Top 15 Selenium Interview Questions and Answers for 2022
Selenium is an open-source automated testing tool that enables
you to test web applications on many browsers. It was first used when manual
testing started to provide several challenges, and there was a great need for
an automated testing approach. The majority of the Selenium Interview Questions are collated in this Selenium
interview questions blog. Let us better understand the concept of
"Selenium Locators" in depth by covering the details and preparing
ourselves with Selenium Basic Interview
Questions.

What is Selenium?
Selenium is an automated testing framework that is open-source
(free) and used to verify web applications on various browsers and operating systems.
A wide range of languages, not limited to Java, C#, Python, etc., can be used
to create Selenium Test Scripts. Simply put, testing executed with the help of
the Selenium testing tool is known as Selenium Testing.
What is the difference
between Selenium 2.0 and Selenium 3.0?
To create Selenium 2.0, the Original Selenium and Web Driver
projects were combined. As a result, selenium 2.0 is a helpful tool for
automated web application tests. This results from a merger between the
Selenium project and the WebDriver project. Because of the merge, support for
Selenium RC has been deprecated, but it is still in use for compatibility with
older versions of the framework.
The newer Selenium 3.0 is a more robust update to the previous
version. It doesn't require Selenium RC and has built-in compatibility with
older systems. In addition, several improvements and bug fixes were included in
the latest release.
What are the various
Components of Selenium Suite?
The term "Selenium Suite" refers to the collection of
testing tools that make up Selenium rather than the individual products that
make up Selenium. Each of these resources is designed for use in particular
kinds of testing situations. The following are its four main parts:
●
Selenium Integrated Development Environment (IDE): It's a
recorder and player that may be downloaded as a Firefox extension. It is
developed to speed up the production of automation scripts.
●
Selenium Remote Control (RC): The Selenium Remote Control server
allows users to write Test cases in any language they like. The commands
provided in the test scripts are accepted by the server and transmitted to the
browsers.
●
Selenium Grid: The Selenium Grid coordinates the simultaneous
distribution of commands to multiple devices. It allows the test cases to be
run simultaneously across multiple browsers and environments. It provides
concurrency and integrity in the Test Suite Execution.
●
Selenium Web driver: Selenium Web Driver is a programming
interface to generate and test cases. It allows you to perform operations on
various HTML components. Unlike Selenium Remote Control, this Web driver does
not necessitate a third-party server.
What are the limitations of
Selenium testing?
The limitations of Selenium testing are:
●
Absence of reliable tech support: Due to Selenium's status as an
open-source technology, it does not have a team of experts to answer questions
from users. Only web-based software is tested. If you want to test desktop and
mobile applications using Selenium, you'll need to combine it with other tools
like Appium and TestNG.
●
Requires Knowledge of Programming Languages: Users of Selenium
WebDriver should have a rudimentary understanding of programming.
●
Restricted support for image testing: Selenium does not have a
reporting and test management capability built in; hence it must be connected
with other tools, such as TestNG or JUnit.
What are the testing types
that can be supported by Selenium?
The different testing types are:
Selenium supports Regression testing and Functional testing.
- Regression testing: The term
"regression testing" refers to running some or all of the test
cases that have already been completed to verify the continued operation
of the system's current features. Here are the steps to take:
●
It's a re-test; therefore, they run all of the tests from the
original test suite again. It ends up costing a lot of money and taking a lot
of time.
●
When doing a regression analysis, choose between feature tests,
integration tests, and end-to-end tests.
●
Test cases are prioritized by considering their business's
importance and test features.
- Functional Testing: Verifying that the
application's features all work as intended is a part of functional
testing. The steps involved are:
●
Determine the input being used in the test
●
Results from test computation
●
Play the test
●
Analyze the difference between the expected result and the
actual result.
List the different Selenium
tools.
The different Selenium tools are:
●
Selenium Integrated Development Environment (IDE)
●
Selenium Remote Control (RC)
●
Selenium Web Driver.
●
Selenium Grid.
What is the difference
between Assert and Verify commands?
Assert:
●
We can perform a presence check to determine if anything is
present on the page.
●
When an inspection fails, the test immediately stops. That's
where the code simply stops doing what it is supposed to.
Verify:
●
Its sole purpose is to denote the truth or falsity of the
specified condition.
●
Because of this, the program's flow of control does not cease.
In general, unlike the Assert statement, which does halt the
execution, the Verify statement continues processing.
List the different types of
locators in Selenium.
The different types of locators in Selenium are:
●
By CSS ID: find_element_by_id
●
By CSS class name: find_element_by_class_name
●
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
●
By name attribute: find_element_by_name
●
By DOM structure or xpath: find_element_by_xpath
List the different types of
Drivers in WebDriver.
The different types of drivers in WebDriver are:
●
Chrome Driver
●
Chromium Driver
●
Edge Driver
●
Safari Driver
●
EventFiring WebDriver
●
Remote WebDriver
●
Firefox Driver
●
Internet Explorer Driver
●
OperaDriver
What is Selenese? How is it
classified?
Selenium instructions used to test your web app are known as
"Selenese." With Selenese, a tester can check for things like broken
links, the presence of a UI object, Ajax functionality, notifications, windows,
and list options. The classification are:
●
Action: An Action is a command that directly affects the
software.
●
Accessors: User-defined variables typically have accessors that
let the user save specific values.
●
Assertions: Compares the actual state of the program with a
predetermined standard.
What are the types of waits
supported by WebDriver?
The types of waits supported by WebDriver are:
Implicit wait: These waits are utilized
throughout the entire test script to offer a default waiting period (let's say
30 seconds) between the succeeding test stages. As a result, the next test step
would not be performed until 30 seconds had passed since the last test step was
completed.
Explicit wait: These waits stop execution
until a specific requirement is met or the allotted amount of time has passed.
While implicit waits are not constructed for any specific instance, explicit
waits are.
What is meant by an exception
test in Selenium?
A test class is designed to throw an exception is said to be an
exception test. Therefore, there must be a @Test annotation with the name of
the expected exception enclosed in brackets.
