# Run passive mode receiver tests

This short tutorial demonstrates how you can use the Test Harness to send and process a single payment to the RippleNet UI.

1. Log on to the Test Harness that sends payments (to run “receiver tests”).
2. Click the **Passive Mode** tab > **Settings** and enable **Auto Settle**.
3. Click the **Single Payment** tab > **Submit Payment** using the default values.
4. Click **OK** to send one payment.
5. Watch the payment lock, settle, and complete on the test record page.
6. Log on to the RippleNet UI and view the payment.


<!-- -->
This scenario requires that the receiving system automatically locks and completes the payment.
