Computer and conduit for system testing

A testing computer comprising:

• a processor;
• a memory;
• and
• a computer-readable medium coupled to the processor, the computer-readable medium comprising code executable by the processor for implementing a method comprising:
• receiving an interaction input message from a mobile device, wherein the mobile device previously received the interaction input message from an access device for an interaction, the mobile device being in short-range communication with the access device;
• determining, using a set of logic emulating a specific type of interaction device, an interaction output message based on the interaction input message;
• and
• transmitting the interaction output message to the mobile device, wherein the mobile device forwards the interaction output message to the access device.

A method comprising:

• receiving, by a mobile device, an interaction input message from an access device for an interaction, the access device being in short-range communication with the mobile device;
• transmitting, by the mobile device, the interaction input message to a testing computer;
• receiving, by the mobile device, an interaction output message from the testing computer, wherein the testing computer determines, using a set of logic emulating a specific type of interaction device, the interaction output message based on the interaction input message;
• and
• providing, by the mobile device, the interaction output message to the access device.
