I've got a number of lookup fields that I need to populate based on an ID field that will be passed over from our source system. The custom object is Agent__c.I've been able to get to 83% coverage (which I know is fine - but we're going to have hundreds of leads processing via this every day - and I want to make sure it won't fail).Any help/advice would be hugely appreciated.Here's my trigger:trigger AgentAssignmentLead on Lead (before insert, before update) { Set <String> AgentIDs = new Set <String>(); for (Lead l : trigger.new) { if (l.Agent_ID__c !=NULL) { AgentIDs.add (l.Agent_ID__c ); } }//now we have our list of agent IDs that we want to check against.//We will build a map of the "match" field Map<String, Agent__c> Agents = new map <String, Agent__C>(); for (Agent__c obj: [SELECT ID, Agent_ID__c from Agent__c Where Agent_ID__C in :AgentIDs]){ Agents.put(obj.Agent_ID__c, obj); } for (Lead l : trigger.new) { if (l.Agent_ID__c !=NULL){ if (Agents.containsKey(l.Agent_ID__c)) l.Agent__c=Agents.get(l.Agent_ID__c).ID; } }}And my test class:@istestpublic with sharing class AgentLeadTest { public static void UpdateAgent() { //create the new lead Lead Lead = new Lead (); Lead.LastName='Adrian'; Lead.FirstName='Tooms'; Lead.status='Unread'; Lead.Metro__c='New Jersey'; Lead.Agent_ID__c='100683628'; test.startTest(); insert Lead; }}
