Which action is typically included in Apex tests?

Mocking HTTP requests is a crucial action included in Apex tests. In Apex, tests are designed to ensure that code behaves as expected under various conditions, including those where external services are involved. By mocking HTTP requests, developers can simulate interactions with external APIs without actually making outbound calls. This is important because it eliminates the possibility of errors that could occur due to network issues, rate limits, or changes in the external service being tested.

Mocking allows the developer to define specific responses for the requests that the code makes, thus enabling the testing of different scenarios like success responses, error messages, or timeouts. This controlled environment is essential to ensure that the business logic works as intended regardless of the actual state or behavior of the external service at the time of the test.

Other actions listed, such as generating a report, verifying user roles, and testing submission forms, do not directly pertain to the typical methods employed in Apex testing to handle external resources. While they could be part of broader functional tests or used in other aspects of Salesforce development, they do not represent the key strategy for isolating and testing code that interacts with HTTP requests.
