UI Browser Automation using Appium with Visual Studio Android Emulator

Appium is an open source cross platform automation tool for native/hybrid and mobile web based apps.

Why?

You can use Appium with various language like c#, java, Objective C with Selenium driver. Thus a truly cross platform automation tool!

How?

Machine which is running the web driver scripts communicates with Appium server through Http/JSON and in turn the Appium sends/receives the command to Devices/Emulators of Android or IOS platforms.

Most common Issues !

1. Unable to connect to remote server - no connection could be made because the target server actively refused it 127.0.0.1:4723

Resolution : Ensure the Appium server is running. And the IP address is entered correct in the Appium server settings page. Verify the desired capabilities parameters.

2.  A new connection could not be created. An unknown server side error occurred while processing the command. Unknown error. Device <IP address> is not online.

Resolution:

- Verify if the emulator/device is connected through adb devices -l in command prompt.

- Desired capabilities should be properly entered. Ex: devicename/platformversion/udid/platformname.

- Check for Appium settings. Restart the Appium server.

 

3. Could not find a connected Android device.

Resolution:

Ensure the android device or emulator is running. (goto command prompt, goto Android SDK\Tools\ and run adb devices -l)

      Hi Phanindra, you can run this command "adb devices -l" under your Android SDK\Tools folder. Emulator will also have a UDID. can you tell me the result when you run the above command? . is it empty?
