Keep in mind that Sandbox doesn't connect to any external card processors, so if you need to test any error handling, you'd need to enable "Negative Review" on your Sandbox test account via https://developer.paypal.com/ and pass specific amounts / CVV codes to trigger a specific error code.
(For example, sending AMT=100.02 to trigger the 10002 API error code. See the Sandbox User Guide for more details.)
