Add a --long-tests option to test-lib.sh, which enables tests to selectively run more exhaustive (longer running, potentially brute-force) tests. Such exhaustive tests would only be useful if one works on the specific module that is being tested -- for a general "cd t/; make" to check whether everything is OK, such exhaustive tests shouldn't be run by default since the longer it takes to run the tests, the less often they are actually run.
Signed-off-by: Lea Wiemann <LeWiemann@gmail.com> --- Right now I'm using this in the Mechanize test for exhaustive link checking on each page. I've caught bugs with this (such as the "[PATCH] gitweb: fix support for repository directories with spaces" that I just sent), so it's actually useful for development, but it's so slow that I wouldn't want it to be run unless the user requests it -- the link checking is really quite brute-force and doesn't cover much more than the actual test. Actual breakages (regressions) are quite likely to be caught by the normal test.
Running the Mechanize test in long mode takes more than 1 minute on my system, vs 5 seconds in normal mode -- and that's just with a really short draft of the test suite. So running those long tests unconditionally would slow down "cd t; make" unncessarily, and we want tests to be fast so that people actually run them.
Is the wording OK? --long-tests and GIT_TEST_LONG were the best terms I could come up with off the top of my head.
(ISTR that there's some large open source project that uses this strategy (long vs. normal tests) quite extensively, but I can't recall which one; hints appreciated. GCC uses it in its compatibility tests; its testsuite/README.compat reads,
Normally, only a small amount of compatibility tests is run. Setting RUN_ALL_COMPAT_TESTS=1 in the environment before running the testsuite enables running all compatibility tests, but might take significantly longer than it takes without this variable.)
