Given a list of Opportunity records named opportunityList, which code snippet is best for querying all Contacts of the Opportunity’s Account?

March 23, 2021March 23, 2021 konaguru Leave a comment

code Snippet #1 is the correct answer as you won’t end up pulling duplicate contacts into the contact list

Code Snippet #1:

List<Opportunity> OpportunityList = [select id, accountId from Opportunity];

List<Contact> contactList = new List<Contact>(); 
Set<Id> accountIds = new Set<Id>();
 
for(Opportunity o : opportunityList) { accountIds.add(o.AccountId);
}

for(Account a : [SELECT Id, (SELECT Id FROM Contacts) FROM Account WHERE Id IN :accountIds])
{
contactList.addAll(a.Contacts);
}
System.debug(' ContactList Size ' + contactList.size());

List<Opportunity> OpportunityList = [select id, accountId from Opportunity];

List<Contact> contactList = new List<Contact>();

Set<Id> accountIds = new Set<Id>();

for(Opportunity o : opportunityList) { accountIds.add(o.AccountId);

}

for(Account a : [SELECT Id, (SELECT Id FROM Contacts) FROM Account WHERE Id IN :accountIds])

{

contactList.addAll(a.Contacts);

}

System.debug(' ContactList Size ' + contactList.size());

Code Snippet #2 : Issue: Coding Error : List defined incorrectly

List<Opportunity> OpportunityList = [select id, accountId from Opportunity];

List<Contact> contactList = new List()<Contact>; 
Set<Id> accountIds = new Set<Id>(); 
for(Opportunity o : opportunityList) {
   contactIds.add(o.ContactId);
}
 for(Contact c : [SELECT Id FROM Contact WHERE Id IN :contactIds]){ 
    contactList.add(c);
}

List<Opportunity> OpportunityList = [select id, accountId from Opportunity];

List<Contact> contactList = new List()<Contact>;

Set<Id> accountIds = new Set<Id>();

for(Opportunity o : opportunityList) {

contactIds.add(o.ContactId);

}

for(Contact c : [SELECT Id FROM Contact WHERE Id IN :contactIds]){

contactList.add(c);

}

Code Snippet #3 :

List<Opportunity> OpportunityList = [select id, accountId from Opportunity];
System.debug(' Opportunity List ' + OpportunityList);
List<Contact> contactList = new List<Contact>(); 
for(Opportunity o : opportunityList) {
    System.debug(' Opportunity Account Id ' + o.accountId );
    if(o.accountId != null ) {
 Account a = [SELECT Id, (SELECT Id FROM Contacts) FROM Account WHERE Id = :o.AccountId];
   contactList.addAll(a.Contacts);
    }
}
System.debug(' Size of Contact List ' + contactList.size());

List<Opportunity> OpportunityList = [select id, accountId from Opportunity];

System.debug(' Opportunity List ' + OpportunityList);

List<Contact> contactList = new List<Contact>();

for(Opportunity o : opportunityList) {

System.debug(' Opportunity Account Id ' + o.accountId );

if(o.accountId != null ) {

Account a = [SELECT Id, (SELECT Id FROM Contacts) FROM Account WHERE Id = :o.AccountId];

contactList.addAll(a.Contacts);

}

System.debug(' Size of Contact List ' + contactList.size());

Code Snippet #4 : Issue: Coding error : you can’t read a list directly from OpportunityList

List<Opportunity> OpportunityList = [select id, accountId from Opportunity];

List<Contact> contactList = new List<Contact>();
for(Contact c : [SELECT Id FROM Contact WHERE AccountId IN :opportunityList.accountId]){ contactList.add(c);
}

List<Opportunity> OpportunityList = [select id, accountId from Opportunity];

List<Contact> contactList = new List<Contact>();

for(Contact c : [SELECT Id FROM Contact WHERE AccountId IN :opportunityList.accountId]){ contactList.add(c);

}

Test.startTest and Test.stopTest for asynchronous execution

March 23, 2021March 23, 2021 konaguru Leave a comment

You can also use this method with stopTest to ensure that all asynchronous calls that come after the startTest method are run before doing any assertions or testing. Each test method is allowed to call this method only once. All of the code before this method should be used to initialize variables, populate data structures, and so on, allowing you to set up everything you need to run your test. Any code that executes after the call to startTest and before stopTest is assigned a new set of governor limits.

@isTest
public class testIncrement {
    
    @isTest
    static void testIncrement2() {
        
        Account acct = new Account(Name='test');
        acct.Number_of_Times_Viewed__c = 0;
        insert acct;
   
        System.debug(' Account Id ' + acct.id);
        
        Test.startTest();
     
        AuditUtil.incrementViewed(acct.id);
        
        Test.stopTest();
    
        Account acctAfter = [ select Number_of_Times_Viewed__C from Account where Id = :acct.id];  
        System.assertEquals(1, acctAfter.Number_of_Times_Viewed__c);
        
        
    }

Test.stopTest();

            		accountObj = [select Number_of_Times_Viewed__c from account where id = :accountId ];
            accountObj.Number_of_Times_Viewed__c = accountObj.Number_of_Times_Viewed__c + 1;
            upsert accountObj;
