Brennan Kinney 2cd534a1ab tests(CI): Adjust Makefile & GHA workflow to support new test layout
These updates support running tests that have been relocated into `serial` and `parallel/set*` directories.

- `make tests` now calls the two make targets beneath it. The only difference is that `serial` continues the "1 test at a time" approach used prior to this PR, while the `parallel` target increases the `--jobs` arg to run multiple tests concurrently (_configured by `PARALLEL_JOBS`_).
- The `test/%` target leverages Bash syntax magic to ease running single tests without providing the exact path.
- This syntax also supports providing multiple test names (eg: `make test/clamav,template`) to run.
- `**` (globstar) allows for future improvements that can group multiple test files into sub-directories by their scope (eg: anti-spam, ssl, etc).

---

chore: Add `shopt -s globstar` to other targets
I realized that other targets should have this as well in case it is not set.
It is better to be more explicit here than to have weird errors due to `**` not expanding properly.

fix(Makefile):  Add back `.PHONY` targets

I encountered `make` telling me the target was already up-to-date, which of course is nonsense.
I therefore added back the `.PHONY` targets to ensure tests are always run.

docs: Added instructions for running  a single test

Coding Style

When refactoring, writing or altering scripts or other files, adhere to these rules:

  1. Adjust your style of coding to the style that is already present! Even if you do not like it, this is due to consistency. There was a lot of work involved in making all scripts consistent.
  2. Use shellcheck to check your scripts! Your contributions are checked by GitHub Actions too, so you will need to do this. You can lint your work with make lint to check against all targets.
  3. Use the provided .editorconfig file.
  4. Use /bin/bash instead of /bin/sh in scripts

Tests

To run the test suite, you will need to

  1. Install Docker
  2. Install jq (under Ubuntu, use sudo apt-get -y install jq)
  3. Execute git submodule update --init --recursive if you haven't already initialized the git submodules
  4. Execute make clean all

!!! info "Can I use MacOS?"

We do not support running linting, tests, etc on macOS at this time. Please use a linux VM.

??? tip "Running a Specific Test"

To run a specific test, use `make build generate-accounts test/<TEST NAME>`, where `<TEST NAME>` is the file name of the test (_for more precision use a relative path: `test/test/<PATH>`_) excluding the `.bats` suffix.

To run only the tests in `template.bats`, use `make test/template` (or `make test/parallel/set2/template`).

Documentation

You will need to have Docker installed. Navigate into the docs/ directory. Then run:

docker run --rm -it -p 8000:8000 -v "${PWD}:/docs" squidfunk/mkdocs-material

This serves the documentation on your local machine on port 8000. Each change will be hot-reloaded onto the page you view, just edit, save and look at the result.
