Resolution: Fixed
> Need better information about why two object graphs did not compare equal

> Key: JDO-109
> URL: http://issues.apache.org/jira/browse/JDO-109
> Project: JDO
> Type: Improvement
> Components: tck20
> Environment: TCK
> Reporter: Craig Russell
> Assignee: Craig Russell
> Priority: Minor
> Fix For: JDO 2 beta
>
> Need better reporting of deep equality failures.
> During completeness testing, if two object graphs are compared and the result
> is that they are different, there needs to be more information about exactly
> what is different between the object graphs.
> The methods in each class deepCompareFields need to be changed to call into
> the EqualityHelper to do the comparisons and the EqualityHelper can report
> inequalities if the fields don't compare. During the comparison process, all
> fields need to be compared, and the results of compare need to be recorded by
> EqualityHelper. After the comparison of the graph, the collected information
> can be dumped if the results are "not equal".
> New methods in EqualityHelper that take a String tell which fields of which
> class are being compared. Each of the equals(o1, o2) and closeEnough(o1, o2)
> methods need to be expanded to include a third parameter which tells which
> field is being compared. If the result is unequal, then the field information
> is saved in a StringBuffer to be returned if the result of the entire
> comparison is "not equal".
