Add auto-generated smoke tests

Extracted from https://github.com/Pierstoval/SmokeTesting , as @COil doesn't want a Composer dependency for that, and the concept is straightforward anyway

Thanks for PR @Pierstoval, check out php-cs-fixer errors please.

Done 👌

Hello,

Done 👌

Ok for php-cs-fixer but there are some PHPStan warnings.

To ensure the CI will pass, you can run (with xdebug enabled)

make ci 

Or for phpstan only :

make stan

AutomatedSmokeTest?

[Pierstoval]

Since this test case doesn't cover dynamic route, automation is only related to specific routes, aka the static ones. I think adding "automated" would be too generic and less informative about what it actually does.

[COil]

Not sure these @var annotations are needed with the Symfony PHPStan plugin, to test.

[Pierstoval]

It's indeed not necessary for PHPStan, but it might be necessary for some IDEs that don't understand Symfony's DI rules. Some static analysers relying only on PHPDoc will also understand annotations better. I think we should keep it.

Thanks @Pierstoval :)
