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 cases.

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.
