Which method is commonly used to debug a controller in Salesforce Commerce Cloud?

Using logging statements is a prevalent and effective method for debugging a controller in Salesforce Commerce Cloud. When developers implement logging within their code, they can capture crucial system events, variable values, and execution paths. This provides insight into the application's behavior while it runs, which is essential for identifying and resolving issues.

The advantage of using logging statements lies in their ability to output messages to the logs at various stages of the execution flow, allowing developers to trace operations, analyze the flow of data, and pinpoint failures or unexpected behavior. This method is particularly useful in a non-intrusive manner, as it does not require stopping the application or interrupting its normal operation.

While peer code reviews, running automated tests, and visualizing flowcharts can be valuable practices in the overall development process, they serve different purposes. Peer code reviews focus on code quality and adherence to best practices, automated tests help ensure functionality and stability, and visualizing flowcharts provides a holistic view of logic and processes. However, none of these methods provide the same level of real-time feedback and detailed insight into the execution flow as logging does, making it a preferred choice for debugging controllers in Salesforce Commerce Cloud.
