A command accumulation tool, a testing tool for a queue, and a method, are provided, which, for example, may cause commands to accumulate in queue(s). In one embodiment, a testing tool comprises an I/O interface for connecting with a target having the queue(s); and an I/O interface for connecting with initiator(s). Trigger logic intercepts a predetermined response at the target I/O interface from a target to an initiator with respect to a command of the initiator, and asserts a trigger signal. Outbound logic responds to the trigger signal, providing a reject and retry response at the target I/O interface for the target with respect to the response from the target, whereby a timeout timer for the command of the initiator is stopped for the queue(s). The outbound logic additionally conducts flow control with respect to the target at the target I/O interface.
