globalsBackup causes: PDOException: You cannot serialize or unserialize PDO instances。
在PHPUnit/Frameword/TestCase.php文件中,有一行protected $backupGlobals = TRUE;
把backupGlobals 改为false即可解决这个问题。不过从PHPUNIT开发小组成员的建议来看,他们是不支持用修改backupGlobals的值来解决这个问题的。
The majority of users of PHPUnit expects it to work as it does when the backup of $GLOBALSfeature is enabled. This is why it is enabled by default.
If your tests exercise code that puts unserializable objects into $GLOBALS you can disable the feature.
From a software design perspective, you should not have a global instance of PDO to begin with.
所以更好的解决方法就是在:
$db = SmartPHP_Db::factory($dbConfig);
SmartPHP_Pool::set("db" , $db);
SmartPHP_Db_Table::setDefaultAdapter($db);
这段代码之后,再添加一句:
unset($db);
这样子就完美解决了You cannot serialize or unserialize PDO instances这个问题。
