D&B – Selenium Interview Questions

Here is the list of Selenium Interview Questions which are suitable for both Freshers and Experienced professionals. Our Selenium Trainers have answered all the below Questions.

Round 1-Written test:

How do you handle dynamic elements in Selenium WebDriver?

10+ questions from selelium drivers, xpath, cssSelector.

5+ questions from Java programming outputs like inheritance, looping outputs.

Round 2:

1. Tell me about yourself.

Answer according to your profile and experience.

2. About the framework, which currently using.

Answer according to your project.

3. Compare between Data driven & Keyword driven.

The important points to be note down between Data driven & Keyword driven are listed down below, In data driven testing, we can run our tests on multiple data in multiple combinations with the help of parameterization.

In keyword driven testing, the keywords that are developed represent an action.

The data driven framework revolves around the data.

In keyword driven testing, the entire team consisting of both automation and manual testers can both contribute for testing the product.

4. About Maven, Jenkins and ANT.

Maven:

It is a tool which is used for building and managing Java Based Projects. Basically to put it in simple words is a way to manage dependency for Java Based Project. Maven can be used when building project with POM (Page Object Model) when working on big projects.

Jenkins:

The leading open source automation server, Jenkins provides hundreds of plugins to support building, deploying and automating any project.

ANT:

Ant is a build tool for Java. Ant used for code compilation, deployment, execution process. Ant can be downloaded from Apache website.

5. TestNG annotations and clarify the each annotations.

TestNG is a testing framework created by Cédric Best and helps to cater a lot of our testing needs. It is widely used in Selenium. Annotations are taken from the Java language and are an excellent tool for the testers using TestNG.

6. What is current role in Test automation?

Selenium IDE is a firefox and chrome plugin to record and playback user interactions. Selenium WebDriver is used to create and execute test cases as a programming interface. Selenium Grid allows running tests on different machines and browsers in parallel.

Need to Switch your career to automation:

7. How do you rate yourself on Java?

driver.close() closes the current browser window whereas driver.quit() closes all the browser windows opened by the WebDriver. driver.close(); driver.quit();

8. Write a Java program ‘to read a statement from a file and tell the word count & char count?

import java.io.BufferedReader; import java.io.FileReader; public class CountWordFile { public static void main(String[] args) throws Exception { String line; int count = 0; //Opens a file in read mode FileReader file = new FileReader(data.txt); BufferedReader br = new BufferedReader(file); //Gets each line till end of file is reached while((line = br.readLine()) != null) { //Splits each line into words String words[] = line.split(); //Counts each word count = count + words.length; } System.out.println(Number of words present in given file: + count); br.close(); } }

9. Tell me about Grid and where and when you are using it?

Selenium Grid allows us to execute multiple instances of WebDriver or Selenium Remote Control tests in parallel which uses the same code base, hence the code need NOT be present on the system they execute. The selenium-server-standalone package includes Hub, WebDriver, and Selenium RC to execute the scripts in grid.

10. What are all the reports you are using?

To create effective reports, the following tools are used in selenium.

TestNG Reporting Tool
ReportNG
Allure
JUnit

11. Give the format of xml report. Do you have chart on your report?

Implicit Wait instructs WebDriver by setting a default wait time for the entire WebDriver instance. It applies to all elements before throwing an exception.

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

12. How do you maintain the selenium code [I said GIT]?

Keep Your Automation Designs Simple, Yet Strategic.
Establish Process For Keeping Automation Updated.
Inspire Developers For Keeping Testing In Mind.
Identify Flaky Tests And Work On Reducing Them.

13. Suppose two people are saving the code in GIT version controller, what would happen?

Input the file path directly to the file input element by using sendKeys() method.

WebElement uploadElement = driver.findElement(By.id(“upload”));

uploadElement.sendKeys(“/path/to/file”);

14. Which version of selenium are you currently using?

To handle alerts in Selenium WebDriver, use the Alert interface:

Switch to alert:

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

Accept the alert:

alert.accept();

Dismiss the alert:

alert.dismiss();

15. What are all the advanced features in it [2.44] compare to prior version?

Capture screenshot of specific web element.
Open the new tab on the browser.
Open a new window on the browser.
Chrome Dev tools.

16. Print Prime numbers using Java Program.

public class PrimeExample{ public static void main(String args[]){ int i,m=0,flag=0; int n=3;//it is the number to be checked m=n/2; if(n==0||n==1){ System.out.println(n+ is not prime number); }else{ for(i=2;i<=m;i++){ if(n%i==0){ System.out.println(n+" is not prime number"); flag=1; break; } } if(flag==0) { System.out.println(n+" is prime number"); } }//end of else } }

17. Read and write file from Excel, MS AccessDB and Text File.

In Selenium WebDriver, to take a screenshot use the TakesScreenshot interface.

File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

18. How do you run multiple suite and few more basic questions on Project experience?

Selenium WebDriver provides the Actions class to perform drag-and-drop operations.

Using dragAndDrop method:

WebElement source = driver.findElement(By.id(“source”));

WebElement target = driver.findElement(By.id(“target”));

Actions actions = new Actions(driver);

actions.dragAndDrop(source, target).build().perform();

19. Make yourself strong in Collections, File handling, Exception handling and JDBC from Java.

Selenium WebDriver provides three types of waits to handle synchronization issues:

Implicit Wait
Explicit wait
Fluent wait

20. Practice basic interview related programs of Java.

To perform advanced interactions, the operations available in Selenium WebDriver are clickAndHold, moveToElement, and release methods:

WebElement source = driver.findElement(By.id(“source”));

WebElement target = driver.findElement(By.id(“target”));

Actions actions = new Actions(driver);

actions.clickAndHold(source).moveToElement(target).release().build().perform();
