Need to simulate workflows of complex processes This stuff can get complex !!  No kidding !

Need to simulate workflows of complex processes Need to KISS !! (Keep It Simple Silly) A means to analyze and produce statistical results

A language designed to handle workflows in industries Java-like syntax Aimed at easier design, simulation and analysis of workflows

Use JVM on user’s environment Makefile! translate wowcompile wowrun Runtime script executes the Parser on the WoW program./wow WoWPrograms/Audi.WoW

Testing of the WoW compiler is done by comparing the translated Java code of a WoW program with the expected Java code. Ideally translation should fail if there are compilation errors in WoW program. If mismatch between translated java and expected java then test case fails.

test_script.sh Tests all the test programs in a loop. Outputs the number of test cases run and the result of the testing. compare_java.sh Helper script called by test_script.sh which does actual part of comparing the two java programs using the diff command.

#!/bin/bash java_count=0 total_java=0 for D in `find Test -type d` do if [ "${D}" != "Test" ] then name=$(basename ${D}) java_test=$(./compare_java.sh $name) if [[ "$java_test" == *passed* ]] then java_count=`expr $java_count + 1` fi echo $java_test total_java=`expr $total_java + 1` fi done echo "$java_count of $total_java Java tests passed”

#!/bin/sh if diff -w -E -b -B "Test/$1/Translated.java" "Test/$1/ExpectedJava.java" >/dev/null ; then echo $1 Java test passed! else echo $1 Java test failed! fi

The test results shown in the previous slides where obtained at 100% pass rate after multiple testing iterations. There were few bugs in parsing and translating which where caught during testing.

“ IBM project management better, but not applicable” - Amol Joshi (System Integrator) “The time spent upfront to make regression tests is worth the effort” – Chaitanya Korgaonkar (Verifier and Validator) “Collaborative programming is not difficult if every member of the team is informed about the architecture” – Dharmen Mehta(Program Manager) “Done is better than perfect! Do not waste excess time on finer details” – Nimai Buch(Language Guru) “Take your time to build a good architecture, but make sure it is close to perfect when you’re done.” – Yash Parikh (System Architect)
