#Streams to assist testing Streams
writing streams can be difficult, one of the most difficult aspects can be testing them thoroughly.
that is where stream-tester comes in. stream-tester can be used to generate data to exercise your streams. combine it with stream-spec which will validate your stream's behaviour and you've got a pretty easy test suite.
create a stream of random chunks. generator defaults to Math.random.
emit 'end' after max chunks. max defaults to Infinity
create a stream of increasing numbers, up to max
create a through stream that randomly pauses
(returns false from write). prob is the probability
of a pause. delay is the time to wait before emitting 'drain'. defaults are prob=0.1, and delay is next tick.
