How
to Drag and Drop in Selenium WebDriver Some web application, have a functionality to drag web
elements and drop them on defined area or element. We can automate drag and
drop of such elements using Selenium Webdriver.
Syntax for drag and drop.
The Actions class has two methods that support Drag and Drop.
Let’s study them-
Actions.dragAndDrop(Sourcelocator, Destinationlocator)In dragAndDrop method, we pass the two parameters –
- First parameter “Sourcelocator” is the element which we
need to drag
- Second parameter “Destinationlocator” is the element on
which we need to drop the first element
Actions.dragAndDropBy(Sourcelocator, x-axis
pixel of Destinationlocator, y-axis pixel of Destinationlocator)
dragAndDropBy method we pass the 3 parameters –
- First parameter “Sourcelocator” is the element which we
need to drag
- The second parameter is x-axis pixel value of the 2nd element
on which we need to drop the first element.
The
third parameter is y-axis pixel value of the 2nd element on which we need to
drop the first element.
Let’s practically show you the drag and drop of an element
using the selenium webdriver with following 3 scenarios
- Scenario 1: BANK element is dragged and dropped on the
specific element by DragAndDrop method.
- Scenario 2: BANK element is dragged and dropped on the
specific element by DragAndDrop method.
- Scenario 3: Few elements are dragged and dropped and
then verify the message is displayed or not.
Scenario 1: BANK
element is dragged and dropped on the specific cell by DragAndDrop method.
In the following code, we launch the given URL in Firefox browser
and then drag the BANK element and drop on the DEBIT SIDE block through
dragAndDrop method.
import org.openqa.selenium.By;
import
org.openqa.selenium.WebDriver;
import
org.openqa.selenium.WebElement;
import
org.openqa.selenium.chrome.ChromeDriver;
import
org.openqa.selenium.interactions.Actions;
import
org.testng.annotations.Test;
public class DragAndDrop {
WebDriver driver;
@Test
public void DragnDrop()
{
System.setProperty("webdriver.chrome.driver","
E://Selenium//Selenium_Jars//chromedriver.exe ");
driver= new ChromeDriver();
driver.get("http://demo.guru99.com/test/drag_drop.html");
//Element which needs to drag.
WebElement
From=driver.findElement(By.xpath("//*[@id='credit2']/a"));
//Element on which need to drop.
WebElement
To=driver.findElement(By.xpath("//*[@id='bank']/li"));
//Using Action class for drag and
drop.
Actions act=new Actions(driver);
//Dragged and dropped.
act.dragAndDrop(From,
To).build().perform();
Code Explanation: In the above code
we launch the given URL in Firefox browser and then drag the BANK element and
drop on the DEBIT SIDE block through dragAndDrop method. Explained briefly
below:
First, we capture the 1st element
which we need to drag in variable “From.”
WebElement
From=driver.findElement(By.xpath("//*[@id='credit2']/a"));
Second, we capture the 2nd element on which we need to drop the
1st element in variable “To”.
WebElement
To=driver.findElement(By.xpath("//*[@id='bank']/li"));
Third, we create object of Actions class as we use methods of
Actions class.
Actions act=new
Actions(driver);
For drag and drop element we use dragAndDrop
method of Actions class and passes the parameters as the first
element(Sourcelocator) “From” and the second element(Destinationlocator) “To”.
Below line will drag the 1st element and drop it on the 2nd element.
act.dragAndDrop(From, To).build().perform();
Execution of the script.
Now you can execute the above script one by one from eclipse as
shown in below screenshot.
Here is the output
when you run the script
Scenario 2: BANK
element is dragged and dropped on the specific cell by DragAndDrop method.
In this scenario, we launch the given URL in the browser and
then drag the BANK element and drop on the DEBIT SIDE block through
dragAndDropBy method. To dragAndDropBy, we need to find the pixel of the
element.
How to find
Pixel?
Open the URL in Chrome or FireFox and click on the Blue color
arrow.
Next click on any element for which you want to know the pixel.
