* add functionality for filtering mail log by ID
This was not planned, but as @polarthene mentioned in
https://github.com/docker-mailserver/docker-mailserver/pull/3033#issuecomment-1407169569
, filtering the mail log by email ID would be (the only) correct
approach for the Rspamd test (to eliminate race conditions).
I asserted the currect state, and came to the conclusion that this might
(or actually is) something we want in more than one place. So I went
ahead and implemented a solution.
The solution for acquiring the ID is a bit slower because it ensures the
mail queue is empty _before_ and _after_ the mail is sent. This is the
tradeoff one has to make if they want to send multiple emails in one
test file and get their IDs.
I hope you like this approach. I will provide another PR that adjusts
our current tests to use these new functions.
* added note about our helper functions in the docs
I think our work for our custom test framework should be noted in the
docs for newcomers to better understand what they should do.
* adjust Rspamd test to use new helpers for sending
* improve filter helpers further
* add sanity check when acquiring mail ID
* re-add `refute_output` to test which should now work well
This doesn't make any difference to the tests performed here (_partly due to `--preference`_).
It would make a difference if performing a test for receiving a grade, which would otherwise fail due to chain of trust not being verifiable for a self-signed certificate (_or a signed certificate without a CA public key to verify against_)
* chore: Use a common method to check domain and fqdn config
* chore: Shift other test cases into shared test methods
* chore: Add another shared method for checking mail headers
* chore: Add another shared method for checking hostname
* refactor: Improve quality of shared test methods
Based on changes from an earlier closed hostname PR from Oct 2021 with additional revision to use `assert_output` and more thorough checking of values expected in output.
* chore: Move clean shutdown test to `process-check-restart.bats`
This was originally a single test case in `tests.bats` intended for `supervisord` testing.
It seems at some point it got reassigned to a hostname override test container, and then migrated to separate test file for hostname override test by accident.
It now belongs in the correct place again, as hostname config should have nothing to do with a graceful shutdown?
* chore: Prepare for migrating to use `test/helper/setup.bash`
* chore: Rename containers and configured FQDN settings
* chore: Convert to using common container setup helpers
Wait for SMTP port is left at the end to avoid additional start-up delays.
* chore: Use `_run_in_container_bash` helper
* chore: Be more specific on matching mail headers
- I could do multiple container grep calls instead, but opted to match by lines in file. This better ensures values are being matched to the correct lines.
- Renamed the test case descriptions.
- Expanded test coverage of the 4th container as it represents another DNS config, while the 3rd is just the 4th container with the `SRS_DOMAINNAME` env added, no value in more coverage there.
* chore: Remove redundant test coverage in `tests.bats`
These checks are performed in `mail_hostname.bats` with better coverage.
* chore: Move each containers setup into it's own test-case instead
* chore: Re-arrange container name IDs
The original `fqdn-with-subdomain` is now `with-nis-domain` which is more accurate. A new test case will properly cover the default `--hostname` only config that is not a bare domain.
* chore: Re-arrange test cases to align with new ID ordering
This commit just shifts the test cases, no new changes to any content beyond that.
* chore: Add new test case for default config
* chore: Review feedback `_run_in_container_bash` to `_run_in_container`
Co-authored-by: Georg Lauterbach <44545919+georglauterbach@users.noreply.github.com>
* chore: Additional review feedback
- Fix a suggested change bug with quote wrapping an interpolated variable.
- Convert two other `_bash` methods that were missed from review.
- Apply the last two suggested changes from review.
* chore: `_exec_in_container_bash` to `_exec_in_container`
The `| head -n 1` can be dropped if we know for sure it's only one line, which is what we expect. Quotes can then be dropped too.

* tests(fix): `spam_junk_folder.bats` Wait on Amavis port to be ready
Postfix can potentially be ready before Amavis is. This caused test failures as mail was sent before Amavis was ready to process it.
Both test cases shared the same test logic, except for the expected location to deliver the spam to. Extracted into a shared test method, and moved the port conditions into there.
* tests(chore): `spam_junk_folder.bats` minor revisions
Test case descriptions, container names and test prefix are now more descriptive of what is under test here (an ENV for Amavis).
* tests(chore): Move Amavis bounce test into `spam_junk_folder.bats`
These two tests seem to be related to the same feature. Grouping them into a single test file instead.
* tests(refactor): Split shared method into smaller methods
Now it can be better shared with the bounce test case.
* tests(chore): Shift test cases to match their CONTAINER_NAME order
No changes to code, just cut + paste of the `CONTAINER3_NAME` test case to shift it to the last test case position.
