19 Salesforce Testing Interview Questions for Job Success

1. Core knowledge of Salesforce testing
Q1. What is Salesforce testing and how does it differ from testing of other web applications?
Salesforce Testing ensures that everything, from features to customizations in the Salesforce platform, works the way it is supposed to. Unlike most web applications, Salesforce has dynamic elements such as workflows, triggers, Visualforce pages, and Lightning components. Moreover, Salesforce also has its own restriction rules known as Governor Limits, which add even more constraints on how much data or processing you can handle at once. Therefore, tests need to consider these limits to avoid errors.

Q2. What are the types of testing that you have performed while using Salesforce?
• Functional Testing: Testing the app to check whether it is working according to the needs of the business.
• Integration Testing: Whether Salesforce integrates well with other systems or not.
• System Testing: The testing of the whole system end-to-end for any problems.
• User Acceptance Testing: Whether everything works well for real users and helps achieve business goals.

Q3. List the challenges that you faced while testing on Salesforce and how you overcame these challenges.
Salesforce Testing involves dealing with dynamic page elements, constant updates, and Governor Limits. Here is how I manage issues:
• Use dynamic locators in automation scripts when the element location is dynamic.
• Keep track of every Salesforce release to be well-prepared for unexpected scenarios.
• Make sure that governor limits are taken into consideration.

Q4. What are governor limits, and why do these matter in testing?
Governor Limits: think of them as Salesforce’s defense mechanism against overusing or exploiting one’s Salesforce resources.

2. Automation Testing on Salesforce
Q5. Which Salesforce automation tools have you used? What are the benefits of each?
Selenium: Open source, flexible & friendly with UI testing.
Provar: Developed for Salesforce, easy-to-manage test cases.
TestNG: Provides very detailed reports and is well-organized in accordance with the test case. Tests are executed much faster. The extent of errors decreases with the increase in coverage.

Q6. How do I build tests for Lightning versus Classic components?
Lightning components are a bit more complex because they use dynamic HTML and Shadow DOM. To handle this, tools like Selenium 4 are required, and sometimes the JavaScriptExecutor is needed to handle those elements that are hard to interact with.

Q7. What is one Salesforce process you automated most? How did it help?
I automated the lead conversion process using Selenium and TestNG. It would take 3 hours to complete the task manually; it takes just 30 minutes when automation tools are used. We could also run tests after every new release without putting in any extra effort.

3. Test Scenarios and Test Cases
Q8. How do you design test cases for Salesforce objects?
• Identify key fields, relationships, and validations.
• Test cases for simple operations like create, update, and delete.
• Positive tests (what should work) and negative tests (what should not work).

Q9. Describe a challenging Salesforce testing scenario you have encountered.
I once tried to test a pretty complex approval workflow for opportunities. Here’s how I went about it:
• Developed multiple test data for each step of the approval process.
• verified what happened at each stage.
• I automated the process, which involved verifying emails and the updation of records.

Q10. How would you make Salesforce accommodate dynamic items and changeable requirements?
• Apply dynamic locators as well as flexible XPath techniques.
• Utilize the Page Object Model (POM) for the tests to be neatly maintained and easy to update.
• Review and update test cases regularly to keep up with changing business needs.

4. Apex Testing
Q11. What is an Apex Test Class, and how would you write one?
It would notify you if your Apex code worked the way it should. Deploying code on Salesforce requires at least 75% code coverage. Here’s an easy example:

apex
@isTest
public class SampleTestClass {
@isTest static void testMethod() {
Account acc = new Account(Name = ‘Test Account’);
insert ACC;
System.assertEquals(‘Test Account’, acc.Name);
}
}

Q12. How would you know you have sufficiently tested all code of a given Apex class?
You have to write test methods that should cover good inputs, bad inputs, and edge cases. To deploy the code in Salesforce, you need at least 75% code coverage.

Q13. What is the difference between positive and negative test cases for an Apex trigger?
• Positive test cases: Test what the code will do when given good inputs.
• Negative test cases: Try checking if the code will work with invalid inputs, null values, or missing data.

5. Data validation and security testing
Q14. How would you test data integrity in Salesforce testing?
• It does not change in objects.
• Validate field-level validations as well as relationships.
• Any operations or integrations should not result in data corruption.

Q15. What will be the validation methods of Salesforce role-based security?
• Develop different roles and user profiles.
• Check who is seeing what user information or performing actions.
• Test permission sets and sharing rules to ensure that access is correctly configured.

Q16. How do you test data migration in Salesforce?
• Pre-migration: Confirm that the mapping is properly backed up.
• Use the utility of data loader for data migration.
• Post-migration: check whether everything is okay or not using SOQL queries

6. Integrations and APIs
Q17. How would you test the integration of Salesforce with third-party systems?
• Verify the Request and Response Payload
• Test error handling and the capability of the system (to timeout).
• Third-party tools such as Postman and SoapUI may also be used.

Q18. What problems did you face while testing the APIs and how did you resolve them?
• Authentication problems: OAuth 2.0.
• Rate limits: Maintain a track record of API usage.
• Data consistency: Test in a sandbox environment before implementation.

7. Performance and Regression Testing
Q19. How would you test the performance of Salesforce?
I would test its loading with tools such as JMeter, simulate its working with high loads, and then check for response times. Recently, for example, I optimized nested SOQLs and added indexes to correct a slow query.
