Since the tests all output TAP (see http://testanything.org) they can
-be run with any TAP harness. Here's an example of paralell testing
+be run with any TAP harness. Here's an example of parallel testing
powered by a recent version of prove(1):
$ prove --timer --jobs 15 ./t[0-9]*.sh
- 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.
+ - Creates an empty test directory with an empty .git/objects database
+ and chdir(2) into it. This directory is 't/trash
+ directory.$test_name_without_dotsh', with t/ subject to change by
+ the --root option documented above.
- Defines standard test helper functions for your scripts to
use. These functions are designed to make all scripts behave
There are a handful helper functions defined in the test harness
library for your script to use.
- - test_expect_success <message> <script>
+ - test_expect_success [<prereq>] <message> <script>
- This takes two strings as parameter, and evaluates the
+ Usually takes two strings as parameter, and evaluates the
<script>. If it yields success, test is considered
successful. <message> should state what it is testing.
'git-write-tree should be able to write an empty tree.' \
'tree=$(git-write-tree)'
- - test_expect_failure <message> <script>
+ If you supply three parameters the first will be taken to be a
+ prerequisite, see the test_set_prereq and test_have_prereq
+ documentation below:
+
+ test_expect_success TTY 'git --paginate rev-list uses a pager' \
+ ' ... '
+
+ - test_expect_failure [<prereq>] <message> <script>
This is NOT the opposite of test_expect_success, but is used
to mark a test that demonstrates a known breakage. Unlike
success and "still broken" on failure. Failures from these
tests won't cause -i (immediate) to stop.
+ Like test_expect_success this function can optionally use a three
+ argument invocation with a prerequisite as the first argument.
+
+ - test_expect_code [<prereq>] <code> <message> <script>
+
+ Analogous to test_expect_success, but pass the test if it exits
+ with a given exit <code>
+
+ test_expect_code 1 'Merge with d/f conflicts' 'git merge "merge msg" B master'
+
- test_debug <script>
This takes a single argument, <script>, and evaluates it only
Merges the given rev using the given message. Like test_commit,
creates a tag and calls test_tick before committing.
+ - 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
+ test-lib.sh for more). Others you can set yourself and use later
+ with either test_have_prereq directly, or the three argument
+ invocation of test_expect_success and test_expect_failure.
+
+ - test_have_prereq SOME PREREQ
+
+ Check if we have a prerequisite previously set with
+ test_set_prereq. The most common use of this directly is to skip
+ all the tests if we don't have some essential prerequisite:
+
+ if ! test_have_prereq PERL
+ then
+ skip_all='skipping perl interface tests, perl not available'
+ test_done
+ fi
+
+ - test_external [<prereq>] <message> <external> <script>
+
+ Execute a <script> with an <external> interpreter (like perl). This
+ was added for tests like t9700-perl-git.sh which do most of their
+ work in an external test script.
+
+ test_external \
+ 'GitwebCache::*FileCache*' \
+ "$PERL_PATH" "$TEST_DIRECTORY"/t9503/test_cache_interface.pl
+
+ If the test is outputting its own TAP you should set the
+ 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
