camunda bpmn testing without spring ?

[nds.t...@gmail.com]

Hi,

I try to test my bpmn diagram, and i've find this example:
--
https://github.com/camunda/camunda-bpm-examples/blob/master/bpmn-model-api/generate-process-fluent-api/src/test/java/org/camunda/bpm/quickstart/CreateInvoiceProcessTest.java
--

but i can't instantiate ProcessEngineRule :

public ProcessEngineRule processEngine = new ProcessEngineRule();

this throw a message :
------------------------
org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions
Infos: Loading XML bean definitions from class path resource [activiti.cfg.xml]

I don't use spring, just the standalone camunda version, so i don't have camunda.cfg.xml file in /ressources.

How to test my camunda bpmn diagram without spring ?

[Sebastian Menski]

Hi,

what do you mean with test the BPMN diagram? You don't need spring, the camunda bpm

platform uses spring to bootstrap. That's why it searches for a camunda.cfg.xml.

If you want to write unit tests for your process execution have a look at your

simple unit test template.

If you can describe your use case more I think we can help you better.

Cheers,

Sebastian

Hi Sebastian, 
I am having the same problem. My question is that why is it looking for activiti.cfg.xml? 

Oct 21, 2014 3:53:14 PM org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions

INFO: Loading XML bean definitions from class path resource [camunda.cfg.xml]

Oct 21, 2014 3:53:14 PM org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions

INFO: Loading XML bean definitions from class path resource [activiti.cfg.xml]

While it seems to work fine looking for camunda.cfg.xml, but activiti,cfg,xml????

I wrote a unit test for the example: Getting Started with camunda BPM and the Spring Framework

https://github.com/camunda/camunda-get-started-spring

Unit test: 

package org.camunda.bpm.getstarted.loanapproval;

import static org.camunda.bpm.engine.test.assertions.ProcessEngineTests.runtimeService;

import org.camunda.bpm.engine.runtime.ProcessInstance;

import org.camunda.bpm.engine.test.Deployment;

import org.camunda.bpm.engine.test.ProcessEngineRule;

import org.junit.Rule;

import org.junit.Test;

public class UnitTest {

    @Rule

    public ProcessEngineRule processEngineRule = new ProcessEngineRule();

    @Test

    @Deployment(resources = {"loanApproval.bpmn"})

    public void testTestTest() {

        ProcessInstance processInstance = runtimeService().startProcessInstanceByKey("loanApproval");

        System.out.println(processInstance.getProcessDefinitionId());

    }

}

I even added the camunda.cfg.xml file from your example. And it keep failing because it fails to find the activiti.cfg,xml. 

Cheers, 

Tina

Hi Tina,

The junit rule is falling back to activiti.cfg.xml because it did not find camunda.cfg.xml in the classpath. It is a backward compatibility step when we forked form activiti to ease the migration from activiti to camunda bpm.

Anyway, you can also create the process engine programmatically without a camunda.cfg.xml.

protected ProcessEngine createProcessEngineProgramatically() {

  StandaloneInMemProcessEngineConfiguration processEngineConfiguration = new StandaloneInMemProcessEngineConfiguration();

  processEngineConfiguration.setCustomPostBPMNParseListeners(Arrays.asList(new BpmnParseListener[]{new FoxFailedJobParseListener()}));

  return processEngineConfiguration.buildProcessEngine();

}

@Rule

public ProcessEngineRule rule = new ProcessEngineRule(createProcessEngineProgramatically());

Cheers,

Christian
