Subject [jira] Commented: (JDO-582) Test case needed for JDOFatalUserException nested exception argument needs cast to Throwable[]
Date Fri, 12 Sep 2008 00:13:44 GMT

    [ https://issues.apache.org/jira/browse/JDO-582?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12630431#action_12630431

Craig Russell commented on JDO-582:

In the JDOHelperConfigTest, I don't think you're testing the error condition. What JDOHelper
is doing is iterating over the services entries and finding classes to load. So there is a
need for Negative09/09a/META-INF/services that contains a bad class and another Negative09/09b/META-INF/services
that contains another bad class.

I'd suggest using two of the bad classes from JDOHelperTest (except that these are private).
I've checked in a patch to JDOHelperTest that makes the inner classes public so they can be
referenced outside the test class. 

Then the services/javax.jdo.PersistenceManagerHelper files can have one-liners: javax.jdo.JDOHelper$BadPMFNoGetPMFMethod
and javax.jdo.JDOHelper$BadPMFNonStaticGetPMFMethod. 

And the test should test that the nestedThrowable array contains two elements.

> After collecting exceptions from invoking getPersistenceManagerFactory on all implementations,
if no implementation has succeeded in returning a PersistenceManagerFactory, an exception
is thrown, and the argument should be a Throwable[]. Otherwise, it's treated as a failed object
instead of nested exceptions.
