Hi All,

  Here is my trigger, and I have got an error while writing the test class.

trigger UpdateRating on Lead (before update) {
    for(Lead l:Trigger.new)
    {
        if(l.Pardot_Rating__c !=null && l.Pardot_Rating__c =='A')
        {
         l.Rating = 'A';
        }
       else if(l.Pardot_Rating__c !=null && l.Pardot_Rating__c =='B')
        {
         l.Rating ='B';
        }
       else if(l.Pardot_Rating__c !=null && l.Pardot_Rating__c =='C')
        {
         l.Rating = 'C';
        }
     }
}

    Here is the Test Class.

@isTest(seeAllData = true)
Private Class TestUpdateRatingTrigger{
 @isTest
 Private Static Void testUpdateRatingTrigger(){
     Test.StartTest();
     Lead testLead = new Lead(
       FirstName = 'TestFirstName',
       LastName = 'TestLastName',
       Email = 'Srinu.mandalapu@stratus.com',
       Phone = '4055090045',
       Prospect_Type__c = 'Direct End User',       
       Title = 'Test Title',
       Company = 'ABC',      
       Status = 'Open',
       Rating = 'A'     
     );
     insert testLead;
     testLead.Rating  = 'B';
     update testLead;
     //verifying updation
     Lead updatedLead = [SELECT Rating FROM Lead WHERE Id = :testLead.Id];
     System.assertEquals('B', updatedLead.Rating);     
     Test.StopTest();
    
 }
}

   Error:

System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, jigsaw_clean.crmLastModifiedLead: execution of BeforeInsert caused by: line -1, column -1: Previous load of class failed: knowledgecontroller: []

Class.TestUpdateRatingTrigger.testUpdateRatingTrigger: line 17, column 1

   Here "KnowledgeController" is the controller in my org.

  Is "knowledgeController" managed package in my org? I saw the packages in my ORG, I did not find any package under that name...

  Any help would be greatly aprreciated...
