What are the advantages and disadvantages of using the PageObject class compared to simple strings in automation tests?

The use of the PageObject class in test automation has the following advantages:

• Encapsulation of UI interaction logic: all actions and locators are concentrated in one place, which facilitates maintenance and modification of tests.
• Improved test readability: tests become more understandable as they use PageObject methods rather than raw selectors.
• Code reuse: the same PageObject can be used in different tests.
• Reduction of duplication: locators and methods are not duplicated across tests.

Disadvantages:

• Additional level of abstraction: requires time for development and maintenance of the PageObject.
• Complexity in small projects: for simple tests, using PageObject may be excessive.
• Risk of PageObject becoming outdated: if the UI changes frequently, the PageObject needs regular updates, otherwise tests will fail.

Unlike using simple strings (for example, locators directly in tests), PageObject provides a more structured and maintainable approach, especially useful in large projects with many tests.
