs ( 0.03 usr  0.00 sys +  0.01 cusr  0.02 csys =  0.06 CPU)
    Result: PASS

prove(1) gives you human readable output without being too
verbose. Running the test suite in parallel with `make test -j15`
produces a flood of text. Running them with `prove -j 15 ./t[0-9]*.sh`
makes it easy to follow what's going on.

All this patch does is re-arrange the output a bit so that it conforms
with the TAP spec, everything that the test suite did before continues
to work. That includes aggregating results in t/test-results/, the
--verbose, --debug and other options for tests, and the test color
output.

TAP harnesses ignore everything that they don't know about, so running
the tests with --verbose works:

    $ prove ./t0005-signals.sh :: --verbose --debug
    ./t0005-signals.sh .. Terminated
    ./t0005-signals.sh .. ok
    All tests successful.
    Files=1, Tests=1,  0 wallclock secs ( 0.02 usr  0.01 sys +  0.01 cusr  0.01 csys =  0.05 CPU)
    Result: PASS

Just supply the -v option to prove itself to get all the verbose
output that it suppresses:

    $ prove -v ./t0005-signals.sh :: --verbose --debug
    ./t0005-signals.sh ..
    Initialized empty Git repository in /home/avar/g/git/t/trash directory.t0005-signals/.git/
    expecting success:
            test-sigchain >actual
            case "$?" in
            143) true ;; # POSIX w/ SIGTERM=15
              3) true ;; # Windows
              *) false ;;
            esac &&
            test_cmp expect actual
    Terminated
    ok 1 - sigchain works
    # passed all 1 test(s)
    1..1
    ok
    All tests successful.
    Files=1, Tests=1,  0 wallclock secs ( 0.02 usr  0.00 sys +  0.01 cusr  0.01 csys =  0.04 CPU)
    Result: PASS

As a further example, consider this test script that uses a lot of
test-lib.sh features by Jakub Narebski:

    #!/bin/sh

    test_description='this is a sample test.

    This test is here to see various test outputs.'

    . ./test-lib.sh

    say 'diagnostic message'

    test_expect_success 'true  test' 'true'
    test_expect_success 'false test' 'false'

    test_expect_failure 'true  test (todo)' 'true'
    test_expect_failure 'false test (todo)' 'false'

    test_debug 'echo "debug message"'

    test_done

The output of that was previously:

    * diagnostic message                      # yellow
    *   ok 1: true  test
    * FAIL 2: false test                      # bold red
            false
    *   FIXED 3: true  test (todo)
    *   still broken 4: false test (todo)     # bold green
    * fixed 1 known breakage(s)               # green
    * still have 1 known breakage(s)          # bold red
    * failed 1 among remaining 3 test(s)      # bold red

But is now:

    diagnostic message                                    # yellow
    ok 1 - true  test
    not ok - 2 false test                                 # bold red
    #       false

Johannes Schindelin 44138559e8 test-lib.sh: optionally output to test-results/$TEST.out, too
When tests are run in parallel and a few tests fail, it does not help
that the output of the terminal is totally confusing, as you rarely know
which test which line came from.

So introduce the option '--tee' which triggers that the output of the
tests will be written to t/test-results/$TEST.out in addition to the
terminal, where $TEST is the basename of the script.

Unfortunately, there seems to be no way to redirect a given file
descriptor to a specified subprocess in POSIX shell, only redirection
to a file is supported via 'exec > $FILE'.

At least with bash, one might think that 'exec >($COMMAND)' would work
as intended, but it does not.

The common way to work around the lack of proper tools support is to
work with named pipes, alas, one of our most beloved platforms does not
really support named pipes.  Besides, we would need a pipe for every
script, as the whole point of this patch is to allow parallel execution.

Therefore, we handle the redirection in the following way: when '--tee'
was passed to the test script, the variable GIT_TEST_TEE_STARTED is set
(to avoid triggering that code path again) and the script is started
_again_, in a subshell, redirected to the command "tee".

Johannes Schindelin 4e1be63c3b Add valgrind support in test scripts
This patch adds the ability to use valgrind's memcheck tool to
diagnose memory problems in Git while running the test scripts.

