# Introducing test mode for clearinghouse transactions

> In test mode, you can submit mock real-time eligibility checks and Stedi sends back a realistic benefits response so you know what to expect.

Product: Eligibility checks

Test mode provides a separate test environment where you can simulate transactions in your Stedi account without PHI/PII and without sending any data to payers.

In test mode, you can submit mock real-time eligibility checks and Stedi sends back a realistic benefits response so you know what kinds of data to expect in production. You can send mock requests for a variety of well-known payers, including:

- Aetna

- Cigna

- UnitedHealthcare

- National Centers for Medicare & Medicaid Services (CMS)

- Many more - Visit [Eligibility mock requests](https://www.stedi.com/docs/healthcare/api-reference/mock-requests-eligibility-checks) for a complete list

After you submit a mock eligibility check, you can review all of the request and response details in the [Stedi portal](https://www.stedi.com/docs/healthcare/eligibility-views). This includes a user-friendly benefits view designed to help you quickly understand the patient’s active coverage and payment responsibilities.

To access test mode in your account, toggle **Test mode** to **ON**. Visit the [test mode docs](https://www.stedi.com/docs/healthcare/test-mode) for more details.
