BPMN Project Structure
=======================
BPMN main process flow
----------------------
A BPMN main process flow is a top-level flow. All main process flows are under the src/main/resources/process folder.
CreateVfModuleVolumeInfraV1 is a main process flow.

Open BPMN files with the camunda modeler (standalone application). To launch the modeler from eclipse, right-click→open-with→Other→Browse. Select Check the boxes on the dialog so that eclipse will open all .bpmn files with the camunda-modeler executable.
BPMN subprocess flow
---------------------
A BPMN subprocess flow is meant to be invoked by other flows (either main process flows or other subprocess flows). All subprocess flows are under the src/main/resources/subprocess folder.
The CreateVfModuleVolumeInfraV1 process flow is delivered with two custom subflows: DoCreateVfModuleVolumeV2 and DoCreateVfModuleVolumeRollback.

Groovy scripts
---------------
There is one groovy script for each BPMN file. Groovy scripts are invoked by script tasks within the BPMN flows.

Unit Tests
-----------
Normally, we create a unit test class for every flow. This one is missing a unit test for its rollback flow.

Unit Test Resource Files
------------------------
Any files needed by the unit tests are kept under the src/test/resources/__files folder.
