Points to remember for selenium interview

Few points to remember about selenium when you are going for selenium interview. As interviewer may wants to check your knowledge on these things too.

1. Selenium Projects : selenium interviewer may wants to know your knowledge on different selenium projects. Selenium is not a single project. There are multiple selenium projects like Selenium IDE, Selenium RC(Remote Control), Selenium WebDriver and Selenium Grid. All these projects are developed for web application’s testing purpose.

2. Selenium IDE is Limited version : Selenium IDE(Firefox Add-on) is record and playback tool. You can automate simple web application scenarios(Example : Form submission, Navigation, etc..) using selenium IDE. But if you wants to automate complex scenarios then it will be hard to automate it using selenium IDE. In this case, You can use selenium RC or selenium webdriver.

3. Selenium Open-source : All the selenium projects are open-source so you can use any of them in free as per your requirement.

4. No built-in IDE : Commercial automation tools like QTP and TestComplete have it’s own IDE(Integrated development Environment) to write automation test scripts. But selenium do not have it’s own IDE. So it relies on other IDEs like Eclipse(Java), Visual Studio(C#), etc.

5. Be master in programming : To be good tester in selenium and work with giant companies, You must have strong knowledge of any one programming language. You can choose language as  per your interest. So i am suggesting you to be master in your selected language before learning selenium. Interviewer will ask you 60% programming language questions and 40% selenium interview questions.

6. What is test automation in software testing : Selenium interviewer may ask you this question. In software testing, Test automation is process of testing software application automatically using special software. It will control test cases execution it self, compare expected and actual test results and provide test result reports.

7. What are the benefits of test automation? : 

Save time and money : Automation testing will save time and money as we need to create test automation scripts just once and then we can run it whenever required. Automation test scripts will run itself so required very less human efforts compared to manual testing. Also you can test your application in different browsers using same test script so it will decrease your rework.

Improve testing accuracy : Sometimes human can make mistake but machine can’t. Once you record script in correct way, tool will run it every time as expected so it will improve your testing accuracy.

Test Coverage : As your all test cases are scripted so all the test cases will be executed in each test cycle on all browsers. So it will improve your test coverage.

8. Why selenium as automation tool?

It is Open-source testing tool.

Able to operate it on almost all OS.

Selenium support multiple languages to create test scripts so you can choose your preferred language.

Selenium support multiple browsers.

Good online support.

Selenium allow us to integrate other open-source unit testing frameworks like TestNG, JUnit, NUnit.

Using selenium Grid, We can run automation tests simultaneously on different machines, OS and browsers.

Able to create frameworks as per your requirement like Keyword Driven, Data driven and Hybrid etc.

We can integrate selenium with maven. Maven is helpful to compile source code, set dependencies so that it will download required files automatically.

Also we can integrate Jenkins or Hudson with selenium for continuous integration.

We can use selenium to test web applications in mobile too.

It is not only testing tool but if you have repetitive web-based tasks then you can use selenium to perform those tasks automatically.

WebDriver Automation Testing Interview Questions And Answers- Part 2

6 : What are the benefits of automation testing.

Answer : We can get bellow given benefits If automate our software testing process.

Fast Test Execution : Manual software testing process Is time consuming. Automation tests are faster and takes less time to execute tests compared to manual test execution.

Re-usability Of Test Cases : You need to prepare automation test cases only one time. Then you can use same test cases for all upcoming version release of software application. However you need to modify your test cases If there Is any flow change of business logic changes In software. But It Is less time consuming.

Testing Cost Reduction : You have to put human efforts only one time to automate your software test process. Latter on automation tool will work for you at place of human resource.

Better Test Coverage In Each Version Release: You have to Implement test scenarios only once In your automation test cases. Latter on you can execute same test cases In all upcoming release. So each scenarios will be tested In every version release.

Easy For Compatibility Testing : It Is easy to run same tests In combination of different OS and browser environments using automation tools.

7 : Does Selenium WebDriver Support Record And Playback Facility?

Answer : No. WebDriver do not have any record and playback facility. But you can record your tests In one of the selenium version called Selenium IDE and then you can export your recorded tests In webdriver compatible format as per your preferred language.

8 : Which Operating systems support Selenium WebDriver?
Answer : At present, Mainly bellow given operating systems support Selenium WebDriver.

Windows – Windows XP, Windows 7, Windows 8 and Windows 8.1

Apple OS X

Linux – Ubuntu. Other versions of linux should support too.

9 : Selenium WebDriver Is Paid Or Open Source Tool? Why you prefer to use It? 

