2. Introduction:-
•Selenium is a prevalent open-source electronic
mechanization instrument. This class will make you
an expert in Selenium Automation.
Selenium suite is contained 4 essential parts;
1. Selenium IDE
2. Selenium RC
3. Web Driver
4. Selenium Grid.
• The client is relied upon to pick admirably the
correct Selenium apparatus for his/her needs.
Selenium IDE is appropriated as a Firefox module
and it is less demanding to introduce and utilize.
3. Selenium IDE:
•Selenium coordinated advancement condition, acronym as
Selenium IDE is a robotized testing device that is discharged as a
Firefox module.
•It is one of the most straightforward and least demanding
apparatuses to introduce, learn and to proceed with the formation of
test contents.
•The device is laid on a record and playback key and furthermore
permits altering of the recorded contents.
•The most noteworthy part of utilizing selenium IDE is that the
client isn't required to have any earlier programming information.
•The base that the client needs is the little colleagues with HTML,
DOMS and JavaScript to make various test contents utilizing this
device.
4. •Being a Firefox module, Selenium IDE bolsters just
Firefox, therefore the made test contents could be executed
just on Firefox.
• A couple of more escape clauses make this device
improper to be utilized for complex test contents. Along
these lines, different apparatuses like Selenium RC, Web
Driver comes into the photo.
•Selenium IDE test cases can be traded into following
configurations/programming languages.java (IDE sent out
in Java),rb (IDE traded in Ruby),py (IDE traded in
Python),cs (IDE traded in C#)
5. The whole Selenium IDE content creation process can
be grouped into 3 lumps:
Process 1: Recording – Selenium IDE helps the client
to record client connections with the program and along
these lines the recorded activities in general are named
as Selenium IDE content.
Process 2: Playing back – In this area, we execute the
recorded content in order to confirm and screen its
dependability and achievement rate.
Process 3: Saving – Once we have recorded a steady
content, we might need to spare it for future runs and
relapses.
6. Web Driver:-
•Web Driver is a standout amongst the most effective and
famous apparatuses of Selenium toolbox. WebDriver
comes as a broadened variant of Selenium RC with
unnecessary favorable circumstances and addresses a
significant number of its restrictions.
• Web Driver stretches out its help to numerous most recent
programs and stages, not at all like Selenium IDE.
•Web Driver additionally doesn't require Selenium server to
be begun preceding execution of the test contents, not at all
like Selenium RC.
7. •Selenium RC in conglomeration with WebDriver API is known as
Selenium 2.0.
•Selenium was so created with a specific end goal to help dynamic site
pages and Ajax calls.
• It additionally underpins different drivers to practice online versatile
testing.
Web Driver Architecture:-
•WebDriver is an electronic testing instrument with an inconspicuous
contrast with Selenium RC.
•Since the device was based on the major where a disconnected customer
was made for every one of the web programs, no JavaScript Heavy
lifting was required as we talked about in our first instructional exercise.
•WebDriver makes guide calls to the Web program and the whole test
content is executed in this design. WebDriver utilizes the programs
support and capacities to mechanization.
8. Extraordinary Cases when Selenium Server is required with
WebDriver:-
•At the point when the client wishes to execute test contents on
the remote machine.
•At the point when the client wishes to execute test contents on
HtmlUnit Driver.
•At the point when the client wishes to execute test contents on
numerous stages.
9. •WebDriver is an absolutely question arranged structure that
deals with OS layer.
•It uses the program's local similarity to robotization without
utilizing any fringe substance.
• With the expanding request, it has picked up a huge
prevalence, client base and has progressed toward becoming by
a long shot a standout amongst the most broadly utilized open
source computerization testing apparatuses.
•WebDriver bolsters a differing scope of web programs and
their renditions.
•It underpins all the regular programs notwithstanding some
remarkable and uncommon programs like HtmlUnit program
dissimilar to Selenium RC and Selenium IDE.
10. •HtmlUnit Browser executes the test contents practically
equivalent to different programs with the exception of the way
that it keeps running in the headless mode i.e. GUI-less mode
and the client won't have the capacity to see the test content
execution.
•Said that the test content execution unfolds in headless mode,
in this way the execution speed takes a roll and revives the
execution.
•WebDriver additionally underpins online portable testing. In
this way it gives AndroidDriver and IphoneDriver to back online
versatile testing.
11. JUnit:-
•JUnit is an open source unit testing device and used to
test little/extensive units of code.
•To run the JUnit test you don't need to make a class
protest or characterize the primary technique.
• JUnit gives attestation library which is utilized to assess
the test outcome. Comments of JUnit are utilized to run
the test technique.
•JUnit is likewise used to run the Automation suite
having various experiments.
12. TestNG:-
•TestNG is a propel system planned in an approach to use the
advantages by both the designers and analyzers. For individuals as
of now utilizing JUnit, TestNG would appear to be the same with
some propel highlights.
•With the initiation of the structures, JUnit picked up a
tremendous notoriety over the Java applications, Java designers
and Java analyzers, with astoundingly expanding the code quality.
•Despite being an easy to use and straightforward framework,
JUnit has its own limitations which give rise to the need of
bringing TestNG into the picture.
•TestNG was created by an acclaimed programmer named as
“Cedric Beust”. TestNG is an open source framework which is
distributed under the Apache Software License and is readily
available for download.
13. •Talking about our requirement to introduce TestNG with
WebDriver is that it provides an efficient and effective test result
format that can, in turn, be shared with the stakeholders to have a
glimpse of the product’s/application’s health thereby eliminating
the drawback of WebDriver’s incapability to generate test reports.
•TestNG has an inbuilt exception handling mechanism which lets
the program to run without terminating unexpectedly.
•
•Both TestNG and JUnit belong to the same family of Unit
Frameworks where TestNG is an extended version to JUnit and is
more extensively used in the current testing era.
14. Highlights of TestNG:-
•Support for explanations .
•Support for parameterization .
•Propel execution technique that does not require test suites to be made .
•Support for Data Driven Testing utilizing Data suppliers .
•Empowers client to set execution needs for the test techniques .
•Backings danger safe condition when executing different strings
•Promptly bolsters joining with different instruments and modules like form
apparatuses (Ant, Maven and so forth.), Integrated Development Environment
(Eclipse).
•Encourages client with powerful methods for Report Generation utilizing ReportNG.
15. Selenium customer API:-
As an other option to composing tests in Selenese, tests can likewise
be composed in different programming dialects. These tests at that
point speak with Selenium by calling techniques in the Selenium
Client API. Selenium as of now gives customer APIs to Java, C#,
Ruby, JavaScript and Python.
As a contrasting option to composing tests in Selenese, tests can
likewise be composed in different programming dialects. These
tests at that point speak with Selenium by calling strategies in the
Selenium Client API.
16. •Selenium right now gives customer APIs to Java, C#, Ruby,
JavaScript and PythonWhile Selenium IDE may appear a gainful
and productive instrument for composing experiments, it needs
numerous fundamental highlights of a testing apparatus:
1. Restrictive articulations
2.Circles,Logging
3.Exemption taking care of
4.Revealing
5.Test installations and information driven tests
6.Test conditions
7.Taking screen captures
Selenium RC is the response to an all the more intense test-suite
for your applications.
It takes after a customer/server display enabling customer libraries
to execute tests on a program controlled by the server.
17. Selenium Grid:-
•Selenium Grid is utilized to run various tests all the
while on various programs and stages.
• The center point is the essential issue wherein you
stack your tests.
•Hubs are the Selenium occurrences that will execute
the tests that you stacked on the center point.
