All web application developers should be
well-versed in Selenium, an open-source,
automated testing tool. Selenium automated
testing is the term used to describe testing
carried out with Selenium. Selenium, however, is
a group of tools that each serve a specific
purpose for Selenium automated testing. You will
learn everything there is to know about Selenium
and the numerous Selenium Automation Testing
tools in this tutorial.

Overview Let's first talk about the necessity for
Selenium automation testing and how Selenium came
to be, though, before we go into this Selenium
automation testing course.

Unfortunately, manual testing, which is an
essential step in the development of
applications, has numerous drawbacks, the most
significant of which is that it is a tedious and
repeated procedure. Jason Huggins, an engineer at
Thoughtworks, made the decision to automate the
testing procedure to get around these
difficulties. He created the JavaScriptTestRunner,
a JavaScript software for automating web
application testing. In 2004, the program's name
was changed to Selenium.
Selenium automation testing has the drawback of
only being able to test online applications,
leaving desktop and mobile apps out in the cold.
However, software and mobile applications may be
tested using tools like HP's QTP and Appium,
among others.
Tools for Selenium Automation Testing

• Selenium IDE
• Everything you need to know about Selenium IDE is
  covered in the following section of the Selenium
  Automation Testing Courses tutorial. The Selenium
  Integrated Development Environment (IDE) was
  created in 2006 by Shinya Kasatani. Typically, it
  is a simple user interface that logs user
  interactions so that automated test scripts can
  be created. It is a Chrome or Firefox plugin that
  is typically utilised as a prototype tool. It was
  primarily created to facilitate the rapid
  development of automation scripts.
• When Firefox upgraded to the new Firefox 55
  version, which did not support Selenium IDE, IDE
  ceased to exist in August 2017. A new version of
  the outdated Selenium IDE was been released by
  Applitools. The most recent version introduced
  various improvements, including
• script reuse for tests
• testing scripts for bugs
• Siderunner for selenium
• Control flow statements are allowed
• enhanced locating capabilities

6
Installing IDE First, launch the Firefox web
browser. Step 2 Select "Menu" from the top right
corner. Step 3 In the drop-down box, select
Add-ons. Step 4 Select Find additional add-ons
and enter "Selenium IDE" In Step 5, select Add to
Firefox. After installation, the Selenium IDE
symbol displays in the browser's upper right
corner. Upon clicking it, a welcome message is
displayed.   Recording a test We will learn how
to record a test in this section of the Selenium
automation testing course. Let's start by writing
a fresh test for a fresh project. Give your
project a name in this case, we'll call it demo
project. We need to specify a working URL first
before recording. Once the browser arrives at
this URL, the recording gets started. Go to the
Facebook login page now. You will be directed to
the Facebook page and can begin recording user
interactions there by clicking "Start Recording."
The user has the option to halt recording. Every
user action is captured and turned into a script.
7
Work Saved In the following section of this
Selenium Automation Testing tutorial, we'll cover
how to save your work. Click the save symbol in
the top-right corner of the IDE to save what
you've just done there. You will be asked to
provide the project a name and a location to save
it. One file with the a.side extension is
produced as a result.   Playback In-browser By
choosing the test you want to replay and hitting
the Play button in the Selenium automation
testing IDE, you may playback tests. You can use
the command-line-runner for cross-browser
playback.   Remote control for selenium (RC) This
Selenium automation testing tutorial also
discusses Remote Control, or RC, which is an
intriguing subject. It also discusses the primary
justification for the creation of RC. Selenium
Remote Control was developed by Paul
Hammant. Jason Huggins created a tool called
"JavaScriptTestRunner" in 2004 that was the
original name of Selenium-Core. It was a
collection of JavaScript functions that used the
built-in JavaScript interpreter in the browser to
decipher and carry out Selenese commands. The web
browser was then given an injection of
Selenium-Core.
8
Consider the JavaScript file test.js that
Google.com uses as an example. Within the
google.com domain, this software can visit pages
like google.com/mail or google.com/login. The
software, however, is unable to access components
on other websites, such as Yahoo.com. The web
browser and Selenium-Core required to be
installed locally in order for them to share the
same domain. This restriction is known as the
Same Origin Policy, and Selenium RC was created
to work around it. It "trickles" the browser into
thinking that Selenium Core and the web
application being tested have the same origin by
acting as a client-configured HTTP proxy. As a
result, Selenium RC is a Java server that allows
for the creation of application tests in a
variety of computer languages, including Java,
C, Perl, PHP, Python, etc. The Selenium-Core
JavaScript commands are passed to the browser by
the RC server after being received from the user
programme.   WebDriver for Selenium Everything
about Selenium WebDriver is covered in the
following section of the Selenium Automation
Testing tutorial. Selenium WebDriver, created by
Simon Stewart in 2006, was the first
cross-platform testing framework capable of
configuring and managing browsers at the OS
level. In order to design and execute test cases,
it acted as a programming interface.

