Aloha,

I'm having trouble testing out this line of code:

    public List<Order_Dimension__c> getdimList() {
            return dimList;
      }

Below is the full controller and test method so far, but only 60% is covered and the lines above are marked in red as not being tested.

public with sharing class OrderExtension{
    
    
    private final List<Order_Dimension__c> dimList;
    
    public OrderExtension(ApexPages.StandardController controller)     
        {
        dimList = [select e.Name, e.Commodity_Description__c, e.Length_Feet__c, Length_Inches__c, Width_Feet__c, Width_Inches__c, Height_Feet__c, Height_Inches__c, Classification__c, Dimensions__c
        from Order_Dimension__c e where Order__c=:ApexPages.currentPage().getParameters().get('id') 
        ];
    }
        
    public List<Order_Dimension__c> getdimList() {
            return dimList;
      }
  
}
