Salesforce PDI - Salesforce Certified Platform Developer 1 (SP25)

Why Prebuilt Components?

The Lightning Component Framework includes a library of prebuilt components, which developers can use to build applications faster.

Why Not Other Options?

A: The framework is exclusive to Lightning Experience, not Classic UI.

C: The framework does not provide templates but focuses on reusable components.

D: Extended governor limits are not provided by the framework.

When writing test classes, accessing the Standard Price Book is essential for creatingOpportunityLineItemrecords.

The methodTest.getStandardPricebookId()is specifically designed to retrieve the Standard Price Book ID in a test class context. This ensures you can work with the price book without requiring@isTest(SeeAllData=true).

Why not other options?

B:@isTest(SeeAllData=true)is not recommended because it violates Salesforce best practices by accessing actual org data.

C:@TestVisibleis used for visibility between classes but does not relate to retrieving Standard Price Book.

D:Test.loadData()loads test data from static resources but is unnecessary for accessing the Standard Price Book.

Salesforce Testing Framework

Apex Testing Best Practices

The@TestVisibleannotation allows private methods or variables to be accessed in test classes. This ensures that the private method can be adequately tested without changing its access modifier.

A. Debug logs can be set for specific users, classes, and triggers:

Debug logs can be configured for users, classes, and triggers by setting trace flags.

C. Only the 20 most recent debug logs for a user are kept:

Salesforce retains only the 20 most recent debug logs per user. Older logs are overwritten.

E. The maximum size of a debug log is 5 MB:

Debug logs are capped at 5 MB. If this limit is exceeded, logging stops for that transaction.

Why Not B and D?

B: Debug logs are retained for7 days, not 24 hours.

D: Debug log levels are not cumulative. Each level is independent.

When working with a Lightning Web Component (LWC), the correct syntax for importing an Apex method is:import methodName from "@salesforce/apex/ControllerName.methodName";.

Why not other options?

A,B, andC: These use incorrect syntax for importing Apex methods in LWCs.

Lightning Web Components Documentation

Record-triggered flows allow automation to create tasks when an Opportunity is created. It is declarative, easy to maintain, and does not require custom code.

Steps:

Create a record-triggered flow for theOpportunityobject.

Set it to run on record creation.

Use the "Create Records" element to create a task for the Opportunity owner.

Record-Triggered Flows

Option A: Using aTest Data Factoryclass is a recommended approach to create test records programmatically. This ensures that the test is independent of existing data and can be executed in isolation.

Option B: The@IsTest(SeeAllData=true)annotation allows the test to access existing records in the database, includingPricing_Structure__c. However, this is less recommended as it creates a dependency on existing org data.

Not Suitable:

Option C:Test.loadDatais used to load records from a static resource (CSV) but doesn't suit the requirement directly.

Option D: Addingwithout sharingto a class impacts sharing rules but does not create or ensure the existence of test data.

Testing Best Practices

The code snippet in question creates and inserts an account namedMyAccountand then initializes a loop to add additional accounts.

The loop runs fromx = 1and continues adding accounts untilx < 10.

Since the conditionx++is post-increment, the loop runs exactly 10 times, creating and adding 10 new accounts to thenewAccountslist.

At the end, theinsertDML statement persists these 10 new accounts, along with the already existing account (MyAccount).

Total accounts in the org:

Existing accounts = 5

New accounts added = 10

Total = 15

Salesforce SOQL & SOSL Reference

75% Code Coverage (A):To deploy Apex code to production, Salesforce requires at least 75% of the code to be covered by tests across the organization.

Why These Settings?

bubbles: true: Enables the event to propagate up the containment hierarchy.

composed: true: Allows the event to cross the Shadow DOM boundary.

Why Not Other Options?

Other combinations (e.g.,bubbles: false) prevent the event from propagating or crossing the Shadow DOM boundary.
