    consistently when command line arguments --verbose (or -v),
    --debug (or -d), and --immediate (or -i) is given.
 
+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

+ - test_set_prereq SOME_PREREQ
+
+   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

+
+	if ! test_have_prereq PERL

+   test_external_has_tap variable somewhere before calling the first
+   test_external* function. See t9700-perl-git.sh for an example.
+
+	# The external test will outputs its own plan
+	test_external_has_tap=1
+
+ - test_external_without_stderr [<prereq>] <message> <external> <script>
+
+   Like test_external but fail if there's any output on stderr,
+   instead of checking the exit code.
+
+	test_external_without_stderr \
+	    'Perl API' \
+	    "$PERL_PATH" "$TEST_DIRECTORY"/t9700/test.pl
+
+ - 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
+   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" &&

 Subject: [PATCH] a patch
 
+From nobody Mon Sep 17 00:00:00 2001
+From: Junio Hamano <junkio@cox.net>
+Date: Thu, 20 Aug 2009 17:18:22 -0700
+Subject: Why doesn't git-am does not like >8 scissors mark?
+
+Subject: [PATCH] BLAH ONE
+
+In real life, we will see a discussion that inspired this patch
+discussing related and unrelated things around >8 scissors mark
+in this part of the message.
+
+Subject: [PATCH] BLAH TWO
+
+And then we will see the scissors.
+
+ This line is not a scissors mark -- >8 -- but talks about it.
+ - - >8 - - please remove everything above this line - - >8 - -
+
+Subject: [PATCH] Teach mailinfo to ignore everything before -- >8 -- mark
+From: Junio C Hamano <gitster@pobox.com>
+
+This teaches mailinfo the scissors -- >8 -- mark; the command ignores
+everything before it in the message body.
+
+Signed-off-by: Junio C Hamano <gitster@pobox.com>

+This repository is for testing the ability to group revisions
+correctly along tags and branches.  Here is its history:
+
+  1.  The initial import (revision 1.1 of everybody) created a
+      directory structure with a file named `default' in each dir:
+
+            ./
+              default
+              sub1/default
+                   subsubA/default
+                   subsubB/default
+              sub2/default
+                   subsubA/default
+              sub3/default
+
+  2.  Then tagged everyone with T_ALL_INITIAL_FILES.
+
+  3.  Then tagged everyone except sub1/subsubB/default with
+      T_ALL_INITIAL_FILES_BUT_ONE.
+
+  4.  Then created branch B_FROM_INITIALS on everyone.
+
+  5.  Then created branch B_FROM_INITIALS_BUT_ONE on everyone except
+      /sub1/subsubB/default.
+
+  6.  Then committed modifications to two files: sub3/default, and
+      sub1/subsubA/default.
+
+  7.  Then committed a modification to all 7 files.
+
+  8.  Then backdated sub3/default to revision 1.2, and
+      sub2/subsubA/default to revision 1.1, and tagged with T_MIXED.
+
+  9.  Same as 8, but tagged with -b to create branch B_MIXED.
+
+  10. Switched the working copy to B_MIXED, and added
+      sub2/branch_B_MIXED_only.  (That's why the RCS file is in
+      sub2/Attic/ -- it never existed on trunk.)
+
+  11. In one commit, modified default, sub1/default, and
+      sub2/subsubA/default, on branch B_MIXED.
+
+  12. Did "cvs up -A" on sub2/default, then in one commit, made a
+      change to sub2/default and sub2/branch_B_MIXED_only.  So this
+      commit should be spread between the branch and the trunk.
+
+  13. Do "cvs up -A" to get everyone back to trunk, then make a new
+      branch B_SPLIT on everyone except sub1/subsubB/default,v.
+
+  14. Switch to branch B_SPLIT (see sub1/subsubB/default disappear)
+      and commit a change that affects everyone except sub3/default.
+
+  15. An hour or so later, "cvs up -A" to get sub1/subsubB/default
+      back, then commit a change on that file, on trunk.  (It's
+      important that this change happened after the previous commits
+      on B_SPLIT.)
+
+  16. Branch sub1/subsubB/default to B_SPLIT, then "cvs up -r B_SPLIT"
+      to switch the whole working copy to the branch.
+
+  17. Commit a change on B_SPLIT, to sub1/subsubB/default and
+      sub3/default.
