Title: TESTING SOFTWARE CODE IN A PRODUCTION ENVIRONMENT
Abstract:
Embodiments of the invention are directed to techniques for redirecting data streams from a production environment to validate non-production software code. In some embodiments, a front-end computer executing a first version of software can receive a request message from a requesting computer, generate a request payload using the request message, transmit the request payload to a processor computer, receive a response payload from the processor computer, generate a reply message using the response payload, and provide, to a validation computer that is executing a second version of the software, the request message, the request payload, and the response payload. The validation computer can generate a modified request payload using the request message and a modified reply message using the response payload. To detect potential errors in the second version, the modified request payload is compared with the request payload and the modified reply message is compare with the reply message.
