> The trouble is, you're often left unwinding a half-dozen layers of abstraction, and in many cases experiencing what looks like some sort of quantum code interaction, where changes in one part of the codebase seem to impact completely unrelated bits of code which now fail tests. This perfectly sums up all of the microservice apps that I’ve had the pleasure of working on, with the exception of issues being caught by tests. Typically you get either silent production data corruption or a seemingly unrelated error in the UI x weeks down the line.
