Selenium is a powerful tool for controlling web browsers through programs and performing browser automation. It is functional for all browsers, works on all major OS and its scripts are written in various languages i.e Python , Java , C# , etc, we will be working with Python. Selenium Tutorial covers all topics such as - WebDriver, WebElement, Unit Testing with selenium. This Python Selenium Tutorial covers Selenium from basics to advanced and professional uses.

Pre-requisite to Learn Selenium Python Tutorial

  • B asic Knowledge of Python: Before diving into Selenium, you should be comfortable with Python basics.
  • Understanding of Web Technologies: Familiarity with HTML, CSS, and JavaScript is crucial because Selenium interacts with webpages by manipulating these elements.
  • Basic Programming Concepts: Concepts like variables, data types, control structures (if-else, loops), functions, and error handling are essential.

Why learn Selenium Python ?

  • Open Source and Portable - Selenium is an open source and portable Web testing Framework.
  • Combination of tool and DSL – Selenium is combination of tools and DSL (Domain Specific Language) in order to carry out various types of tests.
  • Easier to understand and implement - Selenium commands are categorized in terms of different classes which make it easier to understand and implement.
  • Less burden and stress for testers – As mentioned above, the amount of time required to do testing repeated test scenarios on each and every new build is reduced to zero, almost. Hence, the burden of tester gets reduced.
  • Cost reduction for the Business Clients – The Business needs to pay the testers their salary, which is saved using automation testing tool. The automation not only saves time but gets cost benefits too, to the business.

Learning Selenium with Python opens up many possibilities for efficient and effective web application testing, particularly when paired with popular cloud testing platforms like LambdaTest.

LambdaTest is an AI-powered test orchestration and execution platform that lets developers and testers perform Selenium Python testing at scale on a remote test lab of 3000+ real desktop browsers and operating systems. With Selenium Python, you can write robust test scripts to automate the testing of web applications, ensuring their functionality across different browsers and platforms. Developers and testers can even run tests in parallel on multiple combinations, helping them to ship quality builds at light speed.

Selenium WebDriver

Selenium Webdriver is the parent of all methods and classes used in Selenium Python. It is the driving force of Selenium that allows us to perform various operations on multiple elements on a webpage. Driver has various methods and attributes one can use to automate testing in Selenium Python. To check how to use webdriver, visit -

title Returns the title of the current page.

Selenium WebElement

An element can be a tag, property, or anything, it is an instance of class

selenium.webdriver.remote.webelement.WebElement

. After you find an element on screen using selenium, you might want to click it or find sub-elements, etc. Selenium provides methods around this WebElement of Selenium. To checkout how to use element object in selenium, visit -
