Selenium WebDriver Locators & Element Identification

Question 1

Which locator strategy is generally considered the most reliable for identifying web elements in Selenium WebDriver?

Accepted Answer

ID

Answer

The ID attribute is unique per page by HTML specification, making it the most stable and reliable locator when available.

Question 2

What method is used to find a single element by its CSS selector in Selenium WebDriver?

Accepted Answer

driver.findElement(By.cssSelector("..."))

Answer

The correct By class method for CSS selectors is `By.cssSelector()`, using the full compound name.

Question 3

Which By locator would you use to find an element with the HTML attribute `name="username"`?

Accepted Answer

By.name("username")

Answer

`By.name()` directly targets the HTML `name` attribute, making it the appropriate locator for this case.

Question 4

What does `driver.findElements()` return when no matching elements are found on the page?

Accepted Answer

An empty list

Answer

`findElements()` (plural) returns an empty `List<WebElement>` when nothing matches, avoiding exceptions.

Question 5

Which XPath expression correctly selects a button element whose exact text content is "Submit"?

Accepted Answer

//button[text()="Submit"]

Answer

The XPath `text()` function retrieves the text node of an element, and `=` performs an exact match.
