# Conduct sandbox acceptance testing

> Before inviting ACQPs for authorization and launching the application, you need to conduct sandbox acceptance testing in the Alipay+ Developer Center.

## 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).

## 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.

5.  To execute the test case, click **Start**. Follow the instructions to test and pass all required test cases in the sandbox. Note that it is required to upload a screenshot, a photo, or a video in some cases.
