+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-db in an empty repo.
+ * ok 2: .git/objects should have 256 subdirectories.
+ * ok 3: git-update-cache without --add should fail adding.
+ ...
+ * ok 23: no diff after checkout and git-update-cache --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-cache --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.
+
+--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.
+
+
+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)
+
+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'
+ 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 the opposite of test_expect_success. If <script>
+ yields success, test is considered a failure.
+
+ Example:
+
+ test_expect_failure \
+ 'git-update-cache without --add should fail adding.' \
+ 'git-update-cache should-be-empty'
+
+ - 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.
+
+
+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.

+
+This test runs very basic features, like registering things in cache,

+test_description='Three way merge with read-tree -m
+
+This test tries three-way merge with read-tree -m
+
+There is one ancestor (called O for Original) and two branches A
+and B derived from it. We want to do a 3-way merge between A and
+B, using O as the common ancestor.
+
+ merge A O B
+
+Decisions are made by comparing contents of O, A and B pathname
+by pathname. The result is determined by the following guiding
+principle:
+
+ - If only A does something to it and B does not touch it, take
+ whatever A does.
+
+ - If only B does something to it and A does not touch it, take
+ whatever B does.
+
+ - If both A and B does something but in the same way, take
+ whatever they do.
+
+ - If A and B does something but different things, we need a
+ 3-way merge:
+
+ - We cannot do anything about the following cases:
+
+ * O does not have it. A and B both must be adding to the
+ same path independently.
+
+ * A deletes it. B must be modifying.
+
+ - Otherwise, A and B are modifying. Run 3-way merge.
+
+First, the case matrix.
+
+ - Vertical axis is for A'\''s actions.
+ - Horizontal axis is for B'\''s actions.

+test_description='Two way merge with read-tree -m $H $M
+
+This test tries two-way merge (aka fast forward with carry forward).
+
+There is the head (called H) and another commit (called M), which is
+simply ahead of H. The index and the work tree contains a state that
+is derived from H, but may also have local changes. This test checks
+all the combinations described in the two-tree merge "carry forward"
+rules, found in <Documentation/git-rev-tree.txt>.
+
+In the test, these paths are used:
+ bozbar - in H, stays in M, modified from bozbar to gnusto
+ frotz - not in H added in M
+ nitfol - in H, stays in M unmodified
+ rezrov - in H, deleted in M
+ yomin - not in H nor M

+test_description='Two way merge with read-tree --emu23 $H $M
+
+This test tries two-way merge (aka fast forward with carry forward).
+
+There is the head (called H) and another commit (called M), which is
+simply ahead of H. The index and the work tree contains a state that
+is derived from H, but may also have local changes. This test checks
+all the combinations described in the two-tree merge "carry forward"
+rules, found in <Documentation/git-rev-tree.txt>.
+
+In the test, these paths are used:
+ bozbar - in H, stays in M, modified from bozbar to gnusto
+ frotz - not in H added in M
+ nitfol - in H, stays in M unmodified
+ rezrov - in H, deleted in M
+ yomin - not in H nor M

+ NAME
+ ----
+-git-ls-tree - Displays a tree object in human readable form
++git-ls-tree - Lists the contents of a tree object.
+
+
+ SYNOPSIS
+ --------
+-'git-ls-tree' [-r] [-z] <tree-ish> [paths...]
++'git-ls-tree' [-d] [-r] [-z] <tree-ish> [paths...]
+
+ DESCRIPTION
+ -----------
+-Converts the tree object to a human readable (and script processable)
+-form.
++Lists the contents of a tree object, like what "/bin/ls -a" does
++in the current working directory.
+
+ OPTIONS
+ -------
+ <tree-ish>::
+ Id of a tree.
+
++-d::
++ show only the named tree entry itself, not its children
++
+ -r::
+ recurse into sub-trees
+
+@@ -28,18 +31,19 @@ OPTIONS
+ \0 line termination on output
+
+ paths::
+- Optionally, restrict the output of git-ls-tree to specific
+- paths. Directories will only list their tree blob ids.
+- Implies -r.
++ When paths are given, shows them. Otherwise implicitly
++ uses the root level of the tree as the sole path argument.
++
+
+ Output Format
+ -------------
+- <mode>\t <type>\t <object>\t <file>
++ <mode> SP <type> SP <object> TAB <file>

+-git-ls-tree - Displays a tree object in human readable form

+ SYNOPSIS
+ --------
+-'git-ls-tree' [-r] [-z] <tree-ish> [paths...]
++'git-ls-tree' [-d] [-r] [-z] <tree-ish> [paths...]
+
+ DESCRIPTION
+ -----------
+-Converts the tree object to a human readable (and script processable)
+-form.
++Lists the contents of a tree object, like what "/bin/ls -a" does
++in the current working directory.
+
+ OPTIONS
+ -------
+ <tree-ish>::
+ Id of a tree.
+
++-d::
++ show only the named tree entry itself, not its children
++
+ -r::
+ recurse into sub-trees
+
+@@ -28,18 +31,19 @@ OPTIONS
+ \0 line termination on output
+
+ paths::
+- Optionally, restrict the output of git-ls-tree to specific
+- paths. Directories will only list their tree blob ids.
+- Implies -r.
++ When paths are given, shows them. Otherwise implicitly
++ uses the root level of the tree as the sole path argument.
++
+
+ Output Format
+ -------------
+- <mode>\t <type>\t <object>\t <file>
++ <mode> SP <type> SP <object> TAB <file>

+test_description='git-tar-tree and git-get-tar-commit-id test
+
+This test covers the topics of file contents, commit date handling and
+commit id embedding:
+
+ The contents of the repository is compared to the extracted tar
+ archive. The repository contains simple text files, symlinks and a
+ binary file (/bin/sh). Only pathes shorter than 99 characters are
+ used.
+
+ git-tar-tree applies the commit date to every file in the archive it
+ creates. The test sets the commit date to a specific value and checks
+ if the tar archive contains that value.
+
+ When giving git-tar-tree a commit id (in contrast to a tree id) it
+ embeds this commit id into the tar archive as a comment. The test
+ checks the ability of git-get-tar-commit-id to figure it out from the
+ tar file.
