How To Select Date From Calendar in Selenium WebDriver using Jquery | Handle Date Time Picker Using Selenium WebDriver

In this tutorial, I am going to explain how to select a date from a calendar of any websites.




Handle Date Time Picker In Selenium



how-to-handle-calender-using-selenium-webdriver



We often observe Date Time Picker fields on the websites mostly on E-Commerce and Travel Booking websites. Different websites use the Date Time Picker field/Calendar having different UI, but the functionality is the same. So in this tutorial, we will learn how to handle Date Time Picker field/Calendar using Selenium WebDriver.

There may be different ways to handle such a scenario. But here I will explain just one way that will cover any type of Date Time Picker field of any websites. I will use just one line of code that will handle the scenario. I will use the concept of JavaScript Executor(JQuery).

We will take 'Yatra' website to demonstrate the scenario.


 package com.sessions;  
   
 import org.openqa.selenium.JavascriptExecutor;  
 import org.openqa.selenium.WebDriver;  
 import org.openqa.selenium.chrome.ChromeDriver;  
   
   
 public class CalendarTest {  
   
      public static void main(String[] args) {  
             
           System.setProperty("webdriver.chrome.driver", "F:\\software\\chromedriver_win32\\chromedriver.exe");  
             
           WebDriver driver = new ChromeDriver();  
             
           driver.get("http://www.yatra.com/");  
             
           driver.manage().window().maximize();  
             
           //Typecating driver as a JavascriptExecutor and assigning it to the variable of JavascriptExecutor  
           JavascriptExecutor js = (JavascriptExecutor )driver;  
             
           //Putting date to the the selected date picker.  
           js.executeScript("document.getElementById('BE_flight_origin_date').value='03/10'");  
   
      }  
   
 }  
   


Explanation

  • Javascript Executor is an Interface provided by Selenium WebDriver which is used to run Javascript commands from Selenium script.
  • This Interface provides a method executeScript() - to run the Javascript commands.
  • We need to import one package called org.openqa.selenium.JavascriptExecutor.
  • Since the driver can execute only selenium commands so we need to typecast driver as a JavascriptExecutor so that Javascript commands can be run from Selenium script.  
  • document.getElementById('BE_flight_origin_date').value='03/10'
Here, getElementById('value of the Id attribute') is used to locate element (date picker field) on the webpage using ID attribute and then we are setting date value to the field. We can inspect and get the Id attribute as we do in Selenium.

In case you do not know how to inspect element, follow the link - Inspect Element In Selenium



Note - Before setting the date value, first verify in which format the field is accepting the date value. Based on the format provide the value in the script. In our case format is - '03/10'.


As I said just one line of code and everything is done!!!


General Steps
  1. Define JavascriptExecutor interface variable and typecast the driver.
  2. execute the command by locating the date picker field using its Id attribute and set the value based on the acceptable date format.


That's all guys!!! Do comment and post your doubts related to Selenium!!!

Top 10 Selenium Interview Questions And Answers - Part 1


Hello guys, In this blog I am going to provide most frequently asked selenium-related interview questions and answers in part-wise.




Part 1


1. How to handle dynamic elements in Selenium?

Solution – We can use x-path along with contains(), starts-with(), ends-with() methods –   
                    depends on the scenario.     

Example

Let’s say, ‘Id’ of a username field is – username_123
If you open the page again, then Id is showing as - username_245

That’s mean, the first part – username is static, whereas, second part after underscore is dynamic.

x-path for such scenario will be =  //*[contains(@id ,’username’)]

Since the starting text is static, the above scenario can also be handled using starts-with() method.

x-path = //*[starts-with(@id ,’username_’)]


Let’s say, ‘Id’ of a username field is – 123_username
If you open the page again, then Id is showing as – 245_username

Here the latter part is static.

X-path = //*[ends-with(@id ,’_username’)]


2.  Give an example of Method overloading in Selenium.

Solution -  Example can be switching to Frames.

