Encountering an “Unknown server-side error” while processing commands in Appium can be a common issue for developers working with automated testing frameworks. This error typically arises when there is a communication problem between the Appium server and the remote device. In this guide, we’ll explore some effective solutions to help you resolve this issue and ensure smooth execution of your automated tests.
Understanding the Issue
The error message usually looks like this:
org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original error: Could not proxy command to remote server. Original error: Error: socket hang up
This error can occur due to various reasons, including issues with the Appium server, device connectivity, or configuration problems in your test scripts.
Recommended Solutions
Here are some solutions that have proven effective in resolving this error:
Solution 1: Uninstall and Reinstall Appium’s UIAutomator2 Servers
One of the most effective solutions is to uninstall the Appium UIAutomator2 servers and then restart the Appium server. Follow these steps:
adb uninstall io.appium.uiautomator2.server
adb uninstall io.appium.uiautomator2.server.test
After executing these commands, restart your Appium server and run your tests again.
Solution 2: Simple Restart
Sometimes, a simple restart of both the Android emulator and the Appium server can resolve the issue. This approach is straightforward and can be effective:
- Stop your Android emulator.
- Restart the Appium server.
- Restart the Android emulator and rerun your test scripts.
Solution 3: Check Driver Instances
If you have multiple driver instances running in your code, it might cause this error. Ensure that your test suite initializes the driver only once:
URL url = new URL(Common.getProperty("URL"));
driver = new AndroidDriver<WebElement>(url, capabilities);
Advanced Solution
If you are using a real device and face the issue, try disconnecting and reconnecting the USB cable. For emulators, shut them down and restart them.
Leveraging Repeato for Efficient Test Automation
While Appium is a powerful tool for mobile test automation, it can sometimes be slow and tests may become unstable. This is where Repeato can offer a significant advantage. As a no-code test automation tool, Repeato allows you to create, run, and maintain automated tests for your iOS and Android apps with ease. It uses computer vision and AI to ensure your tests are not only faster to create but also run at blazing speeds, providing a more stable and efficient testing environment.
