20+ practice questions focused on Testing Debugging And Deployment — one of the most tested topics on the Salesforce Certified Platform Developer I (SALESFORCE-PD1) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Testing Debugging And Deployment PracticeA developer wants to view real-time debug log streaming in their local environment using the Salesforce CLI. Which command should the developer execute?
Explanation: The sf apex log tail command streams debug logs to the terminal in real time.
A developer has written a test method that requires a large volume of test data to be set up. To avoid writing duplicate data setup code across multiple test methods in the same class, which annotation should the developer use?
Explanation: The @TestSetup annotation is the correct choice because it allows for the creation of test data once per test class, which is then available to all test methods in that class. The provided explanation incorrectly discusses @TestVisible instead of @TestSetup.
A developer needs to write a unit test to verify that a trigger correctly inserts related Task records when a custom object record is created. Which annotation should the developer place on the test class method to ensure it runs correctly and can access existing org data if needed?
Explanation: The @isTest annotation identifies a method or class as containing unit tests. Using @isTest(SeeAllData=true) is sometimes required when legacy data must be accessed, though best practice is to create test data locally.
A developer is preparing to deploy metadata changes from a sandbox to a production org using Outbound Change Sets. Where must the administrator or developer establish the connection between the two organizations?
Explanation: Deployment connections for change sets must be authorized and configured in Deployment Settings in the target production org.
A developer runs unit tests in the Developer Console and notices that one test method fails when run as part of the entire test class, but passes successfully when run in isolation. What is the most likely cause of this issue?
Explanation: When tests run together in a class, they share the same transaction context and any data created by one test method can leak into another unless isolated. If one test method modifies or deletes records that another test method depends on—without using Test.startTest/stopTest or proper data setup—the dependent test fails in the full run but passes in isolation because the polluting test never executed. This is classic test data pollution.
