From 5502039d87337e076e69f7de949cb0e0360de16f Mon Sep 17 00:00:00 2001 From: Johan Herland Date: Fri, 29 Apr 2011 11:36:16 +0200 Subject: [PATCH] Add several testcases for --dirstat and friends Currently, t4013 is the only selftest that exercises the --dirstat machinery, but it only does a superficial verification of --dirstat's output. This patch adds a new selftest - t4047-diff-dirstat.sh - which prepares a commit containing: - unchanged files, changed files and files with rearranged lines - copied files, moved files, and unmoved files It then verifies the correct dirstat output for that commit in the following dirstat modes: - --dirstat - -X - --dirstat=0 - -X0 - --cumulative - --dirstat-by-file - (plus combinations of the above) Each of the above tests are also run with: - no rename detection - rename detection (-M) - expensive copy detection (-C -C) Improved-by: Junio C Hamano Signed-off-by: Johan Herland
