Simplified Guide To Debugging In Salesforce

Debugging is a critical skill for anyone working in Salesforce. It helps identify and resolve issues in various components like Apex classes, triggers, Flows, Lightning Web Components (LWC), Visualforce (VF) pages, and more. In this concise guide, we’ll explore essential debugging techniques for Salesforce.

Debugging in Salesforce

1. Apex Code Debugging

System.debug(): Use System.debug() statements to log information and variables in Apex code. View logs in the Developer Console or Debug Logs.
Developer Console: This tool allows you to run code and view debug logs. It’s handy for real-time debugging.

2. Trigger Debugging

Trigger Context Variables: Leverage Trigger.new, Trigger.old, and Trigger.isUpdate to examine record changes in triggers.
System.debug() in Triggers: Insert System.debug() statements strategically within triggers to log relevant data.

3. Flow Debugging

Debug Mode: Enable “Debug Mode” while designing flows to see variable values and flow elements during runtime.
Screen Elements: Use Screen elements with dynamic choices to display variable values for debugging.

4. Lightning Web Component (LWC) Debugging

LWC Inspector: The LWC Inspector Chrome extension provides a visual tree of components, data, and events for debugging.
JavaScript Console: Utilize the browser’s JavaScript console for logging messages and identifying errors.

5. Visualforce (VF) Page Debugging

Apex Debug Logs: Debug logs capture VF page execution details. Include System.debug() statements in Apex controllers.
Browser Developer Tools: Use browser developer tools to inspect JavaScript errors and log messages for client-side debugging in VF pages.

Best Practices for Debugging in Salesforce

Use Debug Statements Sparingly: Limit the use of System.debug() to avoid cluttering code.
Check Debug Logs: Always review debug logs for error details and execution flow.
Leverage Developer Tools: Learn to use browser developer tools for client-side debugging.
Isolate Issues: Break complex problems into smaller test cases to pinpoint the root cause.
Documentation: Maintain clear code comments and variable names to aid understanding.
Ask for Help: Seek assistance from Salesforce communities or colleagues when stuck.
Version Control: Use version control systems like Git for code management.
