Testing / Selenium Interview questions
What is the difference between findElement and findElements in Selenium?
Both search the DOM using a By locator, but they differ in what they return and how they fail.
| findElement | findElements |
| Returns a single WebElement | Returns a List<WebElement> |
| Throws NoSuchElementException if nothing matches | Returns an empty list if nothing matches |
| Use when you expect exactly one match | Use to check existence or iterate multiple matches |
Because findElements never throws for zero matches, it's the safer choice when you specifically need to check whether something exists without wrapping a try/catch around a potential NoSuchElementException - checking list.size() == 0 is a common existence-check pattern for exactly this reason.
Performance-wise the two are otherwise identical - both perform the same DOM search internally, so choosing between them should come down to whether the code expects exactly one match or needs to tolerate zero or many.
If no element matches, findElement will:
A common existence-check pattern uses findElements because it:
