We've created a SimpleTest_controller in Kohana
and it gets the test from a directory tests
define ( 'SIMPLE_TEST', '../tools/simpletest/');
require_once(SIMPLE_TEST . 'unit_tester.php');
require_once(SIMPLE_TEST . 'reporter.php');
require_once( SIMPLE_TEST . 'mock_objects.php');
class SimpleTest_Controller extends Controller {
  function index() {
    $this->runall();
  }
  function runall() {
    $sDir = '../tests/';
    $rDir = opendir( $sDir );
    while ( $sFile = readdir( $rDir ) ) {
      if ( $sFile != '.' && $sFile != '..' ) {
        $this->run( $sFile );
      }
    }
  }
  function run ( $sTests ) {
    $sDir = '../tests/' . $sTests .'/';
    $rDir = opendir( $sDir );
    $test = new GroupTest( $sTests );
    while ( $sFile = readdir( $rDir ) ) {
      if ( $sFile != '.' && $sFile != '..' && !preg_match('/~\d+~/', $sFile) ) {
        include_once($sDir . $sFile);
        $test->addTestCase( substr($sFile, 0, -4 ) );
      }
    }
    $test->run( new HtmlReporter() );
  }
}
you can call domain.com/simpletest to run all
or you can call domain.com/simpletest/run/account if you have a accountfolder in your testfolder