* added options to toggle OpenDKIM & OpenDMARC
rspamd can provide DKIM signing and DMARC checking itself, so users
should be able to disable OpenDKIM & OpenDMARC. The default is left at
1, so users have to to opt-in when the want to disable the features.
* misc small enhancements
* adjusted start of rspamd
The order of starting redis + rspamd was reversed (now correct) and
rspamd now starts with the correct user.
* adjusted rspamd core configuration
The main configuration was revised. This includes AV configuration as
well as worker/proxy/controller configuration used to control the main
rspamd processes.
The configuration is not tested extensively, but well enough that I am
confident to go forward with it until we declare rspamd support as
stable.
* update & improve the documentation
* add tests
These are some initial tests which test the most basic functionality.
* tests(refactor): Improve consistency and documentation for test helpers (#3012)
* added `ALWAYS_RUN` target `Makefile` recipies (#3013)
This ensures the recipies are always run.

* chore: Co-locate process checking and process restart verification
Extract the test cases for checking a process is running and properly restarts from various test files into a single one:
Core (always running):
opendkim, opendmarc, master (postfix)
ENV dependent:
amavi (amavisd-new), clamd, dovecot, fail2ban-server (fail2ban), fetchmail, postgrey, postsrsd, saslauthd
These now run off a single container with the required ENV and call a common function (the revised version in parallel test cases).
* fix(saslauthd): Quote wrap supervisor config vars
`saslauth.conf` calls `-O` option for most commands defined with an ENV that may be empty/null. This would cause the process to silently fail / die.
This doesn't happen if quote wrapping the ENV, which calls `-O` with an empty string.
Not necessary, but since one of `postgrey` ENV were quote wrapped in `supervisor-app.conf`, I've also done the same there.
* fix(postsrsd): Change supervisor `autorestart` policy to `true`
The PR that introduced the config switched from `true` to `unexpected` without any context. That prevents restart working when the process is killed. Setting to `true` instead will correctly restart the service.
* chore: Remove disabled postgrey test file
`mail_with_postgrey_disabled_by_default.bats` only checked the migrated test cases, removed as no longer serving a purpose.
* tests(refactor): Make `_should_restart_when_killed()` more reliable
The previous version did not ensure that the last checks process was actually restarted, only that it was running.
It turns out that `pkill` is only sending the signal, there can be some delay before the original process is actually killed and restarted.
This can be identified with `pgrep --older <seconds>`. First ensure the process is at a specified age, then after killing check that the process is not running that is at least that old, finally check that there is a younger process actually running.. (_could fail if a process doesn't restart, or there is a delay such as imposed by `sleep` in wrapper scripts for postfix and fail2ban_)
The helper method is not used anywhere else now, move it into this test instead. It has been refactored to accomodate the needs for `--older`, and `--list-full` provides some output that can be matched (similar for `pkill --echo`).
* test(docs): Add inline notes about processes
* chore: Compress test cases into single case with loop
Moves the list of processes into array vars to iterate through instead.
If a failure occurs, the process name is visible along with line number in `_should_restart_when_killed()` to identify what went wrong.
* chore: Handle `FETCHMAIL_PARALLEL=1` process checks as well
* tests: Add test case for disabled ENV
Additional coverage to match what other test files were doing before, ensuring that these ENV can prevent their respective service from running.
* chore: Move `clamd` enabled check to it's own test case
Not sure about this.
It reduces the time of CPU activity (sustained full load on a thread) and increase in memory usage (1GB+ loading signatures database), but as a separate test case it also adds 10 seconds without reducing the time of the test case it was extracted from.
* chore: Make `disabled` variant the 1st test case
* fix: Adjust test cases to pass when using slower wrapper scripts
* tests(refactor): `mail_fetchmail.bats` updated to new format
Additionally merges in the parallel test file.
* chore: Move `config/fetchmail.cf` into separate sub-directory
Keep out of the default base config for tests.
* chore: Change `fetchmail.cf` FQDNs to `.test` TLD
Changed the first configs remote and local user values to more clearly document what their values should represent (_and that they don't need to be a full mail address, that's just what our Dovecot is configured with for login_).
Shifted the `here` to the end of the `is` line. It's optional syntax, only intended to contrast with the remote `there` for readability.
Additionally configured imap protocol. Not tested or verified if that's correct configuration for usage with imap protocol instead. The fetchmail feature tests are currently lacking.
Added an inline doc into the fetchmail test to reference a PR about the importance of the trailing `.` in the config. Updated the partial matching to ensure it matches for that in the value as well.
