Hello everyone, I'm working on writing my first trigger and test class and am coming up short on the test class. My trigger is very simple, it takes all of the related Product names from an Opportunity and puts the names in a string on a field on the Opp separated by semicolons:
 

Trigger ProductList on Opportunity (before update, after delete) {

list<opportunity> sl = trigger.new;

list<opportunityLineItem> slnu = new list<opportunityLineItem>([select id ,product2.name, opportunityId from opportunitylineitem where opportunityId =: trigger.new[0].id]);

string productName='';

for(opportunityLineItem opp : slnu){

 productName += opp.product2.name +'; '; // + operator for concatenation.

}

for(Opportunity opp : trigger.new){

 opp.Product_Summary__c = productName;


}


}

Now, below is my test class. Can someone review and tell me what I'm missing here? Thank you.
