Tips

• If you are using a virtual environment, please make sure to activate it before running the command.

• On iOS, please ensure that WDA is successfully started and wda port forwarding is successful in advance.

  • First, Use xcode or tidevice or go-ios to launch wda.

  tidevice xctest -B <wda_bundle_id>
  

  • Second, Use tidevice or iproxy to forward the wda port，and keep it running.

  tidevice relay 8100 8100
  

  • And then, To ensure the success of the browser to access http://localhost:8100/status, return like this:

  {
    "value": {
        "build": {
            "productBundleIdentifier": "com.facebook.WebDriverAgentRunner",
            "time": "Mar 25 2024 15:17:30"
        },
        ...
        "state": "success",
        "ready": true
    },
    "sessionId": null
  } 
  

  • Finally, Input the wdaUrl in the web page, such as http://localhost:8100

• On iOS，WDA can easily freeze when dumping high UI hierarchy. You can reduce the maxDepth on the web page. The default is 30.
