+Some tests require external dependencies to run. Without them, they
+will be skipped, or (rarely) marked failed. Please install these, so

Running Tests
-------------
The easiest way to run tests is to say "make test", (or simply run the

one of the executable scripts in this directory, (such as ./search,
-./reply, etc.)
+./reply, etc). Note that you will probably want "make test-binaries"
+before running individual tests.
The following command-line options are available when running tests:
As the names depend on the tests' file names, it is safe to
run the tests with this option in parallel.
+--root=<dir>::
+ This runs the testsuites specified under a seperate directory.
+ However, caution is advised, as not all tests are maintained
+ with this relocation in mind, so some tests may behave
+ differently.
+
+ Pointing this argument at a tmpfs filesystem can improve the
+ speed of the test suite for some users.
+
When invoking the test suite via "make test" any of the above options
can be specified as follows:
make test OPTIONS="--verbose"
+You can choose an emacs binary to run the tests in one of the
+following ways.
+
+ TEST_EMACS=my-special-emacs make test
+ TEST_EMACS=my-special-emacs ./emacs
+ make test TEST_EMACS=my-special-emacs

Skipping Tests

If, for any reason, you need to skip one or more tests, you can do so

<script>. If it yields success, test is considered
successful. <message> should state what it is testing.
- 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_begin_subtest <message>
Set the test description message for a subsequent test_expect_equal
invocation (see below).
+ test_subtest_known_broken
+
+ Mark the current test as broken. Such tests are expected to fail.
+ Unlike the normal tests, which say "PASS" on success and "FAIL" on
+ failure, these will say "FIXED" on success and "BROKEN" on failure.
+ Failures from these tests won't cause -i (immediate) to stop. A
+ test must call this before any test_expect_* function.
+
test_expect_equal <output> <expected>
This is an often-used convenience function built on top of
will generate a failure and print the difference of the two
strings.
- test_expect_equal_failure <output> <expected>
+ test_expect_equal_file <output> <expected>
- This works similar to test_expect_equal (see above) but is used to
- mark a test that demonstrates a known breakage, (that is, the
- author of the test expectes "output" and "expected" to differ until
- the breakage is fixed). See test_expect_failure for details.
+ Identical to test_exepect_equal, except that <output> and
+ <expected> are files instead of strings. This is a much more
+ robust method to compare formatted textual information, since it
+ also notices whitespace and closing newline differences.
test_debug <script>
This function executes the provided emacs lisp script within
emacs. The script can be a sequence of emacs lisp expressions,
- (that is, they will be evaluated within a progn form). The lisp
- expressions can call `message' to generate output on stdout to be
- examined by the calling test script.
+ (that is, they will be evaluated within a progn form). Emacs
+ stdout and stderr is not available, the common way to get output
+ is to save it to a file. There are some auxiliary functions
+ useful in emacs tests provided in test-lib.el. Do not use `setq'
+ for setting variables in Emacs tests because it affects other
+ tests that may run in the same Emacs instance. Use `let' instead
+ so the scope of the changed variables is limited to a single test.
+
+ test_emacs_expect_t <emacs-lisp-expressions>
+
+ This function executes the provided emacs lisp script within
+ emacs in a manner similar to 'test_emacs'. The expressions should
+ return the value `t' to indicate that the test has passed. If the
+ test does not return `t' then it is considered failed and all data
+ returned by the test is reported to the tester.
test_done
is to summarize successes and failures in the test script and
exit with an appropriate error code.
