How to unit test an authorization redirect with Laravel?

I have manually tested the scenario I want:

Admin Users can go to the /codes section of the site. Normal users are redirected (302) back to the /dashboard and have a message Sorry you are not allowed there when they go to /qr.

Manual testing passes, yet laravel testing fails.

I am using laravel 5.1

Test for the admin user:

public function testAdminViewCodes()
    {
        //create an admin user
        $user = factory(App\User::class, 'admin')->create();

        $this->actingAs($user)
            ->visit('/codes')
            ->seePageIs('/codes')
            ->see('Codes');
    }

Test for normal user:

    public function testNormalViewCodesFail()
    {
        //create a normal user
        $normal_user = factory(App\User::class)->create();

        //TODO: Fix this failing test FFS

        $this->actingAs($normal_user)
             ->visit('/qr')
             ->seePageIs('/dashboard')
             ->see('Sorry you are not allowed there');
}

test results;

There was 1 failure:

1) AdminTest::testNormalViewQRCodesFail
Did not land on expected page [http://localhost/dashboard].
