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.

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.

Program to remove duplicate numbers

Write a program to remove duplicate numbers from given array.

public class RemoveDuplicateNumbers {

  public static void main(String a[]){
         int[] input1 = {2,3,6,6,8,9,10,10,10,12,12};
         int[] output = removeDuplicates(input1);
         for(int i:output){
             System.out.print(i+" ");
         }
     }

 private static int[] removeDuplicates(int[] input) {
   int j = 0;
         int i = 1;
         //return if the array length is less than 2
         if(input.length < 2){
             return input;
         }
         while(i < input.length){
             if(input[i] == input[j]){
                 i++;
             }else{
                 input[++j] = input[i++];
             }    
         }
         int[] op = new int[j+1];
         for(int k=0; k<op.length; k++){
             op[k] = input[k];
         }
         return op;
 }
}

Write a program to remove duplicate characters from array

public class RemoveDuplicateChars {

 public static void main(String[] args) {
  char c[]={'a','b','g','c','d','e','a','f','c','g'};
  RemoveDuplicateChars obj = new RemoveDuplicateChars();
  obj.method1(c);
 }

 public void method1(char a[]) {
  String s=new String(a);
  String temp="";
  for(int i=0;i<s.length();i++) {
   String s1=s.substring(i, i+1);
   if(temp.contains(s1)) {
    continue;
   } else {
    temp+=s1;
   }
  }
  System.out.println(temp);
 }
}

Checking text on web page using WebDriver

While testing any web application, we need to make sure that it is displaying correct text under given elements. Selenium WebDriver provides a method to achieve this. We can retrieve the text from any WebElement using getText() method.

Example
Lets create a test that check for the proper text in flipkart menu tab.

Code:

@Test
public void testFlipkartMenuText() {
    //Get Text from first item and store it in String variable
    String electronics = driver.findElement(By.cssSelector("li[data-key='electronics']>a>span")).getText();

    //Compare actual & required texts
    assertEquals("Electronics",electronics);  
}

The WebElement class' getText() method returns value of the innerText attribute
of the element.

P.S : Given script may not work on flipkart site. I've written this code just to give some basic idea of using getText() method.

Locating elements using findElements methods

Selenium WebDriver provides the findElements() method, which returns List of WebElements with matching criteria. This method is useful when we want to do some operation with each element with same locator.

Examples

• Get all links on a page
• Get all buttons on page
• Get all options from dropdown
• Get all rows in table and td s from tr 

Let's create a test to check no of rows in given table.

@Test
public void testFindElements() {
  //Get all the tr from table
  List allTrs = driver.findElements(By.cssSelector("table[id='myContacts'] tr"));

  //verify there are 3 trs under given table
  assertEquals(3,allTrs.size());

  //Iterate all tr tags and print no of td tags in each tr tag
  for(WebElement eachTr : allTrs) {
    System.out.println(eachTr.findElements(By.tagName("td")).size());
  }
}

WebDriver Interview Questions - III

Create and Delete Cookies with Selenium IDE

Create Cookie

Cookies can be created in Selenium-IDE using createCookie Method.

createCookie(nameValuePair, optionsString)
    Arguments:

   nameValuePair - name and value of the cookie in a format "name=value"

   optionsString - options for the cookie. Currently supported options include 'path', 'max_age' and 'domain'. the optionsString's format is "path=/path/, max_age=60, domain=.foo.com". The order of options are irrelevant, the unit of the value of 'max_age' is second. Note that specifying a domain that isn't a subset of the current domain will usually fail.

    Create a new cookie whose path and domain are same with those of current page under test, unless you specified a path for this cookie explicitly.

Delete Cookie

Cookies can be deleted in Selenium-IDE using deleteCookie Method.

deleteCookie(name, optionsString)
    Arguments:

     name - the name of the cookie to be deleted

    optionsString - options for the cookie. Currently supported options include 'path', 'domain' and 'recurse.' The optionsString's format is "path=/path/, domain=.foo.com, recurse=true". The order of options are irrelevant. Note that specifying a domain that isn't a subset of the current domain will usually fail.

    Delete a named cookie with specified path and domain. Be careful; to delete a cookie, you need to delete it using the exact same path and domain that were used to create the cookie. If the path is wrong, or the domain is wrong, the cookie simply won't be deleted. Also note that specifying a domain that isn't a subset of the current domain will usually fail. Since there's no way to discover at runtime the original path and domain of a given cookie, we've added an option called 'recurse' to try all sub-domains of the current domain with all paths that are a subset of the current path. Beware; this option can be slow. In big-O notation, it operates in O(n*m) time, where n is the number of dots in the domain name and m is the number of slashes in the path.

Selecting options from dropdown using partial text

    Selecting option(s) from dropdown is the one of the more frequent action while automating web application.

  I've written already detailed post for usage of Select class available in WebDriver. You can find that here.

 Here I'm going to write how to choose options using partial text or partial values.

