Being completely independent testing out services with dependencies is extremely challenging. As a microservice gets introduced into the ecosystem, proper governance and testing are needed, otherwise it will be a single point of failure for the system. Several levels of testing are needed for any microservice. It should start from whether the service is able to access cross-cutting concerns (cache, security, database, logs) or not. The functionality of the service should be tested, followed by testing of the protocol through which it is going to communicate. Next is collaborative testing of the microservice with other services. After that is the scalability testing followed by fail-safe testing.
