laravel testing fails when testing passport oauth2 with virtual database - laravel

Question

I'm using virtual test database for my testing. my API is working with postman. but creating problem when writing test. when I execute the test it shows a long list of error containing the following message below-
"message": "Client error: POST http://localhost/oauth/token resulted
in a 401 Unauthorized
response:\n{\"error\":\"invalid_client\",\"message\":\"Client
authentication failed\"}
here is my route-
Route::post('/v1/create', 'API\v1\UserController#register');
here is my controller
public function register(Request $request)
{
$validator = Validator::make($request->all(), [
'name' => ['required', 'string', 'max:255'],
'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
'password' => ['required', 'string', 'min:6', 'confirmed'],
]);
if ($validator->fails()) {
return response()->json(['error'=>$validator->errors()], 401);
}
$input = $request->all();
$input['password'] = bcrypt($input['password']);
$user = User::create($input);
$http=new Client;
$response=$http->post(url("/oauth/token"),[
'form_params'=>[
'grant_type' =>'password',
'client_id' =>$request->client_id,
'client_secret' =>$request->client_secret,
'password' =>$request->password,
'username' =>$request->email,
'scope' =>''
]
]);
// return response()->json(['success'=>$response], $this->successStatus);
return $response;
}
and here is my test-
<?php
namespace Tests\Feature\API\v1;
use Tests\TestCase;
use Illuminate\Foundation\Testing\WithFaker;
use Illuminate\Foundation\Testing\RefreshDatabase;
use App\User;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use PharIo\Manifest\Email;
class UserTest extends TestCase
{
use WithFaker;
use DatabaseMigrations;
public $mockConsoleOutput = false;
/** #test */
public function a_user_can_create_user(){
$user= factory(User::class)->create(); //create user
$login=$this->actingAs($user,'api'); //user login with api
//create password grant client
$this->artisan('passport:client', ['--password' =>true, '--no-interaction' => true, '--redirect_uri'=>'http://localhost', '--name'=>'test client']);
// fetch client for id and secret
$client = \DB::table('oauth_clients')->where('password_client', 1)->first();
// dd($client->getData());
$email=$this->faker->email();
$password=$this->faker->password;
$newUser=$this->json('POST','/api/v1/create',[
'grant_type' =>'password',
'client_id' => $client->id,
'client_secret' => $client->secret,
'name' => $this->faker->name(),
'email' => $email,
'password' => $password,
'password_confirmation' => $password,
'remember_token' => str_random(10),
]);
// ->assertJsonStructure(['access_token', 'refresh_token']);
dd($newUser);
// $this->assertDatabaseHas('users',['email'=>$email]);
// $newUser->assertJsonFragment(['token_type'=>'Bearer']);
}
}
please help me what am I missing

Answer 1

I've solved it by proxying the request. it was happening because- when I was calling the "oauth/token" endpoint with guzzle- that call was treated as real call and test was not working there. so this helped me a lot to solve the problem.
$tokenRequest = Request::create('oauth/token', 'POST',$request->toArray());
$response = Route::dispatch($tokenRequest);
