Setting test items in CodeIgniter Unit Test not effecting report output - php

Question

I'm running CodeIgniter 2.0 and I have a test controller setup with this code in the index function. It seems like no matter what I put in the "set_test_items" variable, the report never changes. It always show all of the possible information regarding the test. I feel like I must be missing something blatantly obvious here. What am I missing?
$this->unit->set_test_items(array('test_name', 'result'));
$this->_test_user_lib();
$this->_test_user_model();
echo $this->unit->report();
Also, I just tried to var_dump() on the visible items when the report is generated and the array only contains the two things I passed in, so it is being set correctly.

Answer 1

The set_test_items() affects only the run() methods, not report(). The following code will show only the items you specified in set_test_items():
echo $this->unit->run(1 + 1, 2, 'One plus one');
But the following will show all items:
echo $this->unit->report();
Hope this helps.

You can extend the Unit_class library to fix the run method.
Here is an example using the array helper "elements" to keep only the elements in >_test_items_visible.
Note: This way, you have to set the visible items BEFORE run the tests.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Unit_test extends CI_Unit_test
{
/**
* Llamamos al constructor del padre
*
*/
public function __construct()
{
parent::__construct();
}
/**
* Reemplazamos la función RUN
*/
function run($test, $expected = TRUE, $test_name = 'undefined', $notes = '')
{
// Sacamos la versión
$CI =& get_instance();
$CI->load->helper('array');
if ($this->active == FALSE)
{
return FALSE;
}
if (in_array($expected, array('is_object', 'is_string', 'is_bool', 'is_true', 'is_false', 'is_int', 'is_numeric', 'is_float', 'is_double', 'is_array', 'is_null'), TRUE))
{
$expected = str_replace('is_float', 'is_double', $expected);
$result = ($expected($test)) ? TRUE : FALSE;
$extype = str_replace(array('true', 'false'), 'bool', str_replace('is_', '', $expected));
}
else
{
if ($this->strict == TRUE)
$result = ($test === $expected) ? TRUE : FALSE;
else
$result = ($test == $expected) ? TRUE : FALSE;
$extype = gettype($expected);
}
$back = $this->_backtrace();
// Only visible elements
$report[] = elements
(
$this->_test_items_visible, array
(
'test_name' => $test_name,
'test_datatype' => gettype($test),
'res_datatype' => $extype,
'result' => ($result === TRUE) ? 'passed' : 'failed',
'file' => $back['file'],
'line' => $back['line'],
'notes' => $notes
)
) ;
$this->results[] = $report;
return($this->report($this->result($report)));
}
}

Instead of running the report() method
echo $this->unit->report();
you can run the result() method:
echo $this->unit->result();
This will give you just the items you have selected but in a raw data format (ie. an associative array) this is probably better because the format of the report isn't that great. You can then load them into a view and format them how you want:
$data['test_results'] = $this->unit->result();
$data['title'] = 'Pricing Test';
$this->load->view('header');
$this->load->view('tests/index', $data);
