In the CyberSource test environment, you can simulate the specific error messages that you receive from transaction requests. There are both general and processor-specific testing codes and responses. By including specific values in your transaction requests, you can generate specific responses in the transaction reply messages. The simulated environment allows you to become familiar with the reply messages and develop methods for error handling. For more information refer to the implementation guide for the service you are testing.
