Android testing using Selenium:

As we all know selenium supports android testing and below I will demonstrate opening a Google page in android emulator.

For android testing in selenium first we have to down load the Android SDK, and unzip it.

Go to Eclipse IDE and perform the below mentioned steps

1. Help-> Install New Software..

·         Click on “Add…” button

·         Name : Enter name <<Android_Plugin>>

·         Location: Enter the URL https://dl-ssl.google.com/android/eclipse/

·         Click on “Ok” button

·         Click on “Select All” button or check all the check boxes

·         Click on “Next” button

After importing the android plug-in the below screen will be displayed, click on “Next” button

Select the “I accept the terms of license agreement” radio button and click on “Finish” button

Wait until the software is installed, If it throws any warning click “OK” button. After the installation it will ask for the restart eclipse, Click on “Yes” button.

After the eclipse restart perform the below steps

2. Windows-> Preferences

·         Select “Android“ in left side tree options

·         Click on “Browse” button in front of SDK Location text box

·         Select downloaded file “android-sdk-windows”

·         Click on “OK” button

·         Click on “Apply” and “OK” button as below

Ex: << C:\android-sdk-windows>>

Note: The downloaded “android-sdk-windows”file should contain the “android-17” in platforms folder.

If the file does not contain the“android-17” in platforms folder the perform the below steps.

• Windows-> Android SDK Manager

o    Select all the Available Packages in Android SDK Manager

o    Like Tools, Android 4.3 (API 18), Android 4.2.2 (API 17) etc..

o    Click on “Install Packages…”

Installation will take some time, after installation close the Android SDK Manager window

• Navigate to “android-sdk-windows” file Ex: C:\android-sdk-windows\platforms and check for “android-17” folder exists.

3. Download “android-server-2.21.0.apk ” from the following locationhttp://code.google.com/p/selenium/downloads/list and Copy the downloaded file into folder “C:\ android-sdk-windows\platform-tools”.

4. Navigate to Eclipse IDE Windows >> Android Virtual Device Manage

· Click on “New…” button

· Enter AVD Name: <<Sample1>>

· Select Device: <<Nexus One (3.7”, 480 * 800: hdpi)>>

· Select Target: <<Android 4.2.2 – API Level 17>>

· Click on “OK” button

• Select the added Android Virtual device and click on “Start” button and click on “Launch” button, the emulator will start opening as below

• For the first time it will take quite long time to open emulator. Once the emulator is opened close the Android Virtual Device Manager window. The emulator looks like below

5. Run the “Command Prompt” as administrator and execute the below commands

· Execute“cd C:\ android-sdk-windows \platform-tools”

· Execute the command “adb install android-server-2.21.0. apk”

 

• We also need to set up Port forwarding, run the command “adb forward tcp:8080 tcp:8080"

6. After the APK install successfully the WebDriver icon will appear in emulator. Click on the WebDriver app on Emulator and this will make the android server available at “http://localhost:8080/wd/hub”.Opening this URL in Firefox will show up a blank page on success.

 

Now create new project for android and copy the below script which just opens the google page in emulator.

package com.Google.Adroid;

import java.util.Properties;

import java.util.concurrent.TimeUnit;

import junit.framework.TestCase;

import org.openqa.selenium.By;

import org.openqa.selenium.android.AndroidDriver;

public class AndroidSampleProj extends TestCase {

      static Properties prop = System.getProperties();

      public void testProj() throws Exception {

            // Retrieve the project absolute class path

            prop.setProperty("", getClassPath());

            System.out.println(getClassPath());

            // Android Instance creation

            AndroidDriver driv = new AndroidDriver();

            // Implicit wait

            driv.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

            // AUT AppURL

            driv.get("http://www.Google.com");

            // Assertion for Link presence.

            assert driv.findElement(By.linkText("work")).isDisplayed();

            // Click on the work link

            driv.findElement(By.linkText("work")).click();

