Thank you, your explanation was clear about how this works.
Do you mind telling me how to implement this tests using Spring Security with secured microservice with JWT for example.

Thanks for the simple explanation.
I didn't get the part on how the consumer was able to find the stub jar ? Did it just work coz it happened to be the same project ? How will it work in case of separate microservices ?
