Add files to test suite $suite
Uses recursion to scan subdirectories

}Loads test files if they cannot be found by kohana
static function autoload($class)
{
$file = str_replace('_', '/', $class);
if ($file = Kohana::find_file('tests', $file))
{
require_once $file;
}
}Blacklist a set of files in PHPUnit code coverage
array
$blacklist_items
required - A set of files to blacklistUnittest_TestSuite
$suite
= NULL - The test suitestatic public function blacklist(array $blacklist_items, Unittest_TestSuite $suite = NULL)
{

}Configures the environment for testing
Does the following:
static public function configure_environment($do_whitelist = TRUE, $do_blacklist = TRUE)
{
restore_exception_handler();
restore_error_handler();
spl_autoload_register(array('Unittest_tests', 'autoload'));
// As of PHPUnit v3.5 there are slight differences in the way files are black|whitelisted
self::$phpunit_v35 = function_exists('phpunit_autoload');
Unittest_tests::$cache = (($cache = Kohana::cache('unittest_whitelist_cache')) === NULL) ? array() : $cache;
}Creates the test suite for kohana
Unittest_TestSuitestatic function suite()
{
static $suite = NULL;
if ($suite instanceof PHPUnit_Framework_TestSuite)
{
return $suite;
}
Unittest_Tests::configure_environment();
$suite = new Unittest_TestSuite;
// Load the whitelist and blacklist for code coverage
$config = Kohana::$config->load('unittest');
if ($config->use_whitelist)
{
$files = Unittest_Tests::whitelist(NULL, $suite);
}
if (count($config['blacklist']))
{
Unittest_Tests::blacklist($config->blacklist, $suite);
}
// Add tests
$files = Kohana::list_files('tests');
$config = Kohana::$config->load('unittest');
foreach($config->test_blacklist as $bl)
{
unset($files[$bl]);
}
self::addTests($suite, $files);
return $suite;
}Sets the whitelist
If no directories are provided then the function'll load the whitelist set in the config file
array
$directories
= NULL - Optional directories to whitelistUnittest_Testsuite
$suite
= NULL - Suite to load the whitelist intostatic public function whitelist(array $directories = NULL, Unittest_TestSuite $suite = NULL)
{
if (empty($directories))
{
$directories = self::get_config_whitelist();
}
if (count($directories))
{
foreach ($directories as & $directory)
{
$directory = realpath($directory).'/';
}
// Only whitelist the "top" files in the cascading filesystem
self::set_whitelist(Kohana::list_files('classes', $directories), $suite);
}
return $directories;
}Works out the whitelist from the config Used only on the CLI
static protected function get_config_whitelist()
{
$config = Kohana::$config->load('unittest');
$directories = array();
if ($config->whitelist['app'])
{
$directories['k_app'] = APPPATH;
}
if ($modules = $config->whitelist['modules'])
{
$k_modules = Kohana::modules();
// Have to do this because kohana merges config...
// If you want to include all modules & override defaults then TRUE must be the first
// value in the modules array of your app/config/unittest file
if (array_search(TRUE, $modules, TRUE) === (count($modules) - 1))
{
$modules = $k_modules;
}
elseif (array_search(FALSE, $modules, TRUE) === FALSE)

// modules are disabled
$modules = array();
}
$directories += $modules;
}

{

}
