t0000-basic: modernize test format

2023-05-19T17:08:10Z

Some tests in t0000-basic.sh used the older four space indent format. Update these to use tabs. Signed-off-by: John Cai Signed-off-by: Junio C Hamano

tests: make 'test_oid' print trailing newline

2022-12-19T00:49:11Z

Unlike other test helper functions, 'test_oid' doesn't terminate its output with a LF, but, alas, the reason for this, if any, is not mentioned in 2c02b110da (t: add test functions to translate hash-related values, 2018-09-13)). Now, in the vast majority of cases 'test_oid' is invoked in a command substitution that is part of a heredoc or supplies an argument to a command or the value to a variable, and the command substitution would chop off any trailing LFs, so in these cases the lack or presence of a trailing LF in its output doesn't matter. However: - There appear to be only three cases where 'test_oid' is not invoked in a command substitution: $ git grep '\stest_oid ' -- ':/t/*.sh' t0000-basic.sh: test_oid zero >actual && t0000-basic.sh: test_oid zero >actual && t0000-basic.sh: test_oid zero >actual && These are all in test cases checking that 'test_oid' actually works, and that the size of its output matches the size of the corresponding hash function with conditions like test $(wc -c expect && t1500-rev-parse.sh: echo "$(test_oid algo)" >expect && t4044-diff-index-unique-abbrev.sh: echo "$(test_oid val1)" > foo && t4044-diff-index-unique-abbrev.sh: echo "$(test_oid val2)" > foo && t5313-pack-bounds-checks.sh: echo $(test_oid oidfff) >file && And there is yet another similar case in an in-flight topic at: https://public-inbox.org/git/813e81a058227bd373cec802e443fcd677042fb4.1670862677.git.gitgitgadget@gmail.com/ Arguably we would be better off if 'test_oid' terminated its output with a LF. So let's update 'test_oid' accordingly, update its tests in t0000 to account for the extra character in those size tests, and remove the now unnecessary 'echo $(...)' command substitutions around 'test_oid' invocations as well.

test-lib: add a --invert-exit-code switch

2022-07-27T23:35:40Z

Add the ability to have those tests that fail return 0, and those tests that succeed return 1. This is useful e.g. to run "--stress" tests on tests that fail 99% of the time on some setup, i.e. to smoke out the flaky run which yielded success. In a subsequent commit a new SANITIZE=leak mode will make use of this. Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano

test-lib: have --immediate emit valid TAP on failure

2022-03-24T21:47:02Z

Change the "--immediate" option so that it emits valid TAP on failure. Before this it would omit the required plan at the end, e.g. under SANITIZE=leak we'd show a "No plan found in TAP output" error from "prove": $ prove t0006-date.sh :: --immediate t0006-date.sh .. Dubious, test returned 1 (wstat 256, 0x100) Failed 1/22 subtests Test Summary Report ------------------- t0006-date.sh (Wstat: 256 Tests: 22 Failed: 1) Failed test: 22 Non-zero exit status: 1 Parse errors: No plan found in TAP output Files=1, Tests=22, 0 wallclock secs ( 0.02 usr 0.01 sys + 0.18 cusr 0.06 csys = 0.27 CPU) Result: FAIL Now we'll emit output that doesn't result in TAP parsing failures: $ prove t0006-date.sh :: --immediate t0006-date.sh ..

t0001-t0028: avoid pipes with Git on LHS

2022-03-13T00:22:01Z

Pipes ignore error codes of LHS command and thus we should not use them with Git in tests. As an alternative, use a 'tmp' file to write the Git output so we can test the exit code. Signed-off-by: Shubham Mishra Signed-off-by: Junio C Hamano

test-lib tests: get rid of copy/pasted mock test code

2021-09-22T23:22:41Z

Now that we've split up the write_sub_test_lib_test*() and run_sub_test_lib_test*() functions let's fix those tests in t0000-basic.sh that were verbosely copy/pasting earlier tests. That we caught all of them was asserted with a follow-up change that's not part of this series[1], we might add such a duplication check at some later time, but for now let's just one-off remove the duplicate boilerplate. 1. https://lore.kernel.org/git/patch-v3-6.9-bc79b29f3c-20210805T103237Z-avarab@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano

test-lib tests: don't provide a description for the sub-tests

2021-09-22T23:22:41Z

Change the $test_description provided for the generated subtests to be constant, since the only purpose of having it is that test-lib.sh will barf if it isn't supplied. The other purpose of having it was to effectively split up the test description between the argument to test_expect_success and the argument to "write_and_run_sub_test_lib_test". Let's only use one of the two. Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano

test-lib tests: split up "write and run" into two functions

2021-09-22T23:22:41Z

Refactor the function to write and run tests of the test-lib.sh output into two functions. When this was added back in 565b6fa87bb (tests: refactor mechanics of testing in a sub test-lib, 2012-12-16) there was no reason to do this, but since we started supporting test arguments in 517cd55fd51 (test-lib: self-test that --verbose works, 2013-06-23) we've started to write out duplicate tests simply to test different arguments, now we'll be able to re-use them. This change doesn't consolidate any of those tests yet, it just makes it possible to do so. All the changes in t0000-basic.sh are a simple search-replacement. Since the _run_sub_test_lib_test_common() function doesn't handle running the test anymore we can do away with the sub-shell, which was used to scope an "unset" and "export" shell variables.

t0000: avoid masking git exit value through pipes

2021-09-16T20:43:42Z

9af0b8dbe2 (t0000-basic: more commit-tree tests., 2006-04-26) adds tests for commit-tree that mask the return exit from git as described in a378fee5b07 (Documentation: add shell guidelines, 2018-10-05). Fix the tests, to avoid pipes by using a temporary file instead. Signed-off-by: Carlo Marcelo Arenas Belón Signed-off-by: Junio C Hamano
