Hi,

I am new to APEX development and have been trying every idea I can find from these forums to make this visualforce controller pass the test threshold. 

The controller simply holds values for contact information entered in a visual force page, creating a new row for each new entry, and then inserting all entries when done. 

I have gotten it up to 72% in testing. But without being able to add a contact Last Name i get the error "System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [LastName]: [LastName]"

On the other hand most attempts I have made to add a contact last name have not validated, producing a complie error, "Initial term of field expression must be a concrete SObject: LIST<Contact> at line 35 column 3."

Apex Code and TestMethod

public class multiContactInsert{

    public List<Contact> cont {get; set;}
    
    public multiContactInsert(){
        cont = new List<Contact>();
        cont.add(new Contact());
    }
    
    public void addrow(){
        cont.add(new Contact());
    }
    
    public PageReference save(){
        insert cont;
        PageReference home = new PageReference('/003?fcf=00B800000081Zoh');
        home.setRedirect(true);
        return home;
    }

///////////////////////
///TEST METHOD
//////////////////////


static testMethod void test()
{
  
  PageReference pageRef = Page.multiContactadd;
  Test.setCurrentPage(pageRef);

  multiContactInsert controller = new multiContactInsert();
  controller = new multiContactInsert();
  
  //controller.cont.LastName = 'Smith';
  // Not able to add lastname
  
  controller.addrow();

  controller.save();
}  



}

Here is the VisualForce page for reference.
