Microservices Testing Fundamentals — quiz

A team building a microservices system has 1,000 unit tests, 50 integration tests, and 5 end-to-end tests. They keep seeing failures in production where services interact incorrectly. Which adjustment to the testing pyramid is most appropriate for microservices?

• Add more unit tests to achieve higher code coverage
• Increase the proportion of integration and contract tests — the interaction seams between services are where microservice bugs live, making them proportionally more critical than in a monolith
• Replace all unit tests with end-to-end tests for full coverage
• Remove integration tests as they are too slow for microservices pipelines
