For all the things that we need to know in the internet, we need we need to take the support of the browser. If the application  (or) website is developed, it would not be launched immediately. It needs to undergo the testing phase and then the website is launched. During this testing phase, the tester uses different commands for the purpose of validation.

Commands of selenium automation tool:

Even in this 21st century, we were back w.r.t to automation. testing of the front end applications is being done manually in these days.   The manual testers use the code like java. But today we have many tools like Quick test pro (QTP), and Selenium IDE which were the most popularly used testers for most of the automated web applications.  This is used because many tools used the concept of record and playback approach.

The advantage of this approach is it captures the screen of the user and then simply playbacks those actions at the time of requirement. It means it just the same repetitive action for certain part of the code, but it does not work for all the time. If the cursor move changes at run-time the recorded action fails.  So we need an alternative to this.  One of the alternatives is using commands.   Have a glance below to know the commands of selenium automation tool.

Moreover, language (or) environment is another feature to perform validation of web applications to be tested. But this scripting introduces an additional level of complexity in the project, where the testers need to strive a lot regarding the new scripting language.

This selenium was initially started in 2004 as a JAVA script library that allows the interaction with a web page. Since it was based on java script, it is possible to run the library across multiple browsers. Hence  JavaScript becomes an essential part of selenium, Selenium Remote control (RC), and Selenium IDE. So the browsers that bases on JavaScript the library is not able to provide a comprehensive toolkit for testing.

With the intention of communicating with the browsers directly that overcomes some of the drawbacks of selenium google started working a project named web driver. One thing to be noted here is Selenium IDE is a part of selenium 1 and was supported by selenium. It is a Firefox plugin that provides an easy –to use interface for automated tests. This Selenium IDE has a recording feature which records the user actions as they are performed. The recorded actions can be used for later executions.

test suites usually combine the API with any of the programming languages. Using selenium API we can control the actions of the browser. One of the best news regarding selenium is that it supports multiple browsers. Some of them were Google Chrome, Mozilla Firefox, Opera, Safari, Microsoft Internet Explorer etc.
