implementing PHPUnit Mocking for a Service Class in Laravel 9
I'm wondering if anyone has experience with Hey everyone, I'm running into an issue that's driving me crazy. I am currently working on a Laravel 9 application and trying to unit test a service class that relies on a repository for data fetching. My scenario arises when I'm trying to mock the repository using PHPUnit. I get the following behavior message: `TypeError: Argument 1 passed to App\Services\MyService::__construct() must be an instance of App\Repositories\MyRepository, instance of Mockery\MockInterface given`. I've tried a few things, but I need to seem to get the mock to be recognized as an instance of the correct class. Here is the relevant part of my service class: ```php namespace App\Services; use App\Repositories\MyRepository; class MyService { protected $repository; public function __construct(MyRepository $repository) { $this->repository = $repository; } public function getData() { return $this->repository->fetchData(); } } ``` And here is my test case: ```php namespace Tests\Unit; use Tests\TestCase; use App\Services\MyService; use App\Repositories\MyRepository; use Mockery; class MyServiceTest extends TestCase { public function testGetData() { $mockRepository = Mockery::mock(MyRepository::class); $mockRepository->shouldReceive('fetchData')->once()->andReturn(['data']); $service = new MyService($mockRepository); $result = $service->getData(); $this->assertEquals(['data'], $result); } } ``` I have verified that I have imported `Mockery` correctly and that `MyRepository` is defined. I also tried using the `Mockery::mock()` method both with and without type hinting, but it doesn’t resolve the scenario. Any advice on how to properly mock the repository so that it can be injected into the service class would be greatly appreciated. I'm using PHPUnit 9.5 and Mockery 1.4.4. For context: I'm using Php on Linux. I'd really appreciate any guidance on this. I'm working with Php in a Docker container on Windows 10. How would you solve this? I've been using Php for about a year now. I'm working with Php in a Docker container on Debian.