• In contrast to Selenium RC, WebDriver works
  directly with the browser apps and doesn't need a
  core engine like RC. Additionally, WebDriver
  supports a number of programming languages,
  including Perl, PHP, Ruby, and Python. For
  managing Selenium automated testing, it can also
  be coupled with frameworks like TestNG and JUnit.
• The architecture of Selenium WebDriver is
  straightforward and simple to comprehend
• The test code written in any of the
  aforementioned programming languages and read by
  the driver is known as a "Selenium test script."
• Data can be transferred between a server and a
  client using the JSON Wire Protocol, which offers
  a transport method for doing so. For many types
  of web services, JSON Wire Protocol serves as the
  industry standard.
• Browser drivers To create a secure connection
  with the browser, Selenium utilises drivers that
  are unique to each browser.
• Browsers Selenium WebDriver supports a number of
  different web browsers for testing and using
  apps.
•  
• Tutorial for Selenium WebDriver -
• Install Java 8 or a later version by downloading
  it. Download and install the most recent Java
  development kit.
• Installing Eclipse or another Java IDE of your
  choice after downloading

10
Click on the most recent version in the
"additional downloads" section as you go down the
page. Zip files are what will be downloaded. In a
folder of your choice, unzip the file. Open the
eclipse file.exe after unzipping it. The
configuration of a workplace is the following
phase. Click the launch icon after choosing the
directory where you wish to keep all of your
projects. The IDE workbench seems something like
this after it has been launched. 3. Download the
Java client for Selenium WebDriver. Go to the
Selenium website's main page. Locate Selenium
Client and WebDriver Language Bindings by
scrolling down the page. To download the Java
Client Driver, click the image's "Download"
link. Download the file, then unzip it in a
directory. It contains of the Jar files needed
for Selenium WebDriver's IDE configuration. 4.
Download the browser driver. All browsers must be
supported by the automation scripts. The driver
files for each supported browser by Selenium are
included. To execute the scripts, these are
necessary. 5. Configure Selenium WebDriver - The
Selenium WebDriver must be set up with the
Eclipse IDE in order to complete the process. To
put it simply, we start a new Java project and
write our test script there.
11
Name your project, then choose the JRE you want
to use. Use of the default JRE is advised. Choose
it, then click "finish." The final and most
important step is to upload the Java executable
files that were downloaded Step 3. Right-click
on the Project and choose Configure Build Path
from the Build Path menu. After choosing
libraries, add external JARs. Select the two
executable JAR files by opening the folders where
you've saved your JAR files. To include them,
click on open. Click on the "libs" folder, then
"Select Files" and "Open." Click Apply and Close
after you are finished adding the library
files. With this, the Webdriver and Eclipse IDE
have been successfully configured. You can now
create your initial test script. To do so,
right-click the Src folder and select
"NewgtgtClass." Now let's construct a
straightforward test script that starts Firefox
and displays the Facebook home page. Below is a
script that you can use. The location of your
browser driver is the second argument to the
setProperty function, take note. In our
situation, the gecko driver has been installed.
As a result, we paste the path and the file's
name. Then select RungtgtRun As. Application in
Java

Selenium Grid You will learn all about Selenium
Grid, which was created by Patrick Lightbody to
reduce the execution time of Selenium Automation
Testing Training, in the following section of
this lesson on Selenium automation testing.
Selenium Grid facilitates parallel execution by
enabling test execution across several operating
systems and browsers. Grid is incredibly
adaptable and integrates with other elements of
the suite for concurrent performance.
13
The Grid is made up of a hub and multiple
connected nodes. Along with the test to be done,
it also collects data on the operating system and
browser that will be used. The Grid then selects
a node and passes the test to that node if it
complies with the specifications (browser and
platform). At this point, the node launches the
browser and carries out the Selenium commands
inside of it.   Conclusion You should now have a
better understanding of Selenium and how it
functions after reading this Selenium Automation
Testing lesson. In this lesson, you will discover
how to use Python with Selenium. You need obtain
course certification if you want to start a
profession as an automation engineer. Check out
