}

public PageReference GetList()

}
}


and the Test class  I  wrote is
 
ERROR :System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Name__c]: [Name__c]



And i have only one required field in employee object 
Name__c  and data type is    Text(20)
rest of the fields are 
Desig__c 
  Age__c 
Salary__c 
Qualification__c


@istest
public class Testclass
{

public static testmethod void Employee()
{

Employee e = new Employee();

Employee__c empc = new Employee__c();

empc.Name__c = 'Test Name';
empc.Desig__c = 'Testy Designation';
empc.Age__c = 18;
empc.Salary__c = 100;
empc.Qualification__c = 'BE';

insert empc;

e.save();
e.saveAndNew();
e.Clear();
e.GetList();

}
}



Thanks in Advance
