Controlling Processes with Queueable Apex

The solution to this trailhead challenge is inside of the reading of the trailhead material, and the challenge references the LeadProcessor class from the Database.Batchable trailhead challenge which does not apply to this challenge.

Try below code. I hope that will help you 
global class LeadProcessor implements    Database.Batchable<Sobject> 
{
    global Database.QueryLocator start(Database.BatchableContext bc) 
    {
        return Database.getQueryLocator([Select LastName From Lead ]);
    }

    global void execute(Database.BatchableContext bc, List<Lead> scope)
    {
            for (Lead Leads : scope) 
            {
                Leads.LeadSource = 'Dreamforce';
            }
        update scope;
    }    

    global void finish(Database.BatchableContext bc){   }    
}
@isTest 
public class LeadProcessorTest 
{
    static testMethod void testMethod1() 
    {
        List<Lead> lstLead = new List<Lead>();
        for(Integer i=0 ;i <200;i++)
        {
            Lead led = new Lead();
            led.FirstName ='FirstName';
            led.LastName ='LastName'+i;
            led.Company ='demo'+i;
            lstLead.add(led);
        }
        
        insert lstLead;
        
        Test.startTest();

            LeadProcessor obj = new LeadProcessor();
            DataBase.executeBatch(obj); 
            
        Test.stopTest();
    }
}

Let us know if this will help you

Can anyone give the solution to the AddPrimaryContact challenge? It talks abouta Clone() method, but I'm not sure how to implement that in the execute method. Thanks in advance!

It is for the 'Controlling Processes with Queueable Apex' challenge.

@Amit

Used your code. Worked perfectly. Thanks mate!

I am glad that's helped you Manjunath ,

Hi David Steele,

Please let us know if above solution will helped you or you need more help

@Amit

Thank you for your help. That definitely got me on the right track.

I don't see any assertions in your test class, though. As per the instructions, we must "assert that a Contact record was inserted for each of the 50 Accounts with the BillingState of 'CA'."

Working code sample created by me... Hope help to somebody.
  
public class AddPrimaryContact implements Queueable {

    private Contact cont;
    private String state;
    
    public AddPrimaryContact(Contact record, String sta) {
        this.cont = record;
        this.state = sta;
    }
    
    
    public void execute(QueueableContext context) {
        List<Account> accounts = [select id from account where BillingState = :state LIMIT 200];
        for (Account account : accounts) {
            Contact ct = cont.clone();
            ct.AccountId=account.id;
            upsert ct;
        }

Hello everyone. I'm having an issue with this one in trailhead and was wondering if someone could provide assistance. Specifically, the test class is failing 
public class AddPrimaryContact implements Queueable {
    
    private Contact con;
    private String ab;
    
    public AddPrimaryContact (Contact cont, String abb){
        this.con= cont;
        this.ab = abb;
    }
    public void execute(QueueableContext qc){
        List<Account> acc = [select id from account where billingstate = :ab limit 200];
        for(Account a : acc){
            Contact cc = con.clone();
            cc.accountId = a.Id;
            insert cc;
        }
        
    
    }

}
@isTest
private class AddPrimaryContactTest{

@testSetup

static void Starting(){
    List<Account> acc = new List<Account>();
    for(Integer i=1; i< 51; i++){
        acc.add(new Account(name='Sample Name' + i, billingstate = 'NY'));
        acc.add(new Account(name='Sample Name' + i, billingstate = 'CA'));
    }
    insert acc;
    }
    static testMethod void testQueueable(){
    
        Contact ct = new Contact(lastname='something');
        String st = 'CA';
        
        AddPrimaryContact apc = new AddPrimaryContact (ct,st);
        
        Test.startTest();
            System.enqueueJob(apc);
        Test.stopTest();
        
        System.assertEquals(50,[select count() from account where billingstate = :st]);
    }
}

Well the test class isn't failing, more that the trailhead check is
Calin Fintzi 13Calin Fintzi 13
Maybe it's just me but I don't see how the query that's been written in all these system.assertEqulas statements confirm that all the 50 accounts with billingstate = CA in fact have contacts that they are associated with???
My understanding is that count() is only counting the accounts what fit the WHERE condition but there's nothing about the number of contacts with one related to one of these accounts?
Josiah Anderson 2Josiah Anderson 2
This is what you need Calin:
  
System.assertEquals(50, [ SELECT count() FROM Contact WHERE AccountId IN (SELECT Id FROM Account WHERE BillingState = 'CA') ]);

Can someone help. I used same code as amitUser-added image

Hi,
Please check the following solution. It works!!!!!I passed the challenge with 100% code coverage and Assert statement passed!!!!!!!!

Class: AddPrimaryContact 

public class AddPrimaryContact implements Queueable{
    private Contact c;
    private String state;
    public AddPrimaryContact(Contact contact, String state){
        this.c = contact;
        this.state = state;
    }
    
    public void execute(QueueableContext context){
        List<Account> accounts = [Select ID, Name From Account WHERE BillingState =:state LIMIT 200];
        List<Contact> contacts = new List<Contact>();
        for(Account account: accounts){
            Contact con = c.clone(false, false,false, false);
            con.AccountId = account.Id;
            contacts.add(con);
            
        }
        if(contacts.size()>0){
            insert contacts;
        }
    }

}

Test Class: AddPrimaryContactTest
@isTest
public class AddPrimaryContactTest {
    static testmethod void testQueueable(){
        List<Account> testAccounts = new List<Account>();
        for(Integer i=0; i<50; i++){
            testAccounts.add(new Account(BillingState = 'NY', name = 'QueueTest ' + i));
        }
        for(Integer j=0; j<50; j++){
            testAccounts.add(new Account(BillingState = 'CA', name = 'QueueTest ' + j));
        }
        insert testAccounts;
        Contact con = new Contact(FirstName = 'Queueable', LastName = 'Apex');
        insert con;
        AddPrimaryContact primContact = new AddPrimaryContact(con, 'CA');
        Test.startTest();
        System.enqueueJob(primContact);
        Test.stopTest();
        System.assertEquals(50, [SELECT count() FROM Contact WHERE accountId IN (Select id from Account WHERE BillingState ='CA')]);
    }

}
