I have written a schedule class to update the lead source to web if the lead source is null. I have written test class as well. But code coverage is 0% can anyone help me so that code coverage is 100%

Class 

global class LeadMaintanace implements Schedulable{
    global void execute(SchedulableContext SC) {
        List<Lead> li =[Select Id,Name from Lead where LeadSource = 'null' LIMIT 10];
        List<Lead> lu= new  List<Lead>();
        if(!li.isEmpty()){
            for(Lead ld:li){
                ld.LeadSource = 'Web';
                lu.add(ld);
            }
                }
        update lu;
    }

}

test class

@isTest
public class TestLeadMaintanace {
    @testsetup
    static void setup(){
        List<Lead> li = new List<Lead>();
        for(Integer i;i<10;i++){
            Lead ld = new Lead(Company = 'Proseraa',LastName ='MN',Status = 'Working - Contacted');
            li.add(ld);
            
            
        }
        update li;
        
    }
    static testmethod  void TestJobSchedule(){
        string sch = '0 30 12 2 20 ?';
        Test.startTest();
        string jobid=System.Schedule('SchedulableClass',sch, new LeadMaintanace());
        List<Lead> li =[Select Id from Lead where LeadSource=null limit 10];
        system.assertEquals(10,li.size());
        test.stopTest();
        
    }
    
    
}

I am getting below error

I have written a code to add all opportunity amount on quota object and display the list of all opportunity

I am getting the above error

Can anyone provide Test class for following use Case.
Consider all positive negative and bulk test case

Use case ::
Collection of Closed Won Opportunities
1. I have created a custom quota object
2. Create a VF page to display all the Closed won opportunities in the org Only if
1)The opportunitys cloased date lies between start and end date of quota
2)The User which is dispalyed in the assed to user should be the same as the owner
3) The record type is BDM

I have written the below test class for the same. I do not know how to write the logic can anyone help me with the same

I have written the below code to update bulk records to add all opportunity amount on quota object. Since it is a bulk record I have used asynchronous bulk update records.

        qutoaList = new list<quota__c>();
        oppList();

        Id qId = (Id) ApexPages.currentPage().getParameters().get('id');
        system.debug('Id-->'+qId);

        oppList1 = [Select Id, Name, CloseDate, StageName,OwnerId,Amount From Opportunity where StageName = 'Closed Won'];
        
        system.debug('quotaList1-->'+quotaList1);

I have written a test class to add all amount on quota which lies between start and end date of quota

I am getting below error

Can anyone provide Test class for following use Case.
Consider all positive negative and bulk test case

Use case ::
Collection of Closed Won Opportunities
1. I have created a custom quota object
2. Create a VF page to display all the Closed won opportunities in the org Only if
1)The opportunitys cloased date lies between start and end date of quota
2)The User which is dispalyed in the assed to user should be the same as the owner
3) The record type is BDM

I have written the below test class for the same. I do not know how to write the logic can anyone help me with the same

Apex class

public with sharing class listopponquota {
    
    public list<Opportunity> oppList{get;set;}

        oppList();

        system.debug('Id-->'+qId);

        oppList1 = [Select Id, Name, CloseDate, StageName,OwnerId,Amount From Opportunity where StageName = 'Closed Won'];
        
        system.debug('quotaList1-->'+quotaList1);
