camunda engine unit test template to reproduce a problem

This git repository contains a simple example of how to reproduce the problem in "NPE with Process Test Coverage and Link Events" in Camunda forum

The project contains the following files:

src/
└── test
    ├── java
    │   └── org
    │       └── camunda
    │           └── bpm
    │               └── unittest
    │                   └── SimpleTestCase.java   (1)
    └── resources
        ├── camunda.cfg.xml                       (2)
        └── testProcess.bpmn                      (3)

Explanation:

• (1) A java class containing a JUnit Test. It uses the ProcessEngineRule for bootstrapping the process engine, as well as camunda-bpm-assert to make your test life easier.
• (2) Configuration file for the process engine with the ProcessCoverageInMemProcessEngineConfiguration.
• (3) The BPMN process with a link event.

Running the test with maven

In order to run the testsuite with maven you can say:

mvn clean test

Verifying that the problem lies in the test coverage

Simply edit the camunda.cfg.xml and use the StandaloneInMemProcessEngineConfiguration instead. The test runs fine then.
