NEW QUESTION # 158
While writing an Apex class, a developer wants to make sure that all functionality being developed is handled as specified by the requirements.
Which approach should the developer use to be sure that the Apex class is working according to specifications?

A. Run the code in an Execute Anonymous block in the Developer Console.
B. Include a try/catch block to the Apex class.
C. Include a savepoint and Database.rollback().
D. Create a test class to execute the business logic and run the test in the Developer Console.

Answer: D

Explanation:
To ensure that the Apex class is functioning according to the specified requirements, the developer should write a test class that executes the business logic and verifies that it behaves as expected.
Option A: Create a test class to execute the business logic and run the test in the Developer Console.
Correct Approach.
Writing a test class allows the developer to create unit tests that verify the functionality of the Apex class.
Test methods can assert that the class behaves as intended under various conditions, ensuring compliance with requirements.
Running the test in the Developer Console allows the developer to see the results and debug if necessary.
Benefits:
Automated Testing: Ensures repeatability and consistency in testing.
Code Coverage: Helps achieve required code coverage for deployment.
Regression Testing: Facilitates detection of future changes that might break existing functionality.
While running code in Execute Anonymous allows for quick tests, it is not suitable for thorough testing.
It doesn't provide assertions to verify that the output matches expected results.
Tests run in Execute Anonymous are not saved and cannot be rerun easily for regression testing.
Using savepoints and rollbacks can help in testing DML operations without committing changes to the database.
However, this doesn't ensure that the class meets the functional requirements.
Adding try/catch blocks can handle exceptions but does not verify that the class functions as specified.
Exception handling is a part of robust code but doesn't replace the need for testing.
Reference:

Option D: Include a try/catch block to the Apex class.

Conclusion:
Writing a test class is the best way to ensure that the Apex class works according to the specifications.
Test classes allow for comprehensive testing with assertions, providing confidence that the code meets the requirements.
