PHPUnit and PDOException + Solution

I recently needed to run a test suite against a couple of classes that were making use of PDO.

When I tried to run the I got the following errors in the output for every test

PDOException: You cannot serialize or unserialize PDO instances

There is a quick way around this you just need to add the following lines to the class level doc block

 * @backupGlobals disabled
 * @backupStaticAttributes disabled

A full explanation of these, and other annotations can be found here
