• Set up the required test data.
• Perform DML operations such as insert, update, delete, or undelete to fire the trigger.
• Use System.assert() statements to verify that the trigger executed correctly and produced the expected results.

Example:

@isTest
public class TriggerTestClass {

    @isTest
    static void testAccountTrigger() {

        // Create test data
        Account testAccount = new Account(Name='Test Account');
        insert testAccount;

        // Execute trigger
        testAccount.Name = 'Updated Test Account';
        update testAccount;

        // Verify results
        Account updatedAcc = [SELECT Name FROM Account WHERE Id = :testAccount.Id];
        System.assertEquals('Updated Test Account', updatedAcc.Name);
    }
}

This ensures the trigger works correctly and provides the required code coverage for deployment.

26. What is a Mock Object in Salesforce Testing?

A Mock Object in Salesforce Testing is a simulated object that mimics the behavior of real objects in controlled ways.
