Which of the following statements about ATF tests and suites is true regarding their default behavior and environment?

• A. They should be run in non-production instances
• B. They can run in production without restrictions
• C. They must be run only in UAT
• D. They are deprecated and should not be used

Answer: (A)

ATF tests are designed to validate changes without impacting live users, so they are typically run in non-production instances. This keeps test activity isolated from production data and performance, allowing you to seed test data, reset environments, and observe results safely. Running automated tests in production without restrictions would risk end users and data integrity, which is why production isn’t the defaultplace for ATF execution. Limiting ATF runs to only a UAT environment is too restrictive since these tests are useful across development, QA, and UAT in non-production settings. And ATF is not deprecated—it's a supported tool for automating regression tests in ServiceNow.
