Instance Method Details

#before_starting_agents ⇒ Object

Before DeepTest starts any agents, it instantiates a listener and invokes this method. No other callbacks are made to the listener instance receiving this message.

def before_starting_agents
end

#before_sync ⇒ Object

Before DeepTest synchronizes any code during a distributed run, before_sync is called. If DeepTest is not running distributed, before_sync is never called.

end

#finished_work(agent, work_unit, result) ⇒ Object

Each time a agent finishes computing a result for a work unit, it calls this method before sending that result back to the server. In total, this method will be called as many times as there are work units. The listener instance that received the starting callback with the agent provided here is the same instance that receives this message.

Because each work processes work units in a serial fashion, the listener will receive a starting_work message before another finished_work message.

def finished_work(agent, work_unit, result)
end

#starting(agent) ⇒ Object

A separate listener instance is created in each agent process and notified that the agent is starting. The agent for the process is provided for the listener to use. If you are using 3 agents, this method is invoked 3 times on 3 distinct instances. These instances will also receive the starting_work and finished_work callbacks for the agent provided.

def starting(agent)
end

#starting_work(agent, work_unit) ⇒ Object

Each time a agent takes a work unit, it calls this method before doing the work. In total, this method will be called as many times as there are work units. The listener instance that received the starting callback with the agent provided here is the same instance that receives this message.

Because each work processes work units in a serial fashion, the listener will receive a finished_work message before another starting_work message.
