Every day our surroundings test our boundaries. We don’t always manage to maintain them effectively either. But more on that another time. Recent years our day-by-day work with apps in our PHP world oscillates around hexagonal architecture, modular monoliths and, not so infrequently, distributed apps proudly named microservices. Although they are often several orders of magnitude over the micro level. At the same time, I have the impression that after a few years of talking about testing and developing new tools to support them, we lose some focus on it for the sake of all those architectural topics.

However, in our ecosystem, we have awareness of different test classes and tools that work with them. During this talk we will take a look at those classes, tools and some examples. We will also try to place them somewhere over this so trendy hexagons and we will try to figure out how and where to use them in different parts of our applications.
