• SELENIUM is a free (open-source) automated
  testing framework used to validate web
  applications across different browsers and
  platforms. You can use multiple programming
  languages like Java, C, Python etc to create
  Selenium Test Scripts. Testing done using the
  Selenium tool is usually referred to as Selenium
  Testing.

History Selenium
was originally developed by Jason Huggins in 2004
as an internal tool at ThoughtWorks. Huggins
was later joined by other programmers and
testers at ThoughtWorks, before Paul Hammant
joined the team and steered the development of
the second mode of operation that would later
become "Selenium Remote Control" (RC). The tool
was open sourced that Year. The name Selenium
comes from a joke made by Huggins in an email,
mocking a competitor named Mercury, saying that
you can cure mercury email took the name and ran
with it.

Need of Automation Technology Every
software development group tests its products,
yet delivered software always has defects. Test
engineers strive to catch them before the product
is released but they always creep in and they
often reappear, even with the best manual testing
processes. Test automation software is the
best way to increase the effectiveness,
efficiency and coverage of your software
testing.

• 
  Features/Advantage of Selenium
• Selenium is an open source and portable Web
  testing Framework.
• Selenium IDE provides a playback and record
  feature for authoring tests without the need to
  learn a test scripting language.
• It can be considered as the leading cloud-based
  testing platform which helps testers to record
  their actions and export them as a reusable
  script with a simple-to-understand and
  easy-to-use interface.
• Selenium supports various operating systems,
  browsers and programming languages. Following is
  the list
• Programming Languages C, Java, Python, PHP,
  Ruby, Perl, and JavaScript
• Operating Systems Android, iOS, Windows, Linux,
  Mac, Solaris.
• Browsers Google Chrome, Mozilla Firefox,
  Internet Explorer, Edge, Opera, Safari, etc.

• 
  Limitations of Selenium
• Difficult to use takes more time to create Test
  cases.
• No reliable Technical Support from anybody.
• Difficult to Setup Test Environment when it
  compares to Vendor Tools like UFT, RFT, SilkTest.
• Limited support for Image Testing.

  Details of Selenium tool
• Selenium IDE (Integrated Development
  Environment)
• It is primarily a record/run tool that a test
  case developer uses to develop Selenium Test
  cases. Selenium IDE is an easy to use tool from
  the Selenium Test Suite and can even be used by
  someone new to developing automated test cases
  for their web applications. One does not require
  any special setup to get started with Selenium
  IDE. You just need to add the extension of your
  specific browser. Selenium IDE provides you with
  a GUI (Graphical User Interface) for easily
  recording your interactions with the website.
• Selenium IDE allows a user or a test case
  developer to create the test cases and test
  suites and edit it later as per their
  requirements. The development environment also
  provides the capability of converting test cases
  to different programming languages, which makes
  it easier for the user and does not mandate the
  need for knowing a specific programming language.

2. Selenium Remote Control (RC) It was the main
Selenium project that sustained for a long time
before Selenium WebDriver(Selenium 2.0) came into
existence. Now Selenium RC is hardly in use, as
WebDriver offers more powerful features, however
users can still continue to develop scripts using
RC. It allows us to write automated web
application UI tests with the help of full power
of programming languages such as Java, C, Perl,
Python and PHP to create more complex tests such
as reading and writing files, querying a
database, and emailing test results. Selenium RC
Architecture Selenium RC works in such a way
that the client libraries can communicate with
the Selenium RC Server passing each Selenium
command for execution. Then the server passes the
Selenium command to the browser using
Selenium-Core JavaScript commands. The browser
executes the Selenium command using its
JavaScript interpreter.

3. WebDriver It is a web automation
framework that allows you to execute your tests
against different browsers, not just
Firefox, Chrome (unlike Selenium IDE). WebDriver
also enables you to use a programming language in
creating your test scripts (not possible in
Selenium IDE). You can now use conditional
operations like if-then-else or switch-case. You
can also perform looping like do-while.

• Advantage of WebDriver over
  Remote Control
• WebDriver's architecture is simpler than
  Selenium RC's.
• WebDriver is faster than Selenium RC since it
  speaks directly to the browser uses the browser's
  own engine to control it.
• WebDriver interacts with page elements in a more
  realistic way. For example, if you have a
  disabled text box on a page you were testing,
  WebDriver really cannot enter any value in it
  just as how a real person cannot.
• WebDriver's API is simpler than Selenium RC's. It
  does not contain redundant and confusing commands.

4.Selenium Grid It is a part of the Selenium
Suite that specializes in running multiple
tests across different browsers, operating
systems, and machines in parallel. Selenium
Grid has 2 versions - the older Grid 1 and the
newer Grid 2. We will only focus on Grid 2
because Grid 1 is gradually being deprecated by
the Selenium Team.

• Selenium Grid Architecture
• Selenium Grid has a Hub and Node Architecture.
• The Hub
• The hub is the central point where you load your
  tests into.
• There should only be one hub in a grid.
• The hub is launched only on a single machine,
  say, a computer whose O.S is Windows 7 and whose
  browser is IE.
• The machine containing the hub is where the tests
  will be run, but you will see the browser being
  automated on the node.

• The Nodes
• Nodes are the Selenium instances that will
  execute the tests that you loaded on the hub.
• There can be one or more nodes in a grid.
• Nodes can be launched on multiple machines with
  different platforms and browsers.
• The machines running the nodes need not be the
  same platform as that of the hub.

• When to Use Selenium Grid?
• You should use Selenium Grid when you want to do
  either one or both of following
• Run your tests against different browsers,
  operating systems, and
• machines all at the same time. This will ensure
  that the application you are Test is fully
  compatible with a wide range of browser-O.S
  combinations.
• Save time in the execution of your test suites.
  If you set up Selenium Grid to
• run, say, 4 tests at a time, then you would be
  able to finish the whole suite around 4 times
  faster.
