Top Entry-Level Salesforce Testing Interview Questions

Below is a carefully selected list of the most commonly asked questions for entry-level roles or the initial rounds of Salesforce QA interviews. These questions focus purely on domain knowledge and real-world testing scenarios.

1. What is Salesforce testing, based on your understanding? Why is it important in real-world projects?

Answer: Salesforce testing ensures that custom configurations, code, and integrations work as intended across roles and workflows. It helps prevent automation failures, data issues, and system errors. By validating functionality, performance, and security, Salesforce testing safeguards business operations, customer experience, and compliance in real-world CRM environments.

2. How do you differentiate functional and non-functional testing?

Answer: Functional testing validates that system features like workflows, validation rules, and permissions behave as expected. Common types include unit testing, integration testing, and UAT.

Non-functional testing evaluates performance, security, and usability.

Example: Testing the lead conversion functionally ensures proper object creation; non-functionally, it checks speed and data protection under load.

3. How does testing ensure that real-world business workflows function accurately in Salesforce?

Answer: Testing in Salesforce ensures business workflows run accurately by verifying that every component, from custom features to integrations, behaves as intended. Through functional testing, UAT, regression checks, and security validation, we catch issues early and make sure the system supports real-world processes without disruptions.

4. Which tools can be used for manual testing in Salesforce? Have you worked with any of them?

Answer: For manual testing in Salesforce, tools like JIRA and Zephyr are used for test case and defect management, while Postman helps with manual API testing. Testers also use Salesforce’s UI, Setup menu, and Debug Logs to validate workflows.

5. What is the minimum Apex test coverage required before code can be deployed to production?

Answer: The minimum Apex test coverage required to deploy code to production in Salesforce is 75%. 

6. You’ve configured a workflow rule. How would you test whether it executes as expected?

Answer: To test a workflow rule, I create or update a record that matches the rule criteria and verify if the expected actions, such as field updates, email alerts, or tasks, are triggered. Debug logs and the Setup Audit Trail help confirm that the rule executed as expected.

7. How do you verify data integrity during Salesforce testing?

Answer: Data integrity is verified by ensuring that data remains accurate, complete, consistent, and valid throughout the system. This involves validating input fields, checking for duplicate or missing records, and confirming adherence to defined formats and business rules using validation rules, test scripts, and monitoring tools

8. What are your steps to ensure field-level security is properly applied during testing?

Answer: To ensure field-level security (FLS) in Salesforce, I review FLS settings in Setup, test with different user profiles, verify field access via UI, reports, and APIs, and use Schema.DescribeFieldResult in Apex tests. Post-deployment, I validate integrations and document results to ensure compliance with security and data integrity policies.

9. A user reports they can’t see a field on the layout. How would you investigate and test this?

Answer: I’d verify Field-Level Security (FLS) for their profile and check if the field is on their assigned page layout. Then, I’d test via ‘Login As’ to confirm visibility issues, inspect record-type assignments, and check for conditional visibility rules. Finally, I’d validate in different contexts (mobile, reports) to isolate the root cause

10. What is your approach to testing a newly added custom field in an existing object?

Answer:  It starts by checking Field-Level Security (FLS) for the user’s profile, following by confirming the field included in the assigned page layout. I’d use ‘Login As’ to replicate the issue, inspect record type conditions, and test across contexts like mobile and reports to identify the exact cause.

Mid-Level Salesforce testing interview questions

1. What is a Salesforce Sandbox, and how does each type support different stages of testing?

Answer: A Salesforce Sandbox is a test environment of your production org used for development, testing, and training. It allows teams to validate changes safely without impacting live data or users. Each sandbox type supports different phases of the testing lifecycle from basic unit testing to full-scale UAT. Here’s a quick breakdown:

2. How do governor limits influence how you design or execute your Salesforce test cases?

Answer: Governor limits in Salesforce exist to ensure fair and efficient use of shared system resources. These limits control things like how many SOQL queries or DML statements can be executed in a single transaction. When designing test cases, it’s crucial to keep these boundaries in mind, especially while testing bulk operations, complex triggers, or integrations. Test scenarios must mimic real-world usage but remain efficient, ensuring that the code performs reliably without exceeding system thresholds. This helps maintain both performance and deployment readiness.

3. Walk me through a Salesforce approval process you’ve tested. What were the key test cases and validations involved?

Answer: An approval process in Salesforce routes a record through defined stages based on conditions. While testing it, key checks include:

• Entry criteria triggering the process correctly
• Approvers assigned as per hierarchy or role
• Fields locking during the process
• Rejection/resubmission flows working as intended
• Notifications and email alerts triggering properly
• Final status updates and any post-approval actions (like field updates or tasks)

Each test ensures the process reflects actual business logic without failures.

