Universal Containers has developed custom Apex code for their organization. What are two factors that the developer must take into account to properly deploy the modification to the production environment? (Choose two.)

A. Apex classes must have at least 75% code coverage org-wide
B. At least one line of code must be executed for the Apex trigger
C. All methods in the test classes must use @isTest
D. Test methods must be declared with the testMethod keyword

Correct Answers: A and B

Explanation:
Salesforce requires 75% org-wide code coverage for production deployment, and every Apex trigger must have at least one line executed by tests (even if that trigger has no executable code beyond the trigger definition).

Code Coverage Requirements:

• Minimum for deployment: 75% org-wide
• Best practice target: 85%+ per class
• Triggers: At least one line must execute
• Test methods: Do NOT count toward coverage percentage

Test Class Structure:

@isTest
private class AccountTriggerTest {
    
    @TestSetup
    static void setupTestData() {
        // Create test data here
        List<Account> testAccounts = new List<Account>();
        for(Integer i = 0; i < 200; i++) {
            testAccounts.add(new Account(Name = 'Test Account ' + i));
        }
        insert testAccounts;
    }
    
    @isTest
    static void testAccountTrigger() {
        // Your test logic
        Test.startTest();
        List<Account> accounts = [SELECT Id, Name FROM Account];
        for(Account acc : accounts) {
            acc.Name = acc.Name + ' Updated';
        }
        update accounts;
        Test.stopTest();
        
        // Assertions
        System.assertEquals(200, [SELECT COUNT() FROM Account]);
    }
}

Why other options are incorrect:

• Option C: While @isTest is recommended, testMethod keyword still works (legacy)
• Option D: Both @isTest annotation and testMethod keyword are valid
