Round Earth Test Strategy

This article is very interesting in that it offers a new perspective on the importance of a front-end user perspective first type of testing scheme. It starts off by explaining to us the normal pyramid testing scheme and how at the tip of the pyramid is where the user perspective and UI is. This article is contrary to all of those other testing pyramids because, by how this article explains it, the top of the pyramid is just as, if not MORE important than the lower levels. Typically in a Test Automation Pyramid you have Unit or unit tests at the bottom (long base), then you have your service tests (integration, component, and api tests: middle slice), and finally at the top you have your user interface and ideally what the user sees. Knowing that, this article explains how the pyramid should actually be flipped upside-down, having the user perspective be of larger importance. You would still have your unit tests and integration on the bottom and middle, it just wouldn’t be as large. This is the point the article is trying to make, “Just as a triangle has more area in its lower part than its upper part, so you should make more automated tests on lower levels than higher levels.” This is not an argument; this is not reasoning. Nothing in the nature of a triangle tells us how it relates to technology problems. It’s simply a shape that matches an assertion that the authors wanted to make. It’s semiotics with weak semantics.” Pretty much, the article is saying that the shape of the triangle in which these schemes are based on don’t really carry that much weight into technological problems.

My reaction to this article is that I agree with what they are describing here. Similarly to the article, I also think that when you have a project, each layer above the next can often be a lot more complex than compared to the lower levels. This in turn can also even carry a higher risk. The model the author is talking about is the Round Earth model. The round Earth model states that you should think of technology as concentric spheres and that each layer can increase dramatically. This article made me open my eyes and made a lot more sense of how certain models don’t really understand what they even stand for.
