That way all of the commands in your tests will succeed or fail. If
- you must ignore the return value of something (e.g. the return
- value of export is unportable) it's best to indicate so explicitly
- with a semicolon:
+ you must ignore the return value of something (e.g., the return

+ best to indicate so explicitly with a semicolon:
- export HLAGH;

+ - test_must_fail <git-command>
+
+ Run a git command and ensure it fails in a controlled way. Use
+ this instead of "! <git-command>". When git-command dies due to a
+ segfault, test_must_fail diagnoses it as an error; "! <git-command>"
+ treats it as just another expected failure, which would let such a
+ bug go unnoticed.
+
+ - test_might_fail <git-command>
+
+ Similar to test_must_fail, but tolerate success, too. Use this
+ instead of "<git-command> || :" to catch failures due to segv.
+
+ - test_cmp <expected> <actual>
+
+ Check whether the content of the <actual> file matches the
+ <expected> file. This behaves like "cmp" but produces more
+ helpful output when the test is run with "-v" option.
+
+ - test_when_finished <script>
+
+ Prepend <script> to a list of commands to run to clean up
+ at the end of the current test. If some clean-up command
+ fails, the test will not pass.
+
+ Example:
+
+ test_expect_success 'branch pointing to non-commit' '
+ git rev-parse HEAD^{tree} >.git/refs/heads/invalid &&
+ test_when_finished "git update-ref -d refs/heads/invalid" &&
+ ...
+ '
