From: Junio C Hamano Date: Sat, 7 Apr 2007 14:17:35 +0000 (-0700) Subject: t3030: merge-recursive backend test. X-Git-Tag: v1.5.2-rc0~39^2 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=885b98107547fe3f6d17ca0af0578e040f7600d0;p=git.git t3030: merge-recursive backend test. We have fairly extensive coverage of read-tree 3-way machinery, and many Porcelain-ish tests use git-merge front-end tests, but we did not have good basic test for merge-recursive, which made it very hard to hack on it. I used this during the recent work to teach D/F conflicts to merge-recursive.
