Selenium
features
•
Selenium
is an open supply and portable web testing Framework.
•
Selenium
IDE provides a playback and record feature for authoring tests without the
necessity to learn a test scripting language.
•
It
is considered as the leading cloud-based testing platform that 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 varied operative 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,
web someone, Edge, Opera, Safari, etc.
•
It
also supports parallel test execution that reduces time and will increase the Selenium Training
in Marathahalli efficiency of tests.
•
Selenium
can even be integrated with testing frameworks like TestNG for application
testing and generating reports.
•
Selenium
needs fewer resources as compared to different automation test tools.
•
WebDriver
API has been indulged in selenium that is one of the most important
modifications done to selenium.
•
Selenium
web driver doesn't need server installation, check scripts act directly with
the browser.
•
Selenium
commands are classified in terms of various classes that create it easier to
grasp and implement.
•
Se
remote control (RC) in conjunction with WebDriver API is known as Selenium 2.0.
This version was designed to support the colorful sites and Ajax.
Limitations
•
Selenium
doesn't support automation testing for desktop applications.
•
Selenium
needs high ability sets so as to modify tests a lot of effectively.
•
Since
Se is open source software, you have to rely on community forums to get your
technical problems resolved.
•
We
can’t perform automation tests on web services like SOAP or REST using Se.
•
We
ought to know at least one of the supported programming languages to make tests
scripts in Se WebDriver.
•
It
doesn't have inherent Object Repository like UTF/QTP to take care of
objects/elements in centralized location. However, we will overcome this
limitation using Page Object Model.
•
Selenium
doesn't have any built-in reporting capability; you've got to rely on plug-ins
like JUnit and TestNG for test reports.
•
It
isn't possible to perform testing on pictures. We need to integrate Se with
Sikuli for image based testing.
•
Creating
test environment in Se takes longer as compared to vendor tools like UFT, RFT,
Silk test, etc.
•
No
one is responsible for new features usage; they'll or might not work properly.
•
Selenium
doesn't give any test tool integration for test Management.
Selenium’s
Tool Suite
Selenium
isn't simply a single tool however a collection of software’s, each with a
special approach to support automation testing. It includes of 4 major elements
that include:
1.
selenium
Integrated Development environment (IDE)
2.
selenium
remote control (Now Deprecated)
3.
WebDriver
4.
selenium
Grid
1. Se
Integrated Development surroundings (IDE)
Selenium IDE
is enforced as Firefox extension that provides record and playback practicality
on test scripts. It permits testers to export recorded scripts in several
languages like HTML, Java, Ruby, RSpec, Python, C#, JUnit and TestNG. You’ll
use these exported script in Se RC or Webdriver.
2. Se
remote control
Selenium RC
(officially deprecated by selenium) permits testers to put in writing
machine-driven web application UI test in any of the supported programming
languages. It also involves an HTTP proxy server that permits the browser to
believe that the web application being Selenium Training
In Marathahalli with placement tested comes from the domain provided
by proxy server.
3. Se
WebDriver
Selenium
WebDriver (Selenium 2) is that the successor to Se RC and is by far the most
necessary part of Se Suite. Se WebDriver provides a programming interface to
form and execute test cases. Test scripts are written so as to spot web
components on sites and so desired actions are performed on those components.
Selenium
WebDriver performs a lot of faster as compared to Se RC because it makes direct
calls to the web browsers. RC on the opposite hand wants an RC server to
interact with the web browser.
Since,
WebDriver directly calls the ways of various browsers therefore we've got
separate driver for every browser. Some of the foremost wide used web drivers
include:
·
Mozilla
Firefox Driver (Gecko Driver)
·
Google
Chrome Driver
·
Internet
explorer Driver
·
Opera
Driver
·
Safari
Driver
·
HTML
Unit Driver (a special headless driver)
4. Se Grid
Selenium
Grid is also an important part of Se Suite that allows us to run our tests on
totally different machines against different browsers in parallel. In simple
words, we can run our tests at the same time on different machines running
different browsers and operating systems.
The Hub is
taken into account as master of the network and the alternative is the nodes.
Hub controls the execution of test scripts on varied nodes of the network.

At TIB Academy, candidates will be getting
practical oriented Selenium Training
in Marathahalli. Live projects with real time
examples are available.
