refactor: Parallel Tests - `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).

tests(fix): Adjust for local testing conditions (#2606) * tests(fix): Increase some timeouts Running tests locally via a VM these tests would fail sometimes due to the time from being queued and Amavis actually processing being roughly around 30 seconds. There should be no harm in raising this to 60 seconds, other than delaying a failure case which will ripple through other time sensitive tests. It's better to pass when functionality is actually correct but just needs a bit longer to complete. * tests(fix): Don't setup an invalid hostname During container startup `helpers/dns.sh` would panic with `hostname -f` failing. Dropping `--domainname` for this container is fine and does not affect the point of it's test. --- It's unclear why this does not occur in CI. Possibly changes within the docker daemon since as CI runs docker on Ubuntu 20.04? (2020). For clarity, this may be equivalent to setting a hostname of `domain.com.domain.com`, or `--hostname` value truncated the NIS domain (`--domainname`) of the same value. IIRC, it would still fail with both options using different values if `--hostname` was multi-label. I believe I've documented how non-deterministic these options can be across different environments. `--hostname` should be preferred. There doesn't seem to be any reason to actually need `--domainname` (which is NIS domain name, unrelated to the DNS domain name). We still need to properly investigate reworking our ENV support that `dns.sh` manages. --- Containers were also not removing themselves after failures either (missing teardown). Which would cause problems when running tests again. * chore: Normalize white-space Sets a consistent indent size of 2 spaces. Previously this varied a fair bit, sometimes with tabs or mixed tabs and spaces. Some formatting with blank lines. Easier to review with white-space in diff ignored. Some minor edits besides blank lines, but no change in functionality. * fix: `setup.sh` target container under test Some of the `setup.sh` commands did not specify the container which was problematic if another `docker-mailserver` container was running, causing test failures. This probably doesn't help with `test/no_container.bats`, but at least prevents `test/tests.bats` failing at this point.
