A microservice application is a group of distributed programs that communicate over networks, occasionally interfacing with third-party services and databases. Microservices, by their networked nature, provide more points of failure than a traditional monolith. As a result of this, we need a different, broader approach to testing.
So, how do we test a microservice application? Does the testing pyramid still work? How do we test when third-party services are involved, and network disruptions are a possibility? We’ll attempt to answer all these questions in this post.
