Greetings,

I'm pulling my hair out trying to find out why my test method is failing.

I've "borrowed liberally" from Colin Loretz's page on creating rollup fields between any object, (x-ref http://colinloretz.com/tag/salesforce-apex-code/).

The trigger I've created aggregates values from "child" records, placing the total value on the parent.  Works great.

The test method however, fails on the assertequals clause :

...

    // Test ParentObj__c "p" created, which automatically spawns the

    // creation of a default first ChildObj__c with a Percent__c equal to 100.

...

    List<ChildObj__c> ChildObjList = new List<ChildObj__c>();
    ChildObj__c c1 = new ChildObj__c(ParentObj__c=p.id,Percent__c=10);
    ChildObj__c c2 = new ChildObj__c(ParentObj__c=p.id,Percent__c=25);
    ChildObj__c c3 = new ChildObj__c(ParentObj__c=p.id,Percent__c=50);

    ChildObjList.add(c1);
    ChildObjList.add(c2);
    ChildObjList.add(c3);

    //Insertion test 100 + 10 + 25 + 50 = 185
    {
        insert ChildObjList;
        p = [select id, Total_Percent__c from ParentObj__c where id=:p.Id];
        System.assertEquals(185,Parent.Total_Percent__c);

        // "System.AssertException: Assertion Failed: Expected: 185, Actual: 555" ?!?!?!

    }

...

If I set my "expected" value to 555, then continue with update and deletion tests, things seem to normalize.  I noticed that the "Actual Result" is always three times the expected, (because I'm inserting three records).  If I only do two inserts, then the delta is off by two times the expected, (and I can avoid the issue entirely if I do a single record test, but I'd really like to understand why this is happening).

Thanks for any insight,

Pete
