SimpleTester on CodeIgniter fails with "Class 'GroupTest' not found" - unit-testing

Question

I'm trying to do a clean install SimpleTester on a new CodeIgniter application, following the instructions here: http://codeigniter.com/wiki/SimpleTester_-_Unit_testing_library
Everything's fine until step 6, when I add "simpletester" to the list of libraries that are autoloaded. As soon as I do that, visiting any page simply results in:
Fatal error: Class 'GroupTest' not found in
/path/to/app/application/libraries/simpletester.php on line 84
Grepping through the code for GroupTest I only see it referenced in comments, and in a readme file which states the following:
The GroupTest has been renamed TestSuite (see below).
It was removed completely in 1.1 in favour of this
name.
I tried modifying line 84 to replace GroupTest with TestSuite, but then I get the following error:
Fatal error: Call to undefined method TestSuite::addTestFile() in
/home/path/to/app/application/libraries/simpletester.php
on line 96
Is this a bug on their end? Has anyone seen this before?

Answer 1

I have run into the same issue. The GroupTest class can be found in test_case.php of version 1.0.1 of SimpleTest:
http://sourceforge.net/projects/simpletest/files/simpletest/simpletest_1.0.1/
Unfortunately, simply inserting v1.0.1 into the libraries folder doesn’t solve all the world’s problems. I no longer get the “Fatal error: Class ‘GroupTest’ not found ...” error, but I do get a segmentation fault and my site no longer works.
I have briefly tried to track down the issue but to no avail.
Note: I also responded on the CodeIgniter Wiki page containing the same question.

Answer 2

I had the same problem with a current project and found that the problem is that GroupTest was replaced with TestSuite which works a little differently.
This is the library code I use:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
$libraryDir = APPPATH . 'libraries/simpletest';
if(!is_dir($libraryDir))
exit("Simpletest must be located in \"$libraryDir\"");
require_once $libraryDir . '/unit_tester.php';
require_once $libraryDir . '/mock_objects.php';
require_once $libraryDir . '/collector.php';

Works fine for me I haven't tested all the different reporters yet though. But the default one works fine.
And this is how I use it:
$this->load->library('simpletester');
echo $this->simpletester->Run();
And my config file is:
$config['testDir'] = APPPATH . 'tests';
$config['runFromIPs'] = '127.0.0.1';
$config['reporter'] = 'HtmlReporter';
$config['autorun'] = false;
$config['fileExtension'] = 'php';
$config['testTitle'] = 'My Unit Tests';
