Describe your experience with automatic code generation in projects.

In Go projects, I used automatic code generation to reduce boilerplate and improve reliability. For example, generating code for serializing/deserializing structures to JSON or creating mocks during testing.

One common tool is go generate, which allows running code generators based on special comments in the source code.

Example of usage:

//go:generate mockgen -source=service.go -destination=mock_service.go -package=service

This enables automatic creation of mocks for interfaces, making unit testing easier.

I also used code generation for creating boilerplate code, such as CRUD operations with databases, using templates and tools like stringer or custom generators in Go.

Automatic generation helps avoid copy-paste errors, speeds up development, and maintains code consistency.
