When encountering a bug in Activiti, the easiest way to reach the Activiti team and see it fixed is to create an issue in the Activiti Jira (http://jira.codehaus.org/browse/ACT).

Of course, a good description on how to reproduce the problem is crucial. But to make it really interesting for us (and to speed up things), the issue is accompanied by a unit test demonstrating the problem.

To simplify this process, we've created a 'unit test template' project which you can use: https://github.com/Activiti/activiti-unit-test-template
Add your failing unit test, zip up the project and attach it to the issue.

More about this template, read http://www.jorambarrez.be/blog/2012/09/24/how-to-write-a-unit-test/

so good, I will use it to submit bugs.

i'm getting error when i'm running unit test code you provided above.
The error messages:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
i've tried to add config in maven as metioned in userguide.

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-log4j12</artifactId>
  <version>1.7.2</version>
</dependency>

however it does not work.
i've tried to add log4j, common-logging, slf4j jars to classpath and failed too.
can anyone help me? thanks a lot!

It seems that an account on Jira is required in order to submit a bug. How can I obtain it?
When I try to register, the following message is displayed:

"Not a member? To request an account, please contact your JIRA administrators."

But I can't find any administrators address.
Thanks in advance.

In server this process working…

The unit tes here is not a SpringProcessEngineConfiguration, hence why spring beans won't work.

Dear jbarrez,

I download your template from here:https://github.com/Activiti/activiti-unit-test-template/blob/master/src/test/java/org/activiti/MyUnitTest.java

I just modify the location of the process file.

import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;
import org.activiti.engine.test.ActivitiRule;
import org.activiti.engine.test.Deployment;
import org.junit.Rule;
import org.junit.Test;

import static org.junit.Assert.*;

public class UnitTestActiviti{

@Rule
public ActivitiRule activitiRule = new ActivitiRule();

@Test
@Deployment(resources = {"E:/Dropbox/workspaceEclipse/eclipseJuno/customer/addition.bpmn"})
public void test() {
ProcessInstance processInstance = activitiRule.getRuntimeService().startProcessInstanceByKey("Addition process");
assertNotNull(processInstance);

Task task = activitiRule.getTaskService().createTaskQuery().singleResult();
assertEquals("Activiti is awesome!", task.getName());
}

}

Here is the message error I get: java.lang.Exception: Field activitiRule must implement MethodRule

Did you import this as a Maven project? Do you have anything else on your classpath unit test/test related?

I've tried the template and it runs out of the box here. Does the default example process work for you?

I'm trying to use this template in activiti 5.17.0 to examine odd (but consistently reproduceable) behavior in TimerStartEvents. My first issue in doing this is to get the job executor started. The following code fails at the assertion <code>assertTrue(active)</code>, even though my understanding is that the call to <code>setJobExecutorActivate(true)</code> should be starting the jobExecutor for this ProcessEngine instance. What am I doing wrong?
<java>
@Test
public void test() {
ProcessEngine processEngine = activitiRule.getProcessEngine();
processEngine.getProcessEngineConfiguration().setJobExecutorActivate(true);
RepositoryService repositoryService = processEngine.getRepositoryService();
repositoryService.createDeployment()
.addClasspathResource("org/activiti/test/ServiceTaskTimerTest.bpmn")
.deploy();
ProcessInstance processInstance = activitiRule.getRuntimeService().startProcessInstanceByKey("serviceTaskTimerTest");
assertNotNull(processInstance);
boolean active = processEngine.getProcessEngineConfiguration().getJobExecutor().isActive();
assertTrue(active);
// Other stuff…
</java>

Hi Mark,

have a look on

org.activiti.engine.impl.test.JobTestHelper#waitForJobExecutorOnCondition(org.activiti.engine.ProcessEngineConfiguration, long, long, java.util.concurrent.Callable<java.lang.Boolean>)

in the activiti source
You can see there how to start jobExecutor.

Martin

Thank you, Martin, this solved the problem. For those who may be interested, the relevant code to kick off the JobExecutor (class org.activiti.engine.impl.jobexecutor.JobExecutor) for a unit test looks like this:
<java>
//
// Use one of the many ways to construct an org.activiti.engine.ProcessEngine object.
//
JobExecutor jobExecutor = processEngine.getProcessEngineConfiguration().getJobExecutor();
jobExecutor.start();
</java>

Hi jbarrez,

I received issue "Caused by: org.h2.jdbc.JdbcSQLException: Table "ACT_HI_PROCINST" already exists; SQL statement:" when I use the given junit template. May I know how to clean h2 before test?

In addition, I would like to know how to let activitirule to load configuration spring.
