> Hi,
> as already done for the {{KStreamPrintTest}} we could remove the usage of {{KStreamTestDriver}} even in the {{KStreamPeekTest}} and testing it at processor level not at stream level.
> My proposal is to :
> * create the {{KStreamPeek}} instance providing the action which fill a collection as already happens today
> * testing for both {{forwardDownStream}} values true and false
> * using the {{MockProcessorContext}} class for overriding the {{forward}} method filling a streamObserved collection as happens today {{forwardDownStream}} is true; checking that the {{forward}} isn't called when {{forwardDownStream}} is false (so the test fails)
> Thanks,
> Paolo
