Create a Queueable Apex class that inserts the same Contact for each Account for a specific state. Write unit tests that achieve 100% code coverage for the class.
Create an Apex class called 'AddPrimaryContact' that implements the Queueable interface.
Create a constructor for the class that accepts as its first argument a Contact sObject and a second argument as a string for the State abbreviation.
The execute method must query for a maximum of 200 Accounts with the BillingState specified by the State abbreviation passed into the constructor and insert the Contact sObject record associated to each Account. Look at the sObject clone() method.
Create an Apex test class called 'AddPrimaryContactTest'.
In the test class, insert 50 Account records for BillingState "NY" and 50 Account records for BillingState "CA". Create an instance of the AddPrimaryContact class, enqueue the job and assert that a Contact record was inserted for each of the 50 Accounts with the BillingState of "CA".
The unit tests must cover all lines of code included in the AddPrimaryContact class, resulting in 100% code coverage.
Run your test class at least once (via 'Run All' tests the Developer Console) before attempting to verify this challenge.
Hi, I have problem in the challenge which is as follows : 
Create a Lightning Component to display a single item for your packing list.
  • Create a component called campingListItem that displays the name (ui:outputText) and the three custom fields using the appropriate output components.
  • Add an attribute named item for type Camping_Item__c that is required.
for this I made component campingListItem.cmp which has following code :
<aura:component>
    <aura:attribute name="item" type="Camping_Item__c" />    
    <p>Name:<ui:outputText value="{!v.item.Name}"/></p>    
    <p>Quantity:<ui:outputNumber value="{!v.item.Quantity__c}"/></p>    
    <p>Price:<ui:outputCurrency value="{!v.item.Price__c}"/></p>
    <p>Packed?:<ui:outputCheckbox value="{!v.item.Packed__c}"/></p>
</aura:component>

but data is not displaying from object simple HTML text is displaying as follows:
Name:
Quantity:
Price:
Packed?:  False

please give me some suggestion.

 
HI ,I am doing a trailhead on salesforce Lighting this is my code 

<aura:component >
    <aura:attribute name="item"  type="Camping_Item__c"  /> <!-- required="true" type="String"  -->
    <p> The Item is <ui:outputText value ="{!v.item}"></ui:outputText></p>
    <p>Name:
        <ui:outputText value="{!v.item.name}" /> 
    </p>

    <p>Quantity:
        <ui:outputNumber value="{!v.item.Quantity__c}" /> 
    </p>

    <p>Price:
        <ui:outputCurrency value="{!v.item.Price__c}" /> 
    </p>

    <p>Packed?:
        <ui:outputCheckbox value="{!v.item.Packed__c}" /> 
    </p>
    
    <p><ui:button label="Packed!" press="{!c.packItem}"></ui:button>
    </p>
</aura:component>



Now Its required of me to :
Add a button to the campingListItem component that when clicked, marks the item as packed.
1.Add a button labeled "Packed!" that calls the packItem controller function when clicked.
2.The controller action marks the item attribute as packed and disables the button.

I have done with the first point
I'm struggling with the second point.

the controller code looks something like this (which currently isnt working)

({
    packItem : function(component, event, helper) {
        var btn= event.getSource();
        var BtnMessage =btn.get("v.label");  
        component.set("v.item","Packed");          
        btn.disabled=false;
    }
})



each time I have failing the trailhead because of this error message
Challenge Not yet complete... here's what's wrong: 
The campingListItem JavaScript controller isn't setting the 'Packed' value correctly.



 
The 'AccountProcessor' class did not achieve 100% code coverage via your test methods. Make sure that you chose 'Run All' tests in the Developer Console at least once before attempting to verify this challenge. I did the run all with no luck. I did notice that this is the new section that was just added and I ran into issues in the first unit too.

