Consider the following code snippet:
HTML
<c-selected-order>
<template for:each={orders.data} for:item="order">
<c-order orderId={order.Id}></c-order>
</template>
</c-selected-order>
How should the <c-order> component communicate to the <c-selected-order> component that an order has been selected by the user?

public class searchFeature {
public static List<List<object>> searchRecords(string searchquery) {
return [FIND :searchquery IN ALL FIELDS RETURNING Account, Opportunity, Lead];
}
}
// Test Class
@isTest
private class searchFeature_Test {
@TestSetup
private static void makeData() {
//insert opportunities, accounts and lead
}
private static searchRecords_Test() {
List<List<object>> records = searchFeature.searchRecords('Test');
System.assertNotEquals(records.size(),0);
}
}
However, when the test runs, no data is returned and the assertion fails. Which edit should the developer make to ensure the test class runs successfully?

The Account object has a field, Audit_Code__c, that is used to specify what type of auditing the Account needs and a Lookup to User, Auditor__c, that is the assigned auditor. When an Account is initially created, the user specifies the Audit_Code__c. Each User in the org has a unique text field, Audit_Code__c, that is used to automatically assign the correct user to the Account's Auditor__c field.
Trigger:
Java
trigger AccountTrigger on Account (before insert) {
AuditAssigner.setAuditor(Trigger.new);
}
Apex Class:
Java
public class AuditAssigner {
public static void setAuditor(List<Account> accounts) {
for (User u : [SELECT Id, Audit_Code__c FROM User]) {
for (Account a : accounts) {
if (u.Audit_Code__c == a.Audit_Code__c) {
a.Auditor__c = u.Id;
}
}
}
}
}
What should be changed to most optimize the code's efficiency?
