2021-03-18fsmonitor: add perf test for git diff HEADNipunn Koorapati
Update the xargs call so that if your large repo contains symlinks, test-tool chmtime failure does not end the script.

2018-04-25Merge branch 'ps/test-chmtime-get'Junio C Hamano
Test cleanup. * ps/test-chmtime-get: t/helper: 'test-chmtime (--get|-g)' to print only the mtime
2018-04-09t/helper: 'test-chmtime (--get|-g)' to print only the mtimePaul-Sebastian Ungureanu
Compared to 'test-chmtime -v +0 file' which prints the mtime and and the file name, 'test-chmtime --get file' displays only the mtime. If it is used in combination with (+|=|=+|=-|-)seconds, it changes and prints the new value. test-chmtime -v +0 file | sed 's/[^0-9].*$//' is now equivalent to: test-chmtime --get file Signed-off-by: Paul-Sebastian Ungureanu <ungureanupaulsebastian@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-04-15test helpers: move test-* to t/helper/ subdirectoryNguyễn Thái Ngọc Duy
This keeps top dir a bit less crowded. And because these programs are for testing purposes, it makes sense that they stay somewhere in t/ Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
