Set headers on a request from a feature Test

Hi, I am creating an API with code igniter with TDD. However when I came to the authentication I got a problem: I would like to authenticate with bearer token in the headers but I found not way to change headers from test requests to include the token.

Is there anyway to do that?

CodeIgniter also provides a Response class that is an object-oriented representation of the HTTP response.
This gives you an easy and powerful way to construct your response to the client:

PHP Code:

use CodeIgniter\HTTP\Response;

class
{
    $response = service('response');

    $response->setHeader('Content-type', 'text/html');

    // Sends the output to the browser
    // This is typically handled by the framework
    $response->send();
}
