Developers CRT-450 Reddit Questions

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.

A. 75% Test Coverage:Salesforce mandates that 75% of all Apex code must be covered by tests to be deployable to production.

D. Trigger Coverage:Each Apex trigger must have at least one line of test coverage to ensure it is properly tested.

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

Declaring the constant asstaticensures it is shared across all instances of the class.

Declaring it asfinalensures its value cannot be modified after initialization.
