In today’s world, most of the applications are connected with the web-based applications that can be accessed with the different web browsers. For that substance, selenium is an ultimate tool for testing various web applications. That is able to record and play the simplest web application scripts. It has a beneficial tool for working in the testing framework for the web applications. It is the automated testing application that is supporting with the multiple programming languages such as selenium java, C#, ruby and python.

Java is the basic knowledge to learn about the basic concepts of the automation testing process of selenium. Selenium web driver with java can provide a test domain to the specific language and write tests in a number of popular programming languages such as groovy, PHP, scala etc. it is able to run against most model web browsers.

What is selenium?

•         Multi-platform support
•         Multi-browser support
•         Supports cross-browser testing
•         Multiple programming language support
•         Support test mobile web applications
•        Open-source

Classification of selenium

Selenium is the testing tool that must be classified into four different tools such as:

⮚      Selenium RC- It is an important component in the selenium test suite. This testing software enables with any programming language to automate UI tests for web applications against another website

⮚      Selenium IDE – It is easy to use the tool from the test suite. And it is developing the test cases for their web applications

⮚      Selenium grid – This tool is specialized to running in a multiple test process across the different browsers, operating system and machines

⮚      Selenium web driver – It is the collection of open-source API that can be used to automate the testing of a web application

Is selenium easy to learn?

It is one of the most common questions which is raised in everyone’s mind. Yes, it is! Selenium is a wonderful language and more easy to learn. It requires a good disciple and understanding of the road map to learn it fast. It is an open-source platform so anyone can use it to test their website or web application and make a common understanding, learn and practice with the web driver. It has many libraries and frameworks; selenium web driver with python is the most specialized language than C#. It is more useful for students to learn with the best machine learning and artificial intelligence libraries.

Advantages of web driver

✔      Supporting to the many programming languages, operating system and web browsers

✔      Overcoming the limitations of the selenium like field upload and download barriers

✔      It is better than the API process and simpler than RC

✔      It support for the batch testing, cross-browser testing and data-driven testing processes

Common elements of selenium web driver

 By ID

Syntax: driver.findElement (By.id (“element id”))

By class

Syntax: driver.findElement (By.className (“element id”))

By name

Syntax: driver.findElement (By.name (“element”))

By TAGNAME

Syntax: driver.findElement (By.tagName (‘Element html tag name’))

By CSS Selector

Syntax: driver.findElement (By.cssSelector (“css selector”))

These are the basic elements for the selenium automation test tool. As a beginner, you need to learn all the other methods and web browsers commands that can be used to perform operations on the elements.

Features of selenium

Speed control – It is helpful to control the speed of the test cases

Run all – It allows an execution of the entire test suite

Run – It can able to run the currently selected test

Pause/Resume – It allows the users to pause and resume a particular test case

Step – It helps to step into each specific command in the test script

Selenium as a career

Selenium can make functional testing easier and more convenient for the clients to receive ROI much faster. It has been identified as a powerful automation tool for making an effective delivery. A lot of companies are offering huge opportunities for the best selenium tester.

Selenium web driver professionals should have the popular job roles such as

•         Automation test lead
•         Senior test engineer
•         Quality engineer
•         Selenium automation analyst
•        QA engineer

These selenium test automation tools are linked with various firms like Google, Mozilla, LinkedIn, IBM etc. it is the best guide to the beginners who are planning to become a selenium programmer. Make use of it and keep enjoying it.