            // Log the Page title

            System.out.println("Page Title : " + driv.getTitle());

            // Quitting the Android Web Driver

            driv.quit();

      }

static String getClassPath() {

            // TODO Auto-generated method stub

            return prop.getProperty("java.class.path", null);

      }

}

Right click and select option Run As >> 2 JUnit Test and the script runs perfectly

Data Driven Framework

Data Driven Framework:

As the data driven says getting a input data from the outside here I am getting Username and Password values from excel sheet and using those values in my main script. The below is the script for fetching the values from excel sheet.

package com.Google.util;

import java.io.File;

import jxl.Cell;

import jxl.Sheet;

import jxl.Workbook;

public class ExcelReader {

      // * This Method is used to read the data from XSL File.

public static String[][] getTableArray(String xlFilePath, String    

      sheetName, String tableName) throws Exception {

           

String[][] tabArray = null;

            Workbook workbook = Workbook.getWorkbook(new File(xlFilePath));

            Sheet sheet = workbook.getSheet(sheetName);

            int startRow, startCol, endRow, endCol, ci, cj;

            Cell tableStart = sheet.findCell(tableName);

            startRow = tableStart.getRow();

            startCol = tableStart.getColumn();

Cell tableEnd = sheet.findCell(tableName, startCol + 1, startRow + 1,100, 64000, false);

            endRow = tableEnd.getRow();

            endCol = tableEnd.getColumn();

            System.out.println("startRow=" + startRow + ", endRow=" + endRow

            + ", "+ "startCol=" + startCol + ", endCol=" + endCol);

tabArray = new String[endRow - startRow - 1][endCol - startCol - 1];

            ci = 0;

            for (int i = startRow + 1; i < endRow; i++, ci++) {

                  cj = 0;

                  for (int j = startCol + 1; j < endCol; j++, cj++) {

                        tabArray[ci][cj] = sheet.getCell(j, i).getContents();

                  }

            }

            return (tabArray);

      }

}

And the data in the excel looks like this

LoginGoogle	UserName	Password
	abc@gmail.com	xxxxx
			LoginGoogle

The description of the parameters used in the “ExcelReader” function is as below

xlFilePath: The excel file name along with the location of the file.

sheetName: Name of the excel sheet

tableName:  Name of the table, it is the first and last cell names and both should be same.

Ex: Here in above data table name is LoginGoogle

The above “ExcelReader” function with startRow, startCol, endRow and endCol is little bit confusing hence we can use normal one as shown below for the normal excel table without table name

package com.Google.util;

import java.io.File;

import jxl.Cell;

import jxl.Sheet;

import jxl.Workbook;

public class ExcelReader

{

      // * This Method is used to read the data from XSL File.

           

public static String[][] getTableArray(String xlFilePath, String sheetName) throws Exception

      {

            String[][] tabArray = null;

            Workbook workbook = Workbook.getWorkbook(new File(xlFilePath));

            Sheet sheet = workbook.getSheet(sheetName);

            int numRows, numCols, ci, cj;

            numRows = sheet.getRows();

            numCols = sheet.getColumns();

            ci = 0;

            for (int i = 0; i < numRows; i++, ci++)

            {

                  cj = 0;

                  for (int j = 0 + 1; j < numCols; j++, cj++)

                  {

                        tabArray[ci][cj] = sheet.getCell(j, i).getContents();

                        System.out.print(tabArray[ci][cj]);

                  }

            }

            return (tabArray);

      }

}

And the data in the excel looks like this

UserName	Password
abc@gmail.com	xxxxx

Create folder as “resource” and copy the excel sheet and paste under the created folder. After this download the “jxl.jar” file and copy and paste under the “lib” folder and Set path for the copied jar file. Right click on Project select Build Path >> Configure Build Path Select the Add External Jars.. button and navigate to the location where the jar file is kept and select the file and click on Open button.

These methods getWorkbook(), getSheet(), getRows(), getColumns() are part of “jxl.jar” hence we need to use it.

