I need help with a Delete Trigger Test

I have a delete trigger to stop deletion when certain conditions are true. The trigger is working fine. I've tested it in the sandbox. The test however is giving me some problems. I have looked in the community and used some of the suggestions given, however I haven't been able to make it work.

Here is my trigger & test

trigger whenCampaignDeleted on Campaign (before delete) {
    List<Campaign> delCampaign = trigger.old;
    Boolean dontDelete = False;
    Boolean relCampaign = False;
    for (Campaign eachCampaign : delCampaign)
    {
        //If the campaign is Adventure type check to see if there are campaign members
        //with status "Attended" and if there is a related campaign: volunteer campaign
        If (eachCampaign.RecordTypeId == '012o0000000xwhO')
        {
               If (eachCampaign.Related_Campaign__c != NULL)
                 relCampaign = True;     
            List<CampaignMember> cMs = [SELECT id, status FROM CampaignMember
                               WHERE CampaignId = :eachCampaign.Id];
 
            For (CampaignMember eachCM : cMS)
            {
                 If (eachCM.Status == 'Attended')
                {dontDelete = True;}
            }
            If (dontDelete)
                eachCampaign.adderror('Cannot delete a campaign that has members with status Attended. Their status must be changed first.');
            If (relCampaign)
                eachCampaign.adderror('Before deleting the campaign you must delete the volunteer campaign associated with it.');
        }
        Else 
        //If the campaign is a volunteer campaign then retreive the Adventure campaign related to it
        //and delete the related campaign from the Adventure record
        If (eachCampaign.RecordTypeId == '012o0000001AJaa')
        {
            if (eachCampaign.Related_Campaign__c != NULL)
            {
                Campaign relCampRecord = [SELECT ID, Related_Campaign__c FROM Campaign 
                                         WHERE Id = :eachCampaign.Related_Campaign__c];
                relCampRecord.Related_Campaign__c = NULL;
                Update relCampRecord;
            }
        }
    }
}



——————  Test
After inserting a few records to test the trigger the following code performs the test (here I am just testing it with one record to single out the error, but it is set up to test a list of records).


        try
        {
            delete myCampaigns[1];
            System.assert(false);
        }
        catch (DMLException e)
        {
            // Check that the trigger interrupts the deletion
            system.assertEquals('Before deleting the campaign you must delete the volunteer campaign associated with it.', e.getMessage());
        }





When I run the test I get the following error

System.AssertException: Assertion Failed: Expected: Before deleting the campaign you must delete the volunteer campaign associated with it., Actual: Delete failed. First exception on row 0 with id 701n0000000DlUDAA0; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, Before deleting the campaign you must delete the volunteer campaign associated with it.: []



Can any one help? I am not sure how to change the System.assert to verify that the deletion is not done.

Thanks in advance for any help

            System.assert(false);
        }
        catch (DMLException e)
        {
                 Boolean expectedExceptionThrown =  e.getMessage().contains('Before deleting the campaign you must delete the volunteer campaign associated with ')) ? true : false;
                System.AssertEquals(expectedExceptionThrown, true);

        }
