What is the purpose of "contract testing" (e.g., consumer-driven contract testing) in a microservices architecture?
Correct! Well done.
Incorrect.
The correct answer is A) A testing approach where consumers of a service define expectations ("contracts") about its API behavior, which providers can verify independently, catching breaking changes between services without full end-to-end tests across the system for every change
Correct Answer
A testing approach where consumers of a service define expectations ("contracts") about its API behavior, which providers can verify independently, catching breaking changes between services without full end-to-end tests across the system for every change
Contract testing allows teams to verify API compatibility between services in isolation, providing faster feedback than full end-to-end tests and reducing the tight coordination needed between teams deploying interdependent services.