* chore: Finalize `process-check-restart.bats`
Few minor adjustments. The other ENV for clamd doesn't seem to provide any benefit, trim out the noise. Added a note about why it's been split out.
Fetchmail parallel configs are matching the config file path in the process command that is returned. The `.rc` suffix is just to add further clarity to that.
* tests(refactor): `mail_changedetector.bats` - Leverage DRY methods
`supervisorctl tail` is not the most reliably way to get logs for the latest change detection and has been known to be fragile in the past.
We can instead read the full log for the service directly with `tac` and `sed` to extract all log content since the last change detection.
Common asserts have also been extracted out into separate methods.
* tests(chore): Remove sleep and redundant change event
Container 1 is still blocked at this point from an existing lock and change event.
Make the lock stale immediately and no extra sleep is required when paired with the helper method to wait until the event is processed (which should remove the stale lock).
* tests(refactor): Add more DRY methods
- Simplify the test case so it's easier to grok.
- 2nd test case (blocking) extracts out initial setup into a separate method and merges the later service restart logic which is redundant.
- Additional comments for improved context of what is going on / expected.
* tests(chore): Revise the change detection helper method
- Add explicit counting arg to change detection support.
- Extract revised logic into it's own generic helper method.
- Utilize this for a separate method that monitors for a change event having started, but not waiting for completion.
This allows dropping the 40 sec of remaining `sleep` in `mail_changedetector` test. It was also required due to potentially missing the timing of a change event completing concurrently in a 2nd container that needed to be waited on and then checked.
* tests(chore): Migrate to current test conventions
- Switch to common container setup helpers
- Update container name and change usage to variables instead.
- Adopt the new convention of prefix variable for test cases (revised test case descriptions).
* tests(chore): Remove legacy change detection
This has since been replaced with the new helper watches the `changedetector` service logs directly instead of only detecting a change has occurred via checksum comparison.
No tests use this method anymore, it was originally for `tests.bats`. Thus the tests in `test_helper.bats` are being dropped too. The new helper has test coverage in `changedetector` tests.
* chore: Lock removal should not incur `sleep 5` afterwards
- A new lock should be created by this script after removal. The sleep doesn't help avoid a race condition with lock file creation after removal.
- Reduces test time as a bonus.
- Added some additional comments to test.
* tests(chore): `tls_letsencrypt.bats` leverage improved change detection
- No need to wait on the change detection service anymore during container startup.
- No need to count change events processed either as waiting a fixed duration is no longer relied on.
- This makes the reload count method redundant, dropped.
* tests(chore): Convert `setup-cli.bats` to new test conventions
This test file was already adapted to the original common setup helpers.
- `TEST_NAME` replaced with `CONTAINER_NAME`.
- Prefix var added, test case descriptions drop explicit prefix.
- No other changes.
* tests(chore): Extract out helpers related to change-detection
- New helper file for sharing these helpers to tests.
- Includes the helpful log method from changedetector tests.
- No longer need to maintain duplicate copies of these methods during the test migration. All tests that use them are now importing the separate helper file.
- `tls_letsencrypt.bats` has switched to using the log helper.
- Generic log count helper is removed from `test_helper/common.bash` as any test that needs it in future can adapt to `helper/common.bash`.
* tests(refactor): `tls_letsencrypt.bats` remove `_get_service_logs()`
This helper does not seem useful as moving away from `supervisorctl tail` and no other tests had a need for it.
* tests(chore): Remove common setup methods from `test_helper/common.bash`
No other tests depend on this. Future tests will adopt the revised versions from `helper/setup.bash`.
Additionally updates `helper/setup.bash` comments that are no longer applicable to `TEST_TMP_CONFIG` and `CONTAINER_NAME`.
* chore: Use `|| true` to simplify setting `EXPECTED_COUNT` correctly
* chore: Drop ENV `ENABLE_POSTFIX_VIRTUAL_TRANSPORT`
* tests(chore): Remove redundant `dovecot-lmtp` config
None of this is needed. Only relevant change is changing the LMTP service listener for Dovecot and that can be delegated to `user-patches.sh`.
* tests(refactor): Use `user-patches.sh` instead of replacing config file
The only relevant changes in `test/config/dovecot-lmtp` regarding LMTP was:
- `/etc/dovecot/dovecot.conf` (`protocols = imap lmtp`) and `/etc/dovecot/protocols.d/` (`protocols = $protocols lmtp`).
- `conf.d/10-master.conf` only changed the LMTP service listener from a unix socket to TCP on port 24 (_this was the only change required for the test to pass_).
