This testing option is available by default when you add Alipay in your test Customer Area. The payment method type is `alipay`. To test a redirect payment: 1. Start a payment as usual in your integration. The shopper is redirected to an Adyen-hosted simulator page. 2. Select the payment outcome that you want to test. 3. Wait for the simulator to return the shopper to your website, then complete the payment as usual. For an Advanced flow, make a `/payments/details` request. 4. Confirm that your integration handles the outcome that you selected, and that the payment appears in your [Customer Area](https://ca-test.adyen.com/) > **Payments** > **Payment list**. ### Test directly with an Alipay wallet You can also test directly with an Alipay wallet: 1. Get an Alipay wallet app and set it up with a credit or debit card. 2. Make a live penny test, which is a payment for a minimal amount.
