All, Just wanted to let you know that my NiFi Script Tester has been updated, turned out the original version didn't work so well :-P
I've fixed the bugs I found and added some helpful things (such as Apache Commons IO to the fat JAR, for IOUtils.toString()) and the "-module" option to add module paths like you would set in the Module Directory property in the ExecuteScript processor. Also I finally got around to writing a blog post about it: http://funnifi.blogspot.com/2016/06/testing-executescript-processor-scripts.html If you use it, please let me know how/if it works for you :) Regards, Matt
