  1. Best Testing Strategies in a Microservice Architecture

  2. Introduction Today, there is no dearth of information related to microservices on the web about what they are and how organizations are transforming their development architecture. However, there are very few articles that talk about the test strategies that must be followed while testing microservice architectural solutions and applications. This blog aims to help you provide the information. Before I continue to the Strategy, Test Areas, Test Types, etc., let us understand some of the definitions of microservices.  A microservice is a software development technique – variant of the Service OrientedArchitecture (SOA) style that structures an application as a collection of loosely coupled services. In a microservices architecture, services are fine-grained, and the protocols are lightweight. A microservice architecture builds software as suites of collaborating services. Microservices are often integrated using REST over HTTP. They connect with each other over networks and make use of “external” datastores.

  3. Microservice architecture, or simply microservices, is a distinctive method of developing software systems that try to focus on building single-function or single–purpose modules with well-defined interfaces and operations. This trend has grown popular in recent years as enterprises look to become more Agile and move towards a DevOps and continuous testing approach. Microservices can help create scalable, testable software that can be delivered very often; some of them as frequent as weekly and daily. Microservices architecture allows admins or users to load just the services that are required, which improves deploy times, especially when packaged in containers.Microservices provide changes only when and where they are needed. With a microservices architecture, the application monitors each functional component. Why do you need a special strategy to test microservices? You need a different strategy to test microservices as they follow a different architecture and have a lot of integrations with other microservices within one’s organization as well as from the outside world (3rd party integrations). Additionally, these require a high amount of collaboration among different teams/squads developing individual microservices. Moreover, they are single purpose services and are deployed independently & regularly. 

  4. The Strategies Before I discuss the various strategies, let us take a look at a self-explanatory diagram to understand the composition of microservices.  Different types of testing need to be performed at different layers of microservices. Let us look at them using an illustration of three microservices collaborating/working closely.
