[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.

I still don't use the entity Client nor its service ClientService, since first I'm trying to run a basic example.

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.
