The Selenium Training Classroom or Online mode is currently in source
Of all the software testers, since its beginning, Selenium has been
Known for several of its good features, in this tutorial, you are
Promised to get a basic understanding of Selenium and whether you should
Go for selenium training.
Selenium is for Software Testing Professionals. It is better understood and
Easy to learn, if learner has basic idea of Java or any other object-oriented
Programming language, Slight understanding of testing concepts can be the
Spike in the cap.
Introduction:
Selenium is an open source automated and portable software testing tool. It
Used for testing of web applications. Selenium can operate across various
Operating systems and different browsers, it is not a single tool but a set of
Different tools that aid testers in automating the web based applications
Here the following tools are easy to understand to make selenium,
Selenium IDE:
The Integrated Development Environment of Selenium is a Firefox plug-in which
Allows the testers to record all their activities as they follow the workflow
That they need to test because It offers graphical user interface that records the
User Firefox actions, this can only use with Firefox browser and other
Browsers are not supported.
Selenium RC:
Remote Control is a testing framework that lets testers Perform simple browser
actions and linear execution. It completely uses the Strengths of programming
languages like Python, PHP, Java, PERL and Ruby That helps in the creation of
more complex tests.
Selenium Web Driver:
Selenium Web Driver is the successor of Selenium RC. It directly sends commands
To the browser and then the results retrieved.
Selenium Grid:
Selenium Grid is a tool which used to run tests parallel across different
Machines and different browsers, these results in the reduction of execution time.
Advantages of Selenium:
1. It can extend for several different technologies that expose DOM
2. Selenium is an open source tool
3. It also can execute scripts on different operating systems
4.It has the ability to execute scripts across different browsers
5.It supports mobile devices.
6.It executes tests within the browser.
Disadvantages of Selenium:
We have few disadvantages of selenium those given below,
1. It does not have the ability to control access within the browser
2. Selenium supports only web based applications
3. It does not have test report generation
4. The uses has to depend on programming language for parameterization
5. It does not have IDE due to which the development of script becomes slow
6. It does not have the feature of recovery scenario
