Scale Test FAQ
Get answers to common questions about using Scale Test.
What is Scale Test and how does it differ from traditional performance testing tools?
Scale Test is a tool designed exclusively for Salesforce that enhances your sandbox infrastructure to a production-scale configuration, allowing you to test the performance of your Salesforce org under heavy load. Unlike traditional tools like JMeter or LoadRunner, which only generate load against existing environments, Scale Test actually scales your sandbox to a production-like configuration.
What types of performance tests does Scale Test support?
Scale Test supports all major performance tests, including load, stress, endurance, and spike testing. The tool handles up to 26,000 Transactions Per Second (TPS) in Hyperforce environments and scales beyond 4,500 Requests Per Second (RPS) based on customer requirements.
How quickly can I set up and run my first performance test?
Scale Test simplifies the setup process, allowing developers and architects to schedule tests in minutes. It includes a Test Script Builder for recording user journeys that auto-generates Playwright TypeScript scripts, making it easier to test Lightning components without extensive customization.
How does Scale Test simulate real-world user interactions?
Scale Test offers a Test Script Builder for UI journey recording and supports both Playwright (frontend) and JMeter (API-heavy) workloads. It also includes AI-powered script healing to fix common script issues and build complex workloads.
How do I calculate my Requests Per Second (RPS)?
Visit the Org Performance page in Scale Center. View the Request Volume/10 min graph, and then divide it by 600 to convert it to requests per second. If you don't have any production volume, run a small test with 10 or 20 users on your sandbox and review the graph in Scale Center.
What cloud products does Scale Test scale up to a production-like level?
Scale Test supports Sales Cloud, Service Cloud, Community Cloud, and Experience Cloud.
What performance metrics and reports are available?
Scale Test provides live client-side metrics and can differentiate between Lightning rendering and Salesforce backend performance. It includes a Test Plan Creation report that identifies scale hotspots, live observability with metrics, logs, errors, and screenshots, and integration with Scale Center for detailed investigations.
How long is my test data retained?
You can retrieve Test Plan Creation reports from the last 30 days and Trial Accuracy reports from the last 15 days.
Does Scale Test impact org performance or access my data?
No, the logs collected by Scale Test have no impact on your org's performance. Scale Test only accesses observability data collected from execution and doesn’t access your data.
How is Scale Test licensed and booked?
Scale Test is a standalone SKU priced per day, with each day providing 24 hours of enhanced, production-like sandbox infrastructure. A Scale Test day begins at 00:00 and ends at 23:59 local organization time, as configured in your Setup. New bookings require two weeks of notice. Choose a point of contact with access to the Scale Test features. That person receives email reminders and in-app notifications about upcoming activities.
Why are there unavailable scale test days on my calendar?
Another customer in your instance could be testing on those days, or they were blocked for internal reasons.
What should I do if my sandbox is refreshed or deleted?
If you refresh or delete a sandbox, you must cancel any booked Scale Test days to avoid being charged. Cancellations require at least one week of notice. If the test environment upgrade validation fails for a particular scale test day, you can request an additional test from your Salesforce account executive. Bookings are for a specific 24-hour window and can't be extended. You must adhere to the confirmed schedule. If you test beyond that, Salesforce reserves the right to stop your test.
Can minor sandbox releases impact scale tests?
Yes, minor sandbox releases are normal and can occur during scale tests. We can’t prevent them, but you can run your test again to mitigate the impact, especially for standard 24-hour tests. To help us investigate performance issues, provide the request duration, normal response times, and details about the affected requests.
What happens if I exceed my booked RPS or if Salesforce cancels my test?
You must provide your expected maximum RPS when booking your test. If you test beyond that, or if your test causes issues in the overall instance, Salesforce reserves the right to stop it. If Salesforce cancels your test day, you receive at least 12 hours of notice, won't be charged for that day, and can book the next available slot. Contact your account executive.
How do I get access to Scale Test features?
A system admin can assign you to either the
ScaleTestingServiceStandardUserPS (basic access without Test
Scheduler) or the ScaleTestingServiceAdvancedUserPS permission set (full access). Also,

refresh.
