1. At least one computer-readable storage medium comprising instructions that, when executed, cause a system to: receive a task hierarchy from a data store, the task hierarchy comprising a plurality of task entries, each task entry comprising a list of task entries or a task command, the list of task entries comprising probabilities associated with each task entry in the list of task entries, wherein task commands correspond to a simulated environment representing a production environment; and simulate one or more commands in the simulated environment using the task hierarchy, wherein simulating each of the one or more commands comprises traversing through the task hierarchy based on the associated probabilities until a task command is reached and executing the task command as a simulated command in the simulated environment.
