Create an Apex class that uses the @future annotation to update Account records – Asynchronous Apex
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.
