Camunda BPMN Automation

Configuring the Maven in the Eclipse

To use proxy settings in eclipse while using maven, follow these steps:

·         Open your Eclipse and go to Window -> Preferences.

·         Click on the Browse button of User Settings, and select the settings.xml.

Installing the Camunda Archetype

·       For testing we need to add camunda’s maven archetype. For that navigate to https://docs.camunda.org/manual/7.12/user-guide/process-applications/maven-archetypes/

• Add archetype catalog (Preferences -> Maven -> Archetypes -> AddRemoteCatalog): https://app.camunda.com/nexus/content/repositories/camunda-bpm/

Creating Camunda Maven Project

       ·       Create Maven project from archetype (File -> New -> Project..-> Maven -> Maven Project)

     ·       Select camunda-archetype-servlet-war from the catalog that you created before.

         ·       The resulting project look like this , the BPMN files should add into the src/main/resources

           ·       Create the java classes at src/test/java

package explorer of Eclipse 

·       After the Execution the output can be viewed in the target folder.

Example of Bpmn File

• Add TestNG to the project .

sample code:

package com.camunda.camundaDemo;

import static org.assertj.core.api.Assertions.assertThat;

			processInstance.getProcessDefinitionId();
			processInstance.getId();
			// Now: Drive the process by API and assert correct behavior by
			// camunda-bpm-assert
			
			assertThat(processInstance.isEnded()).isTrue();

		}

	

	 @Test
	 @Deployment(resources = { "process.bpmn" })
	public void testNotHappyPath() {
		// ProcessInstance processInstance =

	}

	/***
	 * Fetch the next immediate test from the task service.
	 * 
	 * @param taskService Current Task service.
	 * @return Next Task.

	public Task getNextTask(TaskService taskService) {
