We can also start with something small that does not contend to replace the entire test suite, and evolve from there as we have time. Your initial patch looks very good, I will give it a cursory review (only cursory because we are technically in a feature-freeze...) > diff --git a/Makefile b/Makefile > index 2a81ae22e9..567387b558 100644 > --- a/Makefile > +++ b/Makefile > @@ -644,6 +644,7 @@ X = > > PROGRAMS += $(patsubst %.o,git-%$X,$(PROGRAM_OBJS)) > > +TEST_PROGRAMS_NEED_X += test-3071-wildmatch I guess I can always work on unifying those gazillion of test executables into a single one later. For testing purposes, I have to bundle them (BusyBox-based MinGit is supposed to be stand-alone, yet I want to test it to verify that it works even if it ships only a subset of Git for Windows), and they dominate the payload of any prerelease, as you can see e.g. here: https://github.com/git-for-windows/git/releases/tag/v2.16.0-rc1.windows.1 > diff --git a/t/helper/test-3071-wildmatch.c b/t/helper/test-3071-wildmatch.c > new file mode 100644 > index 0000000000..24a657202d > --- /dev/null > +++ b/t/helper/test-3071-wildmatch.c > @@ -0,0 +1,273 @@ > +#include "cache.h" > +#include "test-lib.h" > + > +struct match_input { > + int expect_true; > + const char *text; > + const char *pattern; > +}; > + > +static struct match_input match_tests[] = { > + /* Basic wildmatch features */ > + { 1, "foo", "foo" }, > + { 0, "foo", "bar" }, > + { 1, "", "" }, These patterns share the "magic-ness" of Ævar's test cases... although your version is certainly more concise. BTW IIRC Ævar explicitly said that he needs to use `ls-files` in order to test the interaction with the index, so that would probably take a little bit more work. > diff --git a/t/t3071-wildmatch.sh b/t/t3071-wildmatch.sh > new file mode 100755 > index 0000000000..6e83b4d684 > --- /dev/null > +++ b/t/t3071-wildmatch.sh > @@ -0,0 +1,3 @@ > +#!/bin/sh > + > +exec helper/test-3071-wildmatch t3071-wildmatch "$@" Should it not be `exec test-3071-wildmatch "${0%.sh}" "$@"`? > diff --git a/test-lib.c b/test-lib.c > new file mode 100644 > index 0000000000..8e8b7cd6df > --- /dev/null > +++ b/test-lib.c > @@ -0,0 +1,97 @@ > [...] Lots of good stuff in there. Definitely a good start. Ciao, Dscho
