1. A method of executing a computer application in a computer architecture, the method comprising: configuring a running environment for managing a preselected script; running a computer application on a first computer architecture having a processing device, a first operating system, and a first browser, including generating a test script from the preselected script and executing the test script on the first browser using the first processing device; transmitting the test script to at least one second computer architecture on a remote device having a second browser different from the first browser, a second operating system different from the first operating system, and a remote control program for executing the test script on the second browser simultaneously while the test script is executed on the first browser, wherein user actions in the first browser are replicated in real time in the second browser; and receiving results from the remote device upon execution of the transmitted test script; wherein the preselected script comprises: a core script that is executed by the system to generate new test scripts for each action by a user in the first browser, a template script that initializes a running environment, and a remote machine configuration script that configures the second computer architecture and the second browser.
