POCodeIgniter sess_destroy does not delete user_data session?
text
Body
copied!<p>I am creating test case for my CodeIgniter app. However I just found something that I thought should not be happen :</p> <p>in login.php controller : </p> <pre><code>public function logout() { $this->session->sess_destroy(); redirect('/'); } </code></pre> <p>So I just created a test to just make sure that session is really destroyed :</p> <pre><code>public function test_logout() { $this->CI = set_controller('login'); // make sure that all session is destroyed $this->CI->session->set_userdata('test_session', 'some_value'); $this->CI->logout(); // userdata 'test_session' should be removed! $this->assertTrue(($this->CI->session->userdata('test_session')==null || $this->CI->session->userdata('test_session')=='')); } </code></pre> <p>However I find that upon running the test case, my test case fails! Upon debug on the last line of test case, I found that the userdata is still exist with value = 'some_value'. I thought that sess_destroy should also delete all the set user data, as per what they described in their <a href="http://ellislab.com/codeigniter%20/user-guide/libraries/sessions.html" rel="nofollow">website documentation</a>:</p> <blockquote> <p>This function should be the last one called, and even flash variables will no longer be available. If you only want some items destroyed and not all, use unset_userdata().</p> </blockquote> <p>I am using Kenji's CIUnit for unit testing. Is this the correct behaviour or is there something that I missed?</p>