Answer : All versions of selenium software testing tool are open source. You can use any version of selenium In free of charge.

I choose to use It because

Open Source.

It has multi-browser support.

Multi-OS support.

Multi types of locators support. So If one not works, We can use another type.

Web as well mobile application testing support.

Many testers are using selenium WebDriver to automate their testing process. So getting solution of any complex Issue very easily on Internet.

It Is extendable and flexible.

Continues support from WebDriver’s development team to Improve the API and resolve current Issues.

WebDriver driver = new FirefoxDriver();

12 : What Is XPath and what Is use of It In WebDriver?

Answer : In Selenium WebDriver software testing tool, XPath is used to locate the elements. Using XPath, We can navigate through elements and attributes In an XML document to locate software webpage elements like buttons, text box, links, Images etc..

13 : Which tool you are using to find the XPath of any element?

Answer : I am using Mozilla Firefox AddOns FireBug and FirePath to find the XPath of software web elements.

14 : What is the difference between absolute XPath and relative XPath?

Answer :

Absolute XPath : Absolute XPath Is the full path starting from root node and ends with desired descendant element’s node. It will start using single forward slash(/) as bellow.

Example Of Absolute XPath : 


Relative XPath : Instead of starting from root node, Relative XPath starts from any In between node or current element’s node(last node of element). It will start using double forward slash(//) as bellow.
Example Of Relative XPath : 


15 : How To Handle Dynamic Changing IDs In XPath. 
Example : //div[@id=’post-body-3647323225296998740′]/div[1]/form[1]/input[1]
In this XPath “3647323225296998740” Is changing every time when reloading the page. How to handle this situation?

Answer : There are many different alternatives In such case.

Alternative 1 : Look for any other attribute which Is not changing every time In that div node like name, class etc. So If this div node has class attribute then we can write xpath as bellow.

//div[@class=’post-body entry-content’]/div[1]/form[1]/input[1]

Alternative 2 : You can use absolute xpath(full xpath) where you not need to give any attribute names In xpath.


Alternative 3 : Use starts-with function. In this xpath’s ID attribute, “post-body-” part remain same every time. So you can use xpath as bellow.


Alternative 4 : Use contains function. Same way you can use contains function as bellow.

17 : How many types of waits available In selenium WebDriver

Answer : There are two types of waits available In selenium WebDriver software automation testing tool.

Implicit Wait

Explicit Wait

18 : What Is Implicit Wait In Selenium WebDriver?

Answer : Sometimes, Elements are taking time to be appear on software web application page. Using Implicit wait In webdriver software testing test case, We can poll the DOM for certain amount of time when some element or elements are not available Immediately on webpage.

Implicit Wait Example :

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

If you will write above syntax In your test, Your WebDriver test will wait 10 seconds for appearing element on page.

19 : What Is Explicit Wait In Selenium WebDriver?

Answer : Using explicit wait code In selenium webdriver software automation testing tool, You can define to wait for a certain condition to occur before proceeding further test code execution.

Explicit Wait Example :

WebDriverWait wait = new WebDriverWait(driver, 20);


Above code will wait for 20 seconds for targeted element to be displayed and enabled or we can say clickable.

20 : I wants to pause my test execution for fix 10 seconds at specific point. How can I do It?

Answer : You can use java.lang.Thread.sleep(long milliseconds) method to pause the software test execution for specific time. If you wants to pause your test execution for 10 seconds then you can use bellow given syntax In your test.


Selenium WebDriver Job Interview Questions Part – 5

21 : How does selenium RC software testing tool drive the browser? 

Answer :
When browser loaded In Selenium RC, It ‘injected’ javascript functions into the browser and then It Is using javascript to drive the browser for software application under test.

22 : How does the selenium WebDriver drive the browser?

Answer : Selenium webdriver software testing tool works like real user Interacting with software web page and Its elements. It Is using each browser’s native support to make direct calls with browser for your software application under test. There Is not any Intermediate thing In selenium webdriver to Interact with web browsers.

23 : Do you need Selenium Server to run your tests In selenium WebDriver?

Answer : It depends. If you are using only selenium webdriver API to run your tests and you are running your all your tests on same machine then you do not need selenium server because In this case, webdriver can directly Interact with browser using browser’s native support.

You need selenium server with webdriver when you have to perform bellow given operations with selenium webdriver.

When you are using remote or virtual machine to run webdriver tests for software web application and that machine have specific browser version that is not on your current machine.

When you are using selenium-grid to distribute your webdriver’s test execution on different remote or virtual machines.

