Selenium is an open source test robotization suite utilized for
computerizing electronic applications. It bolsters mechanization crosswise over
various programs, stages and programming dialects.
Utilizing selenium, we can mechanize the useful tests and
effortlessly incorporate them with Maven, Jenkins and other form mechanization
and continuous reconciliation instruments.
Parts of
Selenium Suite:
Selenium Suite involves the accompanying four segments
·
Selenium IDE - Selenium IDE is an extra of Firefox program that
gives record and play back usefulness. Its utilization is constrained and test
contents produced are not extremely hearty and compact.
·
Selenium RC - Selenium Remote Control(RC) is authoritatively
belittled by Selenium. It used to require an extra server for running the
computerization contents and had numerous impediment.
·
Selenium WebDriver - By far the most vital part of Selenium Suite.
It gives diverse drivers to various programs and backings different programming
dialects.
·
Selenium Grid - Selenium Grid is likewise a critical piece of
Selenium Suite. selenium
training in Bangalore - It helps in appropriated running of selenium
tests in parallel over numerous remote machines.
Points of
interest of Selenium:
How about we now observe a portion of the benefits of Selenium-
·
Selenium is open source, there is no authorizing taken a toll for
its utilization.
·
Scripting should be possible in a large portion of the broadly
utilized programming dialects like Java, C#, Ruby and Python
·
It backings the vast majority of the prominent programs like
Chrome, FireFox, Internet Explorer, Opera and Safari.
·
Selenium IDE part of Selenium suite gives record and playback
include utilizing which non-software engineers can likewise compose computerization
contents.
·
Selenium Grid helps in parallel and appropriated testing.
Impediments
of Selenium:
A portion of the impediment of Selenium are-
·
Selenium does not give desktop application computerization
bolster.
·
Web Services - REST or SOAP can't be computerized utilizing
selenium.
·
Selenium webDriver requires programming dialect prerequisite for
content creation.
·
For performing regular assignments required in mechanization like
logging, perusing keeping in touch with outer documents we need to depend on
outside libraries.
Selenium
WebDriver:-
Selenium
Webdriver (otherwise called Selenium 2.0) is a standout amongst the most
broadly utilized apparatus for computerizing web applications. It mechanizes
the programs by calling their local technique straightforwardly not at all like
Selenium RC which infuses javascript in programs for computerization.
Consequently, webdriver is
significantly speedier than Selenium RC and furthermore, can deal with
situations like cautions, pop-ups, ajax solicitations, console and mouse
activities effortlessly. It likewise bolsters the vast majority of the
prominent programming dialects like - Java, C#, Python, Ruby and so forth.
Since, webdriver straightforwardly calls the techniques for various programs
subsequently we have isolate driver for every program. A portion of the
generally utilized drivers in selenium are - FirefoxDriver, ChromeDriver,
InternetExplorerDriver, SafariDriver and HtmlUnitDriver.
Page Object
Model:
Page Object Model outlines design
in UI computerization testing. Before beginning with Page Object Model, how
about we initially recognize what configuration designs are.
Configuration
design:
A design is a bland answer for a
typical programming plan/engineering issue. Usage of these outline designs
prompts incorporation of best practices and best arrangement, advanced over the
time by others while working with comparable issues.
Page Object
Model in Selenium
A Page Object Model is an outline
design that can be actualized utilizing selenium webdriver. It basically models
the pages/screen of the application as items called Page Objects, every one of
the capacities that can be performed in the particular page are typified in the
page protest of that screen. Along these lines any change made in the UI will
just influence that screens page protest class therefore abstracting the
progressions from the test classes.
Points of
interest of utilizing Page Object Model:
·
Increases code reusability - code to work with occasions of a page
is composed just once and utilized as a part of various experiments
·
Improves code viability - any UI change prompts refreshing the
code in page question classes just leaving the test classes unaffected
·
Makes code more lucid and less weak
Making a Page
Object Model in Java:
Here, make a robotization system
actualizing Page Object Model utilizing Selenium with Java.
Assume we need to test a spurious
application with just a login page and a landing page. To begin with that,
first need to make page objects for every single accessible page in our
application - LoginPage.java and HomePage.java. At that point will make a test
class that will make occasion of these page protests and conjure there
strategies to make tests.
