findElementfindElementsReturns the first matching web element if multiple web elements are discovered by the locatorReturns a list of multiple matching web elements
Why ID is preferred than XPath?
This is because : ID is considered as unique key so there cannot be more than 1 elements for same ID while Xpath is created using relative path/position of elements, so there can be cases when we can get 2 or more elements for same Xpath.

What is difference between POM and page factory?
S.No.POMPageFactory4.’By’ annotation is used to define page objects.It uses annotation ‘FindBy’ to describe page objects.
Why TestNG is used in the testing framework?
TestNG makes automated tests more structured, readable, maintainable and user-friendly. It provides powerful features and reporting. Its high-end annotations like dataprovider, makes it easier to scale up, as you perform cross browser testing across multiple devices, browsers, and their versions.
Which is faster XPath or CSS?
Xpath is slower in terms of performance and speed. Css has better performance and speed than xpath. Xpath allows identification with the help of visible text appearing on screen with the help of text() function.
Which locator is preferable in selenium?
