Page Object Model Purpose | Dataford Interview Questions

What is the Page Object Model (POM) and why is it used in test automation?

Implement resolve_test_steps(page_objects, steps) to demonstrate the separation between logical test actions and UI selectors. Each page object contains selectors and may inherit elements from a parent page.

Input: A map of page names to page definitions, and an ordered array of actions containing page, element, action, and an optional value. Supported actions are click, type, and select.

Output: Return one result per action, resolving inherited selectors. Return a successful result with the selector, or an error result for an unknown page, unknown element, or unsupported action.

Constraints: page inheritance is acyclic; child elements override parent elements.

Constraints

1 <= number of page objects <= 1000
1 <= number of test steps <= 10000
Each page definition contains an optional parent and an element-to-selector map
Page inheritance is acyclic
Supported actions are click, type, and select
Child elements override selectors inherited from a parent
