Test Subsystem ChangeLog

cl.testfwk_arkxtest.1 Exception Handling Support of On, Driver, and Component APIs

The original APIs in API version 8 are deprecated, and substitute APIs that support exception handling are introduced in API version 9. You must use try catch to capture exceptions thrown by the APIs.

Change Impacts

This change affects the JS APIs in API version 9 provided by @ohos.uitest. If you have used the API of @ohos.uitest-api9 during test case development, adaptation is required so that the compilation can be successful in the SDK environment of the new version.

Key API/Component Changes

The By class in API version 8 is deprecated and replaced by the On class in API version 9. The APIs of the On class support exception handling and retain their original name, with the exception of By#key, which is renamed On.id.
The BY object in API version 8 is deprecated and replaced by the ON object in API version 9.
The UiDriver class in API version 8 is deprecated and replaced by the Driver class in API version 9. The APIs of the Driver class support exception handling and retain their original name.
The UiComponent class in API version 8 is deprecated and replaced by the Component class in API version 9. The APIs of the Component class support exception handling and retain their original name.

Adaptation Guide

Adapt to the API name changes.

You can replace the class name according to the following rules:

By-->On
BY-->ON
UiDriver-->Driver
UiComponent-->Component
Catch and handle exceptions.

Use try-catch to catch and handle exceptions thrown by the APIs. Below is the sample code:

   import {Driver,ON,Component} from '@ohos.uitest'
   
   try {
       let driver = Driver.create();
   } catch (error) {
       // error handle; error.code indicates the error code.
   }
