Introduction to Locators
Definition of Locators: Locators are attributes used to identify elements on an HTML page, such as input fields, checkboxes, links, and buttons.
Purpose of Locators: Essential for interacting with elements during automated testing, enabling actions like typing text or clicking buttons.
Types of Locators
ID: The most preferred method for locating elements due to its uniqueness.
Name: A common attribute used to identify elements.
Class Name: Used to target elements based on their CSS class.
Link Text: Targets hyperlinks by their visible text.
Partial Link Text: Matches part of the text of a hyperlink.
Tag Name: Locates elements based on their HTML tag (e.g., <button>, <input>).
CSS Selectors: Flexible and efficient for complex queries.
XPath: Least preferred but frequently used in real-world scenarios due to its versatility in identifying elements, especially in complex structures.
Hierarchy and Preference of Locators
Preferred Order: ID > Name > Class Name > Link Text > Partial Link Text > Tag Name > CSS > XPath.
XPath, while powerful, is typically a last resort due to performance considerations.
