# Run passive mode sender tests

This tutorial demonstrates how use Test Harness to receive and process a single payment from the RippleNet Server UI.

1. To run sender tests, log on to a Test Harness that receives payments.
2. On the **Passive Mode** tab, enable **Auto Lock Accepted Quotes** and **Auto Complete Payments**. Leave **RPO Schema** as `none`.


<!-- -->
To test against an RPO schema, upload one in **Test Content**.

1. If a test is `OPEN`, click **Close Test**.
2. In the RippleNet Server UI, click **Create Payment** or use your own payment application.
3. Enter payment details:
  * Quote Type: Sender Amount
  * Currency: USD
  * Amount: 501
  * Sender Account: (for example, `trans_usd_rn_sender`)
  * End-to-end ID: (Any value such a randomly generated UUID)
  * Internal ID: 001
  * Receiver Host: (for example, `dev.rn_receiver`)
  * Receiver Account: (for example, `trans_usd_rn_receiver`)
  * Payout Method: Default
4. Click **Get Quote**, select the quote, and then click **Select quote and continue** > **Save**.
At this step, *if* an active mode test were open, and *if* you added Additional Information (`user_info`) with a test case ID that matched one in the active mode test profile, you would trigger an active mode test.
5. To view the new `OPEN` test, in the Test Harness, refresh the **Passive Mode** tab
6. Click through the **Test ID** of the `OPEN` test. Your payment should be in the `LOCKED` state.
7. In the RippleNet Server UI click **Refresh** to update the payment as **Locked**.
8. Click **Settle** > **Settle payment** to execute the payment.
9. In the Test Harness, the payment state should transition to `COMPLETED`.
10. Click **Logs** to see the messages.
