Getting Started with Selenium Mobile Testing
Here’s how you can get started with it:
Step 1: Setting Up Your Environment
Before you start mobile testing, it’s important to get your environment in place. Here’s how you can do that.
- Install Java Development Kit (JDK)
Make sure you have the latest version of JDK installed on your device. This is required for running Selenium tests since it is built on Java.
- Download Selenium WebDriver
Get the right WebDriver for your browser from the official Selenium website. Ensure that the version matches your browser’s version to avoid compatibility issues.
- Select a Test Framework
For Java developers, TestNG or JUnit are some of the preferred options. These frameworks ease the organization of tests as well as control the run of tests and generate test reports.
- Setup Appium
Appium is open-source and lets you work with automation techniques for mobile apps on both Android and iOS devices. Download it from the official site, and besides that, you will have to install Node.js.
- Install Extra Dependencies
Depending on your project needs, you may require more libraries or dependencies that involve your testing framework or Appium.
Step 2: Configuring Desired Capabilities
Desired capabilities are key-value pairs defining the properties of the mobile application you wish to test. Correct configuration is required for a successful test execution:
- platformName
Specify either ‘Android’ or ‘iOS’ depending on the platform you want to test against.
- deviceName
Fill with the name of the device to be tested on (‘Pixel_3’, ‘iPhone_11’).
- app
Enter the path for the application file (it has to be an APK file on Android and an IPA for iOS).
- automationName
Enter ‘Appium’ to use the automation driver to test on mobile.
Step 3: Writing Your First Test
The following should be taken into account for writing your first test:
- Initialization of Appium Driver
First, establish a connection from your test script to the Appium server running on your device.
- Locate Elements and Perform Actions
Locate elements within your application interface using different locator strategies such as ID, XPath, or class name. Then, perform actions such as clicking buttons or entering text.
- Verify Outcomes
After performing the actions, verify that the outcomes meet expectations by checking User Interface (UI) elements or text values displayed in your app.
- Close the Driver
Always ensure that you close the driver after the completion of tests. This is to free the system resources.
Step 4: Running Tests
Testing on actual devices yields more precise results compared to emulators or simulators. First, connect your physical device using a USB cable and ensure that the USB debugging option is activated in the device’s settings. After that, you can use Appium for test execution by launching the application and initiating tests while specifying the correct device configurations.
Though emulators are convenient and are quite resourceful for the initial phase of testing, they generally do not mirror the situations in real life. Exposing issues like differences due to hardware, network, battery performance, and UI might be missed by the emulation process. For example, native features such as a device’s GPS sensor or usage of the battery may give an idea of how the application will work in daily circumstances.
Step 5: Leveraging Cloud Testing for Selenium Mobile Testing
As organizations scale their testing efforts, cloud-based platforms like LambdaTest become invaluable tools in their arsenal. LambdaTest provides access to over 3000 real desktop and mobile environments for browser and app compatibility testing, making it a powerful ally for mobile website testing.
With features such as blazing-fast execution that allows users to run tests quickly across multiple environments simultaneously, it ensures faster release cycles while optimizing resource usage. Additionally, its auto-healing tests automatically recover from flaky tests without manual intervention, enhancing overall test reliability.
Security is of utmost importance for LambdaTest, which is SOC2 Type 2 certified and GDPR compliant, ensuring that sensitive data remains protected during testing processes. Cross-browser compatibility testing is also supported on the platform, and users can validate applications across different devices and browsers to maintain the highest quality standards.
LambdaTest platform also integrates well with popular Continuous Integration/Continuous Deployment (CI/CD) tools such as Jenkins and Travis CI, thereby allowing continuous automation of testing and instant feedback on code changes. With the help of LambdaTest, you can run Selenium tests with ease across different devices without any infrastructure setup or maintenance costs associated with physical devices.
Common Challenges in Selenium Mobile Testing
