Как писать phpunit тесты Api в laravel?

public function addResource(Request $request)
    {
        $url = $request->input('url');
        $result = $this->service->saveContent($url);

        if ($result !== null) {
            return response()->json(['status' => 'ok', 'message' => 'Ресурс добавлен', 'data' => $result]);
        }

        return response()->json(['status' => 'error', 'message' => 'Ошибка', 'data' => ['url' => $url]]);
    }

public function testBasicExample()
    {
        $response = $this->json('POST', '/api/resource', ['name' => 'saveContent']);
        $service = $this->createMock(Request::class);
        
        $contentController = new ContentController($service);
       
    }
