This video tutorial covers the use of locators in Selenium for web automation. It explains how to use different locators like ID, name, Xpath, and CSS to interact with web elements. The tutorial also demonstrates how to construct and validate CSS selectors using developer tools, highlighting the importance of choosing unique attributes for effective automation.

What method is used in Selenium to select a checkbox by its ID?

• findElementByName

• findElementByClass

• findElementByID

• findElementByXPath

What is the role of the 'sendKeys' method in Selenium?

• To click on elements

• To enter text into input fields

• To close the browser

• To refresh the page

Why is it important to understand HTML properties when using Selenium?

• To write JavaScript code

• To create CSS styles

• To choose the correct locator

• To design web pages

Which locator would you use if an element has a unique class attribute?

• ID

• Name

• Class

• XPath

Which Selenium locators are independent of developer-defined properties?

• ID and Name

• Class and Tag

• XPath and CSS

• Type and Value

Why might XPath and CSS be preferred over other locators?

• They are easier to write

• They are faster

• They are independent of developer-defined attributes

• They are more secure

What is the basic syntax for constructing a CSS selector?

• Attribute:Value

• TagName[Attribute=Value]

• TagName:Value

• Attribute=TagName

Why is it important to select unique attributes when constructing CSS selectors?

• To avoid browser errors

• To ensure the selector is unique

• To speed up the page load

• To reduce code complexity

How can you verify if a CSS selector is correct using browser tools?

• By checking the page source

• By using the console in developer tools

• By refreshing the browser

• By inspecting the network tab

What happens if a CSS selector matches multiple elements on a page?

• Selenium will not select any element

• Selenium will throw an error

• Selenium will select the last element

• Selenium will select the first element
