Method and system of testing software using real time replication

A system comprising:

• a primary computer system configured to execute a software under a simultaneous test of functionality and a separate test of configuration;
• a plurality of secondary computer systems coupled to the primary computer system by way of a computer network, the secondary computer systems configured to execute respective duplicate functional but different configuration copies of the software under test;
• wherein the primary computer system is configured to record a representations of interactions of a predetermined action of a human operator on the software under test, and to send the representations to the plurality of secondary computer systems;
• wherein each secondary computer system is configured to receive the representation and apply, in real time with the response of the software under test to the predetermined action, the representation to the respective duplicate functional but different configuration copy of the software under test;
• wherein each secondary computer system is further configured to analyze a result of a predetermined operation expected by the software under test based on the predetermined action against a result of the application of the representation to the duplicate functional but different configuration copy of the software under test in the secondary computer system;
• and
• wherein the system is configured to alert the human operator when the comparison of the results on the primary and any secondary computer systems indicate unexpected operation of the duplicate functional but different configuration copy of the software under test.

A non-transitory computer-readable media storing a program that, when executed by a processor, causes the processor to:

• observe an both a predetermined action of a human on an application program executed on a first computer system and a response to the predetermined action of the application program to simultaneously and separately test functionality and configuration of the application program;
• send, in real time with the observation, a representation of the predetermined action to a remote computer system coupled to the first computer system by way of a computer network;
• determine a result of the predetermined action between the human and the application program on the first computer system;
• send to the remote computer system an indication of the result of the predetermined action between the human and the application program executed on the first computer system;
• receive from the remote computer system an indication of a relationship between the result of the predetermined action between the human and the application program executed on the first computer system and a result of applying the representation of the predetermined action to a duplicate functional but different configuration copy of the application program executed on the remote computer system;
• and
• alert the human if the comparison of a result obtained by the application program based on the predetermined action and a result obtained by a duplicate functional but different configuration copy of the application program executed on the remote computer system indicates an unexpected result on the remote computer system.