None of those configs are required as:
- `protocols = imap pop3 lmtp` [is the upstream default](https://doc.dovecot.org/settings/core/#core_setting-protocols), no need to add `lmtp`.
- The LMTP service listener is now configured for the test with `user-patches.sh`.
* tests(refactor): `mail_lmtp_ip.bats`
- Converted to new testing conventions and common container helpers.
- `ENABLE_POSTFIX_VIRTUAL_TRANSPORT` was not relevant, dropped.
- Revised test cases, logic remains the same.
- Large custom config used was not documented and doesn't appear to serve any purpose. Simplified by replacing with a single modification with `user-patches.sh`.
- Added some additional comments for context of test and improvements that could be made.
* tests(chore): Adjust comments
The comment from `mail_hostname` provides no valid context, it was likely copied over from `tests.bats` in Oct 2020 by accident.
The email sent is just for testing, nothing relevant to LMTP.
---
Added additional comment for test to reference extra information from.
* tests(chore): Update similar log line matching
Extracts out the match pattern and formatting commands into separate vars (reduces horizontal scrolling), and includes extra docs about what the matched line should be expected to look like.
* fix: Workaround `postconf` write settle logic
After updating `main.cf`, to avoid an enforced delay from reading the config by postfix tools, we can ensure the modified time is at least 2 seconds in the past as a workaround. This should be ok with our usage AFAIK.
Shaves off 2+ seconds roughly off each container startup, reduces roughly 2+ minutes off tests.
* chore: Only modify `mtime` if less than 2 seconds ago
- Slight improvement by avoiding unnecessary writes with a conditional check on the util method.
- Can more comfortably call this during `postfix reload` in the change detection cycle now.
- Identified other tests that'd benefit from this, created a helper method to call instead of copy/paste.
- The `setup email restrict` command also did a modification and reload. Added util method here too.
* tests(fix): `mail_smtponly.bats` should wait for Postfix
- `postfix reload` fails if the service is not ready yet.
- `service postfix reload` and `/etc/init.d/postfix reload` presumably wait until it is ready? (as these work regardless)
* chore: Review feedback - Move reload method into utilities
While working on tests, I noticed that some of the configs being mounted were adding a few seconds to the start-up time of each container. Notably `postfix-*` and `dovecot.conf` config files, which have been extracted out into their own tests with those files moved into a separate config folder.
`tests.bats` has been adapted to the common setup helper, and removed ENV no longer required to run those tests. Future PRs will extract out more tests.
Review may be easier via individual commit diffs and their associated commit messages describing relevant changes.

tests(chore): `tests.bats` - Remove redundant config
===
- ONEDIR volume support no longer relevant, this should have been dropped.
- ClamAV ENV no longer relevant as related tests have been extracted already.
- Same with the some of the SpamAssassin ENV config.
- `VIRUSMAILS_DELETE_DELAY` is tested in the file, but doesn't use this ENV at all? (runs a separate instance to test the ENV instead)
- Hostname updated in preparation for migrating to new test helpers. Relevant test lines referencing the hostname have likewise been updated.
```
```markdown
tests(chore): `tests.bats` - Convert to common setup
===
ENV remains the same, but required adding `ENABLE_AMAVIS=1` to bring that back, while the following became redundant as they're now defaulting to explicitly disabled in the helper method:
- `ENABLE_CLAMAV=0`
- `LOG_LEVEL=debug`
- `ENABLE_UPDATE_CHECK=0`
- `--hostname` + `--tty` + standard `--volume` lines
- `-e` option expanded to long-name `--env`, and all `\` dropped as no longer necessary.
`wait_for_finished_setup_in_container` is now redundant thanks to `common_container_setup`.
```
```markdown
tests(refactor): `tests.bats` - Extract out Dovecot Sieve tests
===
Sieve test files relocated into `test/config/dovecot-sieve/` for better isolation.
`dovecot.sieve` was not using the `reject` import, and we should not encourage it? (docs still do):
https://support.tigertech.net/sieve#the-sieve-reject-jmp
```
```markdown
tests: `tests.bats` - Extract out `checking smtp` tests
===
Migrated to the standard template and copied over the original test cases with `_run_in_container` adjustment only.
Identified minimum required ENV along with which mail is required for each test case.
```
```markdown
tests(refactor): `smtp-delivery.bats`
===
- Disabled `ENABLE_SRS=1`, not necessary for these tests.
- Added a SpamAssassin related test (X-SPAM headers) which requires `SA_TAG` to properly pass (or `ENABLE_SRS=1` to deliver into inbox).
