The locator is a command. that tells Selenium IDE which GUI elements. its needs to operate on. Identification of correct GUI elements is to creating an automation script. The identification of GUI elements is more difficult than it sounds. Sometimes working with incorrect GUI elements or no elements at all. Hence, Selenium provides many Locators for locating a GUI element.

The Testing different applications Application under Test. we need to identify the object made of. it is Web Application or Desktop Application.


  •   Button


  •   Text Box


  •   Link


  •   Drop Down

Here XPath and CSS are the most used locators.


It is very easy to identify the object of the application. Which built on Firefox but same on the other way. if that application made on IE browser then it is pretty difficult to identify the object.


There are different tools available to identify the objects on different browsers. like Firefox/Chrome/IE etc.

  •   XPath Checker


  •   Fire Finder


If we are using Selenium IDE there are different ways to identifying the objects. By default, Selenium identifies the object using ‘ID’ or ‘Name’.


The order of identifying the object in Selenium IDE is following:
