this feature by setting the GIT_TEST_CHAIN_LINT environment
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
+ 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
+ about the failure. Note that the verbose output of each test
+ job is saved to 't/test-results/$TEST_NAME.stress-<nr>.out',
+ and only the output of the failed test job is shown on the
+ terminal. The names of the trash directories get a
+ '.stress-<nr>' suffix, and the trash directory of the failed
+ test job is renamed to end with a '.stress-failed' suffix.

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_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
+prerequisite when adding more strings for translation. See "Testing
+marked strings" in po/README for details.
+
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_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-config(1).
+
GIT_TEST_INDEX_THREADS=<n> enables exercising the multi-threaded loading
of the index for the whole test suite by bypassing the default number of
cache entries and thread minimums. Setting this to 1 will make the
index loading single threaded.
+GIT_TEST_MULTI_PACK_INDEX=<boolean>, when true, forces the multi-pack-
+index to be written after every 'git repack' command, and overrides the
+'core.multiPackIndex' setting to true.

Naming Tests
------------
- Creates an empty test directory with an empty .git/objects database
and chdir(2) into it. This directory is 't/trash
directory.$test_name_without_dotsh', with t/ subject to change by
- the --root option documented above.
+ the --root option documented above, and a '.stress-<N>' suffix
+ appended by the --stress option.
- Defines standard test helper functions for your scripts to
use. These functions are designed to make all scripts behave
