Subject [jira] Commented: (JDO-432) Test for behaviour of null passed to detachCopy(), makePersistent(), etc
Date Mon, 16 Oct 2006 21:35:35 GMT
    [ http://issues.apache.org/jira/browse/JDO-432?page=comments#action_12442711 ] 
Craig Russell commented on JDO-432:

Looks good; just a few comments.

1. The Assertion Description section of javadoc exceeds 80 characters in most of the tests.
Perhaps the description could be abstracted to the superclass and reduced to 80 character
lines, and then the description in the subclass would reference the superclass and name the
method, e.g. "Test null arguments for makePersistent."

2. Javadoc for checkReturn methods (both Collection and Object[ ]) is incorrect. It only checks
that corresponding parameters are either null or not null.

+    /**
+      * Checks if expected and actual arguments are equal
+      * @return true if arguments are equal
+      * @param expected Collection
+      * @param actual Collection
+      */
+    protected boolean checkReturn(Collection expected, Collection actual) {
+            if ( (eElem == null && aElem != null)
+               || (aElem == null && eElem != null) )
+                return false;

3. The method makeTestInstancesPersistent should only make the instance persistent, and not
use makePersistentAll methods, since these methods are supposed to be tested with these test

4. Consider putting getPM() into the makeTestInstancesPersistent method instead of in localSetUp.
Consider getting rid of makeTestInstancesPersistent entirely and putting all the logic into
localSetUp, its only use.

> The JDO2 spec adequately defines (section 12.6.0 "Null Management")  behaviour when null
values are passed in to the PersistenceManager methods makePersistent, detachCopy, etc but
there doesnt seem to be a test for these situations currently. JPOX 1.1.2 on calling detachCopy(null)
actually throws an NPE, which is outside of spec ... now fixed.
