Testing / Selenium Interview questions

What are the supported programming languages in Selenium WebDriver?

Selenium WebDriver provides official client bindings for four languages, all built against the same underlying W3C WebDriver protocol.

Java - historically the most common, often paired with TestNG or JUnit.
Python - the selenium PyPI package, commonly paired with pytest.
C# - used with NUnit or MSTest in .NET projects.
JavaScript/Node.js - the selenium-webdriver npm package.

Because every binding talks to the same driver executables over the same protocol, the underlying capabilities (locators, waits, actions) are conceptually identical across languages - switching languages mostly changes syntax and the test framework you pair it with, not what Selenium itself can do.
