Testing withSession() generates an error.

Hi! I am testing a method of my controller which displays a json only if an established session is found.

To perform the test I am using the following code since the path can be accessed only if the logged_in variable exists in session

public function testERP(){
        $values = [
            'logged_in' => TRUE,
            'username' => 'foo'
        ];

        $response = $this->withSession($values)->get('/');
        
        $response->assertSessionHas('logged_in',TRUE);
        print_r($response->getJSON());
        $response->assertStatus(200);
}

In my class it's like the following:

use CodeIgniter\API\ResponseTrait;
class Dash extends BaseController
{
    use ResponseTrait;
    public function index()
    {
        $session = \Config\Services::session();

        if($session->logged_in == TRUE){

            $data = [
                [
                    'id' => 1,
                    'username' => 'foo1',
                ],
                [
                    'id' => 2,
                    'username' => 'foo2',
                ],
            ];
            return $this->respond($data,200);
        }else{
            throw \CodeIgniter\Exceptions\PageNotFoundException::forPageNotFound();
        }
    }
}

The test only works correctly if I don't use the logged_in comparison but it is not correct because there must be a session to access the resource.

@luispastendev The problem is that your test case has already defined the session parameters yet your session handler is trying to modify the parameters. I recommend using MockSession during testing, especially Feature Tests. I actually just sent over a PR to mock the session by default (#3193) but fi you don't want to wait for that you could borrow some of the code to do it yourself.

Hi @MGatner use your PR code and I managed to circumvent the sessions to test. I thank you very much for your help :)

Glad to hear it! Is this issue closed then?