HTML CODE
      <select id="city">
             <option value="City: Chennai">Chennai</option>
             <option value="City: Hyd">Hyderabad</option>
             <option value="City: Blore">Bangalore</option>
     </select>

Choose option using partial & full value

Select Chennai using its partial value.

driver.findElement(By.id("city")).findElement(By.cssSelector("option[value*='Chennai']")).click();

Select Chennai using its value

new Select(driver.findElement(By.id("city"))).selectByValue("City: Chennai");

Choose option using partial & full Text

Select Hyderabad using its partial text.

driver.findElement(By.id("city")).findElement(By.xpath("//option[contains(text(),'Hyd')]")).click();

Select Hyderabad using its text

new Select(driver.findElement(By.id("city"))).selectByVisibleText("Hyderabad");

WebElement & Locators

Scroll Function in WebDriver

Sometimes we would like to scroll webpage to particular WebElement or press Keyboard DOWN button to scroll the page. We can achieve scroll pages with below code snippets. 

Scrolling Using javascript

Code :

       WebElement ele = driver.findElement(By.id("test"));

       ((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView()",ele);

Using Actions Class

package name  : org.openqa.selenium.interactions.Actions

java code :

                          Actions action=new Actions(driver);

                          action.sendKeys(Keys.DOWN).perform();

Without Using Actions Class

java code :

                     driver.findElement(By.tagName("body")).sendKeys(Keys.DOWN);

WebElement & Locators

Executing javascript using WebDriver

  You can execute required javascript call using WebDriver in your automation code using JavaScriptExecutor.

Example

• you may want to fire an event on a particular element. (calling blur event directly)
• you may want to execute some script which will do some other operation. (instead of clicking directly call onclick targeted script)

Steps

• Cast the WebDriver instance to JavaScriptExecutor 
• Execute the script using executeScript() method

Logic

WebDriver driver = new FirefoxDriver();

JavaScriptExecutor js=(JavaScriptExecutor)driver;  //casting driver instance

String title=(String)js.executeScript("return document.title");  //for getting window tile

String name=(String)js.executeScript("return window.name");  //for getting window name

js.executeScript("$('#elementId').blur()");  //firing blur event on an element

executeScript() will return java.lang.Object, from that you can get your required data.

 While returning values from the JavaScript code, need to use the return keyword. Based on the type of return value, need to type cast the executeScript() method.

• For decimal values, Double can be used, 
• for non-decimal numeric values Long can be used,  
• for Boolean values Boolean can be used. 
• JavaScript code is returning an HTML element, then WebElement can be used. 
• For text values, String can be used. 
• If a list of objects is returned, then any of the values will work based on type of objects. Otherwise, a null will be returned.

Browser Navigation Using WebDriver

Browser Navigation.


Do you want to automate any browser action (Ex: forward, back, refresh) using WebDriver ?

Cases where we need this type of operations

• You need to verify your web-application going to previous page if you click on browser back button.
• Sometimes you may want to refresh the browser to complete some action.

Its pretty simple with WebDriver. Here is the logic to do browser navigation operations.

//TO perform browser back button action

driver.navigate().back();

//TO perform browser forward button action

driver.navigate().forward();

//To refresh bowser

driver.navigate().refresh();

//To navigate to particular URL

driver.navigate().to("url");

//You can give url in String or java.net.URL url format

I hope this would be helpful for beginners.

Handling JavaScript alerts using WebDriver

   It is very simple to handle javascript alerts in WebDriver. If we don't handle the alerts properly WebDriver will throw UnhandledAlertException .


  In web application mostly we see two types of pop-ups, 1. alerts 2. confirm popup

  Handling both alerts & confirms popup WebDriver has a Alert interface. Using WebDriver you can click on OK or Cancel button and also can get alert message also to verify.

Logic 

//First we need switch the control to alert.

       Alert alert = driver.switchTo().alert();

//Getting alert text

       alert.getText();

//Click on OK

       alert.accept();

//Click ok Cancel

      alert.dismiss();

I hope this would help you to handle javascript alerts.

Happy coding :)

   In automation locating web elements in DOM is one of the important task. In DOM, if all the elements have unique ids then no problem but, if not we need to go for xpath for locating elements in DOM.

  Say for example generally we don't see any ids for the table rows & columns, in that case we need to locate table data using some other attributes. Ex: name, position, innerText.

