Subject: [PATCH 02/24] t7600 (merge): modernize style
Date: Tue, 17 Aug 2010 01:53:56 -0500 [thread overview]
Message-ID: <20100817065356.GB22057@burratino> (raw)
In-Reply-To: <20100817065147.GA18293@burratino>
Guard setup commands with test_expect_success, so they are easier
to visually skip over and get to the good part. While at it:
- use "printf '%s\n' a b ..." instead of "cat <<EOF" for test
vectors with short lines;
- use test_cmp instead of test foo = bar where possible, for
better output with -v on failure;
- do not go to extraordinary lengths to print a relevant message
when test commands fail. There is a patch in flight that could be
used to restore the nice error messages in a cleaner way.
