5.0.beta1 Activiti Examples (Test Cases) FAILED in Grails

limcheekin — Sat, 04 Sep 2010 02:42:32 GMT

Hi,Majority of the Activiti Examples Test Cases FAILED due to error NullPointerException for runtimeService variable in Grails environment. But this problem only happened in Activiti 5.0.beta1 not 5.0.alpha4 (All tests PASSED). Currently, this issue is blocking the release of Grails Activiti Plugin

It seems like the processEngine variable not initiated properly in ProcessEngineTestCase super class related to loading of activiti.properties file. It is obvious to me that it is environment issue. But I not sure how to fix it. Anyone here have any clue how to solve this problem?

Do you have more information on what the exact cause is? The Activiti test suite also uses ProcessEngineTestCase.processengine and there it works. Ideally we would be able to build a GrailsTest in our test suite that guards how you use Activiti APIs. That way we know when we break your use case. I don't have time to reproduce the grails tests.

The process engine is built during the runBare() of the ProcessEngineTestCase. Could you verify if this method is actually called?

Hi,

Thanks for fast and helpful response. Yes, it is confirmed that the runBare() of the ProcessEngineTestCase is NOT called by Grails Test Environment. Unluckily, Grails Developer have decided not to fix this issue, you can find out more here at http://jira.codehaus.org/browse/GRAILS-6002.

Is it possible to use the work around @Rule annotations as mentioned in the jira issue?

That explains your errors …

I assume you could work around this, but only if you would introduce your own superclass with a Rule and change all the tests to have it as a parent…

Thanks. I think I will remove it for Grails Activiti Plugin 5.0.beta1 release as I don't have time to fix it now and I don't have any knowledge on @Rule annotation. May I know anyone here volunteer to fix this issue? I welcome you to join Grails Activiti Plugin project at http://code.google.com/p/grails-activiti-plugin/

As I understand correctly, runBare() was widely used in jUnit3 and not anymore in jUnit4?
If that is the case, should the Activiti developers do something here to make Activiti more compatible with jUnit4?

Richard, I've created a JUnit3-style test case and a JUnit4 style rule as part of the public packages. HTH

Hi Tom,

Thanks. Look forward the release of Activiti 5.0.beta2 and incorporate this feature to the Grails Activiti Plugin.

Hi Tom and Joram,

As per beta2 release, the examples still using JUnit 3 style of testing, for example:


public class CallActivityTest extends ActivitiInternalTestCase {
…….

May I know is there any plan to upgrade it to JUnit 4 as documented at http://activiti.org/userguide/index.html#apiUnitTesting?

Afaik not, the Junit 4 support is there for our end users.
However, for the Grails plugin, is the only consequence that the out-of-the-box tests can't be run? Or is there something else ?

Yes, the only consequence is most out-of-the-box tests failed to run. But I think to run the out-of-the-box tests successfully is important to ensure that nothing is broken for Activiti (based on test cases) in Grails environment. Also, the test cases is important source for developers to learn about Activiti. So, will you re-considered to support JUnit 4?

Wish to hear from you soon!

Fyi, I am migrating all example test cases to JUnit4 style for the grails plugin by writing a script to do the migration.
