I have the exact same issue. Not able to get Functional test to run even though application is running fine with its dependencies set up in pom.xml

Simple Maven based App that where NbTestCase case fails when linking org-netbeans-modules-autoupdate-services

As mentioned the HelpSet problem only issues a similar warning. 

The real problem, as mentioned, happens when linking org-netbeans-modules-autoupdate-services into a project which fails the NbTestCase.


I attached a simple example application which fails. Remove the dependency to the included autoupdater module and it works.

Furthermore, I tested the problem with the following dependencies:
- RELEASE73-BETA2
- RELEASE72

Happens to me when I add org-netbeans-modules-xml-tax as well. 
Actually my dependency list is pretty long, but removing these three dependencies will make the Test succeed, while adding them will make it crash (not fail, crash):

Note that the output in my previous comment was seen under MacOS and Java 6.

most likely your compilation classpath is not enough at runtime when running tests. You will need to add test level dependencies.

Thanks for the suggestion. I created a fresh Maven NetBeans Application project and added org-netbeans-modules-db in the app module as a test dependency only ("<scope>test</scope>" in pom.xml)--the error is still the same (including the "The forked VM terminated without saying properly goodbye. VM crash or System.exit called?"). My apologies if I'm doing something wrong here.

the workaround appears to be to add to ApplicationTest.suite():

enableClasspathModules(false). 
clusters(".*").

The workaround worked--thanks!

Hello,

is this class org/netbeans/jellytools/actions/ActionNoBlock on the classpath of the application?

since you have 
enableClasspathModules(false). 
clusters(".*")

turned on in your project, I suspect this issue is different from the one reported originally. I will close this issue as fixed, please create a new issue for your problem. Thanks.
