Mon May 10 09:48:00 PDT 2010
Git uses a simple and yet powerful test framework, written in shell.
The framework is easy to use for both users and developers so I think
it would help if it is used in notmuch as well.
This is a copy of Git's test framework from commit
b6b0afdc30e066788592ca07c9a6c6936c68cc11 in git repository.

+Core GIT Tests
+==============
+
+This directory holds many test scripts for core GIT tools. The
+first part of this short document describes how to run the tests
+and read their output.
+
+When fixing the tools or adding enhancements, you are strongly
+encouraged to add tests in this directory to cover what you are
+trying to fix or enhance. The later part of this short document
+describes how your test scripts should be organized.
+
+
+Running Tests
+-------------
+
+The easiest way to run tests is to say "make". This runs all
+the tests.
+
+ *** t0000-basic.sh ***
+ * ok 1: .git/objects should be empty after git-init in an empty repo.
+ * ok 2: .git/objects should have 256 subdirectories.
+ * ok 3: git-update-index without --add should fail adding.
+ ...
+ * ok 23: no diff after checkout and git-update-index --refresh.
+ * passed all 23 test(s)
+ *** t0100-environment-names.sh ***
+ * ok 1: using old names should issue warnings.
+ * ok 2: using old names but having new names should not issue warnings.
+ ...
+
+Or you can run each test individually from command line, like
+this:
+
+ $ sh ./t3001-ls-files-killed.sh
+ * ok 1: git-update-index --add to add various paths.
+ * ok 2: git-ls-files -k to show killed files.
+ * ok 3: validate git-ls-files -k output.
+ * passed all 3 test(s)
+
+You can pass --verbose (or -v), --debug (or -d), and --immediate
+(or -i) command line argument to the test, or by setting GIT_TEST_OPTS
+appropriately before running "make".
+
+--verbose::
+ This makes the test more verbose. Specifically, the
+ command being run and their output if any are also
+ output.
+
+--debug::
+ This may help the person who is developing a new test.
+ It causes the command defined with test_debug to run.
+
+--immediate::
+ This causes the test to immediately exit upon the first
+ failed test.
+
+--long-tests::
+ This causes additional long-running tests to be run (where
+ available), for more exhaustive testing.
+
+--valgrind::
+ Execute all Git binaries with valgrind and exit with status
+ 126 on errors (just like regular tests, this will only stop
+ the test script when running under -i). Valgrind errors
+ go to stderr, so you might want to pass the -v option, too.
+
+ Since it makes no sense to run the tests with --valgrind and
+ not see any output, this option implies --verbose. For
+ convenience, it also implies --tee.
+
+--tee::
+ In addition to printing the test output to the terminal,
+ write it to files named 't/test-results/$TEST_NAME.out'.
+ As the names depend on the tests' file names, it is safe to
+ run the tests with this option in parallel.
+
+--with-dashes::
+ By default tests are run without dashed forms of
+ commands (like git-commit) in the PATH (it only uses
+ wrappers from ../bin-wrappers). Use this option to include
+ the build directory (..) in the PATH, which contains all
+ the dashed forms of commands. This option is currently
+ implied by other options like --valgrind and
+ GIT_TEST_INSTALLED.
+
+You can also set the GIT_TEST_INSTALLED environment variable to
+the bindir of an existing git installation to test that installation.
+You still need to have built this git sandbox, from which various
+test-* support programs, templates, and perl libraries are used.
+If your installed git is incomplete, it will silently test parts of
+your built version instead.
+
+When using GIT_TEST_INSTALLED, you can also set GIT_TEST_EXEC_PATH to
+override the location of the dashed-form subcommands (what
+GIT_EXEC_PATH would be used for during normal operation).
+GIT_TEST_EXEC_PATH defaults to `$GIT_TEST_INSTALLED/git --exec-path`.
+
+
+Skipping Tests
+--------------
+
+In some environments, certain tests have no way of succeeding
+due to platform limitation, such as lack of 'unzip' program, or
+filesystem that do not allow arbitrary sequence of non-NUL bytes
+as pathnames.
+
+You should be able to say something like
+
+ $ GIT_SKIP_TESTS=t9200.8 sh ./t9200-git-cvsexport-commit.sh
+
+and even:
+
+ $ GIT_SKIP_TESTS='t[0-4]??? t91?? t9200.8' make
+
+to omit such tests. The value of the environment variable is a
+SP separated list of patterns that tells which tests to skip,
+and either can match the "t[0-9]{4}" part to skip the whole
+test, or t[0-9]{4} followed by ".$number" to say which
+particular test to skip.
+
+Note that some tests in the existing test suite rely on previous
+test item, so you cannot arbitrarily disable one and expect the
+remainder of test to check what the test originally was intended
+to check.
+
+
+Naming Tests
+------------
+
+The test files are named as:
+
+ tNNNN-commandname-details.sh
+
+where N is a decimal digit.
