I have a class with the following signature:

class Service
{
    public function __construct(
        Class $a,
        Class $b,
        Class $c
    )

how can I get an instance of it in a test method? the call through the constructor throws the following error

Too few arguments to function Service::__construct(), 0 passed

but in the application itself, this class works, for example, in the command:

class ServiceCommand extends AbstractCommand
{
    protected $service;


    public function __construct(Service $service)
    {
        parent::__construct();
        $this->service = $service;
    }

You need to understand Dependency injection and how the Service container works in Laravel.

How to get an instance of the Service object in a phpunit test-method

Two ways - one for feature testing, one for unit:

Feature

Use the service container to inject dependencies.

$this->service = $this-app->make(Service::class);

Unit

Mock your dependencies - read more about mocking

$mockA = $this->createMock(Class::class);
// ...
$this->service = new Service($mockA...);