Create an Apex class with a method using the @future annotation that accepts a List of Account IDs and updates a custom field on the Account object with the number of contacts associated to the Account. Write unit tests that achieve 100% code coverage for the class.
Create a field on the Account object called 'Number_of_Contacts__c' of type Number. This field will hold the total number of Contacts for the Account.
Create an Apex class called 'AccountProcessor' that contains a 'countContacts' method that accepts a List of Account IDs. This method must use the @future annotation.
For each Account ID passed to the method, count the number of Contact records associated to it and update the 'Number_of_Contacts__c' field with this value.
Create an Apex test class called 'AccountProcessorTest'.
The unit tests must cover all lines of code included in the AccountProcessor class, resulting in 100% code coverage.
Run your test class at least once (via 'Run All' tests the Developer Console) before attempting to verify this challenge.

public class AccountProcessor
{
  @future
  public static void countContacts(Set<id> setId)
  {
      List<Account> lstAccount = [select id,Number_of_Contacts__c , (select id from contacts ) from account where id in :setId ];
      for( Account acc : lstAccount )
      {
          List<Contact> lstCont = acc.contacts ;
         
          acc.Number_of_Contacts__c = lstCont.size();
      }
      update lstAccount;
  }
}

and
@IsTest
public class AccountProcessorTest {
    public static testmethod void TestAccountProcessorTest(){
        Account a = new Account();
        a.Name = 'Test Account';
        Insert a;

        Contact cont = New Contact();
        cont.FirstName ='Bob';
        cont.LastName ='Masters';
        cont.AccountId = a.Id;
        Insert cont;
       
        set<Id> setAccId = new Set<ID>();
        setAccId.add(a.id);
 
        Test.startTest();
            AccountProcessor.countContacts(setAccId);
        Test.stopTest();
       
        Account ACC = [select Number_of_Contacts__c from Account where id = :a.id LIMIT 1];
        System.assertEquals ( Integer.valueOf(ACC.Number_of_Contacts__c) ,1);
  }
 
}
this is my code but its not woking. any one can help

global class LeadProcessor implements Database.Batchable<sObject> {
    global Database.QueryLocator start(Database.BatchableContext bc){
          String query= 'SELECT Name, LeadSource from Lead';
        return Database.QueryLocator(query);
    }
    global void execute(Database.BatchableContext bc, List<Lead> scope){
        
        for(Lead l: scope){
            l.LeadSource ='Dreamforce';
           
        }
        update scope;
    }
    global void finish(Database.BatchableContext bc){
        
    }
}
Here is the Question


Create an Apex class that implements the Schedulable interface to update Lead records with a specific LeadSource. Write unit tests that achieve 100% code coverage for the class. This is very similar to what you did for Batch Apex.
Create an Apex class called 'DailyLeadProcessor' that uses the Schedulable interface.
The execute method must find the first 200 Leads with a blank LeadSource field and update them with the LeadSource value of 'Dreamforce'.
Create an Apex test class called 'DailyLeadProcessorTest'.
In the test class, insert 200 Lead records, schedule the DailyLeadProcessor class to run and test that all Lead records were updated correctly.
The unit tests must cover all lines of code included in the DailyLeadProcessor class, resulting in 100% code coverage.
Run your test class at least once (via 'Run All' tests the Developer Console) before attempting to verify this challenge.


Here is my code so far

global class DailyLeadProcessor implements Schedulable {

    global void execute(SchedulableContext ctx) {
        list<leads>Lead = [select leadSource from lead where isnull= true]
        
         for (Integer i = 0; i < 200; i++) {
            Leads.add(new lead(
                name='Dream force'+i
            ));
        }
        insert Leads;
    }

I am not sure what is wrong here
Hi,

I have a question. I can see this code is working fine in my org 
<apex:page standardController="Opportunity">
    <apex:outputLabel>{!Opportunity.Name}</apex:outputLabel>
    <apex:outputLabel>{!Opportunity.StageName}</apex:outputLabel>
    <apex:outputText value="{!IF(Opportunity.StageName=="Prospecting", 'Test 1', IF(Opportunity.StageName=="Proposal/Price Quote", 'Test 2', IF(Opportunity.StageName=="Needs Analysis", 'Test 3', IF(Opportunity.StageName=="Negotiation/Review", 'Test 4','Test 5'))))}"/>
</apex:page>


But the challange keeps saying:

Challenge not yet complete... here's what's wrong: 
The page isn't evaluating the 'Negotiation Review' stage.


Very frustrating. Anyone an idea?
Much appreciated in advance.
