TestNG Annotations in Selenium

TestNG :

TestNG is an automation framework mostly used in Selenium automation scripts for Web applications.It is very important to understand the annotations while working with TestNG for Selenium WebDriver. Testng providing suitable annotations to prepare Test scripts in Selenium WebDriver where you can pass test data from different files such as Excel,XLS files and You can run the scripts before tarting the class Method etc.

TestNG Annotations in Selenium

TestNG has below annotations those are

1. BeforeSuite 
2. AfterSuite 
3. BeforeTest 
4. AfterTest
5. BeforeGroups
6. AfterGroups 
7. BeforeClass
8. AfterClass
9. BeforeMethod 
10. AfterMethod 

You can read TestNG Tutorials from Here

Explanation:

@BeforeSuite: This annotation method will be run before all tests in this Test suite have to run.

@After Suite: This annotated method will be run after all tests in this Test suite have to run.

@BeforeTest: This annotated method will run before any test method which is belongs to the classes inside the test tag.

@After Test: This annotated method will be run after all the test method which is belongs to the classes inside the test tag have to run.

@BeforeClass: This annotated method will run before the first test method in the current class is invoked.

@After Class: This annotated method will be run after all the test methods in the current class have run.

@BeforeMethod : This annotated method will be run before each test method.

@AfterMethod: This annotated method will be run after each test method.

Example:

Before Test Selenium Web Driver will initiate and run the Tests in classes.

package com.fs.msn.automate;
import java.io.File;
import java.io.IOException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.BeforeTest;

public class SeleniumWebDriv {
 public static WebDriver driver=null;  
 public String baseUrl;
 
   @BeforeTest public void BeforeTests () throws IOException{ 
   
  //Import Chrome extension from Local machine   
 File ChromeDriver = new File("D:\\Rajesh\\2014\\Java_Applications\\Zip Files\\chromedriver.exe");     
 //Set Chrome driver property    
 System.setProperty("webdriver.chrome.driver", ChromeDriver.getAbsolutePath());
 
    driver = new ChromeDriver();    
 driver.manage().window().maximize();    
 baseUrl="http://www.wikishown.com";   
 driver.get(baseUrl);      
 }
}

How to read data from excel using Selenium

We have know that Selenium is using for Web application testing and Browser testing.

Today we are learning how to read data from excel using Selenium.In order to perform this action we need to download third party APIs for excel to load into Selenium.For this we are using jxl.jar file for Excel operations in Selenium.

Please download jxl jar from this download jar

Steps to create script.

1.Create project
2.Create Package
3.Create Class
4.Associate library files to project
5.Create the Excel sheet with data,for example i am using Gmail login.Please fine the below

6.Start the Selenium Server
7.Create the below script

package com.Gmail.Login;

import static org.junit.Assert.*;

import java.io.FileInputStream;
import java.io.IOException;
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.server.SeleniumServer;
import com.thoughtworks.selenium.DefaultSelenium;
import com.thoughtworks.selenium.SeleneseTestCase;

@SuppressWarnings({ "unused", "deprecation" })
public class Gmaillogins extends SeleneseTestCase{

   @Before
   public void setUp() throws Exception {
       SeleniumServer ss=new SeleniumServer();
       ss.start();
       selenium=new DefaultSelenium("localhost",4444,"firefox", "http://www.gmail.com");
       selenium.start();
   }

   @After
   public void tearDown() throws Exception {
   }

   @Test
   public void test() throws BiffException, IOException, InterruptedException {
       selenium.open("/");
       selenium.windowMaximize();
       FileInputStream fis=new FileInputStream("D:\\2014\\Java_Applications\\gmail_login.xls");
       Workbook wb=Workbook.getWorkbook(fis);
       Sheet s=wb.getSheet(0);
       selenium.type("id=Email",s.getCell(0,1).getContents());
       selenium.type("id=Passwd",s.getCell(1,1).getContents());
       Thread.sleep(3500);
   }

}

8.Save the script

9.Run the script

How to create data driven framework using selenium

Selenium Automated software tools on the market supports data driven testing, which allows software to automatically run a tests multiple times with multiple inputs and validations.Selenium is used to automate the software with data driven testing framework where we can use Excel sheets.

Below Script provide details about simple data driven testing using Excel sheet.

Steps:

Download apache POI jar files and add jars to project library in Eclipse

Selenium Script

Selenium Data Driven testing

package com.selenium.pack;

import java.io.FileInputStream;

Selenium Tutorials Assertions in Selenium

---

For verifying in selenium we have two verification points ,those are

• Assert
• Verify
• WaitFor
• Assert:If the test case pass it will go to the next test case and if the test case is fail then it will stop execution.
• Verify:If the test cases pass or fail it will execute all the test cases at end of execution it eill display result.
• WaitFor:WaitFor command is used to wait upto some extend to enable some condition to become enable.

Asserts

• Assert Text Present:Verify the text on where ever in web page
• Assert text:Verify the location of text
• Assert Title:Verify the page title
• Assert Element Present:Verify the element is present in web page

Assertions/Verify commands in Selenium IDE While Recording

• Open Selenium IDE
• Enter URL in Base URL of IDE
• Enter same url in Firefox browser
• Click on Enter
• Right click on any where on page
• You will see available commands according to below screen.
