When you write tests against a web page, you need to refer to elements within that web page in order to click links and determine what's displayed. However, if you write tests that manipulate the HTML elements directly your tests will be brittle to changes in the UI. A page object wraps an HTML page, or fragment, with an application-specific API, allowing you to manipulate page elements without digging around in the HTML.
When I took my first real dev job in the late 90s, it was not common for developers to write their own automated tests. Instead, large companies depended on teams of testers, who tested manually, or were experts in complex (and expensive) automation software. Small companies were more likely to depend on code review, months of “integration” after the “development,”…or most commonly: pure hope.
I think that's the direction we're heading. Less emphasis on unit tests, because we're no longer doing test-first as a design practice, and more emphasis on, yes, slow, system tests. (Which btw do not need to be so slow any more, thanks to advances in parallelization and cloud runner infrastructure).
I hate "X upstart vs. Y incumbent" technology posts. They're reductive, provocative, and they cherry pick contexts favorable to the Shiny New Thing™ over the older, broader standard-bearer.
Eliminate risk and deliver value using feature management in your development cycles. Deploy code when you want. Release features when you're ready. Control your users' experience.

In previous posts and presentations I talked about how to test, and when to test. To conclude this series of I’m going to ask the question, why test at all?

Page Object Model is a design pattern which has become popular in test automation for enhancing test maintenance and reducing code duplication. A page object is an object-oriented class that serves as an interface to a page of your AUT.
As it states in the Bunny Theory of Code, the code tends to multiply in a quick way. And even with such great tools as Vue and Vuex it’s easy to make a mistake that might grow later all over the project. Here I will talk about Vuex and its getters, and how they might be used in a wrong way. And while dealing with that, I tried to figure out what Vuex getters are good for and how they work under the hood.
