Hello all,

I wrote a web service to insert  values into object. Its working fine. but when I am tring to call it from Test method I am not able to get the lookup values The query returnig zero values. 

My Web service:

try
{         RestRequest req = RestContext.request;
         String bdy = req.requestBody.toString(); 
         new_whitepaper_registration whitepaper = (new_whitepaper_registration)JSON.Deserialize(bdy,new_whitepaper_registration.class);
         White_Papers__c ObjWhitePaper =New White_Papers__c(); 
 		 ObjWhitePaper.Name=whitepaper.Name;
 		 ObjWhitePaper.Document_Name__c=whitepaper.DocumentName;
         ObjWhitePaper.White_Paper_Id__c=whitepaper.WhitePaperId;  		
         ObjWhitePaper.Lead_Name__c=[select ID from Lead where Name=:whitepaper.LeadName Limit 1].ID;   
 		insert ObjWhitePaper;	
         
   return new ReturnClass('True');
}
catch(Exception ex)
{
system.debug('ERROR: '+ex.getMessage()+ ' '+ex.getStackTraceString());   
 return new ReturnClass('false');
    
}

My Test Class: 
 

@isTest
public class CreateNewWhitePaperTest {
static testmethod void TestCreateNewWhitePaper()
    {
        RestRequest req = new RestRequest();
        RestResponse res = new RestResponse();
        req.requestURI = 'https://offerboard--dev1.cs17.my.salesforce.com/services/apexrest/CreateWhitePaper';  
      req.httpMethod = 'POST';
        req.requestBody=Blob.valueof('{"Name":"Test White Paper","WhitePaperId":"123","DocumentName":"Demo Doc","LeadName":"Punam Sharma"}');
        RestContext.request = req;
       RestContext.response = res;
        CreateWhitePaper.ReturnClass results = CreateWhitePaper.NewWhitePaper();      
      
   		 System.assertEquals('True', results.success);
       
       
      
        
      
    }
}
