Test Interference can be also used in scripted test cases, by scripter commands. New keyword, testinterference is used for that. Starting interference is done in the following way:
testinterference name command type value idle_time busy_time
testinterference - mandatory keyword
name - identifier of created testinterference
command - can have two values, "start" or "stop"
type - can have the following values: "cpuload", "memload" and "ioload". Determines type of started interference.
value - numeric parameter, for cpuload determines amount of taken CPU time in percent. For memload it holds amount of taken memory in megabytes. For ioload value is ignored.
idle_time - numeric parameter, specifies time in cycle when disturbance is stopped (in milliseconds). Giving it value 0 is equal to starting constant disturbance.
busy_time - numeric parameter, time the disturbance is active during cycle.
All numeric parameters are mandatory ( due to way parameters are handled in scripter).
Failure to call "stop" command for all "started" interferences in test case will make the case invalid.
