Gain Hands on Experience in Testing Programs with Selenium!

What is Selenium Testing?

Selenium is an open source platform that automates the process of testing mobile and Web apps. It portrays how a person interacts with your web app by automating the process of filing in the forms, clicking on images and links and verifying that certain images open up properly.

It is not just a single tool but an array of software’s each of them for different testing needs of an organization. It has four components:

Selenium Integrated Development Environment- It is one of the simplest framework in the Selenium category and easiest it learn. It is a Firefox plug-in that you can install easily with other plug-ins.

Selenium Remote Control- It is the first automated web testing tool that allowed users to use a programming language they want.

Web Driver- It gives a more modern and stable approach in automating browser’s actions. It does not rely on JavaScript for Automation. It controls the browser by directly communicating with it. The languages it supports are C#, PHP, Python, Perl and Ruby.

Selenium Grid- It is a tool used along with Selenium RC to run parallel tests across different machines and browsers at the same time.

Selenium being a collection of different tools, it has been developed by different developers. Initially, it was created by Jason Higgins in 2004. He created a JavaScript Program and named it as JavaScript TestRunner. He then made it open source and renamed it as Selenium Core.

The seven basic steps to creating Selenium test script are:

• Create a Web Driver instance
• Navigate to a Web page
• Locate an HTML element on the Web page
• Perform an action on an HTML element
• Anticipate the browser response to the action
• Run tests and record test results using a test framework
• Conclude the test

Pros of Selenium

Because of its many advantages, Selenium has a wide usage in UI, regression, unit and acceptance testing. Because of the rapid test development it enables, it is quite popular for quick-cycle development methodologies such as Agile or Extreme Programming. Selenium is also popular with IT staff who automates repetitive, web-based administrative tasks.

·         Selenium has no upfront, out-of-pocket costs. It is a free download and support is  free too, although it is community- based.

·         Selenium tests are able to run under multiple browsers.

·         Although Selenium has its own script language, one is not limited to writing in that  

language since it can work with language bindings to support whatever the 

developers or testers are comfortable with including C#, Java, JavaScript, PHP,  

Python and others.

·         Selenium scripts are created by recording actions using the web application under  

test running in a browser. These scripts can be saved and re-run at any time. 

·         Selenium tests can be created manually through the use of web development tools

such as Firebug.

·         Selenium does not restrict QA’s choice of reporting tools, build systems or any 

other aspect of their testing framework.  

·         It also supports web applications that implement part of their functionality within the browser using JavaScript and AJAX technologies.

Cons of Selenium

·         Selenium is not a complete, comprehensive solution to fully automating the testing  

of web applications. It requires third-party frameworks, language bindings and so on 

to be truly effective.

·         Despite its acceptance of other test script languages, it demands higher-level

technical skills, such as programming, from QA team members.

·         It has no test management facilities. Test scripts are saved as simple files without

features. Organizing individual scripts in any fashion via a user interface requires

a third-party tool or a custom application.

·         Because native “Selenese” test scripts are not user-friendly in terms of readability,

they are difficult to modify. Many testers simply resort to discarding the original  

scripts and recording them again, which can be time consuming.

·         Selenium does not support test and result sharing in anything but a manual way.

·         There is no support for running tests in parallel on a single computer.

·         Selenium has technical issues with browsers other than Firefox. Furthermore, it

does not support conditionals, loops and has trouble finding locators without the

help of additional tools such as Firebug.

The selenium training institute in Delhi have expertise in developing the course that helps to learn effective web automation testing using the selenium test suit and automated scripts. One can learn about automation testing technique an strategies, creating automated scripts, performing test automation; basically helping you to learn through practical scenarios of testing with live examples.

The Selenium training in Delhi will help you to:

·         Create automated scripts for bug reproduction

·         Create scripts to cooperate in automation aided testing

·         Create regression tests

·         Scale and administer scripts across the different environments  

The training will not only give you a quick start in your automation career but will also help you in getting a high paid job. You will be provided free demo classes before the training to give you the feel of quality the training will provide.