You will find the pixel above the element as shown in below
screenshot.
import
org.openqa.selenium.By;
import
org.openqa.selenium.WebDriver;
import
org.openqa.selenium.WebElement;
import
org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
import
org.testng.annotations.Test;
public class DragAndDrop {
WebDriver driver;
@Test
public void DragnDrop()
{
System.setProperty("webdriver.chrome.driver","E://Selenium//Selenium_Jars//chromedriver.exe");
driver= new ChromeDriver();
driver.get("http://demo.guru99.com/test/drag_drop.html");
//Element(BANK) which need to drag.
WebElement
From=driver.findElement(By.xpath("//*[@id='credit2']/a"));
//Using Action class for drag and drop.
Actions act=new Actions(driver);
//Drag and Drop by Offset.
act.dragAndDropBy(From,135,
40).build().perform();
}
}
NOTE: The pixels values change with screen resolution
and browser size. This method is hence not reliable and not widely used.
Scenario 3: Few elements are dragged and dropped and then verify
the message is displayed or not.
In the following code, we launch the given URL in the browser
and then drag the elements like BANK, SALES, 500 and drop on the respective
block. Once done we verify the output message.
import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import org.openqa.selenium.interactions.Actions; import org.testng.annotations.Test; public class DragAndDrop {
WebDriver driver;
@Test
public void DragnDrop()
{
System.setProperty("webdriver.chrome.driver","
E://Selenium//Selenium_Jars//chromedriver.exe");
driver= new ChromeDriver();
driver.get("http://demo.guru99.com/test/drag_drop.html");
//Element(BANK) which need to drag.
WebElement
From1=driver.findElement(By.xpath("//*[@id='credit2']/a"));
//Element(DEBIT
SIDE) on which need to drop.
WebElement
To1=driver.findElement(By.xpath("//*[@id='bank']/li"));
//Element(SALES) which need
to drag.
WebElement
From2=driver.findElement(By.xpath("//*[@id='credit1']/a"));
//Element(CREDIT SIDE) on which need to drop.
WebElement
To2=driver.findElement(By.xpath("//*[@id='loan']/li"));
//Element(500)
which need to drag.
WebElement
From3=driver.findElement(By.xpath("//*[@id='fourth']/a"));
//Element(DEBIT SIDE) on which need to
drop.
WebElement
To3=driver.findElement(By.xpath("//*[@id='amt7']/li"));
//Element(500) which need to drag.
WebElement
From4=driver.findElement(By.xpath("//*[@id='fourth']/a"));
//Element(CREDIT SIDE) on which need to
drop.
WebElement
To4=driver.findElement(By.xpath("//*[@id='amt8']/li"));
//Using Action class for drag and drop.
Actions
act=new Actions(driver);
//BANK drag and drop.
act.dragAndDrop(From1,
To1).build().perform();
//SALES drag and drop.
act.dragAndDrop(From2,
To2).build().perform();
//500 drag and drop debit side.
act.dragAndDrop(From3,
To3).build().perform();
//500 drag and drop credit side.
act.dragAndDrop(From4,
To4).build().perform();
//Verifying the Perfect! message.
if(driver.findElement(By.xpath("//a[contains(text(),'Perfect')]")).isDisplayed())
{
System.out.println("Perfect
Displayed !!!");
}
else
{
System.out.println("Perfect
not Displayed !!!");
}
Output analysis
In Output, you can see the element is dragged and dropped on the
defined element. You can check the GIF of the output.
Summary
- In the above tutorials, we
illustrate the drag and drop functionality of the web application through
Action methods in Webdriver:
- dragAndDrop(Sourcelocator,
Destinationlocator)
- dragAndDropBy(Sourcelocator,
x-axis pixel of Destinationlocator, y-axis pixel of Destinationlocator)
- To drag and drop the element
first we used DragAndDrop method from the Actions class in which we pass
the 2 parameters, 1st parameter
is the element which we need to drag, and 2nd parameter
is the element on which we need to drop the 1st element.
- Second, we used the
dragAndDropBy method from the Actions class in which we pass the 3
parameters, the 1st parameter is the element which we need to drag, 2nd parameter is the x-axis
pixel value of the 2nd element,
3rd parameter
is the y-axis pixel value of the 2nd element
