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

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.shTests all the test programs in a loop. Outputs the number of test cases run and the result of the testing.

compare_java.shHelper script called by test_script.sh which does actual part of comparing the two java   programs using the diff command.

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.
