Microservices - Testing MicroservicesWhich key advantage does Pact provide when implementing contract testing in a microservices architecture?AIt automatically generates API documentation for all microservicesBIt enables independent verification of service interactions without requiring full end-to-end testsCIt replaces the need for unit testing within each microserviceDIt enforces synchronous communication between microservicesCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand Pact's rolePact focuses on contract testing, which verifies interactions between services independently.Step 2: Compare with other testing typesUnlike end-to-end tests, Pact allows testing consumer-provider contracts without full system deployment.Final Answer:It enables independent verification of service interactions without requiring full end-to-end tests -> Option BQuick Check:Independent interaction verification [OK]Quick Trick: Pact tests contracts, not full system flows [OK]Common Mistakes:Confusing contract testing with API documentation generationAssuming Pact replaces unit testsThinking Pact enforces synchronous calls
