Testing microservices can be a challenging job, as it is different from how we test applications that have been built using the traditional architectural style. Testing a .NET monolithic application is a bit easier than testing a microservice, which provides implementation independence and short delivery cycles.
Let's understand it in the context of our .NET monolithic application, where we didn't utilize continuous integration and deployment. It becomes more complex when testing is combined with continuous integration and deployment. For microservices, we need to understand the tests for every service and how these tests differ from each other. Also, note that automated testing doesn't mean that we will not perform any manual testing.
Here are a few things that make microservice testing a complex and challenging task...
