Do not redirect test_emacs stderr to /dev/null. Test_emacs uses
emacsclient(1) now and it does not print unwanted messages (like
those from `message') to stderr. But it does print useful
errors, e.g. when emacs server connection fails, given expression
is not valid or undefined function is called.
Set SCREENRC and SYSSCREENRC environment variables to "/dev/null"
as suggested by Jim Paris to avoid potential problems with
screen(1) configuration files.
Before the change, emacs run in daemon mode without any visible
buffers. Turns out that this affects emacs behavior in some
cases. In particular, `window-end' function returns `point-max'
instead of the last visible position. That makes it hard or
impossible to implement some tests. The patch runs emacs in a
detached screen(1) session. So that it works exactly as if it
has a visible window.
Note: screen terminates when emacs exits. So the patch does not
introduce new "running processes left behind" issues.
- explain test_expect_equal_file
- remove mention of test_expect_failure, since that function was removed.

This means that test_subtest_known_broken needs to be called before
every known broken subtest, which is no different than what is
documented for the test_begin_subtest case.
The assumption is that every test ends up calling either skipping,
calling test_ok_ or test_failure_ and and the latter in turn delegate
to the known_broken versions in the case where
test_subtest_known_broken_ is set.
There is existing support for broken tests. But it is not convenient
to use. The primary issue is that we have to maintain a set of
test_expect_*_failure functions which are equivalent to the normal
test_expect_* counterparts except for what functions are called for
result reporting. The patch adds test_subtest_known_broken function
which marks a subset as broken, making the normal test_expect_*
functions behave as test_expect_*_failure. All test_expect_*_failure
functions are removed. Test_known_broken_failure_ is changed to
format details the same way as test_failure_ does.
Another benefit of this change is that the diff when a broken test is
fixed would be small and nice.
Documentation is updated accordingly.
Before the change, every Emacs test ran in a separate Emacs
instance. Starting Emacs many times wastes considerable time and
it gets worse as the test suite grows. The patch solves this by
using a single Emacs server and emacsclient(1) to run multiple
tests. Emacs server is started on the first test_emacs call and
stopped when test_done is called. We take care not to leave
orphan Emacs processes behind when test is terminated by whatever
reason: Emacs server runs a watchdog that periodically checks
that the test is still running.
Some tests need to provide user input. Before the change, this
was done using echo(1) to Emacs stdin. This no longer works and
instead `standard-input' variable is set accordingly to make
`read' return the appropriate string.
Without this, mail messages delivered by emacs_deliver_message might
not be seen by the next invocation of "notmuch new", (which can lead
to test-suite failures if emacs_deliver_message is fast enough).
Change add_email_corpus, emacs_deliver_message and tests to use
$TEST_DIRECTORY instead of '..'.
This improves the behavior of the usage of --root=<dir>, as the
assumption of what '..' means will usually be incorrect.
Document -root option in README and update valgrind to work with
-root.
Instead of generating auxiliary run_emacs script every time
test_emacs is run, do it once in the beginning of the test.
Also, use absolute paths in the script to make it more robust.
Using `setq' for setting variables in Emacs tests affect other
tests that may run in the same Emacs environment. Currently it
works because each test is run in a separate Emacs instance. But
in the future multiple tests will run in a single Emacs instance.
The patch changes all variables to use `let', so the scope of the
change is limited to a single test.
Most test_emacs calls have long arguments that consist of many
expressions. Putting them on a single line makes it hard to read
and produces poor diff when they are changed. The patch puts
every expression in test_emacs calls on a separate line.

In the master branch in test/emacs two tests access the build users home
directory, so does emacs_deliver_message in the crypto branch.
The tests should not touch the build user's home directory. The patch
creates a directory in the temporary test directory and sets home
accordingly.
In case of a non-existent home directory, the tests are failing without
this patch.