24 : Bellow given syntax will work to navigate to specified URL In WebDriver? Why? driver.get(“”);

Answer : No. It will not work and show you an exception like : “Exception in thread “main” org.openqa.selenium.WebDriverException: f.QueryInterface is not a function” when you run your test.

You need to provide http:// protocol with URL In driver.get method as bellow.


Now It will work.

25 : Tell me a reason behind bellow given WebDriver exception and how will you resolve It?

“Exception in thread “main” org.openqa.selenium.NoSuchElementException: Unable to locate element”

Answer : You will get this exception when WebDriver Is not able to locate element on the page of software web application using whatever locator you have used In your test. To resolved this Issue, I will check bellow given things.

First of all I will check that I have placed Implicit wait code In my test or not. If you have not placed Implicit timeout In your test and any element Is taking some time to appear on page then you can get this exception. So I will add bellow given line at beginning of my test case code to wait for 15 seconds for element to be present on page. In 70% cases, this step will resolved Issue. 

 driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);

Another reason behind this Issue Is element’s ID Is generated dynamically every time when reloading the page. If I have used element’s ID as an element locator or used It In xpath to locate the element then I need to verify that ID of element remains same every time or It Is changing? If It Is changing every time then I have to use alternative element locating method. In 20% cases, This step will resolve your Issue.

If Implicit wait Is already added and element locator Is fine then you need to verify that how much time It(element) Is taking to appear on page. If It Is taking more than 15 seconds then you have to put explicit wait condition with 20 or more seconds wait period as bellow. In 5 to 10% cases, This step will resolve your Issue. 

 WebDriverWait wait = new WebDriverWait(driver, 25);

Selenium Questions Part – 8

36 : When I am running software web application’s tests In Firefox Browser using selenium webdriver, It Is not showing me any bookmarks, addons, saved passwords etc. In that browser. Do you know why?

Answer : Yes. It Is because all those bookmarks, addons, passwords etc.. are saved In your regular browser’s profile folder so when you launch browser manually, It will use existing profile settings so

It will show you all those stuffs. But when you run your software web application’s tests In selenium webdriver, It Is opening new browser Instance with blank/new profile. So It will not show you bookmarks and all those things In that browser Instance.

You can create custom firefox profile and then you can use It In selenium webdriver test. In your custom profile, you can set all required bookmarks, addons etc

37 : Arrange bellow given drivers In fastest to slowest sequence?

Firefox Driver, HtmlUnit Driver, Internet Explorer Driver.

Answer : HTMLUnit Driver Is faster than all other drivers because It Is not using any UI to execute test cases of software web application. Internet Explorer driver Is slower than Firefox and HtmlUnit driver. So, Fastest to slowest driver sequence Is as bellow.

HtmlUnit Driver

Firefox Driver

Internet Explorer Driver

38 : What Is Ajax?

Answer : Asynchronous JavaScript and XML Is full form of AJAX which Is used for creating dynamic web pages very fast for software web applications. Using ajax, We can update page behind the scene by exchanging small amounts of data with server asynchronously. That means, Using ajax we can update page data Without reloading page.

39 : How to handle Ajax In selenium WebDriver?

Answer : Generally we are using Implicit wait In selenium WebDriver software automation tests to wait for some element to be present on page. But Ajax call can not be handled using only Implicit wait In your test because page not get reloaded when ajax call sent and received from server and we can not assume how much time It will take to receive ajax call from server.

To handle ajax call In selenium WebDriver software automation tests, We needs to use webdriver’s FluentWait method or Explicit Waits which can wait for specific amount of time with specific condition.

40 : On Google search page, I wants to search for some words without clicking on Google Search button. Is It possible In WebDriver? How?

Answer : Yes we can do It using WebDriver sendKeys method where we do not need to use Google Search button. Syntax Is as bellow.

driver.findElement(By.xpath(“//input[@id=’gbqfq’]”)).sendKeys(“Search Syntax”,Keys.ENTER);

In above syntax, //input[@id=’gbqfq’] Is xPath of Google search text field. First It will enter “Search Syntax” text In text box and then It will press Enter key on same text box to search for words on Google.

41 : What kind of software testings are possible using selenium WebDriver? We can use It for any other purpose except testing activity?

Answer : Generally we are using selenium WebDriver for functional and regression testing of software web applications.

42 : Give me any five different xPath syntax to locate bellow given Input element.

<input id=”fk-top-search-box” class=”search-bar-text fk-font-13 ac_input” type=”text” autofocus=”autofocus” value=”” name=”q” />

Answer : Five xPath syntax for above element of software web application page are as bellow.



