Component ProcessServiceSession is used from PUnitSuite test cases to exercise the Process under test.
This component provides methods to perform several operations on the process, including: creating new process instances, executing activities, aborting instances, adding notes, sending notifications, (un)grabbing instances and (un)selecting instances.
The ProcessServiceSession component must be used in the context of a PUnit component. After calling PUnitSuite.createSession(), an instance of ProcessServiceSession is available from the PUnitSuite.session attribute.
Refer to Oracle BPM Studio Help for details on how to create unit tests and PUnit test cases.
