Uses `go generate` to automatically create mock structs from Go interfaces, eliminating manual boilerplate and ensuring type safety, as shown in the example with the Service interface.

Records each method invocation with parameters and results in structs like QueryInvocation, enabling precise assertions about mock usage in tests without extra setup.

Allows defining custom behavior for interface methods via hook functions, supporting diverse test scenarios, such as conditional logic or error simulation in the example.

Integrates natively with Go's toolchain via `go generate` and standard testing practices, fitting smoothly into existing workflows without external dependencies.
