Quick Answer
Testing microservices: Unit tests for individual service logic. Integration tests for the service with its real DB and dependencies. Contract tests (Pact) verify the service honors its API contract with consumers. End-to-end tests for critical user journeys (limited, slow, expensive). Consumer-driven contract tests catch breaking API changes before deployment.
Answer
Unit tests validate isolated components. Integration tests ensure communication between services. Contract tests validate API compatibility. End-to-end tests verify complete workflows across microservices.
