Question # 49

A developer creates a new Apex trigger with a helper class, and writes a test class that only exercises 95% coverage of the new Apex helper class.

Change Set deployment to production fails with the test coverage warning:

"Test coverage of selected Apex Trigger is 0%, at least 1% test coverage is required."

What should the developer do to successfully deploy the new Apex trigger and helper class?

Create a test class and methods to cover the Apex trigger.

Question # 50

A developer is alerted to an Issue with a custom Apex trigger that is causing records to be duplicated.

What is the most appropriate debugging approach to troubleshoot the issue?

Add system.debug statements to the code to track the execution flow and identify the issue.

Use the Apex Interactive Debugger to step through the code and identify the issue.

Disable the trigger in production and test to see if the issue still occurs.

Review the Historical Event legs to identify the source of the issue.

Answer:

Explanation:

When a developer is alerted to an issue with a custom Apex trigger causing records to be duplicated, the most appropriate debugging approach is to add System.debug statements to the code.

Option A: Add System.debug statements to the code to track the execution flow and identify the issue

Trace Execution Flow: System.debug statements help log the values of variables and the execution path.

Identify Logic Errors: By examining the debug logs, the developer can pinpoint where the duplication is occurring.

Minimal Impact: Adding debug statements is a minimal code change and does not alter the functionality.

[:, Debugging with System.debug, Best Practices for Debugging, Why Other Options are Less Optimal or Incorrect:, Option B: Use the Apex Interactive Debugger to step through the code, Limited Availability: The Apex Interactive Debugger is not typically available in production environments., Requires Setup: Needs special permissions and setup, which may not be feasible., Reference: Apex Debugger, Option C: Disable the trigger in production and test to see if the issue still occurs, Risky: Disabling the trigger can disrupt business processes and data integrity., Not a Debugging Strategy: Does not help identify the cause within the code., Reference: Managing Apex Triggers, Option D: Review the Historical Event Logs to identify the source of the issue, Insufficient Detail: Event logs may not provide the necessary detail about code execution to identify the issue., Better for Auditing: More suited for tracking user actions rather than debugging code., Reference: Event Monitoring, Conclusion:, Adding System.debug statements and reviewing the resulting debug logs is the most appropriate and effective method to troubleshoot and identify the issue causing record duplication., It allows the developer to understand the code execution flow and make necessary corrections., ]
