Hello ,

I am very new to Apex code and I am facing difficulties in my unit test code. The main functionality of the trigger is to assign a standard campaign to the leads based on the lead hub score. I wrote a unit test the code and it is as follows

@istest
public class LeadCampaignTestClass{
private static testMethod void testclass1 () {
//Create one campaign record
Campaign ca = new Campaign(Name='Test Campaign');
//required fields
insert ca;
// create a lead record
Lead le = new lead();
//required fields
le.hub_spot_score__c = 25;
insert le;
// adding a campaign member
List<CampaignMember> members = [SELECT Id FROM CampaignMember
WHERE LeadId
= :le.Id AND CampaignID = :ca.Id];
System.assertEquals(1, members.size());
}
// Negative test class
private static testMethod void testclass2(){
//Create one campaign record
Campaign ca = new Campaign(Name='Test Campaign');
insert ca;
//create lead record
Lead le = new lead();
//No hub score is added
insert le;
List<CampaignMember> members = [SELECT Id FROM CampaignMember WHERE LeadId
= :le.Id AND CampaignID = :ca.Id];
System.assertEquals(1, members.size());
}
}

When I tried to run the test , the foowing error was displayed :

Can some one help me with this issue asap .
