Please help me with parent to child test class

I am trying to update the AnnualRevenue of Account into Opportunity amount and it is working for update.....During testing I am getting error System Variable does not exist: Amount
Here is the code
@isTest
public class OppAmountUpdate_Test {
    @isTest
    public static void myMethod_Test(){
        
        Account acc = new Account();
        //acc.Id = '0015j00000dkZj0AAE';
        acc.Name = 'Aviral Dandge';
        acc.AnnualRevenue = 25000;
        insert acc;
        
        Opportunity opp1 = new Opportunity();
        opp1.Name = 'Dandge Pvt Ltd';
        opp1.CloseDate = system.today();
        opp1.StageName = 'Qualification';
        insert opp1;
        
        Test.startTest();
        acc.AnnualRevenue = 50000;
        update acc;
        Test.stopTest();
        
        /*Opportunity oppNew = new Opportunity();
        oppNew.AccountId = acc.Id;*/
        /*Account newAcc = [Select Name, Id, AnnualRevenue from account where Id =: acc.Id];
        system.assertEquals(25000, acc.AnnualRevenue);*/
        
        List<Opportunity> opp = [Select AccountId, id, Amount from Opportunity 
                           where AccountId =:acc.Id];
        
        
        system.assertEquals(50000, opp.Amount);
        
            
        
        
    }

}

Now I am getting error  List has no rows for assignment to SObject for the query List<Opportunity> opp = [Select AccountId, id, Amount from Opportunity                             where AccountId =:acc.Id];
Bad Bunny MerchBad Bunny Merch
There list has no error, (https://badbunnymerch.biz/) please check the query List<Opportunity> opp = [Select AccountId, id, Amount from Opportunity                             where AccountId =:acc.Id];

Hi Akshat,

The error is coming due to the below line: 

system.assertEquals(50000, opp.Amount);  ====>    opp[0].Amount

Opp is a List so use the opp[0].
List<Opportunity> opp = [Select AccountId, id, Amount from Opportunity 
                           where AccountId =:acc.Id];
        
        
system.assertEquals(50000, opp[0].Amount);

Thanks,

Thank you for responding @Maharajan C, @
Bad Bunny Merch and @mukesh gupta I made 'system.assertEquals(50000, opp[0].Amount)'; and 'opp1.AccountId = acc.Id;' these modifications on the code and its working

Can I get some more clarity on why we are using opp[0] and not any other  integer like opp[1] and when to use this?

Hi Akshat,
 

Because we are using List that's have index 0,1,2 etc.
 
 List<Opportunity> oppList = [Select AccountId, id, Amount from Opportunity where AccountId =:acc.Id]; system.assertEquals(50000, oppList[0].Amount);
we can access only 0 index because Account have only one opportunity that's why we are using [0],   if we try to use [1] then will face error becaue opportuity available on 0 index.

Please use below code:-
 
@isTest
public class OppAmountUpdate_Test {
    @isTest
    public static void myMethod_Test(){
        
        Account acc = new Account();
        //acc.Id = '0015j00000dkZj0AAE';
        acc.Name = 'Aviral Dandge';
        acc.AnnualRevenue = 25000;
        insert acc;
        
        Opportunity opp1 = new Opportunity();
		opp1.AccountId = acc.Id;
        opp1.Name = 'Dandge Pvt Ltd';
        opp1.CloseDate = system.today();
        opp1.StageName = 'Qualification';
		opp1.Amount = 2000;
        insert opp1;
        
        Test.startTest();
        acc.AnnualRevenue = 50000;
        update acc;
        Test.stopTest();
        
        /*Opportunity oppNew = new Opportunity();
        oppNew.AccountId = acc.Id;*/
        /*Account newAcc = [Select Name, Id, AnnualRevenue from account where Id =: acc.Id];
        system.assertEquals(25000, acc.AnnualRevenue);*/
        
        List<Opportunity> oppList = [Select AccountId, id, Amount from Opportunity 
                           where AccountId =:acc.Id];
        
        
        system.assertEquals(50000, oppList[0].Amount);
        
            
        
        
    }

}
