Simulator application on mobile device for integration testing

A mobile device comprising:

• a contactless element;
• a processor;
• and
• a computer readable medium coupled to the processor, the computer readable medium comprising instructions executable by the processor, to cause the mobile device to:
• retrieve, using a simulator application, a first data record from a resource file, the resource file storing a plurality of data records associated with a plurality of user devices, the plurality of data records including at least the first data record and a second data record;
• generate, using the simulator application, a first interaction payload including the first data record;
• provide, using the simulator application, the first interaction payload to a first contactless acceptance application stored on the mobile device;
• transmit, to a first service provider computer, using the first contactless acceptance application, a first interaction message comprising the first interaction payload, wherein the first service provider computer processes a first test interaction using the first data record in the first interaction payload;
• retrieve, using the simulator application, the second data record from the resource file;
• generate, using the simulator application, a second interaction payload including the second data record;
• provide, using the simulator application, the second interaction payload to the first contactless acceptance application stored on the mobile device;
• and
• transmit, to the first service provider computer, using the first contactless acceptance application, a second interaction message comprising the second interaction payload, wherein the first service provider computer processes a second test interaction using the second data record in the second interaction payload.
