Abstract - Testing in Software developmentprocessisthe
most costly and tedious process for QA Testers. As the need
of Web applications are growing testing has to grow
tremendously to test GUI of these web application hence the
automation becomes challenging because of its dynamically
changing nature. Numerous automation testing has been
done since decade yet they result into halfway automated or
need more tester inclusion. Hence tool for testing needs to
be invented which has the ability to enhance the testing
performance and its competences as well. In this paper we
will discuss the new automation testing tool Selenium web
driver. Selenium web driver is open source software
available for different windows and different web browser.
Key Words: Automation Testing, Manual Testing,
Selenium Web Driver
1. INTRODUCTION
Software testing is a procedure of executing a program or
application with the purpose of finding the productbugs.It’s
the process of validating and verifying all the components of
a system and also checking it satisfies specified
requirements and achieving the expected quality [1].
Manual testing is the process of manually testing software
for finding bugs this testing is performed without using any
testing tool it requires a tester to play the role of an end user
and verifies all the correct behaviorofsoftwarecomponents.
But this testing is not effective for large projects as it
requires more resources and time [1].
Automated testing is a process in which tool is used to
execute the pre-defined scripts and finding the defects.
Automation testing improves the accuracy, saves the tester
time and resources. It is suitable for large projects and best
in the repeatedly changingenvironmentwherehugeamount
of regression testing is required to be performed it also
increases the effectiveness and efficiency of softwaretesting
[1].
In this paper we have discussed one of the intelligent
automated testing tool Selenium Web Driver is the object
oriented API and newest addition to the selenium toolkit
This tool provides all kind of phenomenal features and
helped to overcome all the limitations of the old
implementation.
Two common methodologies for test automation:
Code-Driven testing.
The interfaces to classes, modules or libraries are tested
with multiple and variety of input argumentstovalidatethat
the results that are returned are precise [2].
Graphical User Interface testing (GUI).
A testing system that creates UI events, for example,
keystrokes and mouse clicks and sees the varieties that
outcome in the UI, to approve that the recognizable conduct
of the program is exact [2].
1.1 Test Automation
Test automation is the use of special software which
automates the repetitive and necessarytask andcontrolsthe
execution of tests comparingactual resultswiththeexpected
results or perform additional testing that would be difficult
to do manually. Many test automation tools give record and
playback features enabling clients to intelligently record
activities and replay them back to many times advantage of
this tool is that it needs no coding or improvement of the
software. However this methodology has several
disadvantages as tests need to be re-recorded evenforsmall
changes in the applicationlikemoving thecontrolsrenaming
the controls. Record and playback also frequently adds
indecorous activities or erroneously records some activities
[2].
There are many advantages of test automation with respect
to execution time, speed of test execution, repeatability of
the tests, less human intervention. There are a number of
feasible and open source tools available for test automation
and selenium is one of the most widely used open source
tool [2].
Test automation has many advantages some of these are:
• Repeated regression testing
• Quick feedback to the developers

• Indefinite repetitions of test case execution
• Support for the development methodologies
• Agile and extreme development
• Orderly documentation of test cases
• Customized reporting of the defects
• Finding defects missed during manual testing
1.2 Selenium
Selenium is an open source automation testing tool which is
used to test the web application across different platforms.
Selenium uses test scripts to execute the test cases within
the browser. It uses iframes and Java Scripts to embed the
test automation engine into the browser. This helps to run
and test same test scripts on multiple browsers on multiple
platforms. Selenium is basically used for functional
regression testing [2]. Selenium is a suit of components each
has its own testing purpose and these components are:
Selenium IDE, Selenium Remote Control, Selenium Web
Driver, and Selenium Grid [5].
Selenium components:
Selenium Integrated Development Environment (IDE)
Selenium Remote Control
Web Driver
Selenium Grid
Selenium Integrated Development Environment (IDE)
Selenium Integrated Development Environment is a Firefox
plugin that allow testers to record their actions. Selenium
IDE has a recording feature, which records user actions and
then exports them as a reusable scripts in one of the
supported programming languages that can be later
executed. As it only supports Firefox browser hence all the
user actions are recorded using a Graphical User Interface
with Firefox browser. These recorded actions thenexported
to various programming languages supported by selenium
and then executed on many browsers [5].
Selenium Remote Control
Selenium RC is the first automated web testing tool that
allow users to write web application UI test in multiple
programming languages. In selenium RC selenium opens
multiple browsers at the same time and then runs the saved
test-cases concurrently. Selenium RC not limitedtoselective
browsers it supports many new browsers hence user can
run many test-cases with own preferred language this helps
in enhancing the performance of test-cases covering all the
test scenarios and checks. Selenium RC Use many
programming languages like Java, C#, PHP, Python, Perl,
Ruby to create complex tests [5].
Selenium Web Driver
Selenium Web Driver is an automation framework tool that
supports multiple browsers and Ajax applications and
implements a more modern and stable approach in
automating the browser’s actions. Selenium web driver is
also known as selenium 2.0. It controls the browser by
directly communicating with it thereby controlling it from
the OS level. Selenium web driver supports multiple
Programming languagesto writethetestscriptssuchasJava,
C#, PHP, Python, Perl, Java [3]. Web Driver has a good
control on dynamic web pages where the elements of a web
pages change without the page itself being reloaded [5].
Selenium Grid
Selenium Grid is a tool used to run parallel tests across
multiple machines on different browsers simultaneously
which results in saved execution time. Selenium Grid uses
hub and nodes concept where hub acts as a central point of
selenium commands to each node connected to it. Selenium
Grid has only one hub and nodes are instances that are
attached to the hub which executes the tests [5].
2. SELENIUM WEB DRIVER: TESTING TOOL
Web Driver drives the web browser, controls the browser
action and uses the browser’s own engine to control it. Web
driver works with web elements of a web page. Initially it
locates the web elements on the web page and then
performs some action on it. It communicates with all page
elements in a more realistic way [3].
Locators in Web Driver
In Web Driver automation everything is identified with web
components as it is a web application automation tool. Web
Components are DOM Objects exhibit on the Web Page. To
perform operations on a Web Element we have to find the
Elements precisely [3].
As in the above articulation we need to determine some
locator to distinguish web component. "By" is the class, in
the class we have distinctive static techniques to recognize
components as beneath
1. id
2. name
3. className
4. tagName
5. cssSelector
6. xpath
7. linkText

