for my codeigniter 3 project i have creating a unit test class with phpunit:
i have following test controller :

PHP Code:

<?php
require_once("C:\\My_PC\\Birim Test\\...\\application\\core\\MY_UserController.php"); 
require_once 'C:\\My_PC\\Birim Test\\...\\config.php';
require_once 'C:\\My_PC\\Birim Test\\...\\application\\tests\\bootstrap.php';

if (!defined('BASE_URL')) {
    define('BASE_URL', 'https://...com/'); 
}
use PHPUnit\Framework\TestCase;

class UserControllerTest extends TestCase {
    protected $CI;

    protected function setUp(): void {
        // Manually load CodeIgniter instance
        $this->CI = &get_instance();
        
        // Load required models and libraries
        $this->CI->load->model('user_model');
        $this->CI->load->library('unit_test');

        // Load the controller manually
        require_once APPPATH . 'controllers/Profil.php';
        $this->controller = new Profil();
    }

    public function testSaveCommentSuccess() {
        // Mock input data
        $_GET['issue'] = 'profil__comment';
        $_GET['report_id'] = 4901; 
        $_GET['comment'] = 'This is a test comment';

        // Mock the model method
        $this->CI->user_model = $this->createMock('User_model');
        $this->CI->user_model->method('update_comment')->willReturn(true);

        // Capture the output
        ob_start();
        $this->controller->save_comment();
        $output = ob_get_clean();

        // Assert the output
        $this->assertJsonStringEqualsJsonString(json_encode(['success' => true]), $output);
    }

    public function testSaveCommentFailure() {
        // Mock input data
        $_GET['issue'] = 'profil__comment';
        $_GET['report_id'] = 4901; 
        $_GET['comment'] = 'This is a test comment';

        // Mock the model method
        $this->CI->user_model = $this->createMock('User_model');
        $this->CI->user_model->method('update_comment')->willReturn(false);

        // Capture the output
        ob_start();
        $this->controller->save_comment();
        $output = ob_get_clean();

        // Assert the output
        $this->assertJsonStringEqualsJsonString(json_encode(['success' => false]), $output);
    }
} 


in bootstrap then i have:

PHP Code:

define('APPPATH', 'C:\\My_PC\\Birim Test\\...\\application\\');
define('ENVIRONMENT', 'testing');

// Include your main configuration file
require_once 'C:\\My_PC\\Birim Test\\...\\config.php'; // Adjust the path as needed
require_once 'C:\\My_PC\\Birim Test\\...\\system\\core\\CodeIgniter.php'; 

// Define BASE_URL if not already defined
if (!defined('BASE_URL')) {
    define('BASE_URL', 'https://....com/'); 
} 


when i ran on local in terminal using:

PHP Code:

vendor/bin/phpunit --bootstrap application/tests/bootstrap.php application/tests/UserControllerTest.php 


i get :

PHP Code:

No direct script access allowed
