Salesforce Certified Platform Developer I Sample Questions (Q95-Q100):

NEW QUESTION # 95
A developer needs to create a baseline set of data (Accounts, Contacts, Products, Assets) for an entire suite of tests allowing them to test independent requirements for various types of Salesforce Cases.
Which approach can efficiently generate the required data for each unit test?

A. Create a mock using the Stub API.
B. Add @TsTest (seeAllData=true) at the start of the unit test class.
C. Use @TestSetup with a void method.
D. Create test data before Test.startTest {} in the unit test,

Answer: C

Explanation:
To efficiently generate a baseline set of data for unit tests that can be shared across multiple test methods, you should:
Option A: Use @TestSetup with a void method.
@TestSetup Annotation:
The @TestSetup method runs once before any test methods in the test class and is used to create common test data.
Data created in @TestSetup is available to all test methods within the test class.
Example:
@IsTest
private class MyTestClass {
@TestSetup
static void setupData() {
// Create Accounts, Contacts, Products, Assets
// This data is available to all test methods
}
@IsTest
static void testCase1() {
// Test logic here
}
@IsTest
static void testCase2() {
// Test logic here
}
}
Reference:
"Use test setup methods (methods that are annotated with @TestSetup) to create test records once and then access them in every test method in the test class."
- Apex Developer Guide: Using Test Setup Methods
Why Other Options Are Less Efficient:
Option B: Create test data before Test.startTest() in the unit test.
This approach would require creating test data in each test method, leading to code duplication.
Option C: Add @IsTest(seeAllData=true) at the start of the unit test class.
Using seeAllData=true is discouraged as it makes tests dependent on org data, which can lead to unreliable tests.
Option D: Create a mock using the Stub API.
The Stub API is used for mocking interfaces and not for creating test data.
Conclusion:
Using @TestSetup methods is the most efficient way to generate required test data for unit tests.

NEW QUESTION # 96
When using SalesforceDX, what does a developer need to enable to create and manage scratch orgs?

A. Production
B. Environment Hub
C. Sandbox
D. Dev Hub

Answer: D

Explanation:
A scratch org is a temporary Salesforce instance, typically used for a specific development. To create and manage scratch orgs, a developer needs to enable the Dev Hub feature in a Salesforce org. The Dev Hub org acts as a central hub for creating and tracking scratch orgs. The Dev Hub org can be a production org, a developer edition org, or a business org. The Dev Hub feature is not available in sandboxes or environment hubs. References: Scratch Orgs | Salesforce DX Developer Guide, Get Started With Salesforce Scratch Orgs

Option A: Overwriting old values happens after loading the record.

Option C: System validation for field lengths happens after loading the record.
Reference:
Order of Execution:
