In this tutorial, we are going to cover the Module called “Asynchronous Apex in salesforce“. In this lecture, you are going to get introduced to the platform, navigate use cases, and build custom functionality. Click here to solve the quiz Asynchronous Apex in salesforce.
#1.Asynchronous Processing Basics
Solve these tests and get 100 points
Q1)What is a key benefit of asynchronous processing?
I)Higher governor and execution limits
II)Unlimited number of external callouts
III)Override organization-wide sharing defaults
IV)Enabling turbo mode for transactional processing

Q2)Batch Apex is typically the best type of asynchronous processing when you want to:
I)Make a callout to a web service when a user updates a record.
II)Schedule a task to run on a weekly basis.
III)Update all records in your org.
IV)Send a rickroll email to a contact.

#2.Use Future Methods
Hands-on Challenge
Solve the challenge and get 500 points
YOUR CHALLENGE
Create an Apex class that uses the @future annotation to update Account records.
Create an Apex class with a future method 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. Every hands-on challenge in this module asks you to create a test class.
#Create a field on the Account object:
#Label: Number Of Contacts
#Name: Number_Of_Contacts
#Type: Number
#This field will hold the total number of Contacts for the Account
#Create an Apex class:
#Name: AccountProcessor
#Method name: countContacts
#The method must accept a List of Account IDs
#The method must use the @future annotation
#The method counts the number of Contact records associated to each Account ID passed to the method and updates the ‘Number_Of_Contacts__c’ field with this value
#Create an Apex test class:
#Name: AccountProcessorTest
#The unit tests must cover all lines of code included in the AccountProcessor class, resulting in 100% code coverage.
#Before verifying this challenge, run your test class at least once using the Developer Console Run All feature

#3.Use Batch Apex
Hands-on Challenge
Solve the challenge and get 500 points
YOUR CHALLENGE
Create an Apex class that uses Batch Apex to update Lead records.
Create an Apex class that implements the Database. Batchable interface to update all Lead records in the org with a specific LeadSource.
#Create an Apex class:
#Name: LeadProcessor
#Interface: Database.Batchable
#Use a QueryLocator in the start method to collect all Lead records in the org
#The execute method must update all Lead records in the org with the LeadSource value of Dreamforce
#Create an Apex test class:
#Name: LeadProcessorTest
#In the test class, insert 200 Lead records, execute the LeadProcessor Batch class and test that all Lead records were updated correctly
#The unit tests must cover all lines of code included in the LeadProcessor class, resulting in 100% code coverage
#Before verifying this challenge, run your test class at least once using the Developer Console Run All feature

#4.Control Processes with Queueable Apex
Hands-on Challenge
Solve the challenge and get 500 points
YOUR CHALLENGE
Create a Queueable Apex class that inserts Contacts for Accounts.
Create a Queueable Apex class that inserts the same Contact for each Account for a specific state.
#Create an Apex class:
#Name: AddPrimaryContact
#Interface: Queueable
#Create a constructor for the class that accepts as its first argument a Contact subject and a second argument as a string for the State abbreviation
#The execute method must query for a maximum of 200 Accounts with the BillingName specified by the State abbreviation passed into the constructor and insert the Contact Object record associated with each Account. Look at the subject clone() method.
#Create an Apex test class:
#Name: AddPrimaryContactTest
#In the test class, insert 50 Account records for BillingName NY and 50 Account records for BillingName 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 BillingName of CA
#The unit tests must cover all lines of code included in the AddPrimaryContact class, resulting in 100% code coverage
#Before verifying this challenge, run your test class at least once using the Developer Console Run All feature

#5.Schedule Jobs Using the Apex Scheduler
Hands-on Challenge
Solve the challenge and get 500 points
YOUR CHALLENGE
Create an Apex class that uses Scheduled Apex to update Lead records.
Create an Apex class that implements the Schedulable interface to update Lead records with a specific LeadSource. (This is very similar to what you did for Batch Apex.)
#Create an Apex class:
#Name: DailyLeadProcessor
#Interface: Schedulable
#The execute method must find the first 200 Lead records with a blank LeadSource field and update them with the LeadSource value of Dreamforce
#Create an Apex test class:
#Name: 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.
#Before verifying this challenge, run your test class at least once using the Developer Console Run All feature
