Maybe the statement could be a bit hyperbolic, but it could be tested. I tested large complex flows locally, 59 steps, within JUnit. These test ran with every build. So the whole build took 6 minutes for 75 fraud models, but I cold easily focus on just my unit in Eclipse.<p>I haven&#x27;t tried PigUnit for a while, but last time I did, it didn&#x27;t support macros and took minutes for how has would take seconds in Cascading.<p>It&#x27;s this difference that&#x27;s cemented in my mind that Cascading is for repeatable processes while Pig is for probe ring and experimentation. This is not to say you can&#x27;t reuse Pig scripts. I mean that I have greater confidence in the things I can create repeated tests for.
