Roy, Thank you for your time.

A lot of this code isn't mine, and so I'm trying to track down what I can do to resolve this. So I'm not sure which code to post up here. (All of the code I've written is above the 75 percent code coverage). I've found 6 Classes and/or triggers that are under 75 percent.... They aren't part of the deployment packaged, but are you saying they can affect deployment? - I still can't figure out what the 55 percent is coming from.

If so, I've asked the company which of these are unneccessary (so they can just be removed) and which one need to have better test classes created for them.

To clarifiy. In the test classes I have written... I have used @isTest in front of them.. but have not used the (SeeAllData=True) I assume that I'm okay with that method?

---- Here is the Class that is being attempted to deploy from Sandbox to Live.... in the Sandbox it is listing as 86 percent Coverage.

But when trying to deploy it, it says it's at 55 percent??

public class SSORedirectController{
    String url;
    String ContactId;
    public SSORedirectController(){
        url = ApexPages.currentPage().getParameters().get('dest');
        String userId = userInfo.getUserId();
        ContactId = [Select id, ContactId From User Where id =: userId].ContactId;
    }
    
    public PageReference redirectToPage(){
        if(ContactId != null){
            PageReference pg = new PageReference(url);
            pg.setRedirect(true);
            return pg;
        }
        else{
            ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR, 'Cannot redirect to '+url+' for this user.'));
            return null;
        }
    }
    
    @isTest
    public static void test1() {
    
    Account a = new Account(Name='Test Account Name');
  insert a;
 
  Contact c = new Contact(LastName = 'Contact Last Name', AccountId = a.id);
  insert c;
 
  User user = new User();
  user.ProfileID = [Select Id From Profile Where Name='LEE Member Portal'].id;
  user.EmailEncodingKey = 'ISO-8859-1';
  user.LanguageLocaleKey = 'en_US';
  user.TimeZoneSidKey = 'America/New_York';
  user.LocaleSidKey = 'en_US';
  user.FirstName = 'first';
  user.LastName = 'last';
  user.Username = 'test@appirio.com';   
  user.CommunityNickname = 'testUser123';
  user.Alias = 't1';
  user.Email = 'no@email.com';
  user.IsActive = true;
  user.ContactId = c.Id;
 
  insert user;
        
        

System.runAs(user){
            ApexPages.currentPage().getParameters().put('dest','http://www.google.com');
            SSORedirectController src = new SSORedirectController();
            src.redirectToPage();
        }
   }
