After running all tests, theOverall Code Coverage panelin the Developer Console shows the code coverage percentage for each class.

This is the most reliable and optimal way to view code coverage.

Checking Code Coverage

Maximum Trigger Depth Exceeded:

This error occurs when a trigger causes recursive calls, leading to an infinite loop of execution.

Solution:

Use static variables in helper classes to prevent recursive trigger execution.

Example:

public class TriggerHelper {

public static Boolean isTriggerExecuted = false;

}

trigger AccountTrigger on Account (after update) {

if (!TriggerHelper.isTriggerExecuted) {

TriggerHelper.isTriggerExecuted = true;

// Trigger logic here

}

}

Why Not Other Options?

A: Permissions do not affect trigger recursion.

B: Length of the trigger is unrelated to recursion.

C: Code coverage does not influence runtime errors like recursion.

Why Controller?

A customcontrollerallows:

Complex validation involving multiple objects.

Redirection to another Visualforce page upon success.

Controllers can implement custom save logic and redirect usingPageReference.

Why Not Other Options?

A. Apex: Apex is the underlying programming language, but a controller specifically handles the Visualforce logic.

B. Trigger: Triggers execute on DML events, not on button clicks in Visualforce.

D. Extension: Extensions enhance standard controllers but are not necessary here since a custom controller is being built.
