Hi

I have to increase the coverage for below class:

public with sharing class ContactPortalUserController
{
    List<User>luser  = new List<User>();
    List<contact>selectedCon = new List<contact>();
    ID profileID = [select id from profile where name = 'High Volume Customer Portal'].id;
    private ApexPages.StandardSetController standardController;
   // ApexPages.Message myMsg = new ApexPages.Message('info', summary);
    public ContactPortalUserController(ApexPages.StandardSetController standardController)
    {
        this.standardController = standardController;
          }

     public PageReference selectedContact(){
     List<Contact>selectedContact = (List<Contact>) standardController.getSelected();
    system.debug('****1***'+selectedContact );
     selectedCon = [select id , name , firstname, email ,EmailEncoding__c,LanguageLocaleKey__c,TimeZoneSidKey__c,LocaleSidKey__c, lastname from contact where id in:selectedContact];
     system.debug('***21***'+selectedCon );
     for(contact con:selectedCon)
     {
      User us = new User();
      us.alias  =   con.Firstname.substring(0,3) +'cus';
      us.email  =  con.email;
      us.emailencodingkey= con.EmailEncoding__c;
      us.lastname = con.lastname;
      us.languagelocalekey = con.LanguageLocaleKey__c;
      us.localesidkey =con.LocaleSidKey__c;
      us.profileid = profileID;
      us.contactId = con.id;
       us.timezonesidkey = con.TimeZoneSidKey__c;
       us.username =  con.email +'cus';
       luser.add(us);
     
     }
    
    try{
     
     insert luser;
     ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.Info, 'Users have been inserted successfully.');
    ApexPages.addmessage(myMsg);
     
     // myMsg = ;
                  //ApexPages.addMessage(myMsg);   
     
     }
     catch(exception e)
     {
       e.getmessage();
        ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR,'Error Occured while inserting users,' + e.getmessage());
                  ApexPages.addMessage(myMsg);   
     }
   
     return null;
     }

    
}

Highlighted lines are not getting covered.

Test class:

public class  ContactPortalUserControllerTest{

    public static testMethod void testContactPortalUserController() {
      Profile p = [SELECT Id FROM Profile WHERE Name='System Administrator'];
      User u = new User(Alias = 'standt', Email='standarduser@testorg.com',
      EmailEncodingKey='UTF-8', LastName='Testing', LanguageLocaleKey='en_US',
      LocaleSidKey='en_US', ProfileId = p.Id,
      TimeZoneSidKey='America/Los_Angeles', UserName='standarduser1112@testorg.com');


      System.runAs(u) {
    ID profileID = [select id from profile where name = 'High Volume Customer Portal'].id;

    List<contact> lcontact = new List<contact>();
    Contact con = new contact();
    con.lastname = 'test';
    con.email = 'Test@accenture.com';
    con.LanguageLocaleKey__c =  'en_US';
    con.LocaleSidKey__c = 'en_US';
    con.EmailEncoding__c = 'UTF-8';
    con.TimeZoneSidKey__c = 'America/Los_Angeles';
    insert con;
     Contact con1 = new contact();
    con1.lastname = 'test1';
    con1.email = 'Test@accenture.com';
    con1.LanguageLocaleKey__c =  'en_US';
    con1.LocaleSidKey__c = 'en_US';
    con1.EmailEncoding__c = 'UTF-8';
    con1.TimeZoneSidKey__c = 'America/Los_Angeles';
    insert con1;

    lcontact.add(con);
    lcontact.add(con1);

       PageReference pageRef = Page.ContactPortalUser;
        Test.setCurrentPage(pageRef);
          system.debug('*****1****' +  lcontact);     
     ApexPages.StandardSetController sc = new ApexPages.StandardSetController(Database.getQueryLocator([SELECT Id,Name FROM contact where id =:lcontact]));
ContactPortalUserController controller = new  ContactPortalUserController(sc);
  controller.selectedContact();
System.assert
      (ApexPages.getMessages().size() == 1);
      }
                    }
}
