2015-10-30test: facilitate debugging Git executables in tests with gdbLibravatar Johannes Schindelin1-0/+5
When prefixing a Git call in the test suite with 'debug ', it will now be run with GDB, allowing the developer to debug test failures more conveniently.

2015-03-20t/test-lib: introduce --chain-lint optionLibravatar Jeff King1-0/+10
It's easy to miss an "&&"-chain in a test script, like: test_expect_success 'check something important' ' cmd1 && cmd2 cmd3 ' The test harness will notice if cmd3 fails, but a failure of cmd1 or cmd2 will go unnoticed, as their exit status is lost after cmd3 runs. The toy example above is easy to spot because the "cmds" are all the same length, but real code is much more complicated. It's also difficult to detect these situations by statically analyzing the shell code with regexps (like the check-non-portable-shell script does); there's too much context required to know whether a &&-chain is appropriate on a given line or not. This patch instead lets the shell check each test by sticking a command with a specific and unusual return code at the top of each test, like: (exit 117) && cmd1 && cmd2 cmd3 In a well-formed test, the non-zero exit from the first command prevents any of the rest from being run, and the test's exit code is 117. In a bad test (like the one above), the 117 is lost, and cmd3 is run. When we encounter a failure of this check, we abort the test script entirely. For one thing, we have no clue which subset of the commands in the test snippet were actually run. Running further tests would be pointless, because we're now in an unknown state. And two, this is not a "test failure" in the traditional sense. The test script is buggy, not the code it is testing. We should be able to fix these problems in the script once, and not have them come back later as a regression in git's code. After checking a test snippet for --chain-lint, we do still run the test itself. We could actually have a pure-lint mode which just checks each test, but there are a few reasons not to. One, because the tests are executing arbitrary code, which could impact the later environment (e.g., that could impact which set of tests we run at all). And two, because a pure-lint mode would still be expensive to run, because a significant amount of code runs outside of the test_expect_* blocks. Instead, this option is designed to be used as part of a normal test suite run, where it adds very little overhead. Turning on this option detects quite a few problems in existing tests, which will be fixed in subsequent patches. However, there are a number of places it cannot reach: - it cannot find a failure to break out of loops on error, like: cmd1 && for i in a b c; do cmd2 $i done && cmd3 which will not notice failures of "cmd2 a" or "cmd b" - it cannot find a missing &&-chain inside a block or subfunction, like: foo () { cmd1 cmd2 } foo && bar which will not notice a failure of cmd1. - it only checks tests that you run; every platform will have some tests skipped due to missing prequisites, so it's impossible to say from one run that the test suite is free of broken &&-chains. However, all tests get run by _somebody_, so eventually we will notice problems. - it does not operate on test_when_finished or prerequisite blocks. It could, but these tends to be much shorter and less of a problem, so I punted on them in this patch. This patch was inspired by an earlier patch by Jonathan Nieder: http://article.gmane.org/gmane.comp.version-control.git/235913 This implementation and all bugs are mine.

We require use of test_must_fail to check expected non-zero exit by Git itself, but discourage test_must_fail to be used for checking exit status of non Git commands that are supplied by the system.

2014-10-13test-lib.sh: support -x option for shell-tracingLibravatar Jeff King1-0/+6
Usually running a test under "-v" makes it clear which command is failing. However, sometimes it can be useful to also see a complete trace of the shell commands being run in the test. You can do so without any support from the test suite by running "sh -x tXXXX-foo.sh". However, this produces quite a large bit of output, as we see a trace of the entire test suite. This patch instead introduces a "-x" option to the test scripts (i.e., "./tXXXX-foo.sh -x"). When enabled, this turns on "set -x" only for the tests themselves. This can still be a bit verbose, but should keep things to a more manageable level. You can even use "--verbose-only" to see the trace only for a specific test. The implementation is a little invasive. We turn on the "set -x" inside the "eval" of the test code. This lets the eval itself avoid being reported in the trace (which would be long, and redundant with the verbose listing we already showed). And then after the eval runs, we do some trickery with stderr to avoid showing the "set +x" to the user. We also show traces for test_cleanup functions (since they can impact the test outcome, too). However, we do avoid running the noop ":" cleanup (the default if the test does not use test_cleanup at all), as it creates unnecessary noise in the "set -x" output.

2013-10-29t: provide a perl() function which uses $PERL_PATHLibravatar Jeff King1-4/+8
Once upon a time, we assumed that calling a bare "perl" in the test scripts was OK, because we would find the perl from the user's PATH, and we were only asking that perl to do basic operations that work even on old versions of perl. Later, we found that some systems really prefer to use $PERL_PATH even for these basic cases, because the system perl misbehaves in some way (e.g., by handling line endings differently). We then switched "perl" invocations to "$PERL_PATH" to respect the user's choice. Having to use "$PERL_PATH" is ugly and cumbersome, though. Instead, let's provide a perl() shell function that tests can use, which will transparently do the right thing. Unfortunately, test writers still have to use $PERL_PATH in certain situations, so we still need to keep the advice in the README. Note that this may fix test failures in t5004, t5503, t6002, t6003, t6300, t8001, and t8002, depending on your system's perl setup. All of these can be detected by running: ln -s /bin/false bin-wrappers/perl make test which fails before this patch, and passes after.

2013-10-28t/README: tests can use perl even with NO_PERLLibravatar Jonathan Nieder1-4/+11
The git build system supports a NO_PERL switch to avoid installing perl bindings or other features (like "git add --patch") that rely on perl on runtime, but even with NO_PERL it has not been possible for a long time to run tests without perl. Helpers such as nul_to_q () { "$PERL_PATH" -pe 'y/\000/Q/' } use perl as a better tr or sed and are regularly used in tests without worrying to add a PERL prerequisite. Perl is portable enough that it seems fine to keep relying on it for this kind of thing in tests (and more readable than the alternative of trying to find POSIXy equivalents). Update the test documentation to clarify this. Reported-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

With the new --verbose-only=<pattern> option, one can enable --verbose at a per-test granularity. The pattern is matched against the test number, e.g. ./t0000-basic.sh --verbose-only='2[0-2]' to see only the full output of test 20-22, while showing the rest in the one-liner format. As suggested by Jeff King, this takes care to wrap the entire test_expect_* block, but nothing else, in the verbose toggling. We can use the test_start/end functions from the previous commit for the purpose. This is arguably not *too* useful on its own, but makes the next patch easier to follow.

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.

2010-08-18t/README: Update "Skipping tests" to align with best practicesLibravatar Ævar Arnfjörð Bjarmason1-3/+18
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.

2010-08-18t/README: Add a note about the dangers of coverage chasingLibravatar Ævar Arnfjörð Bjarmason1-0/+9
Having no coverage at all is almost always a bad sign, but trying to attain 100% coverage everywhere is usually a waste of time. Add a paragraph to explain this to future test writers.
