ClassName Locator in Selenium Explained | Styling vs Automation in Software Testing(Beginner to Pro)

In this video, we continue our Selenium Automation Testing journey by diving deep into the ClassName locator — one of the most misunderstood locators in software testing.

So far, we’ve worked with ID, Name, and TagName locators, which focus on uniqueness and structure. In this session, we enter a different territory where frontend styling meets automation testing.

Classes in HTML are created for CSS styling and layout, not for automation. That’s exactly why using them blindly in Selenium often leads to flaky tests, NoSuchElementException, and unstable frameworks.

Using real HTML examples from our own practice page, this tutorial clearly explains:
What class names actually represent in HTML
The difference between single-class and multi-class elements
Why spaces completely break the className locator
How Selenium interprets By.className() internally
When it is safe to use className in automation testing
Why CSS selectors are the correct choice for multiple classes
Industry best practices followed in real software testing projects

This video is especially helpful for:
✔ Selenium beginners
✔ Manual testers moving into automation
✔ Software testing professionals
✔ Anyone confused about class-based locators

By the end of this tutorial, you’ll stop guessing with class locators and start using them logically, safely, and professionally — the way real automation testers do.
