# Conduct sandbox acceptance testing

> Before launching the application on the Alipay+ Developer Center, you need to conduct sandbox acceptance testing.

## Step 1: Check the sandbox configurations

Before conducting sandbox acceptance testing, ensure that you have completed the following items:

-   Receive sandbox resources.
-   Configure the sandbox.
-   Perform free tests in the sandbox with development tools.

This step helps you to ensure that the sandbox is configured correctly and stable enough for acceptance testing. For step-by-step instructions, see [Develop in the sandbox](develop_in_sandbox.md).

## Step 2: Perform testing with test cases

On the **Sandbox** > **Acceptance Test** page, follow these steps:

1.  Find the test case groups provided by Alipay+. These test groups are allocated to you automatically after you select the integration products while creating an application.

2.  Conditional: If there is a hint presenting "**Upgrade needed**", click **Upgrade** to view the upgrade details and upgrade the test case groups to the latest version.
