We'll examine the Top 25 Selenium Tricky
Interview Questions for Experienced in this blog.
These challenging Selenium interview questions
were carefully selected from the group of
questions thought to be most crucial for people
with advanced or experienced knowledge. Let's
look at these Selenium Tricky Interview Questions
without further ado.

• Tricky Interview Questions for Selenium
• 1. How do I debug tests in Selenium IDE?
• One of the traditional Selenium Tricky Interview
  Questions is this one.
• You must first put breakpoints where you wish to
  debug then step-by-step run the test after doing
  so.
• The test case is then executed.
• The execution then comes to a stop at the
  breakpoint's maintained location.
• Once this is complete, you can click the Run
  button to continue running each command in turn.

2. Why should TestNG be used with Selenium
RC? TestNG aids in delivering the crucial
flexibility required in particular circumstances.
For instance, we will be forced to run the test
cases from the command line if the automation
test suite's specification calls for it to
function with various client platforms and
servers. Additionally, it will be necessary to
add flexibility in the test-creation process and
to provide for the regular output of reports.
This is made possible by TestNG. Read our blog
post on "What are TestNG Annotations" if you want
to learn more about them.

• 3. How does Selenium WebDriver handle frames?
• The inline frame, often known as the iframe, is
  used to embed one HTML document inside of
  another.
• As a result, you have several choices.
• Choosing an iframe by ID
• "ID of the frame," driver.switchTo().frame
• Finding an iframe using tagName
• driver.switchTo().frame(driver.findElements(By.tag
  Name(iframe).get(0))
• iframe location using index
• frame(index)
• driver.switchTo().frame(0)
• "Name of the Frame" in frame
• "Name of the frame," driver.switchTo().frame
• frame (WebElement element)
• the Parent Window option
• driver.switchTo().defaultContent()

• 4. Take the following example Selenium Script
  works in Chrome but not in IE. How can you fix
  the problem?
• A script's ability to run on IE may be hindered
  for a variety of reasons. You can, however, make
  an effort to fix the problem in a variety of
  ways.
• Be sure to use the most recent version of the
  Selenium IE Driver.
• ensuring that the IE driver and the working
  environment are compatible
• Setting the 'Enabled Protected Mode' option on
  the Security Tab to the same value for each zone
• Continuing to configure the IE driver by
  importing dependencies and using the setProperty
  method
• minimising exceptions by using CSS selectors
• the creation of a registry entry
• While running the script, Internet Explorer's
  internet security settings ought to be disabled.
• utilising modern selenium jars
• when clicking items, using JavaScriptExecutor
  rather than native click
• enabling JavaScript support in the IE browser

5. Is it possible to test responsive web design
with Selenium? Applications are now used much
more frequently on smartphones and tablets as
well as laptops. Additionally, this has raised
the requirement for testing responsive web
design. However, it would be a very
time-consuming and laborious process to
personally test every programme across every
single platform. Additionally, it might cause
needless delays in the product's release.
Therefore, it makes sense to automate RWD
testing, and one may do so by using the Galen
framework. With its assistance, one may run tests
in the cloud and carry out parallel testing
because it operates in Selenium Grid.

• 6. What kinds of listeners are there in TestNG?
• TestNG's listener types include the following
• IConfigurable
• IExecutionListener
• IAnnotationTransformer
• IHookable
• IInvokedMethodListener
• IInvokedMethodListener2
• IConfigurationListener
• IReporter
• ITestListener
• IMethodInterceptor
• ISuiteListener

8
7. Which API is necessary for Selenium WebDriver
database testing? The Java Database Connectivity
(JDBC) API will be needed for this. It makes it
easier to run SQL statements.
9

• 8. Can Selenium handle window pop-ups?
• Selenium does not support handling of window
  pop-ups because it only supports testing online
  applications, not mobile or Windows-based ones.
  The handling of such pop-ups necessitates outside
  assistance. The external tools Autolt and Robot
  Class are two examples. An alert is displayed as
  a pop-up window with a warning message. There
  aren't many possibilities here.
• Dismiss the void ()
• When you select the "cancel" button in the alert
  box, this approach is activated.
• I accept void ()
• The "ok" button in the alert box calls this
  technique into action.
• text from a string ()
• This procedure is used to record the alert
  message.
• False sendKeys (String stringToSed)
• When you want to transmit some data to an alert
  box, you call this method.

