Hello ... I have a very simple VF page that uses a standard controller extension. The Apex class returns a list of records that is populated in VF page. At present, I'm at a loss as to writting a test method for the APEX class.

Notice that in the apex I'm getting the record that has been selected by the user. So, in this simple case I'm returning to the VF page this selected record only. Can someone advise me how I can do a test method. Currently I'm creating a Account, opportunity, contract and assets in the test method. I don't  believe I'm defining the controller correctly since I always see 0% code covered in 'Run all tests' under Apex classes. So what do I need to do to get a valid test method written? Any help would be appreciated.

Regards,

Test Method:

     static testMethod void testToolsAEApex()  
    {
        Test.setCurrentPageReference(new PageReference('Page.ToolsAE'));
          ApexPages.standardController controller = new ApexPages.standardController(new Asset_Entitlement__c());
        Account a = new Account(Name='Becky Test');
        insert a;
        
        Opportunity  opp = new Opportunity();
        opp.Name='Test';
        opp.CurrencyIsoCode = 'USD';    
        opp.AccountId = a.Id;
        opp.Type = 'Term';
        opp.Type_2__c = 'Tools';
        opp.Sector__c = 'Academic';
        opp.CloseDate = system.today();
        opp.StageName = 'Proposal';
        opp.ForecastCategoryName = 'Pipeline';
        opp.OwnerId = '00550000000n1k8';
        
        insert opp;
        
        Contracts__c  con = new Contracts__c();
        con.Contract_Name__c='Test';
        con.CurrencyIsoCode = 'USD';
        con.Opportunity__c = opp.Id;    
 
        insert con;
        
        Asset_Entitlement__c asset = new Asset_Entitlement__c();  
        asset.Account_del__c = opp.AccountId;              
        asset.Opportunity_Owner__c = opp.OwnerId;      
        asset.CurrencyIsoCode = opp.CurrencyIsoCode;       
        //asset.Product__c = pricebookMap.get(oppLines.PricebookEntryId).Product2.Id;                               
        asset.End_Date__c = system.today() - 10;        
        asset.Invoice_Date__c = system.today();        
        asset.Unit_Price__c = 12;        
        asset.Opportunity__c = opp.Id;
        asset.Start_Date__c = system.today();                   
        asset.Status__c = 'Expired';
        asset.Entitlement_Status__c = 'Current';
        asset.Term__c = 12;        
        asset.RecordTypeId = '012500000001C2f';
        asset.Contracts__c = con.Id;                 
        asset.Quantity__c = 1;
        asset.DNR__c = false;
        asset.Renew_Flag__c = false;  
        asset.Part_Number__c = '2091Test-MNT';  

        asset.License_Type__c = 'Term';  
        insert asset;
        ApexPages.currentPage().getParameters().get(con.Id);

Here's the APEX Class:

public class ToolsAE {
  private final Asset_Entitlement__c AE;
  String i = '' ;
  String conId ='';
  String noRec = 'N';
  public ToolsAE(ApexPages.StandardSetController controller)
  {   
       List<Asset_Entitlement__c> aeId = (List<Asset_Entitlement__c>) controller.getSelected();
    Parent_Opty_Aggregate__c, Group_Number__c,  from Asset_Entitlement__c where id IN :aeId]; //IN :aeId
    for(Asset_Entitlement__c j:aeId)
    {
     i = j.Id;
    }
     if(i == null || i ==''){
          noRec = 'Y';
          conId = ApexPages.currentPage().getParameters().get('id'); // If no records get the current Contract to return to.
     }
   }
 
  public List <Asset_Entitlement__c> aeList
  {
     get {
         List<Asset_Entitlement__c> aeList = new List<Asset_Entitlement__c>();
         for (Asset_Entitlement__c a:[select id, Contracts__c, Name, Parent_Opty_Aggregate__c, Group_Number__c,
            Account_del__c, Entitlement_Status__c,Distrib_Method__c, Start_Date__c, End_Date__c,Term__c,Unit_Price__c,Total_Price__c
               from Asset_Entitlement__c where id  = :i])
        {
              aeList.add(a);
              conId = a.Contracts__c; //Grab the Contract Id so we can use it later to return to
        }
        if (noRec == 'Y')
       {
          ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR, 'No Header Aggregate Records  were selected.');
           ApexPages.addMessage(myMsg);
           return null;
       }
         else
        return aeList;
     }
     set;
   
 } 
 
   public PageReference ret() {
          PageReference conPage = new PageReference('/' + conId);//Return to Contract Page
          conPage.setRedirect(true);
          return conPage;
     }
}
