\# Integration test Testing is an essential step to ensure that the integration is working correctly and that payments are processed without errors. This prevents failures when the checkout is available to buyers. For this, use the test buyer account automatically created with your application. With it, you can simulate payments and validate their functionality. Below, we present the step-by-step process: ## Get a test buyer account To test the integration, make a test purchase using the test buyer account that was automatically created with your application. To find it, follow the steps below. 1\. In \[Mercado Pago Developers\](https://www.mercadopago.com.co/developers/en/docs), navigate to \[Your integrations\](https://www.mercadopago.com.co/developers/panel/app) at the top right of the screen and click on the card corresponding to the application you are developing. 2\. After accessing "Integration data," go to the \*\*Test Accounts\*\* section in the left sidebar. 3\. In the selector menu, click on \*\*Buyer\*\*. Once there, you will see the \*\*operating country\*\* of the account, the \*\*User ID\*\*, the \*\*username\*\* and \*\*password\*\* of the test account. !\[testuser\](https://www.mercadopago.com.co/images/snippets/test-cross/test-accounts-buyer-es-v1.png) > NOTE > > If you need to run tests for another country, create a \[test account\](https://www.mercadopago.com.co/developers/en/docs/checkout-pro/test-accounts) of type \*\*Seller\*\* and another of type \*\*Buyer\*\*, making sure to select the country you want to integrate.
