13 Activiti 5.0.rc1 JUnit4 Test Cases FAILED in Grails

[limcheekin]

Hi there,

I am ported the Activiti examples to JUnit4 styles, but 13 test cases are FAILED.

Given activiti.cfg.xml file:
<activiti-cfg process-engine-name='activiti-engine-test'>
  <database type='h2' schema-strategy='create-if-necessary'>
    <jdbc url='jdbc:h2:mem:activiti;DB_CLOSE_DELAY=1000' driver='org.h2.Driver' username='sa' password='' />
  </database>
  <job-executor activate='false' />
  <mail server='localhost' port='5025' default-from='username@yourserver.com' />
</activiti-cfg>

Attached here is the test-reports and source code of the test cases for your reference:

Any ideas why the 13 tests failed?

Looks like a classloading problem. Is there anything special classloading going on the grails environment ?

[limcheekin]

Yes. But it is not specific to Grails environment, it is more on Groovy environment.

When you continue look down to the stack trace, you can see org.codehaus.groovy.tools.RootLoader. It is special classloader of Groovy.

Ok, that could explain it.

But we have more tests that use a pojo that is in the src/main/resource/org/activiti/… package. Why isnt this class found ?

Yes, I doubt on that also.

I found this topic for following Exception:

ActivitiException: coudn't deserialize object in variable

and solved the problem adding "implements Serializable" and the the field "private static final long serialVersionUID = 1L;" to the class.

[limcheekin]

Great! Thanks for solution provided. I will try it out.

Hi there,

The activiti plugin 5.7 has the same error even existing POJO class implemented the solution you mentioned, you can try out the latest plugin released few days ago.

Seems like a classloading issue to me (see the ClassNotFoundException), did you add the pojo to the test runner classpath?

[limcheekin]

Hi Joram,

Thanks for response.

The POJO located in same directory as per the test cases. But I not sure I missed anything unknown to me.
