+
+--valgrind::
+ Execute all Git binaries with valgrind and exit with status
+ 126 on errors (just like regular tests, this will only stop
+ the test script when running under -i). Valgrind errors
+ go to stderr, so you might want to pass the -v option, too.
+
+ Since it makes no sense to run the tests with --valgrind and
+ not see any output, this option implies --verbose. For
+ convenience, it also implies --tee.

+--tee::
+ In addition to printing the test output to the terminal,
+ write it to files named 't/test-results/$TEST_NAME.out'.
+ As the names depend on the tests' file names, it is safe to
+ run the tests with this option in parallel.
+
+--with-dashes::
+ By default tests are run without dashed forms of
+ commands (like git-commit) in the PATH (it only uses
+ wrappers from ../bin-wrappers). Use this option to include
+ the build directory (..) in the PATH, which contains all
+ the dashed forms of commands. This option is currently
+ implied by other options like --valgrind and
+ GIT_TEST_INSTALLED.
+
+You can also set the GIT_TEST_INSTALLED environment variable to
+the bindir of an existing git installation to test that installation.
+You still need to have built this git sandbox, from which various
+test-* support programs, templates, and perl libraries are used.
+If your installed git is incomplete, it will silently test parts of
+your built version instead.
+
+When using GIT_TEST_INSTALLED, you can also set GIT_TEST_EXEC_PATH to
+override the location of the dashed-form subcommands (what
+GIT_EXEC_PATH would be used for during normal operation).
+GIT_TEST_EXEC_PATH defaults to `$GIT_TEST_INSTALLED/git --exec-path`.
+
+
+Skipping Tests
+--------------
+
+In some environments, certain tests have no way of succeeding
+due to platform limitation, such as lack of 'unzip' program, or
+filesystem that do not allow arbitrary sequence of non-NUL bytes
+as pathnames.
+
+You should be able to say something like
+
+ $ GIT_SKIP_TESTS=t9200.8 sh ./t9200-git-cvsexport-commit.sh
+
+and even:
+
+ $ GIT_SKIP_TESTS='t[0-4]??? t91?? t9200.8' make
+
+to omit such tests. The value of the environment variable is a
+SP separated list of patterns that tells which tests to skip,
+and either can match the "t[0-9]{4}" part to skip the whole
+test, or t[0-9]{4} followed by ".$number" to say which
+particular test to skip.
+
+Note that some tests in the existing test suite rely on previous
+test item, so you cannot arbitrarily disable one and expect the
+remainder of test to check what the test originally was intended
+to check.
