HCL – Selenium Interview Questions

Here is the list of Selenium Interview Questions which are recently asked in HCL company. These questions are included for both Freshers and Experienced professionals. Our Selenium Training has Answered all the below Questions.

1. Explain the Framework you are using

• Data-Driven Test Framework
• Keyword Driven Test Framework
• Hybrid Test Framework

2. What is data driven framework

Data Driven Framework is one of the popular Automation Testing Framework in the current market. Data Driven automated testing is a method in which the test data set is created in the excel sheet, and is then imported into automation testing tools to feed to the software under test.

Selenium Webdriver is a great tool to automate web-based applications. But it does not support read and write operations on excel files

3. Where the test data will be stored in the FW?

4. Components of Framework

• Selenium IDE,
• Selenium RC,
• Selenium WebDriver,
• Selenium RC

5. How to count the links available in the form?

Use the below code for your reference:
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.concurrent.TimeUnit;
public class LinkCount {
   public static void main(String[] args) {
      System.setProperty("webdriver.chrome.driver", "C:\\Users\\ghs6kor\\Desktop\\Java\\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      String url = " https://www.credosystemz.com/";
      driver.get(url);
      driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS);
      //Using tagname with anchor
      List links = driver.findElements(By.tagName("a"));
      System.out.println(“The number of links is “ + links.size());
      driver.close();
   }
}

6. Different types of locators. Which locator is your preference and why?

• By CSS ID: find_element_by_id
• By CSS class name: find_element_by_class_name
• By name attribute: find_element_by_name
• By DOM structure or xpath: find_element_by_xpath
• By link text: find_element_by_link_text
• By partial link text: find_element_by_partial_link_text
• By HTML tag name: find_element_by_tag_name

7. Syntax of Xpath and cssSelector

		Syntax of Xpath
Xpath=//tagname[@attribute='value']
Syntax of cssSelector
node[attribute_name = ‘attribute_value’]

8. In what format you are giving your report to client

9. Conversion process of Testing report to XSLT

• Ant should be installed.
• We should have atleast some test case should be executed by TestNG Processor used in report

10. Processor used in report

		driver.switchTo().alert();
//Selenium-WebDriver Java Code for entering Username & Password as below:
driver.findElement(By.id("userID")).sendKeys("userName");
driver.findElement(By.id("password")).sendKeys("myPassword");
driver.switchTo().alert().accept();
driver.switchTo().defaultContent();

		

11. How to handle Authentication window?

System.setProperty("webdriver.chrome.driver","Path to the driver"); 
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
// Load the website
driver.get("http://www.naukri.com/");
// It will return the parent window name as a String
String parent=driver.getWindowHandle();
Sets=driver.getWindowHandles();
// Now iterate using Iterator
Iterator I1= s.iterator();
while(I1.hasNext())
{
String child_window=I1.next();
if(!parent.equals(child_window))
{
driver.switchTo().window(child_window);
System.out.println(driver.switchTo().window(child_window).getTitle());
driver.close();
}
}
//switch to the parent window
driver.switchTo().window(parent);

}
}

	

12. How to handle multiple window?

		package softwareTestingMaterial;
import org.testng.annotations.Test;
import java.util.Iterator;
import java.util.Set;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

	@Test
	public void testMultipleWindows() throws InterruptedException{
	System.setProperty("webdriver.gecko.driver", System.getProperty("user.dir")+"\\src\\test\\java\\drivers\\geckodriver.exe");
	// To open browser
	WebDriver driver=new FirefoxDriver();
	// To maximize browser
	driver.manage().window().maximize();
	// To open Naukri website with multiple windows
	driver.get("http://www.naukri.com/");
	// It will return the parent window name as a String
	String mainWindow=driver.getWindowHandle();
	// It returns no. of windows opened by WebDriver and will return Set of Strings
	Set set =driver.getWindowHandles();
	// Using Iterator to iterate with in windows
	Iterator itr= set.iterator();
	while(itr.hasNext()){
		String childWindow=itr.next();
	   	// Compare whether the main windows is not equal to child window. If not equal, we will close.
		if(!mainWindow.equals(childWindow)){
		driver.switchTo().window(childWindow);
		System.out.println(driver.switchTo().window(childWindow).getTitle());
		driver.close();
		}
	}
	// This is to switch to the main window

27. Why is Java platform/OS independent?

It allows its end users to access its source code on any other language automatically.

It’s a human readble language which makes it preferable from a bunch of people.

Its source code can be used to work on a different platform which makes it an independent platform to work on.

28. Have you used collections in your code?

Collection is the root of the collection hierarchy. A collection represents a group of objects known as its elements. The Java platform doesn’t provide any direct implementations of this interface.

29. What is the difference between Implicit and Explicit wait?

36. Write a program to check if you have received mail from hcl using webtable

37. Ur project architecture

38. Diff between hashmap and hashtable?

39. What is serialization?

Serialization in Java allows us to convert an Object to stream that we can send over the network or save it as file or store in DB for later usage.

Serialization in Java seems very easy to use at first but it comes with some trivial security and integrity issues

40. What is anonymous class?

Java anonymous class are like local class or inner class without a name. We can use java anonymous class to declare and instantiate a class at the same time.

41. How to create a immutable class?

	For example:
import java.util.HashMap;
import java.util.Map;
 
// An immutable class
public final class Student {
    private final String name;
    private final int regNo;
    private final Map metadata;
 
    public Student(String name, int regNo,
                   Map metadata)
    {
        this.name = name;
        this.regNo = regNo;
        Map tempMap = new HashMap<>();
        for (Map.Entry entry :
             metadata.entrySet()) {
            tempMap.put(entry.getKey(), entry.getValue());
        }
        this.metadata = tempMap;
    }
 
    public String getName() { return name; }
 
    public int getRegNo() { return regNo; }
 
    public Map getMetadata()
    {
        Map tempMap = new HashMap<>();
        for (Map.Entry entry :
             this.metadata.entrySet()) {
            tempMap.put(entry.getKey(), entry.getValue());
        }
        return tempMap;
    }
}
 
// Driver class
class Test {
    public static void main(String[] args)
    {
        Map map = new HashMap<>();
        map.put("1", "first");
        map.put("2", "second");
        Student s = new Student("ABC", 101, map);
        System.out.println(s.getName());
        System.out.println(s.getRegNo());
        System.out.println(s.getMetadata());
 
        // Uncommenting below line causes error
        // s.regNo = 102;
 
        map.put("3", "third");
        System.out.println(s.getMetadata()); // Remains unchanged due to deep copy in constructor
 
        s.getMetadata().put("4", "fourth");
        System.out.println(s.getMetadata()); // Remains unchanged due to deep copy in getter
    }
}
Output
ABC
101
{1=first, 2=second}
{1=first, 2=second}
{1=first, 2=second}
