我需要测试以下功能：

[...]
public function createService(ServiceLocatorInterface $serviceManager)
{

    $firstService = $serviceManager->get('FirstServiceKey');
    $secondService = $serviceManager->get('SecondServiceKey');

    return new SnazzyService($firstService, $secondService);
}
[...]

我知道，我可以这样测试：

class MyTest extends \PHPUnit_Framework_TestCase
{
    public function testReturnValue()
    {
        $firstServiceMock = $this->createMock(FirstServiceInterface::class);
        $secondServiceMock = $this->createMock(SecondServiceInterface::class);

        $serviceManagerMock = $this->createMock(ServiceLocatorInterface::class);

        $serviceManagerMock->expects($this->at(0))
             ->method('get')
             ->with('FirstServiceKey')
             ->will($this->returnValue($firstService));

        $serviceManagerMock->expects($this->at(1))
             ->method('get')
             ->with('SecondServiceKey')
             ->will($this->returnValue($secondServiceMock));

        $serviceFactory = new ServiceFactory($serviceManagerMock);

        $result = $serviceFactory->createService();
    }
    [...]

或者

[...]
public function testReturnValue()
{
    $firstServiceMock = $this->createMock(FirstServiceInterface::class);
    $secondServiceMock = $this->createMock(SecondServiceInterface::class);

    $serviceManagerMock = $this->createMock(ServiceLocatorInterface::class);

    $serviceManagerMock->expects($this->any())
         ->method('get')
         ->withConsecutive(
            ['FirstServiceKey'],
            ['SecondServiceKey'],
         )
         ->willReturnOnConsecutiveCalls(
            $this->returnValue($firstService),
            $this->returnValue($secondServiceMock)
         ); …
