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 <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

test_description='git add -u
|
|
|
|
This test creates a working tree state with three files:
|
|
|
|
top (previously committed, modified)
|
|
dir/sub (previously committed, modified)
|
|
dir/other (untracked)
|
|
|
|
and issues a git add -u with path limiting on "dir" to add
|
|
only the updates to dir/sub.
|
|
|
|
Also tested are "git add -u" without limiting, and "git add -u"
|
|
without contents changes.'
