Reading a Table in Selenium Wedriver

Reading Data from the table is somewhat different from accessing normal elements from the webpages.Because generally developers when develop the html page they provide id,name etc.But for table they don't provide any id, name etc.So we generally go with XPath.

How to Take ScreenShot on Failure Testcases in Selenium WebDriver

Examples:

package Screenshotexp;

import java.io.File;

import org.apache.commons.io.FileUtils;

import org.openqa.selenium.Alert;

import org.openqa.selenium.By;

import org.openqa.selenium.OutputType;

import org.openqa.selenium.TakesScreenshot;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.testng.ITestResult;

import org.testng.annotations.AfterMethod;

import org.testng.annotations.Test;

public class googleScreenshot {

WebDriver driver;

@Test

public void googleScreenShot()

{

driver=new FirefoxDriver();

driver.get("https://www.google.co.in");

driver.manage().window().maximize();

//we have given wrong xpath intentionally.so test case fails

driver.findElement(By.xpath("//*[@id='gs_htif']")).sendKeys("Selenium");

}

//After Method always execute 

@AfterMethod

public void tearDown(ITestResult result)

{ 

//ITestResult.FAILURE for failed testcases

if(ITestResult.FAILURE==result.getStatus())

{

try{

 File screenshot=((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);

 

 //result.getname() will get testcase name and save same file for screenshot which is taken

 FileUtils.copyFile(screenshot, new File("./Screenshots/"+result.getName()+".png"));

 System.out.println("Screenshot taken");

}catch(Exception e)

{

System.out.println("Unable to  take screen shot:"+e.getMessage());

}

driver.quit();

}

}

}

Output:

Screenshot taken

Handling Multiple Windows in Selenium Webdriver

Multiple Windows:

Multiple window handling in selenium webdriver is done by using "getWindowHandle()" is for the parent window and "getWindowHandles()" is for multiple child window handling.We have to switch window from parent (or) main window to child window.

• Below i have given the html sample code also for the below program.
• save that html code by .html extension and pass that path in driver get method.

import java.util.Set;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.Test;

public class multiplewindow {

@Test
public void mulwindows() throws InterruptedException
{

WebDriver driver=new FirefoxDriver();
driver.get("H:\\websites.html");
driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
System.out.println("Parent window title is:"+driver.getTitle());

               //get window handle method is used and stored in variable for further refernces.
String parent_window=driver.getWindowHandle();


driver.findElement(By.linkText("google")).click();

     
              //Gets all the links present in main window and its return type is Set of strings.
Set<String> allwindows=driver.getWindowHandles();



for(String child_window:allwindows)
{

if(!child_window.equals(parent_window))
{

                              //Switching from parent window to child window
driver.switchTo().window(child_window);

System.out.println("Title is:"+driver.getTitle());

driver.findElement(By.className("gsfi")).sendKeys("selenium");

}

}

driver.close();

                      //Switching back to parent window.
driver.switchTo().window(parent_window);

Thread.sleep(3000);
driver.quit();


}

}


Output:

Parent window title is: mulwindow
Title is:Google

PASSED: mulwindows

HTML Code:

<!DOCTYPE html>

<html>

<body>

<title>mulwindow</title>

<p><a href="http://www.google.com" target="_blank">google</a></p>

<p><a href="http://www.flipkart.com"target="_blank">flipkart</a></p>
