viadee Process Application Validator (vPAV)

The tool checks Camunda projects for consistency and discovers errors in process-driven applications. Called as JUnit test, it discovers esp. inconsistencies of a given BPMN model in the classpath and the sourcecode of an underlying java project, such as a delegate reference to a non-existing java class or a non-existing Spring bean.

A list of the consistency checks can be found here.

To get started with the viadee Process Application Validator read Installation and Usage and Output. We forked the Camunda BPM examples to demonstrate the easy integration of vPAV.

We recommend to integrate the consistency check in your CI builds - you can't find these inconsistencies early enough.

Commitments

This library will remain under an open source licence indefinately.

We follow the semantic versioning scheme (2.0.0).

In the sense of semantic versioning, the resulting XML and JSON outputs are the only public API provided here. We will keep these as stable as possible, in order to enable users to analyse and integrate results into the toolsets of their choice.

Cooperation

Feel free to report issues, questions, ideas or patches. We are looking forward to it.

Licenses

All licenses of reused components can be found on the maven site

Additionally we use the following third-party dependencies, that are not covered via maven-found licences:

• BPMN.io tool under the bpmn.io license.
• Bootstrap licensed under MIT
• jQuery licensed under MIT
• PopperJS licensed under MIT
• Font Awesome licensed under CC, SIL and MIT
• AdminLTE licensed under MIT
• jQuery Knob licensed under MIT
• Bootstrap Table licensed under MIT
• jquery-treegrid licensed under MIT
• FileSaver licensed under MIT
• Start Bootstrap - Simple Sidebar licensed under MIT
• Soot licensed under a LGPL 2.1 license

Soot and bpmn.io provide the basis for the two most exciting features of the validator, i.e. finding inconsistencies in the data and control flow across model and code an the visualization thereof. We would like to explicitly thank these two communities for their continued effort.
