In here single applications are developed to work together as a suite of small services while everyone runs individually and communicates with HTTP resource API. These services can be written in different programming languages.
Independently deployable by a fully automated machinery.
Using different data storage technologies.
Using different programming languages/technologies/DB.
Running in its process.
Communicating with a lightweight mechanism.
How to test Microservices
Component Tests: Typically, an application would be composed of a number of Microservices; so in order to test in isolation we need to mock the other Microservices.
End-To-End Tests: To make sure everything ties together. End-to-end tests verify that a system meets external requirements and achieves its goals, testing the entire system.
Integration Tests: An integration test verifies the communication paths and interactions between components to detect interface defects.
Contract Tests: Contract tests verify interactions at the boundary of an external service asserting that it meets the contract expected by a consuming service.
General Attention Microservices
APIs connects Microservices and traditional systems. It makes it easier to build and manage Microservices. With an API strategy, companies can expose the functionality of Microservices as products, which can lead to both internal and external business value.
Being standardized and cost effective, it allows organizations to quickly plug and unplug Microservices as business needs require. APIs grant the benefits of standardized mechanisms for traffic management and monitoring, logging, auditing, and security in a standardized way throughout the enterprise while retaining the agility required by the business.
