NEW QUESTION # 44
Refer to the test method below:
The test method calls an @future method that increments the Number_of_Times_Viewed__c value. The assertion is failing because the Number of Times Viewed_c equals 0. What is the optimal way to fix this?
Answer: C
Explanation:
When a test method calls an @future method that performs DML operations, the changes made by the @future method won't be visible until after the Test.stopTest() is called. This method ensures that all asynchronous processes are completed before the test execution continues. Therefore, Test.startTest() should be before the call to the @future method and Test.stopTest() immediately after.
