Update FormRequest in Unit Test

Hello.

Today I started wih the unit test in my repository pattern and everything it's ok instead one method: update the information.

UserTest.php

<?php

use App\User;
use App\Http\Controllers\UserController;
use App\Http\Requests\UserRequest;
use App\Repositories\UserRepository;
use App\Services\UserService;
use Illuminate\Support\Facades\Event;
use Illuminate\Http\Request;

class UserRules
{
    public static $rules = array(
        'name' => 'required'
    );
}

class UserTest extends TestCase
{
    public $userController;
    
    public function __construct()
    {
        $userModel = new User();
        $userRepository = new UserRepository($userModel);
        $userService = new UserService($userRepository);
        $this->userController = new UserController($userService);
    }
    
    public function testGetAll()
    {
        Event::fake();
        
        $response = $this->userController->getServices();
        
        $this->assertEquals(200, $response->getStatusCode());
    }
    
    public function testCreate()
    {
        Event::fake();
        
        $request = UserRequest::create(route('users.create'), 'POST',[
            'name'=>'fake name',
            'surname'=>'fake surname',
            'address'=>'fake address'
        ]);
        
        $response = $this->userController->store($request);
     
        $this->assertEquals(302, $response->getStatusCode());
    }
    
    public function testUpdate()
    {
        $request = UserRequest::create(route('users.create'), 'POST',[
            'name'=>'fake name',
            'surname'=>'fake surname',
            'address'=>'fake address'
        ]);
    
        $update = $this->json('PUT', route('users.edit', $request->id),[
            'name'=>$request->name.'_updated'
        ]);
        
        $response = $this->userController->update($update, $request->id);
        
        $this->assertEquals(200, $response->getStatusCode());
    }
        
    public function testDelete()
    {
        Event::fake();
        
        $request = Request::create(route('users.delete'), 'POST', ['id'=>63]);
        
        $response = $this->userController->destroy($request);
        
        $this->assertEquals(200, $response->getStatusCode());
    }
    
    public function testUserWithoutName()
    {
        $user = new User();
        
        $validator = Validator::make(array('address' => 'fake address'), UserRules::$rules);
        
        $this->assertFalse($validator->passes());
    }
    
    public function testUserWithName()
    {
        $user = new User();
        
        $validator = Validator::make(array('name' => 'fake name'), UserRules::$rules);
        
        $this->assertTrue($validator->passes());
    }
}

UserRequest.php

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class UserRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'name' => 'required'
        ];
    }
}

When I trying to update, the error that appears is:

TypeError: Argument 1 passed to App\Http\Controllers\UserController::update() must be an instance of App\Http\Requests\UserRequest, instance of UserTest given, called in C:\Users\XXXXX\tests\UserTest.php on line 79

I think that's ok, but I don't see where must be the error :/
