how to unit test a controller in laravel? - laravel

Question

This is the test function
public function testCreateSuccess(){
$user=['first_name'=>"heba",'last_name'=>"chakaron",'email'=>"hebachakaron#gmail.com",'password'=> "123456"];
$userReturned=['first_name'=>"heba",'last_name'=>"chakaron",'email'=>"hebachakaron#gmail.com",'password'=> Hash::make('123456')];
$userRequest = UserRegisterRequest::create("http://127.0.0.1:8000/api/users/", 'POST',[
'first_name'=>"heba",
'last_name'=>"chakaron",
'email'=>"hebachakaron#gmail.com",
'password'=>'123456',
'password_confirmation'=>'123456'
]);
/**
* #var UserService|\Mockery\MockInterface|\Mockery\LegacyMockInterface
*/
$mock=Mockery::mock(UserService::class);
$mock->shouldReceive('create')->with($user)
->once()
->andReturn($userReturned);
$this->userController=new UserController($mock);
$this->app->instance('App\Services\UserService', $mock);
$created=$this->userController->create($userRequest);
$this->assertSame($created['password'],$userReturned['password']);
}
This is the controller
class UserController extends Controller
{
//
public function __construct(UserService $userService)
{
$this->userService = $userService;
}
public function create(UserRegisterRequest $request)
{
$data = $this->userService->create($request->validated());
return HTTPResponse::ok($data);
}
}
This is the UserRegisterRequest
class UserRegisterRequest extends FormRequest
{
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'first_name' => 'required|string|max:255',
'last_name' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'password' => 'required|string|min:6|confirmed',
];
}
}
When I run this testCreateSuccess it return There was 1 error:
Tests\Unit\UserTest::testCreateSuccess
Error: Call to a member function validated() on null
and the error is on the line $created=$this->userController->create($userRequest)
