Can Selenium Be Used for Mobile Testing?
Selenium is primarily designed to automate web browsers on desktops. It does not test mobile applications directly. Selenium can be used to test a website on a mobile browser, whereas Appium or Selendroid would be needed for native or hybrid mobile application testing.
Mobile web testing entails checking the behavior of a site on a phone or tablet’s browser. This is achievable through Selenium WebDriver because it is able to execute tests against mobile browsers. Native and hybrid apps require native tools for testing gestures, hardware buttons, and app-specific events.
Appium and Selendroid are frameworks developed over Selenium. They allow you to use Selenium-like scripts for testing mobile apps. Both Android and iOS are supported by Appium, whereas Selendroid primarily supports Android. These tools make Selenium’s capabilities available on mobile devices.
Overview of Selenium-Based Mobile Testing Frameworks
Appium and Selendroid are popular frameworks that extend Selenium for mobile testing. They let you use Selenium scripts to automate tests on mobile devices.
Appium is extensively used to test Android and iOS applications. It can be very well used to automate native, hybrid, and mobile web applications. Appium seamlessly uses the WebDriver protocol. And then you can easily code tests in various languages like Java, Python, or JavaScript. You do not have to modify your Selenium knowledge to apply Appium. Appium supports real devices, emulators, and simulators.
Selendroid is yet another Android app automation tool. It is also Selenium-based. Selendroid supports hybrid and native Android apps. You can easily integrate real Android devices or emulators for your testing with Selendroid. It also supports hot plugging of devices, i.e., you can quickly plug in or unplug devices during test runs.
Both Selendroid and Appium have parallel testing capabilities. You can execute tests on multiple devices simultaneously. This is time-saving and provides greater coverage. They also allow you to inspect User Interface (UI) elements and debug your test.
These frameworks are simple to use for testing mobile apps with Selenium-like scripts. You can apply your web testing experience to mobile projects. Appium supports more and has broader support, and Selendroid is optimized for Android-based projects.
These tools help teams automate native, web, and hybrid mobile testing of applications. This helps them deliver better quality apps more quickly and with fewer defects.
How Selenium Works for Mobile Web Testing?
Selenium WebDriver is able to test web applications on mobile browsers. You write scripts to open a site, click buttons, and verify results, just as you would with a desktop browser. This comes in handy when testing websites on tablet browsers and mobile phones.
For mobile testing, you can use emulators or real devices with browser drivers. Emulators mimic a real tablet or phone on your computer. Real devices provide more realistic results because they show what the user sees.
Cross-browser and cross-device testing is also necessary. Your site must function on Chrome, Safari, and other browsers on iOS and Android. Selenium makes this feasible by allowing you to test across various browsers and devices.
Selenium is apt for mobile web testing but not for native app testing. For mobile apps, use tools like Appium. If you just want to test your site on mobile browsers, Selenium WebDriver is a fast and effective option.
Setting Up a Mobile Testing Project with Selenium and Appium: A Step-by-Step Guide

Install Selenium client libraries for your target programming language (Java, Python, C#, etc.). These libraries allow your code to interact with Appium.
Step 3: Set Up Device or Emulator
Ready your mobile device or emulator. For Android, make use of a real device or an Android Emulator. For iOS, make use of a real iPhone or iOS Simulator.
Step 4: Connect the Device to the Computer
Connect your device or begin with the emulator, and make sure it is detected by your computer. This connection is required to perform tests.
Step 5: Configure Desired Capabilities
Set desired capabilities such as device name, platform version, app package, or browser name in your test script. They indicate to Appium the test environment.
Step 6: Init Appium Server
Open the Appium server and let it listen to wait for test scripts to send commands to the Appium server.
Step 7: Create a Test Script
Craft a basic test script with Selenium WebDriver commands for launching a browser or an application and doing tasks like clicking or entering.
Step 8: Run Your Tests
Run your test script and see it run on the connected device or emulator. Check the results to confirm that the test worked as expected.
