Question

I am using PHPUnit 3.5 and CIUnit with PHING 2.4 for unit testing my CodeIgniter controller functions

The problem is when the function i tested contains a redirect() function, the testcase will stop and will not continue the execution. There is also no available error log for this.

What could be the problem for this? Do i have to download/update PHPUnit specific library?

Any suggestion would be greatly appreciated.

Thanks

Well this would be because the redirect() fn exits after doing a redirect (which is what you should be doing when you do a redirect to stop further code execution while waiting on the browser redirect).

/system/helpers/url_helper.php:

/**
 * Header Redirect
 *
 * Header redirect in two flavors
 * For very fine grained control over headers, you could use the Output
 * Library's set_header() function.
 *
 * @access  public
 * @param   string  the URL
 * @param   string  the method: location or redirect
 * @return  string
 */
if ( ! function_exists('redirect'))
{
    function redirect($uri = '', $method = 'location', $http_response_code = 302)
    {
        if ( ! preg_match('#^https?://#i', $uri))
        {
            $uri = site_url($uri);
        }

        switch($method)
        {
            case 'refresh'  : header("Refresh:0;url=".$uri);
                break;
            default         : header("Location: ".$uri, TRUE, $http_response_code);
                break;
        }
        exit;  <===<<< here is the exit
    }
}

The only way ‘around’ this is to eliminate the exit; after the redirect call.
