Best Practices and Testing Strategies for Microservice Testing.

It has only been a moment since the advantages of microservices surpassed those of monolithic systems, which has left little room for changes and innovation, thus far.

A monolithic application would be developed as a single unit. To make any iterations, an engineer would need to deploy an updated version of the server side application. Microservices, on the other hand, are developed with business-oriented APIs to encapsulate a core business capability. The principle of loose coupling helps eliminate or minimize dependencies between services and their consumers.

However, the microservices architecture has its own challenges, especially when it comes to keeping track of all updates going out simultaneously. One way to make sure you are not deploying a microservice with broken code, is to have a system in place for testing microservices — which is inherently different from testing a monolithic system.

Why do we test microservices?

First of all — For peace of mind. In practice, testing microservices can help us eliminate many problems by avoiding a domino effect.

The biggest issue in a distributed environment is that you have a lot of moving parts within the systems and subsystems. It’s constantly changing, and a lot of services are interacting with each other simultaneously.
