Prerequisites for Using Appium
Before dealing with Appium, you will need to have some components available on your system. The first one is the Java Development Kit (JDK). Download the latest version directly from the website of Oracle and install it. Once installed, set up the JAVA_HOME environment variable so that your Java is resolved and recognized by your system.
The next one is Node.js, upon which Appium works. Download and install the same from its official website by verifying the installation with node -v inside your command prompt or terminal.
Next, you would install the Appium server. This can be done using npm, which comes with Node.js. Open the terminal or command prompt and then run npm install -g appium to install Appium. After you have installed it, you can try to check its accessibility by using the command appium -v.
Finally, depending on the programming language of your choice, you would then install the necessary Appium Client Libraries. For instance, if you are using Python, you will run the pip install Appium-Python-Client command to ensure that you have the libraries necessary to write tests.
Installation of Appium
Download the JDK from the official Oracle website and install it. After installation, follow the installation instructions and then define in your system settings the environment variable JAVA_HOME pointing to the path of JDK installation.
Downloading and running Node.js can be done from its official site; just head over to the site and download an installer appropriate for your type of Operating System (OS). After executing the downloaded file, check if everything went correctly with the command: node -v in your terminal.
Open your command prompt or terminal and write therein, ‘npm install -g appium.’ This command will install Appium on your system. After installation, verify it by typing appium -v.
Finally, to install client libraries like Appium-Python-Client, use pip by running pip install Appium-Python-Client. All these steps will ensure that you have all the prerequisites set up for effective use of Appium in mobile application testing.
Starting the Appium Server
When all installations are sorted, you can go ahead and start the Appium server as mentioned. If you are on Windows, you should open your command prompt; if you are on Mac or Linux, then you should open your terminal
Next, type the command appium and hit Enter. This command initializes the Appium server. After the execution of the command, look at the logs in your command line interface.
You should see output showing that the server is running successfully, beginning with a line like “[Appium] Welcome to Appium v2.0.0.”. If you see this welcome message, your Appium server is up and running. You can stop the server by pressing CTRL+C when you are done.
Writing Your First Test Script
With all the above settings, you can finally create your first test script. In the tutorial, we are going to test a simple Android application. Firstly, you have to create an instance of the Desired Capabilities object. It’s simply a dictionary containing key-value pairs describing your test environment.
You should state whether you are going to test on Android or iOS and give the details regarding the app under test: name of the platform (for instance, “Android” or “iOS”), version of the platform (for instance, “11” for Android 11), name of the device (for instance, “Android Emulator”), and path to your application file, APK for Android
Once you’ve defined your desired capabilities, you initialize the WebDriver using these settings. After the driver is set up, you can begin interacting with User Interface (UI) elements in your app.
You use a variety of strategies to locate elements, from their unique IDs and class names to XPath expressions for more complex queries. After locating the elements, you might click buttons, enter text into input fields, or verify the visibility of the elements.
Execute Your Test Script
To run your test script successfully, you should run it in your preferred development environment or command line interface. Make sure the Appium server is running before running the script. As you run your test, keep a close eye on the execution; you should see your app being tested automatically as defined in your script.
Now you will see that the actions you are performing on the app, its button clicks, and text entries, allow you to be sure that everything works as you expect. That’s it for this tutorial: following these instructions will help you efficiently start up the Appium server and write and execute your first automated test script for mobile applications.
