Contract Testing — quiz

A team has 6 services, each calling 3 others on average. A traditional integration test suite requires all services to run simultaneously. What is the primary advantage of consumer-driven contract testing in this scenario?

• Contract tests run faster because they skip all real network calls
• Each service can verify its contracts independently — the consumer generates a contract and the provider verifies it in isolation, so the full distributed system never needs to be running simultaneously
• Contract tests eliminate the need for unit tests within each service
• Contract tests automatically fix integration bugs as soon as they are detected