It requires valgrind 3.4.0 or newer.

It works by creating symlinks to a valgrind script, which have the same
name as our Git binaries, and then putting that directory in front of
the test script's PATH as well as set GIT_EXEC_PATH to that directory.
Git scripts are symlinked from that directory directly.

That way, Git binaries called by Git scripts are valgrinded, too.

Valgrind can be used by specifying "GIT_TEST_OPTS=--valgrind" in the
make invocation. Any invocation of git that finds any errors under
valgrind will exit with failure code 126. Any valgrind output will go
to the usual stderr channel for tests (i.e., /dev/null, unless -v has
been specified).

If you need to pass options to valgrind -- you might want to run
another tool than memcheck, for example -- you can set the environment
variable GIT_VALGRIND_OPTIONS.

A few default suppressions are included, since libz seems to trigger
quite a few false positives. We'll assume that libz works and that we
can ignore any errors which are reported there.

Note: it is safe to run the valgrind tests in parallel, as the links in
t/valgrind/bin/ are created using proper locking.

Initial patch and all the hard work by Jeff King.

Johannes Schindelin 008849689e test-lib.sh: introduce test_commit() and test_merge() helpers
Often we just need to add a commit with a given (short) name, that will
be tagged with the same name.  Now, relatively complicated graphs can be
constructed easily and in a clear fashion:

	test_commit A &&
	test_commit B &&
	git checkout A &&
	test_commit C &&
	test_merge D B

will construct this graph:

	A - B
	  \   \
	    C - D

For simplicity, files whose name is the lower case version of the commit
message (to avoid a warning about ambiguous names) will be committed, with
the corresponding commit messages as contents.

If you need to provide a different file/different contents, you can use
the more explicit form

	test_commit $MESSAGE $FILENAME $CONTENTS

Lea Wiemann 5e2c08c6f0 test-lib.sh: add --long-tests option
Add a --long-tests option to test-lib.sh, which enables tests to
selectively run more exhaustive (longer running, potentially
brute-force) tests.  Such exhaustive tests would only be useful if one
works on the specific module that is being tested -- for a general "cd
t/; make" to check whether everything is OK, such exhaustive tests
shouldn't be run by default since the longer it takes to run the
tests, the less often they are actually run.

Junio C Hamano 41ac414ea2 Sane use of test_expect_failure
Originally, test_expect_failure was designed to be the opposite
of test_expect_success, but this was a bad decision.  Most tests
run a series of commands that leads to the single command that
needs to be tested, like this:

    test_expect_{success,failure} 'test title' '
	setup1 &&
        setup2 &&
        setup3 &&
        what is to be tested
    '

And expecting a failure exit from the whole sequence misses the
point of writing tests.  Your setup$N that are supposed to
succeed may have failed without even reaching what you are
trying to test.  The only valid use of test_expect_failure is to
check a trivial single command that is expected to fail, which
is a minority in tests of Porcelain-ish commands.

This large-ish patch rewrites all uses of test_expect_failure to
use test_expect_success and rewrites the condition of what is
tested, like this:

    test_expect_success 'test title' '
	setup1 &&
        setup2 &&
        setup3 &&
        ! this command should fail
    '

test_expect_failure is redefined to serve as a reminder that
that test *should* succeed but due to a known breakage in git it
currently does not pass.  So if git-foo command should create a
file 'bar' but you discovered a bug that it doesn't, you can
write a test like this:

    test_expect_failure 'git-foo should create bar' '
        rm -f bar &&
        git foo &&
        test -f bar
    '

This construct acts similar to test_expect_success, but instead
of reporting "ok/FAIL" like test_expect_success does, the
outcome is reported as "FIXED/still broken".

Junio C Hamano 215a7ad1ef Big tool rename.
As promised, this is the "big tool rename" patch.  The primary differences
since 0.99.6 are:

  (1) git-*-script are no more.  The commands installed do not
      have any such suffix so users do not have to remember if
      something is implemented as a shell script or not.

  (2) Many command names with 'cache' in them are renamed with
      'index' if that is what they mean.

There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support  is expected to be removed in the near
future.
