Most articles on Page Object Model are written by people who maintain twelve tests. This is one written by somebody who has lived inside a 2,400-test web automation suite for three years and watched it ossify, get rebuilt, and ossify again.I don’t think POM is wrong. I think the version of POM that gets taught — one class per page, methods that wrap WebElement clicks — falls apart somewhere around 300 tests. The version we run today still calls itself POM, and the page classes look like the original ones, but underneath there are three or four patterns layered on that nobody told me about when I started. This article is about those patterns.
