Setup CI

[sgrodzicki]

As mentioned in #169 (comment) this is the foundation for setting up unit tests (to be extended with integration tests).

Probably the most controversial is the bump to PHP 5.6, which is due to the supported versions of the testing framework. On the other hand, PHP 5 has not been supported for a long time, so this is, in my opinion, a good time to move at least a little bit closer to the current supported versions of PHP.

Thanks for the PR!

I fully agree wrt PHP versions; the only reason we have kept that requirement low is because there are still developers using a variety of PHP 5.X versions. Here are the latest stats from Packagist:

I'll dive into this asap.

It's 0% for all of 5.x recently, so perhaps we could use PHPUnit 8 and include PHP 7&8 instead of PHP 5&7?

I'm OK with leaving things as is (>=5.6) as this would enforce that no new syntax (e.g., strict_types) is used while only keeping us from running automated tests against PHP 8. However, if you're willing to drop PHP 5 altogether I'm happy to upgrade all dependencies.

[malle-pietje]

I think we should have PHP 7 as the minimum requirement. We may need to add a note to the readme explaining how users can still use the class with PHP 5 (for all install methods mentioned).

Great! Upgraded to PHPUnit 8 (and as a consequence to PHP 7.2) in d54d18a

[sgrodzicki]

I figured that we can still allow PHP 5 and only run tests for supported PHP versions (>=7.2). Changes in 2a8c353.

[sgrodzicki]

I've added integration tests in eefcb65 which test against every minor version of PHP starting from 7.2 and all UniFi Network Application versions available as Docker images. This currently translates into the following matrix:

PHP / UniFi	stable-5	stable-6	v7.0	v7.1	v7.2	v7.3
7.2	PHP 7.2.34 / UniFi 5.14.23	PHP 7.2.34 / UniFi 6.5.55	PHP 7.2.34 / UniFi 7.0.25	PHP 7.2.34 / UniFi 7.1.68	PHP 7.2.34 / UniFi 7.2.95	PHP 7.2.34 / UniFi 7.3.83
7.3	PHP 7.3.33 / UniFi 5.14.23	PHP 7.3.33 / UniFi 6.5.55	PHP 7.3.33 / UniFi 7.0.25	PHP 7.3.33 / UniFi 7.1.68	PHP 7.3.33 / UniFi 7.2.95	PHP 7.3.33 / UniFi 7.3.83
7.4	PHP 7.4.33 / UniFi 5.14.23	PHP 7.4.33 / UniFi 6.5.55	PHP 7.4.33 / UniFi 7.0.25	PHP 7.4.33 / UniFi 7.1.68	PHP 7.4.33 / UniFi 7.2.95	PHP 7.4.33 / UniFi 7.3.83
8.0	PHP 8.0.28 / UniFi 5.14.23	PHP 8.0.28 / UniFi 6.5.55	PHP 8.0.28 / UniFi 7.0.25	PHP 8.0.28 / UniFi 7.1.68	PHP 8.0.28 / UniFi 7.2.95	PHP 8.0.28 / UniFi 7.3.83
8.1	PHP 8.1.17 / UniFi 5.14.23	PHP 8.1.17 / UniFi 6.5.55	PHP 8.1.17 / UniFi 7.0.25	PHP 8.1.17 / UniFi 7.1.68	PHP 8.1.17 / UniFi 7.2.95	PHP 8.1.17 / UniFi 7.3.83
8.2	PHP 8.2.4 / UniFi 5.14.23	PHP 8.2.4 / UniFi 6.5.55	PHP 8.2.4 / UniFi 7.0.25	PHP 8.2.4 / UniFi 7.1.68	PHP 8.2.4 / UniFi 7.2.95	PHP 8.2.4 / UniFi 7.3.83

@sgrodzicki It would be good to revisit this topic again. I haven't looked into this in great detail but what would the general flow be? Also, how do we determine which controller and site the tests are executed a against for the assertions?

[sgrodzicki]

The test matrix is defined in .github/workflows/test.yml and it looks like v7.4, v7.5, and v8.0 would need to be added. Also, 8.3 for PHP itself. Other than that everything seems to be working fine. Feel free to have a look at the output of those test runs: https://github.com/sgrodzicki/UniFi-API-client/actions/runs/7247262033

[malle-pietje]

Thanks. Looking at the results and the setup of the tests it looks as if you're assuming the localhost is running MongoDB and we have an account with given username and password. Could we obtain the credentials and URL from a file that is outside of source control? Then restrict the tests to the login and other methods.

Forgive the ignorant questions; I'm not that familiar yet with PHP testing 😉

[sgrodzicki]

This setup is meant to run on GitHub Actions but it could certainly be adjusted to run somewhere else (though Docker would be almost identical). Those credentials are defaults from the core components.

[malle-pietje]

Okay, understood. Will dive into this next year 😉

[malle-pietje]

FYI, we've bumped PHP requirement to 7.4 😉

Upgraded to PHP 7.4 and updated dependencies (GitHub Actions & UniFi versions)
