Test Class for pagination

Hi folks,
      Can anyone tell me how to write the test class for pagination?
Below is my test class which covers 85%  but it didnt covers the hasnext,previous and pagenumber method.
  
@isTest(SeeAllData=true)
public class PaginationControllerTest {
    
        public static testMethod void testSearchAccount() {
        PageReference pageRef = Page.TestPagination;
        Test.setCurrentPage(pageRef);

        // Instantiate a new controller with all parameters in the page
    
        PaginationController  p=new PaginationController ();
        
        p.getAccountList();
        p.Next();
        p.First();
        p.Last();
        p.Previous();
        p.Cancel();
        p.con.getHasPrevious();
        p.con.getHasNext();
        p.con.getPageNumber();
        
       
     }

}



Controller: 
public class PaginationController {
    public ApexPages.StandardSetController con {
        get {
                if(con == null) {
                    con = new ApexPages.StandardSetController(Database.getQueryLocator([Select Id, Name,Type FROM Account])); 
                    con.setPageSize(5);                      
                }
                return con;
        }
        set;
    }
    
    public List<Account> getAccountList(){
        return (List<Account>)con.getRecords();
    }
    
    public Boolean hasNext {
        get {
                return con.getHasNext();
            }
        set;
    }
   
    public Boolean hasPrevious {
        get {
            return con.getHasPrevious();
        }
        set;
    }
   
    public Integer pageNumber {
        get {
            return con.getPageNumber();
        }
        set;
    }
   
    public void first() {
        con.first();
    }
   
    public void last() {
        con.last();
    }

    public void previous() {
        con.previous();
    }
    
    public void next() {
        con.next();
    }
  
    public void cancel() {
        con.cancel();
    }        

}


Thanks in advance

Dear Patrik

I tried your code, the run test failed, although it raised my code coverage from 19% to 34%
  
@isTest  (SeeAllData=true) 

    private class TESTAccountOpportunityTabExtension {
