Top Selenium Interview Questions And Answers. We are all aware of the growing impact of internet and web applications in today’s world. Almost every aspect of our life is governed by the internet. So much so that, most businesses rely heavily on the internet for interacting with their customers. When there is so much dependency on the web application, then they should be reliable and behave exactly as expected right? So, how can you ensure reliability? By testingthe web applications. This brings up the next question, how frequently will you be testing them? Doing it manually is time consuming, tedious, boring, prone to errors and so on. The solution to manual testing is automation testing.
In this chapter, you’ll learn how to test your Joomla site using three important open source tools.
By now, you can guess why automation testing professionals are so much in demand, and Selenium being one of the best automation testing tool for web apps, is used by almost every company and these companies don’t seem to stop hiring for testing job roles. This is what has prompted me to write this blog on the 3.

Selenium interview questions. Benefits Of Automation Testing. But you might ask, why only Selenium and not any other tool? That is because Selenium is open source and it’s easy adoption has earned itself the tag of being the poster boy of web testing tools. With a whopping 3.
IT world for professionals from various domains. So, read the entire list of Selenium interview questions and answers covered in this blog and prepare yourself for a job interview of a Selenium tester. Let’s get started! Top 3. 5 Selenium Interview Questions And Answers. The entire set of Selenium interview questions, is divided into three sections: Basic level. Advanced level. Test.
NG framework for Selenium. A. Basic Level – Selenium Interview Questions. What are the advantages and disadvantages of Selenium over other testing tools like QTP and RFT? The advantages of Selenium over QTP and RFT are: License: Selenium is open source, whereas HP’s QTP and IBM’s RFT are licensed software. Environment Support: Selenium supports Windows OS, Linux OS, Solaris OS X (If browser & JVM or Java. Script support exists), whereas QTP and RFT work only on Windows OS.
Programming Language Support: Selenium supports Java, C#, Ruby, Python, Perl, PHP and Java. Script, whereas RFT supports only Java and C# and QTP supports only VBScript. Hardware resource consumption during script execution: Selenium consumes very less hardware resource, but QTP and RFT a lot of hardware resource. Coding experience: For Selenium, coding skills should be very good along with technical capabilities of integrating the framework, whereas coding experience and skills are not that much needed for QTP and RFT.
What are the significant changes in upgrades in various Selenium versions? Selenium v. 1 included only three suite of tools: Selenium IDE, Selenium RC and Selenium Grid.
Note that there was no Web. Driver in Selenium v. Selenium Web. Driver was introduced in Selenium v. With the onset of Web. Driver, Selenium RC got deprecated and is not in use since. Older versions of RC is available in the market though, but support for RC is not available.
Currently, Selenium v. IDE, Web. Driver and Grid. IDE is used for recording and playback of tests, Web. Driver is used for testing dynamic web applications via a programming interface and Grid is used for deploying tests in remote host machines. Explain the different exceptions in Selenium Web.
Driver. Exceptions in Selenium are similar to exceptions in other programming languages.The most common exceptions in Selenium are: Timeout.Exception: This exception is thrown when a command performing an operation does not complete in the stipulated time. How To Remove Windows Os And Install Ubuntu To Usb . No. Such. Element.Exception: This exception is thrown when an element with given attributes is not found on the web page.Element. Not. Visible.Exception: This exception is thrown when the element is present in DOM (Document Object Model), but not visible on the web page.
Stale. Element. Exception: This exception is thrown when the element is either deleted or no longer attached to the DOM. What is exception test in Selenium? An exception test is an exception that you expect will be thrown inside a test class.
If you have written a test case in such way that it should throw an exception, then you can use the @Test annotation and specify which exception you will be expecting by mentioning it in the parameters. Take a look at the example below: @Test(expected. Exception = No. Such. Element. Exception. Do note the syntax, where the exception is suffixed with . Why and how will you use an Excel Sheet in your project? The reason we use Excel sheets is because it can be used as data source for tests.
An excel sheet can also be used to store the data set while performing Data. Driven Testing. These are the two main reasons for using Excel sheets. When you use the excel sheet as data source, you can store the following: Application URL for all environments: You can specify the URL of the environment in which you want to do the testing like: development environment or testing environment or QA environment or staging environment or production/ pre- production environment. User name and password credentials of different environments: You can store the access credentials of the different applications/ environments in the excel sheet. You can store them in encoded format and whenever you want to use them, you can decode them instead of leaving it plain and unprotected. Test cases to be executed: You can list down the entire set of test cases in a column and in the next column, you can specify either Yes or No which indicates if you want that particular test case to be executed or ignored.
When you use the excel sheet for Data. Driven Test, you can store the data for different iterations to be performed in the tests. For example while testing a web page, the different sets of input data that needs to be passed to the test box can be stored in the excel sheet. How can you redirect browsing from a browser through some proxy? Selenium provides a PROXY class to redirect browsing from a proxy.
Look at the example below: String PROXY = “1. Proxy proxy = new. Proxy(). proxy. set. HTTPProxy(Proxy). Ftp. Proxy(Proxy). Ssl. Proxy(Proxy). Desired. Capabilities cap = new Desired.
Capabilities(). cap. Capability(Capability. Type. PROXY, proxy). Web. Driver driver = new Firefox. Driver(cap). 7. What is POM (Page Object Model)? What are its advantages?
Page Object Model is a design pattern for creating an Object Repository for web UI elements. Each web page in the application is required to have it’s own corresponding page class. The page class is thus responsible for finding the Web.
Elements in that page and then perform operations on those Web. Elements. The advantages of using POM are: Allows us to separate operations and flows in the UI from Verification – improves code readability. Since the Object Repository is independent of Test Cases, multiple tests can use the same Object Repository. Reusability of code.
What is Page Factory? Page Factory gives an optimized way to implement Page Object Model. When we say it is optimized, it refers to the fact that the memory utilization is very good and also the implementation is done in an object oriented manner. Page Factory is used to initialize the elements of the Page Object or instantiate the Page Objects itself.
Annotations for elements can also be created (and recommended) as the describing properties may not always be descriptive enough to differentiate one object from the other. The concept of separating the Page Object Repository and Test Methods is followed here also. Instead of having to use ‘Find. Elements’, we use annotations like: @Find. By to find Web. Element, and init. Elements method to initialize web elements from the Page Factory class.@Find. By can accept tag.
Name, partial. Link. Text, name, link.
Text, id, css, class. Name & xpath as attributes. What are the different types of WAIT statements in Selenium Web. Driver? Or the question can be framed like this: How do you achieve synchronization in Web. Driver? There are basically two types of wait statements: Implicit Wait and Explicit Wait.
Implicit wait instructs the Web. Driver to wait for some time by polling the DOM. Once you have declared implicit wait, it will be available for the entire life of the Web. Driver instance. By default, the value will be 0. If you set a longer default, then the behavior will poll the DOM on a periodic basis depending on the browser/ driver implementation.
