To test callouts, use mock callouts by either implementing an interface or using static resources."— Apex Developer Guide: Testing HTTP Callouts, Option B: Execute anonymous Apex as a different user, Executing anonymous Apex isn't possible within a test method, and you can't change the user context arbitrarily in tests except with System.runAs, which doesn't execute as a different user for anonymous code., Reference:, "You can use System.runAs to run code as a different user, but you cannot execute anonymous Apex in this way within a test."— Apex Developer Guide: Running Apex as Another User, Option D: Set the created date of a record using a system method, System fields like CreatedDate are not writeable in Apex tests., Reference:, "You can’t set values for fields that have the Createable attribute set to false, such as system fields like CreatedDate or LastModifiedDate."— Apex Developer Guide: DML Statements, ]
