How long do your acceptance tests take to run? 10 minutes? An hour? A day? Do your acceptance tests sometimes pass, sometimes fail depending on the phase of the moon? Whenever an acceptance test fails, do you sometimes spend hours or days to diagnose the cause of failure because the test touches so many layers? Come and join Aslak to discover the right techniques for designing and building a testable software architecture!
A software system that wasn't designed with testability in mind makes it hard to get rid of those problems. There is a better way - acceptance tests that run in seconds, with predictable behaviour that are easy to diagnose when they fail.
During this talk you will learn the basic techniques for designing and building a testable software architecture, using techniques like the ports and adapters patter, and contract tests. You'll learn how these techniques can be applied with DDD, and how it fits in with different bounded contexts, micro services and distributed systems.
