From 82ebb0b6ec7470cab96a013d3d719c109003ef83 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 12 Mar 2008 17:36:36 -0400 Subject: add test_cmp function for test scripts Many scripts compare actual and expected output using "diff -u". This is nicer than "cmp" because the output shows how the two differ. However, not all versions of diff understand -u, leading to unnecessary test failure. This adds a test_cmp function to the test scripts and switches all "diff -u" invocations to use it. The function uses the contents of "$GIT_TEST_CMP" to compare its arguments; the default is "diff -u". On systems with a less-capable diff, you can do: GIT_TEST_CMP=cmp make test Signed-off-by: Jeff King Signed-off-by: Junio C Hamano --- t/t4027-diff-submodule.sh | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 't/t4027-diff-submodule.sh') diff --git a/t/t4027-diff-submodule.sh b/t/t4027-diff-submodule.sh index 3d2d0816a3..1fd3fb74d7 100755 --- a/t/t4027-diff-submodule.sh +++ b/t/t4027-diff-submodule.sh @@ -37,17 +37,17 @@ test_expect_success setup ' test_expect_success 'git diff --raw HEAD' ' git diff --raw --abbrev=40 HEAD >actual && - diff -u expect actual + test_cmp expect actual ' test_expect_success 'git diff-index --raw HEAD' ' git diff-index --raw HEAD >actual.index && - diff -u expect actual.index + test_cmp expect actual.index ' test_expect_success 'git diff-files --raw' ' git diff-files --raw >actual.files && - diff -u expect actual.files + test_cmp expect actual.files ' test_done -- cgit v1.3-6-g1900
