[Resolved] JUnit tests not working, but process working in Activiti-Explorer

Hello,

Since some weeks ago, I had to format my computer, so everything I had installed for Activiti and all the configurations were gone. I took me time to make everything work again, but now it does. Back then I asked about a problem I was having with Activity Explorer. Summarizing, I had JUnit tests that were working when using Spring + JPA + Activiti, but Activiti-Explorer stopped working if I wanted to use the designed workflow process. Now it's exactly the opposite: it works on Activiti-Explorer, but it doesn't in a test. I've searched all these forums and most of useful links on Google, but nothing seems to work. Here you have my code, maybe you can help me.

Also note that I have two different (but probably related) problems: variables seem not to be stored in the process (I even tried to add them manually by using setVariable (
ts.setVariable(task.getId(), sellerVar, userAssignee);‍
), so it doesn't find them afterwards in other tasks of the same process, but they don't have any problem using explorer and they were stored back then with my other configuration. Also, it's not detecting my user form type classes, but I have 
activiti-explorer-5.14.jar‍
in my classpath (I can find both formtype and renderer in the package explorer of Eclipse).

I'm probably having a basic mistake, but I've been for too much time trying to fix this and testing things with no success and I don't know where to continue. Somebody may be in the same situation as me, or have encountered something similar, and can be easily fixable. Also, next time people can save time with similar problems if it's something very simple. Thanks a lot for your help.



Kind regards.

Also, I did not find any unit test for a slightly complex workflow which implies the use of several different tasks, variable access and forms. Where could I find something like this? Thanks again.

It's pretty easy actually: you fetch and complete a task:

<code>
Task task = ts.createTaskQuery().singleResult();

  assertNotNull(task);
  assertNotNull(task.getAssignee());
  assertEquals(task.getAssignee(), userAssignee);

  ts.complete(task.getId());
  ts.setVariable(task.getId(), sellerVar, userAssignee);
</code>

The sequence flow goes to the exclusive gateway:

<code>
    <sequenceFlow id="flow3" sourceRef="selectCustomerMethod" targetRef="exclusivegateway1"></sequenceFlow>
</code>

The outgoing sequence flow out of the gateway use the variable:

<code>
     <sequenceFlow id="flow4" sourceRef="exclusivegateway1" targetRef="customerCreation">
        <conditionExpression xsi:type="tFormalExpression"><![CDATA[${isCustomerCreated == 'true'}]]></conditionExpression>
      </sequenceFlow>
</code>

HOWEVER, it is only LATER in the test you add the 'isCustomerCreated' variable. So the error is correct, the variable was never passed into the engine at that point.

It was very easy indeed. I just did not realize about it, but it's working fine right now. Thanks a lot for your time.

PS: A "resolved" tag in each title thread would be awesome. Could you edit my first post? Thanks again.
