Testing microservices is a bit different from applications built on the traditional architectural style. In a .NET monolithic application, testing is a bit easier as compared to microservices, and it provides implementation independence and short delivery cycles. Microservices face challenges while performing the testing. With the help of the testing pyramid concept, we can strategize how to go with testing. Referring to the testing pyramid, we can easily see that unit tests provide the facility to test a small function of a class and are less time-consuming. On the other hand, the top layer of the testing pyramid enters a large scope with system or end-to-end testing, and these tests are time taking and much expensive. Consumer-driven contracts are a very useful way to test microservices. Pact-net is an open source tool meant for this. Finally, we went through the actual test implementation.
In the next chapter, we will see how to deploy a microservice application. We will discuss...
