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_PRELOAD_INDEX=<boolean> exercises the preload-index code path
by overriding the minimum number of cache entries required per thread.
+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
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
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.
