+Do's, don'ts & things to keep in mind
+-------------------------------------
+
+Here are a few examples of things you probably should and shouldn't do
+when writing tests.
+
+Do:
+
+ - Put all code inside test_expect_success and other assertions.
+
+   Even code that isn't a test per se, but merely some setup code
+   should be inside a test assertion.
+
+ - Chain your test assertions
+
+   Write test code like this:
+
+	git merge foo &&
+	git push bar &&
+	test ...
+
+   Instead of:
+
+	git merge hla
+	git push gh
+	test ...
+
+   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:
+
+	export HLAGH;
+	git merge hla &&
+	git push gh &&
+	test ...
+
+Don't:
+
+ - exit() within a <script> part.
+
+   The harness will catch this as a programming error of the test.
+   Use test_done instead if you need to stop the tests early (see
+   "Skipping tests" below).
+
+ - Break the TAP output
+
+   The raw output from your test may be interpreted by a TAP harness. TAP
+   harnesses will ignore everything they don't know about, but don't step
+   on their toes in these areas:
+
+   - Don't print lines like "$x..$y" where $x and $y are integers.
+
+   - Don't print lines that begin with "ok" or "not ok".
+
+   TAP harnesses expect a line that begins with either "ok" and "not
+   ok" to signal a test passed or failed (and our harness already
+   produces such lines), so your script shouldn't emit such lines to
+   their output.
+
+   You can glean some further possible issues from the TAP grammar
+   (see http://search.cpan.org/perldoc?TAP::Parser::Grammar#TAP_Grammar)
+   but the best indication is to just run the tests with prove(1),
+   it'll complain if anything is amiss.
+
+Keep in mind:
+
+ - Inside <script> part, the standard output and standard error
+   streams are discarded, and the test harness only reports "ok" or
+   "not ok" to the end user running the tests. Under --verbose, they
+   are shown to help debugging the tests.
+
+
+Skipping tests
+--------------
+
+If you need to skip all the remaining tests you should set skip_all
+and immediately call test_done. The string you give to skip_all will
+be used as an explanation for why the test was skipped. for instance:
+
+	if ! test_have_prereq PERL
+	then
+	    skip_all='skipping perl interface tests, perl not available'
+	    test_done
+	fi
 
 End with test_done

+   Set a test prerequisite to be used later with test_have_prereq. The
+   test-lib will set some prerequisites for you, e.g. PERL and PYTHON
+   which are derived from ./GIT-BUILD-OPTIONS (grep test_set_prereq

+
+ - test_must_fail <git-command>
+
+   Run a git command and ensure it fails in a controlled way.  Use
+   this instead of "! <git-command>" to fail when git commands
+   segfault.
+
+ - 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

+ - 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
