In this Selenium Python tutorial for Beginners, you will learn the basics of how to install WebDriver, run test scripts, and automate browsers, etc.
Let’s start to get the most out of this Selenium WebDriver Python tutorial!
We live in a digital world where almost every company provides its services to customers online through websites, mobile applications, software packages, and so on. As time evolves, more and more companies have started to run their business online. Automation testing is the key to keep the success of such companies rolling by and to make their products and services show consistent results and offer a good user experience. Automation testing aids them to address any underlying issues of the UI/UX design, compatibility, performance, security issues, and website functionality. Let’s start this blog by understanding why we need to learn Selenium and what Selenium Python is.
Every tool has something unique to offer. Selecting the right tool comes down to understanding what an individual or a team is trying to accomplish. So, when would you choose Selenium?
For automating web applications, Selenium is the most popular and demanding tool than other testing tools. With that said, the below points will give you a clear idea of why Selenium takes first place in the world of web automation.
Selenium is a great framework that automates the testing of web applications and tests their flow from start to end. It works only with web applications/browsers. It does not support the testing of desktop applications/mobile applications. Due to its seamless nature, it is used for testing by bigwigs, including Google, Netflix, Fitbit, etc.
Nothing can beat the price tag. Selenium is so cheap that you will be able to finish this entire Selenium Python tutorial without spending much.
Selenium is an open-source software (OSS), which means that you get not only the product but the whole community. It has a lot of Selenium Developers willing to help someone who is in need. In the community, you will also see people sharing workarounds for the difficult problems they ran into.
Selenium is incredibly flexible in that it can run on most OS/browsers. It can also test iOS and Android browsers.
Here are the reasons:
The Selenium suite consists of four components. They are:
Selenium IDE (integrated development environment) is based on ‘playback and record testing.’ Here, the user does not have to write test scripts manually. Instead, the IDE does the following:
It records user interactions with the web browser to create Selenium IDE scripts.
It re-runs the recorded scripts n number of times to check for the stability and success rate.
The new Selenium IDE is available as both Firefox and Chrome extensions.
Selenium RC is used to design and automate UI tests for web applications. It enables a tester or a developer to write test scripts in any programming language. RC does not interact with the browser directly. It has a server that acts as an HTTP proxy to control the browser remotely.
This limitation gave birth to Selenium WebDriver, which is the successor of Selenium RC.
Selenium WebDriver is an API and protocol that supports the automation of all the major browsers in the market. Its aim is to emulate a real user’s interaction with the browser as closely as possible. It is faster and efficient than RC because it makes direct calls to the browser. It enables different browser backends to be used directly to gain cross-browser and cross-platform automation. It also supports languages such as C#, Java, Perl, PHP, Python, and Ruby.
Selenium Grid is very flexible and allows us to run tests in parallel on multiple machines. It acts as a central point to manage different browser versions and browser configurations, instead of working on each individual test. The main functionality of Selenium Grid is to run tests in parallel and to perform cross-platform testing.
