To structure a Go backend microservice, use a layered Handler → Service → Repository architecture. This pattern enforces consistent error handling and context propagation, making the application robust and maintainable.

The best way to mock database queries in Go testing is using sqlmock. It allows you to assert parameterized queries and safe transaction management within table-driven tests without needing a real database connection.

Implement observability and tracing in a Go microservice through context propagation. Apply structured logging, tracing, and metrics patterns alongside HTTP middleware like RequestID to monitor service behavior.

Yes, you can use mockery v3 for dependency mocking in Golang. It integrates seamlessly with table-driven tests to generate mocks for your service and repository interfaces, ensuring comprehensive test coverage.

Go backend APIs should use standard HTTP middleware patterns for RequestID, Logging, Recovery, and Authentication. These templates handle cross-cutting concerns safely before requests reach your core service logic.

Yes, this approach supports safe transaction management in Golang. It provides templates demonstrating parameterized queries and secure database interactions to ensure your repository layer handles data safely.
