PHPUnit Service Create Trait

A helper trait for PHPUnit 10+ for easier creation of services with dependencies in unit testing

Installation

Simply run

composer require --dev pkly/phpunit-service-create-trait

Currently compatible only with PHPUnit 10 (11?)

Usage

In any of your PHPUnit test cases simply

class MyTestCase extends \PHPUnit\Framework\TestCase {
    use \Pkly\ServiceMockHelperTrait;
    
    private AnyClass $service;
    
    public function setUp(): void {
        $this->service = $this->createRealMockedServiceInstance(AnyClass::class);
    }

    public function testSomething(): void
    {
        $mock = $this->createMock(MyEntity::class);
    
        $this->getMockedService(EntityManagerInterface::class)
            ->expects($this->once())
            ->method('delete')
            ->with($mock);
            
        $this->service->deleteSomething($mock);
    }
}

Any dependencies in the constructor as well as methods marked with Symfony's #[Required] attribute will be automatically plugged in with mocks. This allows you to write complex tests without wasting time updating your construct calls each time you modify something.

Okay, but what if I need to use something custom?

Simply assign the proper parameter name in either $constructor or $required in the appropriate methods. That will use your object instead of creating one for you, keep in mind you cannot retrieve it via $this->getMockedService().

Partial objects?

Sure, works the same, just use createRealPartialMockedServiceInstance instead of createRealMockedServiceInstance, in that case you must also specify the methods to override in your mock. Returned instance is T&MockObject.

Tests? More examples?

I'll add them shortly, for now this code is being used thoroughly in a few of the projects I work at and I grew tired of updating it across multiple repositories. It's also very simple, so I doubt anyone is going to complain.

Feature requests?

Sure, hit me up with an issue if you wish.
