History of Selenium Automation Testing

What exactly is Selenium? - Among the hottest API (Framework) for performing practical automation testing of a Web based program on multiple browsers, OS and support multiple languages.

Selenium is a library or a group of classes, interfaces and methods, a job that's already assembled by some business and is ready for all of us to use in our project.

Before we begin taking care of Selenium Tutorials we have to comprehend how API functions and how we can access functionality in the APIs.

Initially started by ThoughtWorks by the programmer Jason huggins with Selenium 1.0 version that comprises element Selenium IDE & Remote Control (RC). Unlike every automation tool IDE offers a record and playback feature and is add-on to Firefox.

Not much things can be achieved by Record and play therefore real Selenium examiner don't favor using IDE much and rely largely on the coding component which was attained through RC.

The design designed was injection of JavaScript on the browsers and was not completely supported on bonded browsers, also the API was too little to manage complex functionalists.

He realized all the challenges faced in RC and built a powerful API by removing the JavaScript injection in the architecture and replacing with genuine browser native course communicating by creating different groups for each browser. For example:

If you'd like to run automation evaluations on IE then there's a category called InternetExplorerDriver which you should be using. Even to support testing on Android and Iphone groups that have been created was AndroidDriver and IPhoneDriver but the functionality was limited to WebBased automation selenium testing only.

Not only this, the WebDriver API itself is quite tremendous and can manage many complicated situations easily and later on named as Selenium 2.0 which was formally started on July 2011. Check out for download Selenium and installing Selenium .

Another element was launched with Selenium 1.0 initially which is Grid1 and with WebDriver Grid2. Grid supports cross platform parallel testing on multiple browsers / OS at precisely the same time by creating distinct nodes and hub you'll be able to execute and spread your test cases to multiple machine for concurrent execution at the exact same time.

With Selenium online training (course details), we take real time examples and train you on actual frameworks such as Data Driven, Hybrid, Page Object model using JUnit, TestNG along with other API integration.

Online Selenium Training Trainers will not be full time employed trainer, We are a team of working professionals and are linked with CMM level organization in Quality assurance field itself that's the only reason our teaching includes examples from real-time scenarios and execution simply. These trainers also provide Selenium videos and Selenium video tutorials.

Selenium RC:

• It's easy as well as little API. These API's are less Object oriented.
• Selenium RC is slower since it uses a JavaScript application called Selenium Core.
• that directly controls the browser, not you.
• Selenium Core, just like other JavaScript codes, can get handicapped elements.
• Required to start server before executing the test script.
• It's standalone java application which permit you to run Html test suites.
• It needs a real, visible browser to operate on.
• It doesn't supports of transferring mouse cursors.
• Selenium RC Has Built-In Test Result Generator. Selenium RC automatically generates an HTML file of evaluation results.
• It doesn't supports listeners
• Selenium RC wants the help of the RC Server to be able to do so.
• It does not support to check iphone/Android programs.
• Selenium RC can support new browsers

Selenium Web driver :

• As compared to RC, it really is bit complex and big API. API's are entirely Object oriented
• Web Driver is faster than Selenium RC since it speaks straight to the browser uses the browser's own engine to control it.
• Web Driver interacts with page elements in a more realistic way. It interacts natively with browser Program.
• Does not required to start server before executing the test script.
• It real core API which has binding in a range of languages.
• Web Driver can support the headless HtmlUnit browser.
• It supports of transferring mouse cursors.
• Web Driver has no builtin command that automatically creates a Test Results File.
• It supports the enactment of listeners
• web Driver directly talks to the browser
• It support to test iphone/Android applications
• It cannot easily support new browsers

Selenium and Its Introduction

Today, software testing and developing is becoming significant livelihood choice for fresher’s as well as experienced professionals. Software testing tools may be used on the basis of the testing demands.

Selenium is the most complex automation testing tool associated services through several development phases and useful for validating web browsers. This automation tool is created for testing web applications where are needed to run browser automation and this testing tool is loaded with various packages.

Selenium is compatible with all the web browsers (Firefox, Google Chrome and Internet Explorer) and operating systems (Windows, Linux, Macintosh, etc.) without any compatibility problems. 

This automation validation tools lets you write validation case in all popular programming languages including Java, .Net, Python, VBScript, PHP, etc. Selenium IDE permits validation professionals for test, recording and solving evaluations readily. You can arrange all validation components utilizing the Selenium Remote Control. 