- Many lines with double quotes changed to single quote wrapping, and moving out `grep` filters into `assert_output --partial` lines instead.
- Instead of `wc -l` making failures less helpful, switch to the helper method `_should_output_number_of_lines`
- x2 `assert_output` with different EOF style of usage was not actually failing on tests when it should. Changed to assert partial output of each expected line, and count the number of lines instead.
- Added additional comments related to the test cases with a `TODO` note about `SPAMASSASSIN_SPAM_TO_INBOX=1`.
- Revised test case names, including using the common prefix var.
- `tests.bats` no longer needs to send all these emails, no other test cases require them. This affects a test checking a `/mail` folder exists which has been corrected, and a quotas test case adjusted to expect an empty quota size output.
```
```markdown
tests: `tests.bats` - Extract out test cases for config overrides
===
Slight improvement by additionally matching `postconf` output to verify the setting is properly applied.
```
```markdown
tests: `tests.bats` - Extract out Amavis SpamAssassin test case
===
Removes the need for SpamAssassin ENV in `tests.bats`.
```
</details>
- `disabled_clamav_spamassassin`:
- Just shuffling the test order around, and removing the restart test at the end which doesn't make sense.
- `postscreen`:
- Now uses common helper for getting container IP
- Does not appear to need the `NET_ADMIN` capability?
- Reduced startup time for the 2nd container + additional context about it's relevance.
- Test cases are largely the same, but refactored the `nc` alternative that properly waits it's turn. This only needs to run once. Added additional commentary and made into a generic method if needed in other tests.
- `fail2ban`:
- Use the common container IP helper method.
- Postscreen isn't affecting this test, it's not required to do the much slower exchange with the mail server when sending a login failure.
- IP being passed into ENV is no longer necessary.
- `sleep 5` in the related test cases doesn't seem necessary, can better rely on polling with timeout.
- `sleep 10` for `setup.sh` also doesn't appear to be necessary.
- `postgrey`:
- Reduced POSTGREY_DELAY to 3, which shaves a fair amount of wasted time while still verifying the delay works.
- One of the checks in `main.cf` doesn't seem to need to know about the earlier spamhaus portion of the line to work, removed.
- Better test case descriptions.
- Improved log matching via standard method that better documents the expected triplet under test.
- Removed a redundant whitelist file and test that didn't seem to have any relevance. Added a TODO with additional notes about a concern with these tests.
- Reduced test time as 8 second timeouts from `-w 8` don't appear to be required, better to poll with grep instead.
- Replaced `wc -l` commands with a new method to assert expected line count, better enabling assertions on the actual output.
- `undef_spam_subject`:
- Split to two separate test cases, and initialize each container in their case instead of `setup_file()`, allowing for using the default `teardown()` method (and slight benefit if running in parallel).
- `permit_docker`:
- Not a parallel test, but I realized that the repeat helper methods don't necessarily play well with `run` as the command (can cause false positive of what was successful).
- The usual serial to parallel test conversion to utilize the `setup.bash` common setup structure, and adding a `TEST_PREFIX` var for each test case to leverage.
- Standardize on parallel test naming conventions for variables / values.
- More consistent use of `bash -c` instead of `/bin/bash -c` or `/bin/sh -c`.
- Using the `_run_in_container` helper instead of `run docker exec ${CONTAINER_NAME}`.
- Updates tests to use the `check_if_process_is_running` helper.
---
chore: Revise inline docs for the `ssl_letsencrypt` test
- Moves the override to be in closer proximity to the `initial_setup` call, and better communicates the intent to override.
- Removes top comment block that is no longer providing value or correct information to maintainers.
- Revised `acme.json` test case inline doc comments.
- Introduced `CONTAINER_NAME` and `TEST_NAME_PREFIX` as new vars for better managing test consistency (DRY).
- `CONTAINER_NAME` replaces any repeated container name with the variable. The value will differ slightly as the prior prefix (`mail_`) has been changed to `dms-test-`.
- `TEST_NAME_PREFIX` provides a prefix value for each `@test` description string.
---
chore: Add a reference template for tests
Allows for using `load` with an absolute path instead of a relative one, which makes it possible to group tests into different directories.
Parallel tests differ slightly, loading the newer `helper/common.bash` and `helper/setup.bash` files instead of the older `test_helper/common.bash` which serial tests continue to use.
- `test_helper.bats` needs more work than this PR provides to be compatible with parallel tests, so must remain as a serial test for now.
- `spam_bounced.bats` had failures as a serial test, but works well converted to a parallel test in a future commit.