8. partialLinkText
 By.id – Use “id” attribute to locate the
element.
 By.name - Use “name” attribute to locate
the element.
 By.className - Use “class” attribute to
locate the element.
 By.tagName - locates elementsbytheirtag
name
 By.cssSelector - finds elements based on
the driver’s underlyingCSSSelectorengine.
 By.xpath - locates elements via xpath.
 By.linkText - finds a link element by the
exact text it displays.
 By.partialLinkText -locateselementsthat
contain the given link text.
Synchronization in Web Driver
Web Driver has two types of waits –
• Implicit Wait – Is utilized to set the default holding up time
all through the program. This hold up is less complex to
code.
• Explicit Wait – Is utilized to set the waiting time for a
specific instance only.
Windows Handling in Web Driver
There are Two kinds of windows which we can handle using
Web Driver –
1) HTML Windows
2) Pop-Ups/Alerts
HTML Windows
Many Web Applications has different windows. Web Driver
manages moving between named windows using the
“switchto()” method.
Alerts
Alerts can be handled using four methods –
 accept () – this method is used to accept and close
the alert box.
 dismiss() – this method is used to reject and close
the alert box.
 gettext()– this method is used to retrieve the
message of the alert box.
 sendKeys() To write some text to the alert
Programming using Web Driver
Web Driver handles Keyboard operations and Mouse Event
operations. It contains the Actions classes that are required
when executing these events [6].
Below are the most commonly used keyboard and mouse
events provided by the Actions Class
Method Description
clickAndHold() It performs Click operation
without discharging at the
present mouse region
contextClick() Performs a context-click at
the current mouse area.
doubleClick() Performs a double click at
the current mouse area.
dragAndDrop(source,
target)
It Performs click and hold
operation at the region of
the source control, at that
point moves to the region
of the target control, at that
point discharges the mouse
dragAndDropBy(source,
x-offset, y-offset)
Performs click-and-hold at
the area of the source
element, moves to a given
offset, and then releases
the mouse.
keyUp(modifier _key) Does a key release.
moveByOffset(x-offset, y-
offset)
It performs Moving
operation on mouse from
its present position to the
provided offset.
release() Releases the pressed left
mouse button at the

present mouse location
sendKeys(onElement,
charsequence)
Sends a sequence of
keystrokes onto the
element.
Limitations
However, despite all advantages of selenium web driver, it
has some limitations. Selenium web driver has no built in
report generation functionality. Selenium web driver hasno
built in screenshot generation functionality. It is dependent
on the third party tool for report and screenshot generation
[4].
3. FUTURE WORK
There is scope of running scripts at the background without
disturbing the foreground processes so testercanwork with
different task along with running the test scripts at the
background. It will help in reducing the execution time by
executing the test cases concurrently in multiple browsers
on multiple machines at the background what we needto do
is to implement the code that will support the Multithread
concept and minimizing the browser and run at the
background. The future Implementation picture looks like

4. CONCLUSION
Selenium Web Driver is a tool forin-WebApplicationtesting,
begun by just contemplation and now it is being utilized
effectively by both the engineers and clients. The most
essential highlight of this tool is that it additionally
encourages the testing of web applications alongside
enhancing testing speed and reducing execution time for
repetitive test cases. Selenium Web Driver is positively an
advantage for any individual who is hoping to include an
effective web testing tool to their toolbox.
