When you hear the word Selenium, what comes to your mind first?
A chemical element from the periodic table, or one of the most popular automation tools for web testing?
As a Tester Friend, I like to know both.
Selenium as a Chemical Element
In chemistry, Selenium has the symbol Se and the atomic number 34. It is used in several industries, especially:
- Glass production
- Manufacturing of certain copper and metal products
Selenium also plays a role in health and medical science. It is considered an essential trace element for humans, and selenium levels in the body can be measured through blood tests. Research has linked selenium to support in managing serious or chronic conditions such as cancer, diabetes, HIV/AIDS and tuberculosis.
So yes, Selenium is more than just a word from our automation world – it is also a real chemical element with practical uses in industry and medicine.
Selenium as an Automation Tool
Now, let’s come back to what most testers love to talk about: Selenium – the automation tool.
Selenium is a powerful open‑source framework used to automate web applications. It allows testers and developers to simulate user actions in the browser, run regression tests quickly and support continuous integration pipelines.
The Selenium family includes different components:
- Selenium IDE – A browser extension for quick recording and playback of tests.
- Selenium RC – An older component that allowed writing automated tests in different languages.
- Selenium WebDriver – The modern and widely used API for browser automation, supporting multiple languages and browsers.
With Selenium, you can:
Automate repetitive test cases
Run tests across different browsers and platforms
Integrate with test frameworks and CI/CD tools
If you are thirsty to learn automation, Selenium is a great place to start.
