doing ajax requests in laravel controller tests?

Consider the following test:

public function it_should_not_let_you_access_the_company_end_point_when_not_logged_in() {
    $response = $this->call('GET', 'api/v1/company/');

    $this->assertEquals('302', $response->getStatusCode());
}

This should be an ajax call and the result should be 401 for unauthorized.

My middle ware states:

<?php namespace App\Http\Middleware;

use Closure;
use Illuminate\Contracts\Auth\Guard;

class Authenticate {

    /**
     * The Guard implementation.
     *
     * @var Guard
     */
    protected $auth;

    /**
     * Create a new filter instance.
     *
     * @param  Guard  $auth
     * @return void
     */
    public function __construct(Guard $auth)
    {
        $this->auth = $auth;
    }

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if ($this->auth->guest())
        {
            if ($request->ajax())
            {
                return response('Unauthorized.', 401);
            }

            return redirect()->guest('auth/login');
        }

        return $next($request);
    }

}
