1. A method for simulating variable changes, the method comprising: during runtime of a process, recording, by one or more processors, a set of variable changes and a process context; filtering, by one or more processors, sensitive content from the set of variable changes and the process context; importing, by one or more processors, the recorded set of variable changes into a simulator; and executing, by one or more processors, the simulator, to simulate a running sequence of the process using the recorded set of variable changes and the process context.
