We will see what to have in component tests for an event-driven Microservice and understand what component testing is and how it's different from unit testing.
In an event-driven architecture, the microservices are often integrated using the pubsub (publisher-subscriber) model and connected to each other by messaging platforms such as Kafka, RabbitMQ, etc. Typically a microservice in event-driven architecture acts either as producer/consumer or both.
In this post, we will see what to have in component tests for an event-driven microservice. But before that, we will understand what component testing is and how it's different from unit testing.
Anything! A group of multiple units working together to accomplish a sub-journey of a longer user journey of the microservices lifecycle. Example:
A longer end-to-end journey:
Login > Compose a mail > Send it > Check the status in sent mail > Logout.
Different components of the longer journey:
Login > Compose a mail > Send a mail > Check the status in sent mail > Login > Logout > etc.
In a microservices architecture, a service itself can be considered as a component.
In this article, look at different ways to test microservices and how you can have a suitable testing strategy to begin with.
The shift towards microservices and modular applications makes testing more important and more challenging at the same time. Learn more here.
Learn how to test Microservices. Best Practices and Testing Strategies for Microservice test. It has only been a moment since the advantages of microservices surpassed those of monolithic systems. In practice, testing microservices can help us eliminate many problems by avoiding a domino effect.
Learn how to build your project with approaches to automating Microservices testing.Test automation of microservices helps create reliable testing, thereby reducing the time for test creation, analysis, and maintenance.
API endpoint when you send the get request to that URL it returns the JSON response. In this article, I am going to use postman assertions for all the examples since it is the most popular tool. But this article is not intended only for the postman tool.