• 9. Can Selenium WebDriver be used to take
  screenshots?
• Yes, as stated in the question above. The
  TakeScreenshot function can be used to take
  screenshots. In order to save the screenshot, you
  can use the getScreenshotAs() method.
• ((TakeScreenshot)driver) File scrFile
  (outputType. FILE) getScreenshotAs
•  
• 10. What Does a Robot Class Mean?
• The Robot class assists in giving the mouse and
  keyboard devices control. It contains
• KeyPress()
• when attempting to hit any key
• KeyRelease()
• invoked to cause the keyboard's pressed key to
  release
• MouseMove()
• used to command the mouse to move in the X and Y
  directions
• MousePress()
• asked to click the mouse's left button

11
11. What do Selenium assertions mean? What kinds
are there? The usage of assertions as checkpoints
aids in maintaining the orderly flow of commands.
They serve as validating tools that help
determine whether a test case is acting in
accordance with expectations or not. Some test
suites, like a sanity or a regression suite, run
for extended periods of time. It may not be
feasible to manually monitor the execution in
such circumstances. Testers use assertions to
designate test cases as passed or failed.
12

• There are primarily two categories of statements.
  Which are
• Softly imply
• Only the condition and the result are verified
  and provided by this statement. In the event that
  the test case fails, it does not lead to the
  termination of the test case execution.
• Firmly assert
• This assertion checks for the anticipated
  outcome, and if the condition is not met,
  execution is terminated and the
  "java.lang.AssertionError" exception is
  displayed.
• Selenium's various Hard Assertions come in the
  following varieties
• assertNull()
• assertNotNull()
• assertEquals()
• assertNotEquals()
• assertTrue()
• assertFalse()

13

• 12. How may broken links be located in Selenium?
• One of the frequently challenging Selenium
  interview questions is this one.
• You can keep going through the steps below to
  find broken links.
• Using the agt anchor tag, you must compile all of
  the links that are present on a web page. Use the
  attribute 'href' value to create a hyperlink for
  each of the agt tags.
• For each link, you must then issue HTTP queries
  and check the HTTP response code.
• You may detect whether the link is working or not
  based on the HTTP response code. After that, you
  can navigate to a URL using the driver.get()
  method, which should return a status of 200-OK.
  When the link returns a 200-OK, it is
  operational. However, if you receive a different
  status, that would mean the connection is broken.
• Repeat the procedure for every link that was
  captured.

13. How does Silk Test Tool work? Enterprise
applications can be tested for regression and
automated functionality using the Silk Test Tool.
It enables users to record application sessions
in order to construct tests. With the aid of the
programme, users may also improve the test by
including test logic and verifications as well as
replaying tests to guarantee the appropriate
operation of the apps.
14

• 14. What are the various navigation instructions
  that Selenium offers?
• The following commands are included on the list
• navigate().forward()
• Based on the user's browsing history, the command
  assists in directing them to the subsequent web
  page.
• navigate().back()
• According to the user's browser history, the
  command assists in directing the user to the most
  recent or previous web page.
• navigate().to()
• Based on the provided URL, the command assists in
  directing the user to a new web page in a new
  window.
• navigate().refresh()
• By reloading all of the web elements, the command
  assists the user in refreshing the currently open
  web page.

15

• 15. How does WebDriver assert the web page's
  title?
• You must take the subsequent actions in order to
  accomplish this goal.
• "import org.testng.Assert" is the command to
  import the Assert class.
• A WebDriver object must be created by you
  FirefoxDriver() new WebDriver driver
• This might be used to support the website's title.