Before the change, test_expect_equal_file moved files it compared
in case of failure. The patch changes it to copy the files
instead. This allows testing non-temporary files which are
stored in git.
Note: the change should not result in new temporary files left
after the tests. Test_expect_equal_file used to move files only
on failure, so callers had to cleanup them anyway.
This adds a new "crypto" test script to the test suite to test
PGP/MIME signature verification and message decryption. Included here
is a test GNUPGHOME with a test secret key (passwordless), and test
for:
* signing/verification
* signing/verification with full owner trust
* verification with signer key unavailable
* encryption/decryption
* decryption failure with missing key
* encryption/decryption + signing/verfifying
* reply to encrypted message
* verification of signature from revoked key
These tests are not expected to pass now, but will as crypto
functionality is included.
We need to be able to test for the presence of a newline at the end of
output. There's no good way to capture trailing newlines in bash, so
redirecting output to a file is the next best thing. This new
function should be used when testing for output that is expected to
have trailing newlines.
The next commit will demonstrate the use of this.
Change #!/bin/bash at start of tests to "#!/usr/bin/env bash". That way
systems running on bash < 4 can prepend bash >= 4 to path before
running the tests.
The patch adds test-lib.el file for Emacs tests auxiliary stuff.
Currently, it implements two functions: `visible-buffer-string'
and `visible-buffer-substring'. These are similar to standard
counterparts without "visible-" prefix but exclude invisible
text. The functions are not used anywhere at the moment but
should be useful for testing hiding/showing in the Emacs
interface.
Edited-by: Carl Worth <cworth@cworth.org> Fixed "basic" test to ignore
new test-lib.el file.
Previously, this directory was only preserved for failing tests. But
it's important to be able to easily debug known-broken tests, so
preserve the actual vs. expected output for those as well.
When test_begin_subtest is not followed by corresponding test_expect_equal,
the output of the rest of the test script is errornously suppressed. Add
code to detect these bugs in test scripts.
The newline was removed from say_color in commit 222926ab to allow
printing test status in the beginning of the line. Error messages are
never followed by other text so we add the newline to error function.
Git-style tests (test_expect_success etc.) suppress stdout and stderr
unless -v is given. Notmuch-style tests (created by test_begin_subtest
and test_expect_equal) do not have this behavior so implement it the
same.
Additionally, for both test styles, the test-lib.sh is changed so that
the content of suppressed stdout and stderr is shown in case of failed
test.
Finally a test for this functionality is added to basic tests.
We have test names like maildir-sync now, so it's cleaner if the
temporary files created are named things like maildir-sync-10.out
rather than maildir-10.out. Presumably the extra stripping here came
from naming conventions in git's test suite.
This was too rude of a thing to do and could easily introduce
problems, (as reported by Rob Browning whose environment required some
HOME-specific things for shell startup).
Instead, implement more focused changes to ensure that particular file
in $HOME don't cause problems. Specifically, we fix known problems
with ~/.signature and ~/.mailrc here.
After any emacs test failure, the tmp.emacs directory will have this
run_emacs script in it which the user can use to run emacs within the
test suite environment, (pointing at the test suite's notmuch
database, using the local notmuch command-line program, and the local
notmuch emacs lisp code).
The bash code in the test suite is using associative arrays which were
only added to bash as of release 4.0.
If the test suite is run with an older bash, we now immediately error
out and explain the situation, (instead of emitting confusing error
messages and failing dozens of tests, which is what happened before
this change).
We set the HOME environment variable to the test directory to avoid
the tests relying on any configuration files from the test author's
own home directory, (such as ${HOME}/.emacs or similar).
We simulate the act of selecting the "inbox" saved search from
notmuch-hello and the act of selecting a desired thread from the
notmuch-search results.
The test for the navigation of notmuch-hello is currently marked as
BROKEN since its output is in the opposite order compared to the
'(notmuch-search "tag:inbox")' test. This question of ordering is a
currently open issue on the notmuch mailing list, so we'll let the
test suite reflect that for now.
Finally, this commit also abstracts some common emacs lisp code,
(waiting for the current buffer's process to complete), into a new
notmuch-test-wait function that is made available to anything calling
test_emacs.
This should be quite handy for doing automated testing of the
emacs-based functionality in notmuch. This function invokes emacs with
the necessary command-line arguments, (to run in batch mode with no
local initialization, to load the notmuch code from the source
directory, and to ensure an 80-column width).
When the NOTMUCH variable was originally invented it was used as an
explicit path to the notmuch binary being tested. Today, the test
suite sets the PATH variable instead, so the NOTMUCH variable always
has a value of simply "notmuch".
We simplifying that by using the constant value rather than the
continual variable reference.
Now that we can usefully pass section names via the NOTMUCH_SKIP_TESTS
environment variable, it's useful to actually print those names out
for the user. Then, since we're now printing these names, let's use
nicer names, (not excessively long but also not using abbreviations
like "msg").
In order for --valgrind to be useful, we drop noisy additional output of
all of the commands being executed in verbose mode. This makes --verbose
alone quite useless, so we don't document it any more.
Also, add a zlib valgrind suppression that was showing up frequently in the
test suite.
By scanning test-lib.sh for occurrences of "git" or "GIT", I found
that most of those are internal things, (like the GIT_TEST_TEE_STARTED
variable). But GIT_SKIP_TESTS is part of the user-interface to the
test suite, so we rename it to reference notmuch rather than git.
Also, the GIT_TRACE warning is git-specific, so we drop that as well.
The original git test suite works by concatenating many commands into
a very long string (each separated by &&). This is painful to work
with since it prevents the editor from helping by parsing the shell
script, indenting, colorizing, etc.
Instead, we switch this back to something like the original notmuch
test suite, and add two new functions to test-lib.sh
(test_begin_subtest and test_expect_equal) to support these.
This also fixes the test suite to once again display the diff when a
test fails to generate the expected input.
This makes the new, git-derived test suite report results in a manner
similar to the original notmuch test suite.
Notable changes include:
* No more initial '*' on every line
* Only colorize a single word
* Don't print useless test numbers
* Use "PASS" in place of "ok"
* Begin sentences with a capital letter
* Print test descriptions for each block
* Separate each block of tests with a blank line
* Don't summarize counts between each block
In order to have repeatable test suite, all times in messages are set
to UTC time zone to match the time zone (TZ variable) set in
test-lib.sh.

Modify the helper functions to work with git-based test suite i.e.
1) Quote arguments where it is necessary.
2) Do not use $NOTMUCH. It is equal to "notmuch" since $PATH is set to
the build tree.
3) Modify pass_if_equal to fit into the git-based test suite.

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
