1. Introduction:

Appium is an open-source automation tool for mobile applications. It is a cross-platform tool that is used to automate native, hybrid, and mobile web applications running on ios, android, and windows platforms. In this tutorial, we are going to set up Appium and run a sample example.

2. prerequisites:

1. Installed JDK
2. NodeJs

3. Download and run Appium:

Download the latest version of the Appium desktop App Image from here. Under "Assets" download AppImage for Linux. Go to download directory and open terminal. Give permission for the app image file.

 

chmod a+x

Now, execute the AppImage file either by double-clicking it or running the following command.

./AppImage

You can see as the Appium Ui started similar to this.

Now, start the Appium server with default port 4723 by clicking the "Start Server" button.

4. Setup Android Emulator:

In order to set up an Android Emulator, you can set it up via a command-line tool without installing an android studio but here, we are going to download an android studio and set up android SDK to run Emulator. For this download android studio from here. Extract the downloaded tar file.

 

tar -xvf android-studio.tar.gz

Go to the extracted directory cd to the bin directory you can see the studio.sh simply execute this sh file by opening the terminal. Which will popup the android studio setting import option. Select "Do not import settings". Click "Next", select "Standard" and verify the setting. Make sure to verify the path of SDK installed.

Click "Next" and "Finish" which will download the SDK on the SDK folder mentioned.

Now, we need to configure the android virtual device for this click "Configure" and select "AVD Manager".

If you see "dev/kvm device: permission denied" you can give permission for the user by using the command:

sudo chown yourLinuxUser /dev/kvm

Create a Virtual Device

After that, select the downloaded image and click "Next" and verify android virtual device configuration and click "Finish" to finish the virtual device setup. Now you can launch the virtual device in the Emulator.

Now, let's configure the SDK path in our system. For this open bashrc file by using the command:

 

  sudo gedit ~/.bashrc

Add the following line at the end of the file.

 

  export ANDROID_HOME=/home/kchapagain/Downloads/Sdk
export PATH=$ANDROID_HOME/emulator:$ANDROID_HOME/tools:$PATH
export PATH=$PATH:$ANDROID_HOME/platform-tools

Make sure you provided the correct download SDK path in "ANDROID_HOME" in my case it's "/home/kchapagain/Downloads/Sdk". Save the file and reload the changes by using the command:

 

  source ~/.bashrc

You can launch the device on Emulator via the command line so that you don't need to open the android studio each time you run the device. For this, open the terminal use command:

emulator -list-avds

Output:

Pixel_2_API_28
Pixel_2_API_28_2

Here, we have two virtual devices installed in your case it will output the list of devices downloaded.

Now, run the device on the Emulator using command:

emulator -avd Pixel_2_API_28

User your device name instead "Pixel_2_API_28". It will run the android virtual device on Emulator.

 

5. Download and load library for Java Client:

Download the Appium java client jar from here.

Similarly, download JUnit jar from here.  Download selenium from here.

Create a java project and create a package called "libs" under "src". Copy all the downloaded jar file in this package and load the jar file from Ide.

For IntelliJ Idea:

Go to: File >> Project Structure(Ctr + Alt + Shift + s) >> Libraries and click the + icon on the top left corner and select package.

6. Setup driver config for Appium:

Create a sample class to config the android driver. Here, we are using the sample calculator app to test and the driver setup config looks like below:

 @Before
    public static void setUp() throws MalformedURLException {
        DesiredCapabilities cap = new DesiredCapabilities();
        cap.setCapability("platformName", "Android");
        cap.setCapability("deviceName", "50b6ab0");
        cap.setCapability("appPackage", "");
        cap.setCapability("appActivity", "");
        cap.setCapability("automationName", "UiAutomator1");
        cap.setCapability("autoGrantPermissions", true);
        cap.setCapability("autoAcceptAlerts", "true");
        driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), cap);
    }
