Setting up Appium on Android and iOS
Appium functions as a bridge between your test code and the mobile application you like to test. It entitles you to automate interactions on LambdaTest with the application for both Android and iOS devices. Here’s a simplified synopsis of how Appium functions:
- Test Script Creation: You compose test scripts using your selected programming languages. These scripts contain instructions for interacting with the mobile app.
- Appium Server: The Appium server is the root segment that handles the communication between your test script and the mobile device or emulator. It listens for commands from your test script and forwards them to the mobile device.
- Driver Initialization: In your test script, you initialize a driver entity with specific capacities. These capacities contain details about the device and the application to be tested.
- HTTP Server and JSON Wire Protocol: Appium utilizes an HTTP server to obtain and manage HTTP requests from your test script. These requests are transmitted in the form of JSON objects heeding the JSON Wire Protocol, a standardized way of communicating test commands.
- Automation Framework: Relying on the platform (Android or iOS), Appium interacts with the mobile device’s native automation framework. For Android, it might use UIAutomator and for iOS, it could be UIAutomation. These frameworks deliver the means to interact with the application’s user interface segments.
- Command Execution: When your test script transmits a command to the Appium server. Then it decodes this into a series of low-level interactions with the mobile app. The mobile automation framework runs these interactions on the application.
- Response Handling: After conducting a command, the Appium server accepts responses from the device’s automation framework. It rephrases these responses into JSON format and sends them back to your test script as a reaction.
- Test Script Execution: Your test script continues to issue commands, interact with the app, and execute validations based on the responses received. This procedure emulates user interactions and thoroughly tests the application’s functionality.
- Logging and Reporting: Appium can generate logs and reports to track the implementation progress and outcomes for a particular test. These logs and reports are beneficial for debugging and setting the application’s quality.
- Cleanup and Teardown: After the test script finishes its execution, Appium assures that resources are cleaned up, and the test conditions are left in a constant state.
Appium is a popular framework to include in your test automation plan. However, it is critical to execute Appium testing effectively. Setting up, running, and scaling in-house device labs is costly.
This necessitates the utilization of an AI-powered test orchestration and execution platform like LambdaTest. With LambdaTest’s online device farm, you can eliminate your in-house device labs and enable your developers and testers to conduct Appium testing on real device cloud from anywhere and at any time.
Appium automation for Android
Automating Android applications with Appium is an effective method to ensure the functionality and dependability of your mobile applications. Here’s a high-level overview of the stages involved in Appium automation for the Android platform as mentioned below:
1. Install Appium: Install Appium on your development machine. You can do this by using Node Package Manager or by downloading the Appium Desktop application. It depends on your choice.
2. Set Up Android SDK: Confirm that you have the Android SDK installed and appropriately configured. The SDK furnishes the tools and libraries needed to work with Android devices and emulators.
3. Configure Desired Capabilities: Specify the preferred capacities in your Appium script. These capabilities define information about the Android device or emulator you want to use for testing.
4. Start Appium Server: Establish the Appium server on your local machine. This server works as a bridge between your test script and the emulator.
5. Initialize the Android Driver: In your test script, construct an instance of the Android Driver class. This driver denotes the Android device or emulator with the specified expected credentials.
6. Automate Interactions: Use the Android Driver to interact with the application’s user interface segments. You can execute various actions by this process.
7. Assertions and Verifications: Execute assertions and verifications to ensure that the application behaves. You can check for exact text, element presence, or any other standards relevant to your test cases.
8. Handle Waits and Timeouts: Include mechanisms for managing waits and timeouts in your script. This guarantees that your automation code waits for elements to appear or actions to complete before proceeding.
9. Logging and Reporting: Execute logging and reporting mechanisms to capture the execution details and test outcomes. This supports troubleshooting and furnishes visibility into the test results.
10. Test Cleanup: After the complete test script execution, perform any required cleanup tasks, such as closing the application, resetting the device state, or shutting down the Appium server.
11. Run Test Suites: Organize your test scripts into test suites to cover different factors of your Android application. You can utilize test runners or frameworks for test suite management.
12. Analyze Outcomes: Check the test results and logs to specify any problems or failures. Address any flaws found in the application code.
