implied by other options like --valgrind and
GIT_TEST_INSTALLED.
+--no-bin-wrappers::
+ By default, the test suite uses the wrappers in
+ `../bin-wrappers/` to execute `git` and friends. With this option,
+ `../git` and friends are run directly. This is not recommended
+ in general, as the wrappers contain safeguards to ensure that no
+ files from an installed Git are used, but can speed up test runs
+ especially on platforms where running shell scripts is expensive
+ (most notably, Windows).
+
--root=<directory>::
Create "trash" directories used to store all temporary data during
testing under <directory>, instead of the t/ directory.
variable to "1" or "0", respectively.
--stress::
---stress=<N>::
Run the test script repeatedly in multiple parallel jobs until
one of them fails. Useful for reproducing rare failures in
flaky tests. The number of parallel jobs is, in order of
- precedence: <N>, or the value of the GIT_TEST_STRESS_LOAD
+ precedence: the value of the GIT_TEST_STRESS_LOAD
environment variable, or twice the number of available
processors (as shown by the 'getconf' utility), or 8.
Implies `--verbose -x --immediate` to get the most information
'.stress-<nr>' suffix, and the trash directory of the failed
test job is renamed to end with a '.stress-failed' suffix.
+--stress-jobs=<N>::
+ Override the number of parallel jobs. Implies `--stress`.
+
+--stress-limit=<N>::
+ When combined with --stress run the test script repeatedly
+ this many times in each of the parallel jobs or until one of
+ them fails, whichever comes first. Implies `--stress`.

You can also set the GIT_TEST_INSTALLED environment variable to
the bindir of an existing git installation to test that installation.
You still need to have built this git sandbox, from which various
could be enabled by running the test suite with correct GIT_TEST_
environment set.
+GIT_TEST_FAIL_PREREQS<non-empty?> fails all prerequisites. This is
+useful for discovering issues with the tests where say a later test
+implicitly depends on an optional earlier test.
+
+There's a "FAIL_PREREQS" prerequisite that can be used to test for
+whether this mode is active, and e.g. skip some tests that are hard to
+refactor to deal with it. The "SYMLINKS" prerequisite is currently
+excluded as so much relies on it, but this might change in the future.
+
GIT_TEST_GETTEXT_POISON=<non-empty?> turns all strings marked for
translation into gibberish if non-empty (think "test -n"). Used for
spotting those tests that need to be marked with a C_LOCALE_OUTPUT
GIT_TEST_SPLIT_INDEX=<boolean> forces split-index mode on the whole
test suite. Accept any boolean values that are accepted by git-config.
+GIT_TEST_PROTOCOL_VERSION=<n>, when set, overrides the
+'protocol.version' setting to n if it is less than n.
+
GIT_TEST_FULL_IN_PACK_ARRAY=<boolean> exercises the uncommon
pack-objects code path where there are more than 1024 packs even if
the actual number of packs in repository is below this limit. Accept
for the index version specified. Can be set to any valid version
(currently 2, 3, or 4).
+GIT_TEST_PACK_SPARSE=<boolean> if enabled will default the pack-objects
+builtin to use the sparse object walk. This can still be overridden by
+the --no-sparse command-line argument.
+
GIT_TEST_PRELOAD_INDEX=<boolean> exercises the preload-index code path
by overriding the minimum number of cache entries required per thread.
-GIT_TEST_REBASE_USE_BUILTIN=<boolean>, when false, disables the
-builtin version of git-rebase. See 'rebase.useBuiltin' in
+GIT_TEST_STASH_USE_BUILTIN=<boolean>, when false, disables the
+built-in version of git-stash. See 'stash.useBuiltin' in
git-config(1).
GIT_TEST_INDEX_THREADS=<n> enables exercising the multi-threaded loading
fetch-pack to not request sideband-all (even if the server advertises
sideband-all).
+GIT_TEST_DISALLOW_ABBREVIATED_OPTIONS=<boolean>, when true (which is
+the default when running tests), errors out when an abbreviated option
+is used.

Naming Tests

...
'
+ - test_atexit <script>
+
+ Prepend <script> to a list of commands to run unconditionally to
+ clean up before the test script exits, e.g. to stop a daemon:
+
+ test_expect_success 'test git daemon' '
+ git daemon &
+ daemon_pid=$! &&
+ test_atexit 'kill $daemon_pid' &&
+ hello world
+ '
+
+ The commands will be executed before the trash directory is removed,
+ i.e. the atexit commands will still be able to access any pidfiles or
+ socket files.
+
+ Note that these commands will be run even when a test script run
+ with '--immediate' fails. Be careful with your atexit commands to
+ minimize any changes to the failed state.
+
- test_write_lines <lines>
Write <lines> on standard output, one line per argument.
test_oid_init or test_oid_cache. Providing an unknown key is an
error.
+ - yes [<string>]
+
+ This is often seen in modern UNIX but some platforms lack it, so
+ the test harness overrides the platform implementation with a
+ more limited one. Use this only when feeding a handful lines of
+ output to the downstream---unlike the real version, it generates
+ only up to 99 lines.
