For that we can use UiAutomator2Options class or using DesiredCapabilities class

Steps:

Step1:

Need to set capabilities using the method setCapability () and need to give the values in the key value pair

Ex:

UiAutomator2Options cap = new UiAutomator2Options();

DesiredCapabilities cap = new DesiredCapabilities();

cap.SetCapability ("deviceName", "realme C33"); // Mobile name cap.setCapability("platformVersion", "13"); // Android version of your phone

cap.setCapability("app", "path of the Apk in your project");

Step2:

After setting the capabilities we need to give these details to the object of AndroidDriver

Android driver = new AndroidDriver(new URL("http://127.0.0.1:4723"),cap);

*****for the above code we need to manually start the appium server using the appium command from the cmd using the command “appium”*****

How to start appium server automatically before the test starts ?

To start the appium sever from the code (automatically) we have to use object of AppiumServiceBuilder class

Steps:

Step1:

create an object of AppiumServiceBuilder class and use the method withAppiumJS() and pass the path of the main.js file as the argument in the new file object

service = new AppiumServiceBuilder().withAppiumJS(new File("C://Users//Admin//AppData//Roaming//npm//node_modules//appium//build//lib//main.js"))

Step2:

give the ip address and port and build() the method.

service = new AppiumServiceBuilder().withAppiumJS(new File("C://Users//Admin//AppData//Roaming//npm//node_modules//appium//build//lib//main.js")).withIPAddress("127.0.0.1").usingPort(4723).build();

Step3:

use service.start() method to start the server and sevice.close() to close the server

*****use start() in beforemehtod annotation and sevice.close() in aftermethod annotation after driver.quit*****
