[Socialite] Need help testing controller method that uses Socialite's userFromToken

[furatamasensei]

I have been looking for about a week and did some trial and errors but still can't find any solution for this. All I want to do is to assert the returned response from the endpoint that points to a method loginDriver inside my AuthController, but the Socialite implementation was triggered and throws an exception.

The implementation works when I test it manually using real device but I need it to be tested via PHPUnit.

I went to the docs about Mocking, but I'm not sure what to put in shouldReceive for this to work. To help you get a better idea, please have a look at my implementation.

Any kind of help would be very appreciated.

AuthTest.php

public function test_user_can_login_using_auth_driver()
{
    $response = $this->postJson(route('auth.login.driver'), [
        'driver' => 'google',
        'driver_token' => "this is generated natively on client's device (android/ios), how can i fake this????",
        'device_name' => "someone's android/ios"
    ]);

    $response->assertOk();
    $response->assertJsonStructure(['access_token', 'user']);
}

AuthController.php

/**
 * Authenticate the user using auth driver like google and facebook.
 *
 * Since we are working with devices that natively support social auth,
 * user can just select their account from there and it will generate an
 * access token for each login method (driver) they choose.
 * 
 * All we need to do here is to check if the token is valid and returns their data,
 * and check if it has been registered locally in the database, if it's none,
 * then create a new account for them. No need to redirect to anywhere.
 * 
 * @param  \App\Http\Requests\RequestLoginDriver  $request
 * @return \Illuminate\Http\Response
 */
public function loginDriver(RequestLoginDriver $request)
{
    $soci = Socialite::driver($request->driver)->userFromToken($request->driver_token);

    if (!$soci) {
        throw ValidationException::withMessages([
            'messages' => ['The given credentials does not match any records']
        ]);
    }

    $user = User::firstOrCreate(
        ['email' => $soci->getEmail()],
        ['name' => $soci->getNickname(), 'password' => Hash::make(Str::uuid())]
    );

    $token = $user->createToken($request->device_name)->plainTextToken;

    return response()->json([
        'access_token' => $token,
        'user' => $user,
    ]);
}

RequestLoginDriver.php

class RequestLoginDriver 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 [
            'driver' => 'required|string|in:google,facebook',
            'driver_token' => 'required|string',
            'device_name' => 'required|string',
        ];
    }
}
