Experience rating is used to rate the user experience of a Mini Program. It performs real-time checks when Mini Programs are running, analyzes problems that may lead to bad experiences, locates problems, and provides optimization suggestions.

# Runtime Environment Requirements

• Download and install Weixin DevTools 1.02.1808300 or above. Click here to download.
• The base library needs to be switched to version 2.2.0 or above.

# How to Use

1. Open Weixin DevTools and switch the base library to version 2.2.0 or above in Details.
2. Switch to the Audits panel in the debugger area
3. Click the Start button in the upper left corner (see the figure below) and perform operations on the Mini Program interface. When run, the page will be detected by "Experience Rating".
4. Click Stop to stop analysis. You will then see an analysis report that you can use to make optimizations.

# Automatic Operation

To make it easy for developers to find any Mini Program experience issues in a prompt manner, we added "Automatic Operation" in Experience Rating starting from version 1.02.1811150.

This feature checks the experience score in real-time during the development and debugging of a Mini Program. If the score is lower than the threshold, a warning message will appear in Console, and developers can see the details in Audits.

To enable this feature, in the upper right corner of Weixin DevTools, check Run Experience Rating Automatically in Details.