//input[starts-with(@class, “search-bar-text”)]

//input[@id=’fk-top-search-box’ or @name=’q’]

//input[starts-with(@id, ‘fk-top-search-box’) and contains(@class,’fk-font-13′)]

43 : Can you tell me two drawbacks of xPath locators as compared to cssSelector locator?

Answer : Two main disadvantage of xPath locator as compared to cssSelector locator are as bellow.

It Is slower than cssSelector locator.

xPath which works In one browser may not work In other browser for same page of software web application because some browsers (Ex. IE) reads only Lower-cased tag name and Attribute Name. So If used It In upper case then It will work In Firefox browser but will not work In IE browser. Every browser reads xPath In different way. In sort, do not use xPath locators In your test cases of software web application If you have to perform cross browser testing using selenium WebDriver software testing tool.

44 : Why xPath locator Is much more popular than all other locator types In WebDriver?

Answer : xPath locators are so much popular In selenium webdriver test case development because

It Is very easy to learn and understand for any new user.

There are many functions to build xPath In different ways like contains, starts-with etc.. So If one Is not possible you will have always another option to build xPath of any element.

Presently many tools and add-ons are available to find xpath of any element.

45 : Give me WebDriver’s API name using which we can perform drag and drop operation.

Answer : That API’s name Is Advanced User Interactions API using which we can perform drag and drop operation on page of software web application. Same API can help us to perform some other operations too like moveToElement, doubleClick, clickAndHold, moveToElement, etc

Interview Questions For Selenium WebDriver Part 10

46 : Can we perform drag and drop operation In Selenium WebDriver? Tell me a syntax to drag X element and drop It On Y element.
Answer : Yes, We can perform drag and drop operation using selenium webdriver software testing tool’s Advanced User Interactions API. Syntax Is like below.

new Actions(driver).dragAndDrop(X, Y).build().perform();

47 : Do you have faced any technical challenges with Selenium WebDriver software test automation?

Answer : Yes, I have faced below given technical challenges during selenium webdriver test cases development and running for software web application.

Sometimes (Not always), Some elements like text box, buttons etc. are taking more time(more than given Implicit wait time) to appear on page of software web application or to get enabled on page. In such situation, If I have used only Implicit wait then my test case can run fine on first run but It may fail to find element on second run. So we need provide special treatment for such elements so that webdriver script wait for element to be present or get enabled on page of software web application during test execution. We can use Explicit wait to handle this situation.

Handling dynamic changing ID to locate element Is tricky. If element’s ID Is changing every time when you reload the software web application page and you have to use that ID In XPath to locate element then you have to use functions like starts-with(@id,’post-body-‘) or contains(@id,’post-body-‘) In XPath..

Clicking on sub menus which are getting rendered on mouse hover of main menu Is some what tricky. You need to use webdriver’s Actions class to perform mouse hover operation.

If you have to execute your test cases In multiple browsers then one test case can run successfully In Firefox browser but same test case may fail In IE browser due to the timing related Issues (nosuchelement exception) because test execution In Firefox browser Is faster than IE browser. You can resolve this Issue by Increasing Implicit wait time when you run your test In IE browser.

Above Issue can arise due to the unsupported XPath In IE browser. In this case, You need to (ID, Name, CSSSelector etc.) locate element.

Handling JQuery elements like moving pricing slider, date picker, drag and drop etc.. Is tricky. You should have knowledge of webdriver’s Advanced User Interactions API to perform all these actions.

Working with multiple Windows, Frames, and some tasks like Extracting data from web table, Extracting data from dynamic web table, Extracting all Links from page, Extracting all text box from page are also tricky and time consuming during test case preparation.

There Is not any direct command to upload or download files from web page using selenium webdriver. For downloading files usign selenium webdriver, You need to create and set Firefox browser profile with webdriver test case.

Webdriver do not have any built In object repository facility. You can do It using java .

Webdriver do not have any built In framework or facility using which we can achieve below given tasks directly : 1. Capturing screenshots, 2. generating test execution log, 3. reading data from files, 4. Generating test result reports, Manage test case execution sequence. To achieve all these tasks, We have to use external services with webdriver like Log4J to generate log, Apache POI API to read data from excel files, Testng XSLT reports to generate test result reports. TestNG to manage test case execution, .properties file to create object repository. All these tasks are very time consuming.I have described how to create data driven framework step by step for selenium webdriver. That framework contains all above functionality.

You can share other webdriver technical challenges which you have faced by commenting below so that your experience can help to others too.
