Can you test an asynchronous code in apex?
Because of the way Asynchronous Apex works, any asynchronous code – a future method is a useful example – will not be executed during the confines of an Apex unit test unless we take specific action.
How to write asynchronous apex-sfdevops unit test?
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. Write unit tests that achieve 100% code coverage for the class. This is very similar to what you did for Batch Apex.
What does asynchronous apex mean in Salesforce?
