Hello,

I've been working on trying to create the test class for the below trigger, but I keep getting an error that I have 0% test coverage. Is there a reason that my Test Class is not covering my Trigger? If someone can please help me with this, I would greatly appreciate it - I've been wrestling with it for a few hours to no avail.

Thank you!!

Trigger (it is updating a field on the Opportunity based on a field from a custom child object):

trigger Update_SE_NHC_Assignment_Final on Network_Health_Check__c (before insert, after update) {

//Set the Opportunities to Update
Set<Id> OpportunityforUpdate = new Set<Id>();
    
  //When adding a new Network Health Check or Updating an existing Network Health Check
  if(trigger.isInsert || trigger.isUpdate || trigger.isDelete ){
for(Network_Health_Check__c n: [Select Related_Opportunity__r.id, Assigned_SE__r.id from Network_Health_Check__c]) {
    OpportunityforUpdate.add(n.Related_Opportunity__r.id);
 
  List<Opportunity> OpportunitiesToUpdate = new List <Opportunity>();
 
  //Update the SE NHC Assignment field on the related Opportunity to match the SE Assigned field on the Network Health Check Object
  for(Opportunity o : [Select Id, SE_NHC_Assignment__c from Opportunity where Id IN :OpportunityforUpdate]){
    o.SE_NHC_Assignment__c = n.Assigned_SE__r.id;
    OpportunitiesToUpdate.add(o);
  }
 
  update OpportunitiesToUpdate;
}
}
}

Test Class:

            System.debug('we caught a dml exception: ' + e.getDmlMessage(0));