·         frame(int index)
·         frame(string frame_name)
·          frame(WebElement element)


1   3.  How do you achieve synchronization in Selenium?
S
S   Solution – driver.manage().timeOuts().implicitlyWait(10, OutputType.SECONDS);
It 
il      It will ask the web driver to wait for 10 seconds before throwing an exception in case any web driver is unable to locate any element. It is applicable to every command written in the script.


1
   4. How to invoke an application in web driver?

S   Solution –

·         driver.get(“application_url”);

·         driver.navigate().To(“application_url”);


1  5. How to get the width and height of the textbox?
     Solution –

·         driver.findElement(By.xpath(“locator”)).getSize().getWidth();
·         driver.findElement(By.xpath(“locator”)).getSize().getHeigtht();



  
    6. Difference between Assert, Verify and WaitFor commands.
S
o   Solution –

·         Assert – It checks whether an element is on the page or not. If the element is not present, then the test will fail, and execution will stop at that point only.
·         Verify - It checks whether an element is on the page or not. If the element is not present, then the test will fail, but execution will continue until the last command of the script.
·         WaitFor – It waits for the specified amount of time so that the element may be available on the page. But if the element is not available within the specified amount of time, then the test will fail at that point only.


7.  Different ways to refresh the browser.

S     Solution –

·         Driver.navigate().refresh();
·         Driver.navigate().to(driver.getCurrentUrl());
·         Driver.get(driver.getCurrentUrl());



1  8. Different exceptions encountered in Selenium WebDriver.
S
S    Solution -  Below are some most encountered Exceptions that occur while creating Selenium Automation Script.

  •     NoSuchFrameException
  •     AlertNotPresentException. 
  •     NoSuchElementException.
  •     ElementNotVisibleException.
  •      NOSuchWindowException.
  •       TimeOutException.
         
         To get a detailed explanation, follow the linkExceptions In Selenium


    9. What is the alternate way to click on the Login button?

S   Solution –

                    submit() – But can be used only when attribute ‘type=submit’.

1
    10. What is the purpose of getOptions() methods?
S    
o      Solution – It is used to get all the selected options from the dropdown list.

                             Return Type -  List<WebElement>

       
      Below program will print all the options of the Country drop-down


 package com.javascript;  
   
 import java.util.List;  
   
 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.support.ui.Select;  
   
 public class GetOption {  
   
      public static void main(String[] args) {  
             
           System.setProperty("webdriver.chrome.driver", "F:\\software\\chromedriver_win32\\chromedriver.exe");   
            WebDriver driver = new ChromeDriver();   
            driver.get("http://newtours.demoaut.com/mercuryregister.php");   
            driver.manage().window().maximize();  
              
            Select select = new Select(driver.findElement(By.xpath("//select[@name='country']")));  
            List<WebElement> options = select.getOptions();  
            for(WebElement option : options)  
            {  
                 System.out.println(option.getText());  
            }  
              
   
      }  
   
 }

Actions in Selenium | Keywords And Mouse Events Using Actions Class In Selenium WebDriver

In this tutorial, I am going to cover how to handle keyboard and mouse events using Actions classes in Selenium.




Topics to be covered
  • What is Keyboard and Mouse events?
  • Actions class in Selenium.
  • How to handle different keyboard and mouse events using Actions class in Selenium?



Actions 







There are various kinds of Keyboard and Mouse events such as - 
  • Drag and drop.
  • Right click.
  • Double click.
  • MouseOver.
and so on.

Such events are handled using advanced user interactions APIs. It contains Action and Actions classes to handle such events.

In Selenium, we will use Actions class to perform such events while automating.

In order to use Actions class, we need to import one package

 org.openqa.selenium.interactions.Actions;  


We will use the Mercury Tours application to demonstrate keyboard and mouse events.






#1 MouseOver - In this event, only the mouse is moved over a web-element but not clicked.

