Selenium With Python


Selenium Automation Using Python Language


Selenium is a browser automation tool used to automate web applications. In this post we are going to learn how to use Selenium in python programming language.


Introduction to Selenium


Selenium automates websites. It’s like a robot that can go to any website, type anything and click on any links. But, unlike robots, Selenium is not restricted to only websites – it can even run scripts written in other languages (such as java, php etc.).

Selenium automation is the way to automate your work in the field of programming. Automation means that we can skip steps of the process to get better results at less time. Selenium is used to do different things like clicking on any link and getting data from websites. Also, it helps us in saving time and doing repetitive tasks over and over again.



What is Selenium WebDriver?


WebDriver is a way to automate your website/web application testing. There are many different programming languages used to build applications, including Java, C, Python, Ruby, etc. Each language has its own syntax; however, they all share certain similarities. They all use keywords, variables, data types, control structures, loops, functions, and so on. Because each language uses similar concepts, developers can easily switch between these languages when developing software. Learn more from Selenium Testing Course in  Vizag


Selenium WebDriver is a toolkit that is used to write test scripts using any programming language. Selenium WebDriver makes it easy to interact with a browser through programs written in other languages. In addition to being able to interact with a web browser, Selenium WebDriver provides functionality to execute JavaScript code in the context of a web page.


In a nutshell, this tool allows us to programmatically perform actions on our websites without having to manually code HTML, CSS, or Javascript. We can take advantage of built in features already present on websites like form validation and AJAX calls to create automated tests. It is a great solution for writing tests against sites that don't allow manual testing.


Why is Python useful for automation testing


Python was originally created at AT&T Labs in the early 1980s. Today, it’s used widely in science, engineering, finance, analytics, education, and a wide array of other fields where people need software that can deal with large data sets and complex tasks. There are several reasons why Python has become such a popular scripting language.


First, Python lends itself to writing clear code for both humans and machines. Its syntax is logical and easy to understand. Second, Python supports object-oriented programming (OOP), making it easier to develop reusable code modules. Third, its open-source design makes it easily modifiable by any programmers who want to enhance it. Because of this openness, Python has become an extremely active community with many contributors from around the world. 


Python has become a popular choice amongst developers looking to automate various tasks. In this article I'll explain how the use of Python can improve your day-to-day work and teach you some cool tricks that may help you become a better developer.


What can Python Selenium do?


Here is a list of things that python-selenium can do for you:


  • Automate web scraping
  • Scraping images
  • Scraping videos
  • Download google docs
  • Upload files to dropbox


It can even scrape RSS feeds and pull out the data from them. So, whether you want to find some information about something or you just want to automate a few tasks that normally have to be done manually, Python-Selenium can definitely help!


How do I add Selenium automation to Python?


1.  Run aAnconda install selenium

2. Open up a terminal and run python -m pip install selenium

3. Add the following code inside your test file: from selenium import webdriver

4. Finally, run your tests!


Which framework is best for Python Selenium?


Frameworks are libraries that provide structure to program code. They make programming easier by giving developers common features they can use across multiple applications. There are several popular frameworks out there and each has its own pros and cons. Here we discuss how to choose between them depending on your needs.


The following frameworks are used in web application testing. 


1.Selenium 2 WebDriver (formerly known as WebDriver)

2.Puppeteer (Google Chrome Driver)





How Python is useful for testers?


  • Python scripts are great at automating repetitive tasks, especially if these tasks require access to the operating system or the Internet. In addition, many of the tools that can automate testing have been built using Python language. You can find some excellent libraries that make developing tests much easier, like Selenium and Nose.


  •   The python programming language allows you to manipulate data easily. Therefore, you can use a script to read files from your local machine and write them into a database, or you can even directly interact with databases through SQL queries. This means that you don’t need any additional software to run those tests.


  • Many developers who are not familiar with debugging techniques often find themselves stuck while trying to fix a bug in their code. However, this is where Python comes in handy. Because of its unique features, including dynamic typing and interactive interpreter, developers can debug their programs easily.
