ProxyMock

THIS PACKAGE IS ABANDONNED, _(*1)

To replace a service of the Symfony container with a mock make a public alias on the service and then you're able to set a mock for it in the test case (if you have access to the container which is the case in ̀Symfony's KernelTestCase)., _(*2)

config/services.yaml, _(*3)

services:
    my.service:
        class: My\Service

config/services_test.yaml, _(*4)

services:
    my.service.test:
        alias: my.service
        public: true

Your test case extends KernelTestCase, _(*5)

use My\Service;
use Symfony\Bundle\FrameworkBundle\Test\KernelTestCase;

final class ConsumeUserMessagesFromCoreTest extends KernelTestCase
{
    public function testSomething(): void
    {
        // Access the service over the public alias defined in "services_test.yaml"
        self::$container->set('my.service.test', $this->getMockBuilder(Service::class)->getMock());
    }
}

This library helps to create a proxy instance of a class which then can hold a PHPUnit mock of it. That way you can manipulate the mock which sits inside the proxy class but never have to change the proxy class., _(*7)

This can be useful for example in cases of read-only containers where you can't override services at runtime. (The dependency injection container component of Symfony 4 will most likely behave like that.), _(*8)

class Foo { ... }

$factory = new ProxyMockFactory();
$proxyMock = $factory->create(Foo::class);

// In a PHPUnit test case
$mock = $this->getMockBuilder(Foo::class)
    ->disableOriginalConstructor()
    ->getMock();

$proxyMock->setMock($mock);
