"SELENIUM" - An Open Source Test Automation Tool for Web and Mobile

-
Selenium is one of the most popular open-source automated testing Tools available today.

Selenium automates web applications and mobile apps for testing purposes, but is certainly not limited to just that.

Introducing Selenium
Selenium is a free (open source) automated testing suite for web applications across different browsers and platforms. It is quite similar to HP Quick Test Pro (QTP now UFT) only that Selenium focuses on automating web-based applications. Testing done using Selenium tool is usually referred as Selenium Testing.

Selenium is not a single tool, instead it is a set of different tools each with a different approach to support test automation. Learning all the tools will give you different options for approaching different test automation problems. These tools when used together give many options for locating the UI elements and comparing expected test results against actual application behavior. The following  are the four tools that comprise the Selenium's Tools Suite:
  • Selenium IDE 
  • Selenium 1 (or Selenium RC) 
  • Selenium 2 (or Selenium WebDriver + RC) 
  • Selenium-Grid 


 Few Good things about the Selenium Automation Tools:
  1. Selenium is an open source tool i.e. Unlike the proprietary tools its available free of cost.
  2. This is the best tool available in the market for web application testing
  3. One of the selenium's key features is the support for executing one's tests on multiple browser platforms like Internet Explorer, Firefox, Google Chrome, Opera, Safari etc.
  4. Selenium allows you to control a browser from a language of your choice. You can choose any one of these Six languages to write automation scripts -> Java, C#, Ruby, Python, Perl and Php (In this Blog, we will be using Java)
  5. Selenium is available for Operating Systems such as Windows, Linux and Mac
  6. Selenium can be used for functional, compatibility, regression testings and User Acceptance Testing (Mainly used for Regression Testing).
Drawbacks of using Selenium Automation Tools:

1. Selenium is a browser based testing tool. It cant be used for automating the desktop applications. (i.e. It can be used only for automating the web based applications)

Explain public static void main in Java

Whether the class contains main method or not and whether main method is declared according to requirement or not these things won’t be checked by compiler. At Run time JVM is responsible to check these things. If JVM unable to find main method then we will get run time exception saying “No SuchMethodError: main” class Test { } Javac Test.java Java Test Runtime Exception: “No SuchMethodError: main” At Run time JVM always searches for the main method with the following prototype. public static void main (String[] args) public : public keyword is an access modifier which represents visibility, it means it is visible to all. To call by JVM from anywhere. This makes the main method public that means that we can call the method from outside the class. static : static is a keyword, if we declare any method as static, it is known as static method. The core advantage of static method is that there is no need to create object to invoke the static method. The main me

Reserve or Key Words in Java

Any programming language reserves some words to represent functionalities defined by that language. These words are called Reserved words. These words can't be used as names for Variables, Methods, Class or any other Identifier.

Automation can be defined as the technology by which a process or procedure is performed without human assistance . As per ISA , the dictionary defines automation as “the technique of making an apparatus, a process, or a system operate automatically.” We define automation as "the creation and application of technology to monitor and control the production and delivery of products and services.” For better reference watch the video below:- credits: Wiki, International Society of Automation (ISA), Youtube.