Interview Tip:
When answering questions about approval processes, don’t just explain the steps — tie each test case back to a real business rule. For example, say “I verified that only managers could approve expenses above ₹50,000” instead of just “I tested approval levels.” This shows you understand the business impact, not just the technical flow.

4. What’s your approach to exploratory testing in Salesforce? Can you give a real scenario where it uncovered a hidden issue?

Answer: Exploratory testing in Salesforce means navigating the app like a real user to uncover issues beyond scripted tests. I focus on unexpected behaviors in workflows, permissions, and UI elements, especially across different profiles. This helps catch hidden bugs that formal test cases often overlook.

Interview Tip:
When sharing an example, highlight what triggered your curiosity, the issue you uncovered, and why it mattered. For instance:

“While testing lead conversion with different profiles, I noticed some users could skip mandatory fields. This revealed a gap in validation logic tied to profile permissions, something scripted tests didn’t account for.”

This approach shows critical thinking, awareness of role-based behavior, and a real QA mindset.

5. How do you ensure consistent test coverage and quality in a rapidly changing Salesforce environment?

Answer: By maintaining a stable regression suite, reviewing changes closely with devs/admins, using sandbox testing, updating test cases regularly, and automating repeatable flows.

6. How would you validate that role-based access and sharing settings are correctly configured for a custom object?

Answer: Validating starts by reviewing profile and permission set access, checking org-wide defaults, evaluating sharing rules, and confirming visibility across roles using test records.

7. What’s your process for testing integrations, for example, a third-party ERP system connected via REST API?

Answer: The most common process includes validating request/response payloads, checking authentication flows, simulating API failures, verifying data mapping, and ensuring accurate data sync across systems.

8. How do you approach regression testing when multiple workflows, flows, and Apex triggers are updated in the same sprint?

Answer:  Start by identifying impacted areas, prioritize business-critical flows, run the regression suite, retest automation and triggers, and validate end-to-end scenarios to catch conflicts or breakages.

9. A critical bug made it to UAT. How would you analyze what went wrong and prevent it in the future?

Answer: 

• Reproduce the Bug – Confirm the issue and understand the conditions under which it occurs.
• Check Test Coverage – Review test cases to see if this scenario was missed or poorly covered.
• Analyze Root Cause – Identify if the issue came from miscommunication, incomplete requirements, or missed validation.
• Review Change Logs – Check recent deployments, config changes, or code commits.
• Collaborate with Dev/Admins – Discuss findings to pinpoint gaps in development or testing.
• Update Test Cases – Add or revise test cases to cover the missed scenario.
• Prevent Recurrence – Conduct a team review, improve checklists, and refine QA processes for future sprints.

10. Can you explain the difference between testing in Classic vs Lightning Experience? What UI or functional nuances should QA watch for?

Answer: Testing in Lightning focuses more on dynamic UI components, conditional visibility, and performance, whereas Classic is mostly static. Lightning requires checks for responsive design, LWC behavior, and event handling.

• First, replicate the issue using the same profile and record type.
• Review the validation rule logic, especially if it’s using ISBLANK, ISPICKVAL, or custom fields.
• Check if the rule incorrectly assumes default values or missing conditions.
• Use debug logs to see which condition is failing during the save action.
• Collaborate with the admin/dev team to fix the logic or add exceptions.

2.  After a new deployment, email notifications stopped for a critical approval process. What would you do?

Answer:

• Verify if the email template or workflow rule was modified in the deployment.
• Check the approval process configuration. Are email alerts still attached?
• Review user email deliverability settings and org-wide email addresses.
• Test email logs and use “Send Test and Verify Merge Fields” to debug templates.

3. A third-party API integrated with Salesforce is returning inconsistent data. Where do you begin testing?

Answer:

• Begin by capturing request/response pairs in tools like Postman or using debug logs.
• Validate whether the issue is data-related (e.g., mapping errors) or logic-based.
• Check for recent changes to API endpoints, authentication, or field-level changes.
• Simulate API calls in a sandbox to isolate the issue from production noise.
• Review error handling logic and implement fallback/error logs if missing.

4.  A lead converted to an opportunity is missing related contact data. What could be the root cause?

Answer:

• Reproduce the conversion using different test leads.
• Check lead mapping settings in Setup, especially for standard/custom fields.
• Validate triggers or flows that might interfere during conversion.
• Confirm whether contact creation was skipped or overwritten post-conversion.
• Review Apex logic or integration scripts tied to lead conversion events.

5. Your automation script fails randomly when testing Lightning components. How do you ensure stability?

Answer:

• Identify if failures are tied to dynamic components or loading delays.
• Use explicit waits (e.g., WebDriverWait) instead of hard-coded sleep.
• Validate Lightning selectors are robust (avoid brittle XPaths).