+
+First digit tells the family:
+
+ 0 - the absolute basics and global stuff
+ 1 - the basic commands concerning database
+ 2 - the basic commands concerning the working tree
+ 3 - the other basic commands (e.g. ls-files)
+ 4 - the diff commands
+ 5 - the pull and exporting commands
+ 6 - the revision tree commands (even e.g. merge-base)
+ 7 - the porcelainish commands concerning the working tree
+ 8 - the porcelainish commands concerning forensics
+ 9 - the git tools
+
+Second digit tells the particular command we are testing.
+
+Third digit (optionally) tells the particular switch or group of switches
+we are testing.
+
+If you create files under t/ directory (i.e. here) that is not
+the top-level test script, never name the file to match the above
+pattern. The Makefile here considers all such files as the
+top-level test script and tries to run all of them. A care is
+especially needed if you are creating a common test library
+file, similar to test-lib.sh, because such a library file may
+not be suitable for standalone execution.
+
+
+Writing Tests
+-------------
+
+The test script is written as a shell script. It should start
+with the standard "#!/bin/sh" with copyright notices, and an
+assignment to variable 'test_description', like this:
+
+ #!/bin/sh
+ #
+ # Copyright (c) 2005 Junio C Hamano
+ #
+
+ test_description='xxx test (option --frotz)
+
+ This test registers the following structure in the cache
+ and tries to run git-ls-files with option --frotz.'
+
+
+Source 'test-lib.sh'
+--------------------
+
+After assigning test_description, the test script should source
+test-lib.sh like this:
+
+ . ./test-lib.sh
+
+This test harness library does the following things:
+
+ - If the script is invoked with command line argument --help
+ (or -h), it shows the test_description and exits.
+
+ - Creates an empty test directory with an empty .git/objects
+ database and chdir(2) into it. This directory is 't/trash directory'
+ if you must know, but I do not think you care.
+
+ - Defines standard test helper functions for your scripts to
+ use. These functions are designed to make all scripts behave
+ consistently when command line arguments --verbose (or -v),
+ --debug (or -d), and --immediate (or -i) is given.
+
+
+End with test_done
+------------------
+
+Your script will be a sequence of tests, using helper functions
+from the test harness library. At the end of the script, call
+'test_done'.
+
+
+Test harness library
+--------------------
+
+There are a handful helper functions defined in the test harness
+library for your script to use.
+
+ - test_expect_success <message> <script>
+
+ This takes two strings as parameter, and evaluates the
+ <script>. If it yields success, test is considered
+ successful. <message> should state what it is testing.
+
+ Example:
+
+ test_expect_success \
+ 'git-write-tree should be able to write an empty tree.' \
+ 'tree=$(git-write-tree)'
+
+ - test_expect_failure <message> <script>
+
+ This is NOT the opposite of test_expect_success, but is used
+ to mark a test that demonstrates a known breakage. Unlike
+ the usual test_expect_success tests, which say "ok" on
+ success and "FAIL" on failure, this will say "FIXED" on
+ success and "still broken" on failure. Failures from these
+ tests won't cause -i (immediate) to stop.
+
+ - test_debug <script>
+
+ This takes a single argument, <script>, and evaluates it only
+ when the test script is started with --debug command line
+ argument. This is primarily meant for use during the
+ development of a new test script.
+
+ - test_done
+
+ Your test script must have test_done at the end. Its purpose
+ is to summarize successes and failures in the test script and
+ exit with an appropriate error code.
+
+ - test_tick
+
+ Make commit and tag names consistent by setting the author and
+ committer times to defined stated. Subsequent calls will
+ advance the times by a fixed amount.
+
+ - test_commit <message> [<filename> [<contents>]]
+
+ Creates a commit with the given message, committing the given
+ file with the given contents (default for both is to reuse the
+ message string), and adds a tag (again reusing the message
+ string as name). Calls test_tick to make the SHA-1s
+ reproducible.
+
+ - test_merge <message> <commit-or-tag>
+
+ Merges the given rev using the given message. Like test_commit,
+ creates a tag and calls test_tick before committing.
+
+Tips for Writing Tests
+----------------------
+
+As with any programming projects, existing programs are the best
+source of the information. However, do _not_ emulate
+t0000-basic.sh when writing your tests. The test is special in
+that it tries to validate the very core of GIT. For example, it
+knows that there will be 256 subdirectories under .git/objects/,
+and it knows that the object ID of an empty tree is a certain
+40-byte string. This is deliberately done so in t0000-basic.sh
+because the things the very basic core test tries to achieve is
+to serve as a basis for people who are changing the GIT internal
+drastically. For these people, after making certain changes,
+not seeing failures from the basic test _is_ a failure. And
+such drastic changes to the core GIT that even changes these
+otherwise supposedly stable object IDs should be accompanied by
+an update to t0000-basic.sh.
+
+However, other tests that simply rely on basic parts of the core
+GIT working properly should not have that level of intimate
+knowledge of the core GIT internals. If all the test scripts
+hardcoded the object IDs like t0000-basic.sh does, that defeats
+the purpose of t0000-basic.sh, which is to isolate that level of
+validation in one place. Your test also ends up needing
+updating when such a change to the internal happens, so do _not_
+do it and leave the low level of validation to t0000-basic.sh.
