Performing drag-and-drop operation

In Selenium WebDriver, dragAndDrop method available in Actions class. Actions class supports all advanced user interactions such as firing mouse and keyboard events on a web page.

Below is the sample logic to perform drag and drop operation on a page using Actions class.

Logic

    WebElement elementToDrag = driver.findElement(By.id("DragThis"));
    WebElement elementToDropAt = driver.findElement(By.id("DropHere"));
  
    Actions action = new Actions(driver);
    action.dragAndDrop(elementToDrag, elementToDropAt).perform();

dragAndDrop method in actions class accepts two parameters as input. One is the element to drag and another one is the destination to drop element.

Reading CSV, XLS files using java

 A CSV is a comma separated values file, which allows data to be saved in a table structured format. If we get each row stored in csv file as array we can easily get the required values using index.

There is one open-source jar to parse csv file which will make our job so simple

opencsv

opencsv is a simple CSV Parser for Java under a commercial-friendly Apache 2.0 license. Download it from below location.

OpenCSV : Download

jxl

JExcelApi is a java library which provides the ability to read, write, and modify Microsoft Excel spreadsheets.

JXL ; Download

After downloading the jars, include it in your classpath.
In Eclipsr IDE,

• Right click on project
• Build Path => Configure build path..

• Libraries => Add External jar => Select the above downloaded jar file
  
• Click Ok. Now It is ready to use in your eclipse.

Sending mail from Gmail using WebDriver

Gmail is the mostly used mail client. Here is the logic to send a mail from gmail using WebDriver.

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

import java.util.concurrent.TimeUnit;

public class SendMailFromGmail {

 
 public static void main(String[] args) {
  
  String userName="<User name>";
  String password ="<password>";
  String toAddress="san******@***.com";
  String subject="WebDriver - Selenium Testing";
  
  //Initialising driver
  WebDriver driver = new FirefoxDriver();
  
  //setting timeout for page load & implicit wait
  driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  driver.manage().timeouts().pageLoadTimeout(20, TimeUnit.SECONDS);
  
  //Call Url in get method
  driver.get("https://accounts.google.com/ServiceLogin?service=mail&continue=https://mail.google.com/mail/&hl=en");
  
  //Login
  driver.findElement(By.id("Email")).sendKeys(userName);
  driver.findElement(By.id("Passwd")).sendKeys(password);
  driver.findElement(By.id("signIn")).click();
  
  //click on Compose button
  driver.findElement(By.xpath("//div[contains(text(),'COMPOSE')]")).click();
  
  
  //enter TO address & Subject
  driver.findElement(By.xpath("//*[text()='To']/../../..//textarea")).sendKeys(toAddress);
  driver.findElement(By.name("subjectbox")).sendKeys(subject);
  
  //click Send button
  driver.findElement(By.xpath("//div[text()='Send']")).click();
  
  //Logout from Gmail
  driver.findElement(By.xpath("//a[contains(.,'"+userName+"')]")).click();
  driver.findElement(By.xpath("//div[contains(.,'Add account')]//a[contains(text(),'Sign out')]")).click();
  
 }

Browser methods in WebDriver

WebDriver, The main interface to use for testing, which represents an idealised web browser. The methods in this class fall into three categories:

1. Control of the browser itself
2. Selection of WebElements
3. Debugging aids

Key methods are get(String), which is used to load a new web page, and the various methods similar to findElement(By), which is used to find WebElements. In this post we are going to learn browser controlling methods.

get

void get(java.lang.String url)

Load a new web page in the current browser window. This is done using an HTTP GET operation, and the method will block until the load is complete. it is best to wait until this timeout is over, since should the underlying page change whilst your test is executing the results of future calls against this interface will be against the freshly loaded page.

      Usage

//Initialising driver
 WebDriver driver = new FirefoxDriver();
 
 //setting timeout for page load
 driver.manage().timeouts().pageLoadTimeout(20, TimeUnit.SECONDS);
 
 //Call Url in get method
 driver.get("https://www.google.com");
 //or
 driver.get("https://seleniumhq.org");

getCurrentUrl

java.lang.String getCurrentUrl()

Get a string representing the current URL that the browser is looking at. It returns the URL of the page currently loaded in the browser.

Usage

//Getting current url loaded in browser & comparing with expected url
 String pageURL = driver.getCurrentUrl();
 Assert.assertEquals(pageURL, "https://www.google.com");

getTitle

java.lang.String getTitle()

It returns the title of the current page, with leading and trailing whitespace stripped, or null if one is not already set.

Usage

//Getting current page title loaded in browser & comparing with expected title
 String pageTitle = driver.getTitle();
 Assert.assertEquals(pageTitle, "Google");

getPageSource

java.lang.String getPageSource()

Get the source of the last loaded page. If the page has been modified after loading (for example, by Javascript) there is no guarantee that the returned text is that of the modified page.

Usage

//get the current page source
     String pageSource = driver.getPageSource();

close

void close()

Close the current window, quitting the browser if it's the last window currently open. If there are more than one window opened with that driver instance this method will close the window which is having current focus on it.

Usage

//Close the current window
     driver.close();

quit

void quit()

Quits this driver, closing every associated window. After calling this method we can not use any other method using same driver instance.

Usage

//Quit the current driver session / close all windows associated with driver
     driver.quit();

These are all very useful methods available in Selenium 2.0 to control browser as required.
