Multiple Android target API support (10 to 19).
Built in Inspector to simplify test case development.
Selendroid can be extended at runtime with your own extensions.
Selendroid can interact with multiple Android devices (emulators or hardware devices) at the same time.

Drawbacks of Selendroid

The drawback of this tool is that it is quite slow and on some machines with less than 4GB RAM, it is unusable.

How to Use Selendroid

Step 1 − The prerequisites to use Robotium is Java SDK (minimum 1.6). If you don’t have Java installed on your system, then follow the steps given below.

Download JDK and JRE from Oracle JavaSE
Accept license agreement.
Install JDK and JRE.
Set environment variable as shown in the screenshot below.

Step 2 − Download Android Studio from SDK Android (It will take time because of the size of the file).

Double click the exe and run the installer.
Continue with all default options.
Set the ANDROID_HOME.

Step 3 − Download Selenium jar files and test application from Selendroid

Download selenium jar file and test app.
Place it into any folder i.e. D:\SelendroidJars.

Step 4 − Physical device with USB cable.

Make sure that the device is attached to the workstation with USB cable.
Make sure the USB debugging mode (under setttings → Developer options) is enabled.

Test an App with Selendroid

To test an App using Selendroid, follow the steps given below −

Step 1 − Install Eclipse.

Step 2 − Create a Java project.

Step 3 − Add the downloaded Selendroid jar file to the newly created project.

Step 4 − Add the downloaded Selenium jar files to the newly created project.

Step 5 − Configure testNG in the Eclipse.

Step 6 − Connect the mobile devices with the system using USB cable. Set the USB debugging mode from the developer’s options under settings.

Step 7 − Run the Selendroid server. Open command prompt and write the following code and hit Enter −

java -jar selendroid-standalone-0.17.0-with-dependencies.jar -app selendroid-test-app-0.17.0.apk

Selendroid-standalone will start an http server on port 4444 and will scan all Android virtual devices (avd) that the user has created (~/.android/avd/).

Open the web browser and navigate to: http://localhost:4444/wd/hub/status.

Step 8 − Create a Java Project; add Selendroid Standalone libraries, Selenium jars, and JUnit libraries in the build path.

Step 9 − Create package under the Java project.

Step 10 − Create a class under the package and write the following code.

package selTest;

import io.selendroid.SelendroidDriver; 
import io.selendroid.common.SelendroidCapabilities;
import io.selendroid.standalone.SelendroidConfiguration;
import io.selendroid.standalone.SelendroidLauncher;

import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.WebElement; 

import org.testng.Assert; 
import org.testng.annotations.AfterSuite; 
import org.testng.annotations.BeforeSuite; 
import org.testng.annotations.Test;

public class SelendroidTest {

   private WebDriver driver ;

   @BeforeSuite 
   public void setUp() throws Exception {
      SelendroidConfiguration config = new SelendroidConfiguration();
      config.addSupportedApp("selendroid-test-app-0.9.0.apk");
      SelendroidLauncher selendroidServer = new SelendroidLauncher(config);
      selendroidServer.launchSelendroid();
	  
      SelendroidCapabilities caps = new
         SelendroidCapabilities("io.selendroid.testapp:0.9.0"); 
      driver = new SelendroidDriver(caps);
   }
   
   @Test 
   public void selendroidTest() throws Exception {
      WebElement inputField = driver.findElement(By.id("my_text_field"));
      Assert.assertEquals("true", inputField.getAttribute("enabled"));
      inputField.sendKeys("Selendroid");
      
      Assert.assertEquals("Selendroid", inputField.getText());
	  
      WebElement button = driver.findElement(By.id("buttonTest"));
      button.click();
	  
      button = driver.findElement(By.id("button2"));
      button.click();
      
      Thread.sleep(5000);
	  
      button = driver.findElement(By.id("startUserRegistration"));
      button.click();
      
      Thread.sleep(10000);
	  
      WebElement element = driver.findElement(By.id("label_username")); 
      
      String text = element.getText();
      System.out.println(text);
      element = driver.findElement(By.id("inputUsername"));
      element.sendKeys("bob");
      
      element = driver.findElement(By.id("inputEmail"));
      element.sendKeys("test@gmail.com"); 
      
      element = driver.findElement(By.id("inputPassword"));
      element.clear();
      element.sendKeys("test1233");
      
      element = driver.findElement(By.id("inputName"));
      element.clear(); 
      element.sendKeys("My Name ");
	  
      element = driver.findElement(By.id("input_preferedProgrammingLanguage")); 
      element.click();
      
      element = driver.findElement(By.id("text1"));
      element.click();
	  
      element = driver.findElement(By.id("input_adds"));
      element.click();
	  
      element = driver.findElement(By.id("btnRegisterUser"));
      element.click();
      
      element = driver.findElement(By.id("buttonRegisterUser"));
      element.click(); 
   }
   
   @AfterSuite 
   public void tearDown(){ 
      driver.quit(); 
   } 
}

Step 11 − Run the class with testNG run configuration.
