From fc688759b95e6888bb1dc4c4d00d27dca4e59ddb Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Sat, 24 Jul 2010 06:16:35 -0500 Subject: [PATCH] t1501 (rev-parse): clarify MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Tweak the style of these tests to make them easier to read. - Replace test_rev_parse() which produced multiple mini-tests with a simple function that can be used with the test body. - Combine multiple mini-tests into larger chunks that are easier to read. - Do not hard-code object IDs. We may use a different hash some day. - Use test_cmp in preference to the test builtin. The former produces useful output when tests are run with the "-v" option. - Guard all test code with test_expect_success. This makes it much easier to visually scan through the test and find code of interest. - Use subshells to make the current directory easier to track. Outside of any subshell, the current directory is always $TEST_DIRECTORY now. Also add a new test demonstrating a possible bug noticed in the process of cleaning up: “git rev-parse --show-prefix” leaves out the trailing newline after an empty prefix when cwd is at the toplevel of the work tree.