To handle MouseOver, Actions class provides a method

  • movetoElement(WebElement element); -> element indicates on which element MouseOver will be performed.
Note - moveToElement() will just inform that on which element mouseOver will be done. It will not move the mouse over that element.

To achieve it, Actions provides two methods- 
  • perform() - It completes an action which is intended to achieve. It is used when the user wants to perform a single action.
  • build() - If the user wants to perform multiple actions on an element at a time, it is used. It compiles all the actions as a single one. It is followed by perform() methods.

-> These two methods are applicable to all the events mentioned above. 

-> We will get a clear picture when we do programming.


 package com.sessions;  
   
 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;  
   
 public class keyboard_Mouse_Events {  
   
      public static void main(String[] args) {  
           System.setProperty("webdriver.chrome.driver", "F:\\software\\chromedriver_win32\\chromedriver.exe");  
             
           WebDriver driver = new ChromeDriver();  
             
           driver.get("http://newtours.demoaut.com/");  
             
           driver.manage().window().maximize();//maximizing browser.  
             
           //Creating Actions Class Object  
           Actions act = new Actions(driver);  
             
           //Locating the element to perform mouse over.  
           WebElement element = driver.findElement(By.xpath("//input[@name='login']"));  
             
           //Performing mouse over on the element.  
           act.moveToElement(element).perform();  
             
           }  
   
 }  
   


Explanation - 
  • In this program, We are performing mouse over on the 'Login' button of Mercury Tours application highlighted in the above image.
  • 'element' variable is pointing to the 'Login' button.
  • We have used perform() method as we are performing only single action.
  • Since it is just doing mouse over operation on the 'Login' button. So we can't visualize it.



#2 Right Click - This event performs a right-click operation as we normally do with the mouse.

->Actions class provides two methods to achieve it - 

  • contextClick(WebElement element); --> element indicates on which element Right-Click will be performed.
  • contextClick(); --> To perform right-click operation on the web-page.


 package com.sessions;  
   
 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;  
   
 public class keyboard_Mouse_Events {  
   
      public static void main(String[] args) {  
           System.setProperty("webdriver.chrome.driver", "F:\\software\\chromedriver_win32\\chromedriver.exe");  
             
           WebDriver driver = new ChromeDriver();  
             
           driver.get("http://newtours.demoaut.com/");  
             
           driver.manage().window().maximize();//maximizing browser.  
             
           //Creating Actions Class Object  
           Actions act = new Actions(driver);  
             
           //Locating the element to perform right-click.  
           WebElement element = driver.findElement(By.xpath("//input[@name='login']"));  
             
           //Performing right-click action on the element.  
           act.contextClick(element).perform();  
             
             
           }  
   
 }  
   


Explanation - 
  • In this program, We are performing right-click on the 'Login' button of Mercury Tours application highlighted in the above image.
  • 'element' variable is pointing to the 'Login' button.
  • We have used perform() method as we are performing only single action.



#3 Double Click - This event performs a double-click operation as we normally do with the mouse.

->Actions class provides two methods to achieve it - 

  • doubleClick(WebElement element); --> element indicates on which element double-Click will be performed.
  • doubleClick(); --> To perform double-click operation on the web-page.

 package com.sessions;  
   
 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;  
   
 public class keyboard_Mouse_Events {  
   
      public static void main(String[] args) {  
           System.setProperty("webdriver.chrome.driver", "F:\\software\\chromedriver_win32\\chromedriver.exe");  
             
           WebDriver driver = new ChromeDriver();  
             
           driver.get("http://newtours.demoaut.com/");  
             
           driver.manage().window().maximize();//maximizing browser.  
             
