Hi, I am learning SF developer. I created 100 records in Account object using SQL query. then im trying to delete all those records using SOQL query and for loop here is my code:
list<Account> newlist=new list<Account>();
newlist=[SELECT Id,Name FROM Account WHERE Name='test name'];
system.debug('list'+newlist);
list<Account> deletelist=new list<Account>();
for(Account a: newlist){
    a.Name='test name';
    deletelist.add(a);
}
system.debug('list'+deletelist);
delete deletelist;
but i am unable to delete. i know i can use work bench for this but i want to delete using SOQL here is the error im facing:
Line: 10, Column: 1
System.DmlException: Delete failed.

I'm doing the "Test Apex Triggers" challenge and get this error:
"The 'RestrictContactByName' class did not achieve 100% code coverage via your test methods"

I also attach my code here, can you show me where could it be the wrong spot?
 

@isTest
public class TestRestrictContactByName {
    @isTest static void TestInsertContact_INVALIDNAME(){
		Contact contact = new Contact(LastName='INVALIDNAME');
        Test.startTest();
        Database.SaveResult result = Database.insert(contact);
        Test.stopTest();
        System.assert(!result.isSuccess());
        System.assert(result.getErrors().size() > 0);
        System.assertEquals('The Last Name "'+contact.LastName+'" is not allowed for DML',
                             result.getErrors()[0].getMessage());
    }
    
    @isTest static void TestInsertContact_VALIDNAME(){

        Test.startTest();
        Database.SaveResult result = Database.insert(contact);
        Test.stopTest();
        System.assert(result.isSuccess());
    }
    
    @isTest(SeeAllData=true) static void TestUpdateContact_INVALIDNAME(){

Hi,
I have to simply call a lightning component from a VisualForce Page. Later this VF page is configured as a list button in Opportunity.
VF Page::

<apex:page standardController="Opportunity" recordSetVar="opp"  tabStyle="Opportunity"> 
<apex:includeLightning />
 <script>
    //    var recordid = "{!$CurrentPage.parameters.id}";    
         $Lightning.use("c:LightningOutContainerApp", function() {
         $Lightning.createComponent("c:RelatedListNewRecordPOC",
         { 
         oppRecordId : "0069000000x6KWSAA2" 
         },
         "RelatedListNewRecordPOCContainer",
         function(cmp) {
         console.log('Component created, do something cool here');
         });
         });
 </script>
</apex:page>

Lightning App:

<aura:application access="GLOBAL" extends="ltng:outApp">
 	<aura:dependency resource="c:RelatedListNewRecordPOC"/>	
</aura:application>

Component:

<aura:component controller="RelatedListNewRecordPOCController" implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,forceCommunity:availableForAllPageTypes" access="global" >
    <aura:attribute name="oppRecordId" type="String"/>
    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
</aura:component>

JS Controller:

({

    doInit: function(component, event, helper) {
        var myRecordId = "0069000000x6KWSAA2";//component.get("v.recordId");
        var getParameters = component.get('c.getParameters');
        getParameters.setParams({
            "myRecordId": myRecordId
        });

        getParameters.setCallback(this, function(response) {
            var state = response.getState();
            if (state === "SUCCESS") {
                var Opportunity = response.getReturnValue();               
                var createAcountContactEvent = $A.get("e.force:createRecord");
                createAcountContactEvent.setParams({
                    "entityApiName": "Opportunity",
                    "RecordTypeId": Opportunity.RecordTypeId,
                    "defaultFieldValues": {
                        'AccountId': Opportunity.AccountId,
                        'Name': Opportunity.Name,
                        'StageName':Opportunity.StageName,
                        'CloseDate':Opportunity.CloseDate
                    }
                });
                createAcountContactEvent.fire();

            } else {
                var closeAction = $A.get("e.force:closeQuickAction");
                closeAction.fire();
            }
        });
        $A.enqueueAction(getParameters);
        $A.get("e.force:closeQuickAction").fire();
    },
})

Apex Controller:

public class RelatedListNewRecordPOCController {
    
    @AuraEnabled
    public static Opportunity getParameters(Id myRecordId){
        return [SELECT Id, AccountId, RecordTypeId, Name, Description, StageName, Amount
                , TotalOpportunityQuantity, CloseDate, Type, LeadSource, IsClosed FROM Opportunity WHERE Id =: myRecordId ];    }
	
}

Here I'm getting an error while calling the getParameters() function from LC only when from VF page which is configured in list button.
If I run the LC from actions, it is working.
Error:  $A.getCallback() [Unable to get property 'setParams' of undefined or null reference] Callback failed: apex://RelatedListNewRecordPOCController/ACTION$getParameters
Can anyone please help. As per requirement I have to configure it in list button and I'm not able to dibug this.
