Question 1

Which Salesforce tool allows developers to run Apex tests directly from the command line as part of a CI/CD pipeline?

Accepted Answer

Salesforce DX CLI (sf apex run test)

Answer

The Salesforce CLI command `sf apex run test` enables automated test execution in CI/CD pipelines without a UI.

Question 2

What does the `@testSetup` annotation do in an Apex test class?

Accepted Answer

Creates test data once before all test methods run, rolling back after each method

Answer

`@testSetup` runs once to create shared test data that is rolled back and recreated for each individual test method, improving performance.

Question 3

A developer wants to confirm that a trigger correctly prevents duplicate Account records. Which assertion is most appropriate?

Accepted Answer

Try/catch block catching DmlException and asserting the error message

Answer

Using a try/catch block to catch the DmlException and asserting the error message confirms the trigger throws the correct exception for duplicates.

Question 4

What is the recommended approach when a test method needs to call an external web service?

Accepted Answer

Use Test.setMock() with an HttpCalloutMock implementation

Answer

`Test.setMock()` with `HttpCalloutMock` provides a simulated HTTP response so tests can validate callout logic without real network calls.

Question 5

Which statement best describes a unit test in the context of Salesforce Apex development?

Accepted Answer

A test that validates a single method or small unit of code in isolation from dependencies

Answer

Unit tests focus on a single, isolated unit of code (method or class) and use mocks or stubs to remove external dependencies.