16

• 16. How may a hybrid framework-based HTML report
  be created in TestNG?
• The following steps can be used to create a
  customised HTML report
• With the aid of an ant, Junit
• TestNG employs the built-in default file
• Use XSL files as well.
•  
• 17. In TestNG, how can I skip a method or a block
  of code?
• You can set the test annotation's 'enabled' value
  to false to bypass a certain test method.
• testing (enabled false)
• The enabled parameter's default value is true. As
  a result, it is not necessary to specify the
  annotation as true at the time of definition.

17
18. Describe the value of testing.xml The
importance of utilising TestNG in Selenium is
well known. However, how does TestNG define test
suites and test class groupings? Getting
instructions from the testing.xml file makes this
easier. The source code for testing cannot define
a test suite. As the suite is a crucial component
of execution, it is instead represented in an XML
file. You must generate a testing.xml file in
order to execute a set of test cases, or test
cases in a suite. The names of all the methods
and classes that you want to call as part of the
execution flow would be listed in
it. Additionally, the testing.xml file supports
parallel execution, group execution of test
cases, and execution of numerous test cases from
various classes.   19. What distinguishes the
commands driver.close() and driver.quit()? The
two commands are comparable in that neither takes
a value nor accepts any parameters.
18
20. What is the distinction between Selenium's
findElement() and findElements() functions?
findElement() findElements()  
The command helps in finding one particular element within the current page using the locating mechanism. It returns the first element located by the locator. The command helps in finding all the elements within the current page using the locating mechanism. Consequently, it returns a list of matching web elements found by the locator.
19

• 21. How many parameters are required by a
  Selenium command, at the very least?
• Selenium has four parameter choices. Which are
• Host
• Instead of a local host, Selenium can be
  connected to a specific IP address.
• Browser
• shows which browser should be used to run the
  selenium scripts.
• Specified Port
• The port number identifies the TCP/IP port that
  may be supplied to link the Selenium tests to the
  Grid hub. You should also confirm that no other
  programme with the same port number is running
  somewhere else on the same computer.
• URL
• The test cases within that are triggered by the
  application URL.
•  
• 22. How is the required functionality beneficial
  in the context of Selenium?
• This is yet another example of a challenging
  Selenium interview question.

20
Desired Capability describes a particular feature
or functionality. It has a number of key-value
pairs that can be used to record data about the
browser's name, its location in the system, its
version, and other things that affect how the
browser behaves when it is running. With
Selenium, the desired capability can be used to
configure the driver instance. It is especially
useful if you want to run the test cases on
several operating systems, browser versions, and
versions.   23. What is Page Factory? The Page
Object Model can be executed more efficiently
thanks to Page Factory. Object-oriented
implementation techniques are used. It functions
as a built-in POM framework that Selenium
WebDriver offers to enable Page Object Design
patterns. The By() method is used to implement
POM with Page Factory no imports or cache
storage are required. The components of the Page
Object are initialised using the Page Factory.
Use of "FindElements" is optional. An alternative
is to use annotations like _at_FindBy to locate Web
elements and the initElements method to
initialise web elements obtained from the Page
Factory class.
21
24. What purpose does database automation testing
serve? Is it possible to test databases with
Selenium? The importance of the database itself
can be used to determine the value of database
automation testing. The database is essential for
storing and organising data. Therefore, automated
database testing aids in
22

• precise value storing and retrieval from the
  database
• Processing data without errors
• Finding issues that front-end testing cannot pick
  up
• ACID property validation (ACID implies Atomicity,
  Consistency, Isolation and Durability)
• Data Integrity and Proper Data Mapping
• Database testing can absolutely be done with
  Selenium. A connection between the database and
  the server will need to be made. A JDBC
  connection can make this easier. JDBC, a Java API
  with a SQL foundation, aids with database
  connection and query execution. You can then
  process the outcomes. The following are the main
  parts of JDBC
• Driver Supervisor
• Driver
• Connection
•  
• 25. What does TestNG's parameterization mean?
• In essence, parameterization is a technique that
  involves declaring values and passing them as
  test class parameters. Developers benefit from
  repeatedly running the same test with different
  values. When several login credentials for
  various test environments are needed, it is
  helpful. With Data Providers and testng.xml,
  TestNG makes it easier to give arguments to the
  test methods.
