We do it implicitly, in the test cases that use the helpers. However, t/test-lib.sh does not particularly verify that the test helpers have been built. And I think that is a good thing: we do have several test scripts, I would think, that do not require any test helper to begin with. These scripts can work pretty well without having to build anything (read: on a machine where there is not even a toolchain available to build things). Besides, it is pretty much only t/helper/test-tool these days, and it is unlikely that anybody has a `test-tool` in their `PATH`. If they do, they'll find out soon enough iff they test with `GIT_TEST_INSTALLED` and iff they do not have the test helper(s) in t/helper/ ;-) Ciao, Dscho > I do not offhand see how tests would work in a pristine checkout with > "cd t && sh t0000-*.sh" as t/test-lib.sh is not running $(MAKE) itself > (and the design of the test-lib.sh, as can be seen in the check this > part of it makes, is to just abort if we cannot test) with this patch > (and PATCH 1/5) under the test-installed mode, though. > > > Signed-off-by: Johannes Schindelin <johannes.schinde...@gmx.de> > > --- > > t/test-lib.sh | 2 +- > > 1 file changed, 1 insertion(+), 1 deletion(-) > > > > diff --git a/t/test-lib.sh b/t/test-lib.sh > > index 832ede5099..1ea20dc2dc 100644 > > --- a/t/test-lib.sh > > +++ b/t/test-lib.sh > > @@ -51,7 +51,7 @@ export LSAN_OPTIONS > > > > ################################################################ > > # It appears that people try to run tests without building... > > -"$GIT_BUILD_DIR/git" >/dev/null > > +test -n "$GIT_TEST_INSTALLED" || "$GIT_BUILD_DIR/git" >/dev/null || > > if test $? != 1 > > then > > echo >&2 'error: you do not seem to have built git yet.' >