           //Creating Actions Class Object  
           Actions act = new Actions(driver);  
             
           //Locating the element to perform double-click.  
           WebElement element = driver.findElement(By.xpath("//font[text()='Password:']"));  
             
           //Performing double-click action on the element.  
           act.doubleClick(element).perform();  
             
             
           }  
   
 }  
   









Explanation - 
  • In this program, We are performing double-click on the 'Password' text of Mercury Tours application highlighted in the above image.
  • 'element' variable is pointing to the 'Password' text.
  • We have used perform() method as we are performing only single action.
  • After performing the action, 'Password' text will be highlighted in blue.



#4 Drag And Drop - This event drags one element from the source location and drops it to the target location.

->Actions class provides two ways to achieve it -

  1. clickAndHold(source_element).moveToElement(target_element).release().build().perform();
  2. dragAndDrop(source_element,target_element);

First Approach - 

 package com.sessions;  
   
 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.openqa.selenium.support.ui.ExpectedConditions;  
 import org.openqa.selenium.support.ui.WebDriverWait;  
   
 public class keyboard_Mouse_Events {  
   
      public static void main(String[] args) {  
           System.setProperty("webdriver.chrome.driver", "F:\\software\\chromedriver_win32\\chromedriver.exe");  
             
           WebDriver driver = new ChromeDriver();  
             
           driver.get("https://jqueryui.com/droppable/");  
             
           driver.manage().window().maximize();//maximizing browser.  
             
           //Creating Actions Class Object  
           Actions act = new Actions(driver);  
             
           //Waiting for the frame to be available and switching to it.  
           WebDriverWait wait = new WebDriverWait(driver,10);  
           WebElement frame= driver.findElement(By.xpath("//iframe[@class='demo-frame']"));  
           wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(frame));  
             
           //Locating the element to drag.  
           WebElement drag_element = driver.findElement(By.xpath("//div[@id='draggable']"));  
             
           //Locating the element to drag.  
           WebElement drop_element = driver.findElement(By.xpath("//div[@id='droppable']"));  
             
           //Performing drag and drop  
           act.clickAndHold(drag_element).moveToElement(drop_element).release().build().perform();  
             
           }  
   
 }  
   






Explanation - 
  • In this program, We are performing drag and drop operation as shown in the above image.
  • These drag and drop elements are available under a frame. So we first switched to the frame by locating it. We waited for the frame to be available then switched to it.
  • 'drag_element' variable is pointing to the element to be draggable.
  • 'drop_element' variable is pointing to the element to be droppable.
  • We have used build().perform() method as we are performing three operations.
  • clickAndHold() -> It will click on the source element and hold it.
  • moveToElement() -> It will move the hold element to the specified target element.
  • release() -> It will release the hold element to the target element.



Second Approach  -

 package com.sessions;  
   
 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.openqa.selenium.support.ui.ExpectedConditions;  
 import org.openqa.selenium.support.ui.WebDriverWait;  
   
 public class keyboard_Mouse_Events {  
   
      public static void main(String[] args) {  
           System.setProperty("webdriver.chrome.driver", "F:\\software\\chromedriver_win32\\chromedriver.exe");  
             
           WebDriver driver = new ChromeDriver();  
             
           driver.get("https://jqueryui.com/droppable/");  
             
           driver.manage().window().maximize();//maximizing browser.  
             
           //Creating Actions Class Object  
           Actions act = new Actions(driver);  
             
           //Waiting for the frame to be available and switching to it.  
           WebDriverWait wait = new WebDriverWait(driver,10);  
           WebElement frame= driver.findElement(By.xpath("//iframe[@class='demo-frame']"));  
           wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(frame));  
             
           //Locating the element to drag.  
           WebElement drag_element = driver.findElement(By.xpath("//div[@id='draggable']"));  
             
           //Locating the element to drag.  
           WebElement drop_element = driver.findElement(By.xpath("//div[@id='droppable']"));  
             
           //Performing drag and drop  
           act.dragAndDrop(drag_element, drop_element).build().perform();  
             
           }  
   
 }  
   


Explanation -

  • dragAndDrop(source, target) -> It will drag the specified source element and drop it to the specified target element.
