Maximizing Mobile Web Application Testing with Selenium

Maximizing Mobile Web Application Testing with Selenium

5 April 2024 Stephan Petzl Leave a comment Tech-Help

When it comes to ensuring the robustness of web applications across devices, Selenium testing has become a staple in the UI testing domain. However, when extending these testing capabilities to mobile devices, developers often encounter a common question: Is Selenium testing on actual hardware devices worthwhile?

It’s important to understand that the landscape of mobile testing with Selenium has evolved. Initially, Selenium WebDriver included drivers for iPhone and Android that utilized WebView controls, which, while useful, did not always reflect the user experience in the actual browsers like Safari on iOS or Chrome on Android. These drivers, however, have now been deprecated.

Current State of Mobile Testing with Selenium

The past limitations have been addressed by a new generation of tools that build upon the WebDriver project. These tools provide the ability to automate not just web applications but also native and hybrid mobile apps. They support automation on actual devices as well as emulators, offering a more accurate testing environment. The most notable among these tools are:

  • ios-driver: Specifically designed for iOS automation.
  • Selendroid: Focused on Android, especially useful for older versions of Android and applications using WebView.
  • Appium: A cross-platform tool that can automate iOS, Android, and Windows apps.

These projects adhere to the WebDriver’s client API and communicate over the same JSON-over-HTTP-based wire protocol, ensuring consistency and ease of use for those already familiar with Selenium testing.

Choosing the Right Tool for Mobile Testing

Deciding whether to test on actual devices or emulators depends on the specific needs of your application. Here are some considerations to guide your decision:

  • Target Audience: Understand which devices and browsers your audience uses most frequently and prioritize testing on those platforms.
  • Application Complexity: For complex applications, testing on actual devices may provide more accurate results, especially for performance-related aspects.
  • Continuous Integration: Emulators can be more suitable for continuous integration pipelines, offering scalability and automation.
  • Cost and Resources: Actual devices require procurement and maintenance, while emulators can be more cost-effective and easier to manage.

In summary, while traditional Selenium testing may have had limitations on mobile devices, the advent of new tools like ios-driver, Selendroid, and Appium has significantly improved the ability to perform accurate and comprehensive automated testing across various mobile platforms. By understanding your user base and selecting the appropriate tools and methods, you can ensure that your web application provides a seamless experience on all supported devices.

Practical Steps for Mobile Testing

For those looking to integrate Selendroid into their testing suite, here are the basic steps to get started:

  1. Ensure you have Java 6 or higher installed on your system.
  2. Install the latest Android SDK and set the ANDROID_HOME environment variable.
  3. Download the selendroid-standalone jar file.
  4. Launch the Selendroid server with the command:
    java -jar selendroid-standalone-0.17.0-with-dependencies.jar -app selendroid-test-app-0.17.0.apk

Embracing these modern tools will empower developers and testers to achieve more reliable and efficient UI testing for mobile web applications, ensuring quality and performance across the diverse ecosystem of mobile devices.