Selenium Webdriver

Selenium is its own accessible for users at free of charge and an open source automation program. You no need to concern yourself with any trail or licensing problems. This automation is tool is very simple download, install and integrate with your applications validation period.

Being an open source validation program, selenium is preferable option among freelancer validation professionals and applications validation businesses. It provides tremendous employment prospects for professionals powerful in selenium automation.

When a software testing team is in automating a testing procedure involved, Selenium that's a technology-intensive testing program plays an important function for making the whole procedure a great success.Selenium training is great need due to a lot of advantages of the program. 

As a mobile software testing framework for internet programs, Selenium assistance without obtaining knowledge of a test scripting language, in carrying out evaluations. It provides DSL or Domain Specific Language to write evaluations in several well known programming languages like Java, PHP, Perl, C#, etc. 

Evaluation playback could be carried out in most present day internet browsers. Selenium uses Windows, Linux, and Mac operating systems at the same time.

Pupils also can get twenty-four hours a day and seven days a week access over the web to Selenium online training. There's absolutely no pressure to obey a certain program and pupils may attend courses almost at whatever time appropriate for them. Online Selenium training also let working professionals without disturbing their work life considerably to learn. 

Just in case you pass up on a few courses that are significant, there isn't any need to stress as it is possible to benefit from innumerable repeat of the courses.

Selenium is a collection of software which supports immediate development of test automation for internet programs that are based. It's the choice of record/playback software for writing evaluations with no need of evaluation scripting language (Selenium IDE). 

It supports multiple browsers (Firefox, Opera, and Google Chrome) and multiple platforms (Microsoft, Linux, and Macintosh).It additionally provides a Domain Specific Language - Selenese.

Selenium is a web Automation tool which can used to do testing EXCLUSIVELY on Web Applications. not Windows based applications.

You will find others tool which can be used to automate both web applications and windows applications like QTP (Quick Test Professional). As every one mindful that QTP is Selenium AND Licensed Tool is Open source application, download it configures it and love.

This really is the primary reason Selenium every time they need to automate Web applications is chosen by all of the firms.

Selenium has the below elements:

Selenium IDE : Which is a firefox plugin which deals with and playback mechanism? User can create scripts that are simple and export to selenium Webdriver or RC.

Selenium RC: Is a tool which allows automating web application using some of the programming language that supports.

Selenium Webdriver : It makes direct calls to the browser using each browser's native support for automation.

Where itself may change with no page Webdriver was designed to support dynamic web pages like Ajax.

Selenium Grid : Is a server which allows web browser instances to be used by tests.

You will find others tool which may be used to automate both web applications and windows applications like QTP (Quick Test Professional). As everyone conscious that QTP is Licensed Program AND Selenium is Open source software, download it appreciate and configure it.

Here is the most important reason all of the firms pick Selenium tool whenever they need to automate Web applications

As a beginner, if you'd like to know selenium, it is that easy, you just start using Selenium IDE which is a Firefox plug-in, used to record and play the script. This is just for practice, and you also can learn in what way the commands that are used to run the script in IDE.

But remember IDE itself isn't enough for powerful test case. Because it cannot support looping concepts and and you cannot customize it for your needs.

Only at that point of time, you may start using Webdriver with the programming language that you are comfortable with.

As it's from long time in the industry, we favor Java and there are many on-line forums which provide Webdriver with Java with support.

Selenium WebDriver training lets you leverage the energy of multiple programming languages (e.g. C#, Java, PHP, Perl, Python, Ruby) to drive web browsers to create robust regression automation and scale / spread test scripts across many environments. 

Selenium WebDriver is the successor of Selenium Remote Control. Selenium WebDriver supports dynamic web pages where page components may shift with no page refresh through Ajax.

The program industry is facing nothingness for specialists in the applications modules that are complex and keeping this in view reputed applications Selenium training institutes are providing online Selenium tutorials in addition to routine training courses to improve their career chances on the market. 

In this event, you are buying flexible and live Selenium training program the online tutorials would be the most suitable choice as they're intended for self learning covering all the theories on the job oriented together with module and with practical training stuff.

Characteristics: Listed below will be the options that come with Selenium testing:

Selenium testing supports Cross Browser Testing and so it be run on multiple browsers.

It enables scripting like C#, PHP, Java and Python.

Its declaration statements give an efficient method of comparing real and expected outcomes.

It's inbuilt reporting mechanism.

Using Selenium as Test Automation tool reduces the cost incurred and additionally ensures quicker delivery. So it's cost effective and additionally not time consuming which shows that it is a typical automation tool for regression.
