Ability to configure a container to inject dependencies in PHPat tests

[garak]

Question

I have a Symfony project with some tagged services, and I'd like to enforce that every class implementing a given interface has the expected tag applied in the container.

I was wondering if this could be currently feasible using phpat... I've read the documentation, checked the examples, and got an idea about how a custom rule is built, but in my specific case I'd need something where I could inject the container, which seems not possible to me.

Am I missing something? If not, do you think it could be implemented somehow in the future?
Or maybe you have some alternate suggestions about how could I enforce my costraint?

Thanks in advance

PHPat is framework-agnostic. If your tags are declared via class attribute, you can enforce X classes to apply an attribute (I think not with specific parameters atm), but you cant enforce stuff that requieres the tool to "understand" Symfony.
PHPat is based on PHPStan, you might find easier to write a manual custom rule, probably using the phpstan-symfony extension

I fully understand (and support) the neutrality of this library.
I mentioned my specific case with Symfony just to be as clear as possible.

Anyway, I think that my case could be of more general interest, when someone could need adding a generic dependency (using a constructor injection of any other possible method) when defining a rule

[carlosas]

I'm not sure I understand what you mean by adding a generic dependency. Your test classes can have a constructor and you can add any logic you need as long as the rule methods start by test or have the #[TestRule] attribute, and return a Rule or an iterable of Rules.

That's exactly my point: the constructor is useless if you can't pass arguments

Got it 👌 I added it on the TO-DO list #304

My idea is to configure the PHPStan container by default (with a PSR wrapper) and make the container configurable somehow via config key. I've been playing around but it's still not working #311
