How to Find NullPointerExceptions for Process Variables During Build Time

Written by Sascha Di Bernardo on , under Community category.
The viadee Process Application Validator (vPAV) was released well over a year ago on GitHub in order to check the interplay of models and code as part of a CI build. Since then vPAV has gained traction and more features were developed. It also provides extensibility to create your own set of checkers. The major release version 3.0.0 comes with many new features, such as a revamped HTML report, inheritance of rules, multiple instantiations of checkers with varying configurations, remote location of process models, multi-language support and most of all a reworked ProcessVariableModelChecker (see release notes).

Process applications basically consist of process model(s) and Java code which both exist side by side and are edited in different tools. For the process models you will most likely use the Camunda Modeler, for the Java code the IDE of your choice. However, no one checks whether model and code are aligned beforehand, e.g. if a bean referenced in a delegate expression actually exists in the code. With the viadee Process Application Validator (vPAV, Open-Source), you can validate your process application regarding these inconsistencies with a simple JUnit test.
