Benefits of Learning Selenium

What is Selenium?




Selenium Testing is one popular automation testing tool that's wont to automate the browsers moreover as web applications. Using Selenium, one can test web applications with multiple browsers and thus make sure of the quality of web applications.

Selenium is an open-source project which allows the developer and testers to develop the functional tests that drive the browser. It also records workflows and helps the developers in preventing future regression of code.

Selenium can work on any browser which supports JavaScript because it has been built using JavaScript.

What is Automation Testing?

Investing an enormous amount of your time and money on large testing teams to create sure the appliance works as per the need is not possible. But the developers want to make sure their code works because it is predicted to figure. To do so, the developers are currently employing a multitude of testing frameworks that don’t demand much of their time. Selenium is one of every of the foremost popular automation testing frameworks that are currently in use all around the globe.

What is Selenium IDE?

Selenium IDE (Integrated Development Environment) may be a Firefox add-on that helps in using the initial Selenium Core without copying Selenium Core onto the server.

Selenium IDE was developed using JavaScript. this permits it to interact with DOM (Document Object Model) by using the native JavaScript calls.

Selenium IDE allows the developers and testers to record the actions they perform as they follow the workflow that must be tested.

Selenium WebDriver

There are certain limitations of Selenium 1 thanks to which WebDriver came into use. Here are a number of explanations why testers and developers are using WebDrivers.

Better control is achieved on the browser and browser-specific implementations will be implemented.

The developer can adhere to the object-oriented programming fundamentals and revel in a much better programming experience.

What is WebDriver?

WebDriver is nothing but an online automation framework that may allow you to execute the tests against any browser (not just Firefox).

WebDriver lets the tester and developer use any programming language to make the test scripts which isn't possible by using Selenium IDE.

The Programming Languages that are supported by WebDriver are

  • Java
  • .Net
  • Ruby
  • Python
  • PHP
  • Perl

However, you would like not to know all of those programming languages. you simply have to know one in every one of them.

Difference between Selenium 1 and Selenium 2

Let us observe the features of Selenium 1 and Selenium 2 individually that clearly enables you to form out the difference.

Selenium 1

  • It supports only real browsers. It doesn't support HTML Unit. It needs a graphical desktop environment.
  • It follows the approach that's supported JavaScript.
  • In Selenium 1, you wish a proxy application to regulate the browser while performing unit tests.
  • It is limited by the JavaScript security model of the browser.
  • It makes use of complex API.
  • It has API methods for specific HTML elements.

Selenium 2

  • Selenium 2 was created from the WebDriver Project and Selenium 1.
  • The WebDriver controls the browser directly. there's no need of using Selenium RC, which suggests you are doing not require a proxy application to manage the browser.
  • Selenium Grid and Selenium RC of Selenium 1 are merged into the Selenium Server.
  • Selenium 2 supports all varieties of browsers, including mobile browsers of Android and iPhone like earlier said.

Why must you learn Selenium over other testing tools?

The recognition of Selenium has skyrocketed within the current years and also the internet has seen the start of quite a lot of Selenium Training Video Tutorials and Selenium WebDriver online training courses. But if you're wondering why you ought to attend Selenium Training in Pune over other testing courses, here are a number of the explanations accountable for its reliability.

Selenium is an open-source testing tool

Selenium has the advantage of being open source. The users can share, extend, and modify the code that's available. this protects lots of your time and energy for the programmers which directly improves their productivity.

Platform Portability

The programmers can write code without having to stress about the platform on which the code has got to run. The Selenium automation testing gives the programmer the liberty to jot down code on any platform because it has the power to run on different platforms moreover as browsers.

Remote Control

Selenium has the special feature of remote which lets the testers to form and test the infrastructure that's spread across various locations very easily.

Flexibility

Most of the software programmers prefer keeping the testing within the program. By making use of Selenium, all the tests will be regrouped and refactored as per the necessities. This avoids duplication of code and allows the programmer to create quick changes to the code. The test is efficiently managed using Selenium.

This new automation toolset made something that was previously very difficult and fragile — automation of tests during a browser — just a touch easier to make and plenty more useful. These changes and developments in Selenium also had the side effect of making a community of open source and commercial tools. Selenium is now becoming the actual browser testing tool. you'll be able to find out how to urge started with Selenium here.

Selenium is one every of the foremost desirable automation tools for both enterprises and teenagers to increase their careers in this regard. Before discussing the importance of selenium, let’s have a bird’s eye view about what it's. What is Selenium? Selenium is an open-source automated testing suite to check web applications over diverse browsers and platforms. It gives a playback tool for authoring functional tests. So, the tester won’t put extra effort into learning a test scripting language. Besides, Selenium facilities with “Selenese” (a test domain-specific language) to put in writing scripts. Read more Selenium Tutorials. Selenium Advanced Training These scripts will be created in any of the mentioned specific programming languages like Java, Python, C#, PHP, Ruby, Perl & .Net.
