The UiTest framework provides a wide range of UI component feature description APIs in the **By** class to filter and match components. The UiTest framework provides a wide range of UI component feature description APIs in the **By** class to filter and match components.<br>
The API capabilities provided by the **By** class exhibit the following features: The API capabilities provided by the **By** class exhibit the following features: <br>1. Allow one or more attributes as the match conditions. For example, you can specify both the **text** and **id** attributes to find the target component. <br>2. Provide multiple match patterns for component attributes. <br>3. Support absolute positioning and relative positioning for components. APIs such as [By.isBefore](#byisbefore) and [By.isAfter](#byisafter) can be used to specify the features of adjacent components to assist positioning. <br>All APIs provided in the **By** class are synchronous. You are advised to use the static constructor **BY** to create a **By** object in chain mode.
- Allows one or more attributes as the match conditions. For example, you can specify both the **text** and **id** attributes to find the target component. ```js
