+--no-bin-wrappers::
+ By default, the test suite uses the wrappers in

+ 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

--root=<directory>::
Create "trash" directories used to store all temporary data during
testing under <directory>, instead of the t/ directory.
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.