Note: Here the 1^st and last cell concept is not there it’s a normal excel table with column heading without table name.

As we all know selenium best suites in agile process and as it is agile there are chances of changing objects name as project progress. It’s tough to handle the changing objects because we cannot change each and every time in all the places where and all we have used these objects.

To resolve this we can even use external flat files to save our objects or else the .properties file option in java to save our objects. Using .properties files it’s very easy to handle the changing objects by updating the changes only once in .properties file.

To create property file right click on “resource” folder and select file and give the file name as “locators.properties” and add the objects in to it.

Like

#----------------------------------------------------------------------------

#                    OBJECT REPOSITORY

#----------------------------------------------------------------------------

#Keyword = value

UN_ID=Email

PW_ID=Passwd

SIGNIN_ID=signIn

The below is the property file look like

 

Now see the sign in functionality separated as below

Package name: com.Google.Common

Class name: Signin.Java  This class will enter the values in User name and Password textboxes

package com.Google.Common;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import com.Google.util.PropertyFileReader;

public class Signin

{

      PropertyFileReader propObj=new PropertyFileReader();

public void LoginToApp(WebDriver driver, String UserName, String Password)

      {

          driver.findElement(By.id(propObj.getValue("UN_ID"))).

            clear();

    driver.findElement(By.id(propObj.getValue("UN_ID"))).

    sendKeys(UserName);

          driver.findElement(By.id(propObj.getValue("PW_ID"))).

            clear();

    driver.findElement(By.id(propObj.getValue("PW_ID"))).

    sendKeys(Password);

                 

      }

}

The main method is as below which calls all base, signin and signout functions

package com.Google.Main;

import java.io.File;

import java.util.regex.Pattern;

import java.util.concurrent.TimeUnit;

import static org.hamcrest.CoreMatchers.*;

import org.openqa.selenium.*;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.openqa.selenium.support.ui.Select;

import org.testng.Assert;

import org.testng.annotations.AfterSuite;

import org.testng.annotations.BeforeSuite;

import org.testng.annotations.DataProvider;

import org.testng.annotations.Test;

import com.Google.util.PropertyFileReader;

import com.Google.util.ExcelReader;

import com.Google.Common.BaseTest;

import com.Google.Common.SignOut;

import com.Google.Common.Signin;

public class GoogleLogin extends BaseTest {

      private boolean acceptNextAlert = true;

      private StringBuffer verificationErrors = new StringBuffer();

      PropertyFileReader propObj = new PropertyFileReader();

      @DataProvider(name = "DP1")

      public Object[][] createData() throws Exception {

            /*File dir = new File("");

            String folderPath = dir.getAbsolutePath();*/

            Object[][] retObjArr = ExcelReader.getTableArray

            ("C:/SeleniumWorkspace/GoogleMailProject/resource/

            TestData.xls", "Data", "LoginGoogle");

            return (retObjArr);

      }

      @Test(dataProvider = "DP1")

      public void testGoogleLogin(String UserName, String Password)

                  throws Exception {

            String baseUrl = "https://www.google.co.in/";

            driver.get(baseUrl);

            Assert.assertEquals("Google", driver.getTitle());

            driver.findElement(By.id("gb_70")).click();

            Assert.assertEquals("Google Accounts", driver.getTitle());

           

            // Call common function Signin for entering User

            name and Password

            Signin login = new Signin();

            login.LoginToApp(driver, UserName, Password);

            // Click on Sign in button and validate title

            driver.findElement(By.id(propObj.getValue("SIGNIN_ID"))).click();

           

            // Call common function SignOut for loging out

            SignOut logout = new SignOut();

            logout.LoginToApp(driver);

      }

}

The overall structure of automation looks like this

Hybrid Framework: As per the definition of Hybrid Framework it’s a combination of any two frameworks hence here we have achieved the Hybrid Framework which is a combination of Modular and Data driven.
