Testing microservices (Work in progress)

Developing microservices without automated testing is self-defeating AND risky.

Chapters 9 and 10 of my book describe how to write automated tests for microservices-based applications.

Oracle Code One 2019 talk: Descending the test pyramid

My Oracle Code One 2019 talk is a good overview of how to test microservices.


The primary goal of the microservice architecture is to enable the rapid, reliable delivery of software using DevOps. One of the pillars of DevOPs is automated testing. Yet many organizations attempt to adopt microservices while still doing manual testing. What’s more, the microservice architecture has its own distinctive automated testing challenges. In this presentation, I describe how to descend the test pyramid and replace slow, brittle end-to-end tests with faster, more reliable tests for individual services. You will learn how to write tests that ensure service APIs evolve while preserving backwards compatibility. I describe how by running these tests in a deployment pipeline you will fully benefit from microservices.