  Below I'm writing simple example to understand the different options available in xpath. (Place mouseover the locator to see which element it will locate in table)

HTML Elements

Above html in browser

One		Bike
Two		Car
Three		Bus
Four		Jeep

Locating elements using Attributes

Attribute	Usage
id	By.xpath("//table[@id='tableId']")
id	By.xpath("//td[@id='car']")
name	By.xpath("//td[@name='Chk3']")

Locating Rows using index

Row	As a child	As a sub-child
1	By.xpath("//table[@id='tableId']/tbody/tr[1]")	By.xpath("//table[@id='tableId']//tr[1]")
2	By.xpath("//table[@id='tableId']/tbody/tr[2]")	By.xpath("//table[@id='tableId']//tr[2]")
3	By.xpath("//table[@id='tableId']/tbody/tr[3]")	By.xpath("//table[@id='tableId']//tr[3]")
4	By.xpath("//table[@id='tableId']/tbody/tr[4]")	By.xpath("//table[@id='tableId']//tr[4]")

Locating Rows using functions

Function	As a child
position()	By.xpath("//table[@id='tableId']//tr[position()=1]")
position()	By.xpath("//table[@id='tableId']//tr[position()=3]")
last()	By.xpath("//table[@id='tableId']//tr[last()]")
last()	By.xpath("//table[@id='tableId']//tr[last()-1]")

Locating Rows using String functions

Function	Usage
text()	By.xpath("//table[@id='tableId']//tr/td[text()='One']")
contains()	By.xpath("//table[@id='tableId']//tr/td[contains(text(),'hre')]")
starts-with()	By.xpath("//table[@id='tableId']//tr/td[start-with(text(),'Fo')]")

Locating Columns using Xpath Axes

Axes	Usage
child	By.xpath("//table[@id='tableId']//tr/child::td[text()='One']")
parent	By.xpath("//td[@id='car']/parent::tr")
preceding-sibling	By.xpath("//td[contains(@id,'bus')]/preceding-sibling::td/input")
following-sibling	By.xpath("//td[text()='Four']/following-sibling::td[@id='jeep']")

• Child : Selects all children of the current node.
• Parent : Selects the parent of the current node.
• preceding-sibling:Selects all siblings before the current node.
• following-sibling:Selects all siblings after the current node.

Happy Coding :)

Generating Random Data

Say , you are running RecordCreate/FormFilling automation for 100 times.

1. Passing every time same values (Hardcoded values)
2. Passing randomly generated values from allowed characters

Which one is more reliable ? 

How will you verify forms by filling allowed max length values ?

Let's see how to fill the forms in web application with random & specified length values.

Consider below form

You want to fill below form with randomly generated values with specified lengths.

Register here

First Name
Last Name
Email
Phone
Income

See below testcase to know how can we pass random & specified length values to different fields.

RegistrationForm.java

package com.test.registration;

import static org.junit.Assert.assertEquals;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

import com.test.general.GenerateData;

public class RegistrationForm {
 
 WebDriver driver;
 GenerateData genData;
 
 @Before
 public void before(){
  driver=new FirefoxDriver();
  genData=new GenerateData();
 }
 
 @Test
 public void testRegistrationForm() {
  driver.findElement(By.id("f_name")).sendKeys(genData.generateRandomAlphaNumeric(30));    
  driver.findElement(By.id("l_name")).sendKeys(genData.generateRandomString(20));
  driver.findElement(By.id("email")).sendKeys(genData.generateEmail(30));
  driver.findElement(By.id("skype")).sendKeys(genData.generateStringWithAllobedSplChars(30, "abc123_-."));
  driver.findElement(By.id("phone")).sendKeys(genData.generateRandomNumber(10));
  driver.findElement(By.id("income")).sendKeys(genData.generateRandomNumber(9));
  driver.findElement(By.id("submit")).click();
  assertEquals("Success", driver.getTitle());
 }
 
 @After
 public void after(){
  driver.quit();
 }

}

GenerateData.java

package com.test.general;

import org.apache.commons.lang3.RandomStringUtils;

public class GenerateData {

 public String generateRandomString(int length){
  return RandomStringUtils.randomAlphabetic(length);
 }
 
 public String generateRandomNumber(int length){
  return RandomStringUtils.randomNumeric(length);
 }
 
 public String generateRandomAlphaNumeric(int length){
  return RandomStringUtils.randomAlphanumeric(length);
 }
 
 public String generateStringWithAllobedSplChars(int length,String allowdSplChrs){
  String allowedChars="abcdefghijklmnopqrstuvwxyz" +   //alphabets
    "1234567890" +   //numbers
    allowdSplChrs;
  return RandomStringUtils.random(length, allowedChars);
 }
 
 public String generateEmail(int length) {
  String allowedChars="abcdefghijklmnopqrstuvwxyz" +   //alphabets
    "1234567890" +   //numbers
    "_-.";   //special characters
  String email="";
  String temp=RandomStringUtils.random(length,allowedChars);
  email=temp.substring(0,temp.length()-9)+"@test.org";
  return email;
 }
 
 public String generateUrl(int length) {
  String allowedChars="abcdefghijklmnopqrstuvwxyz" +   //alphabets
    "1234567890" +   //numbers
    "_-.";   //special characters
  String url="";
  String temp=RandomStringUtils.random(length,allowedChars);
  url=temp.substring(0,3)+"."+temp.substring(4,temp.length()-4)+"."+temp.substring(temp.length()-3);
  return url;
 }
}
 

    While doing web application automation make a habit of passing random data with different lengths (<= Allowed max length) every time to improve reliability.
