## What it is
Moq is a Go code generation tool that creates mock structs from any Go interface for use in unit tests. It integrates with go generate and produces structs with function fields for each interface method, enabling per-test mock behavior.

## Use cases
- generate mocks for go interfaces
- reduce boilerplate when writing go unit tests
- mock dependencies in go tests via go generate
- verify interface method calls in tests
- create test doubles for interfaces

## When to choose
- you write Go unit tests with interface-based dependencies
- you want mocks generated automatically via go generate
- you prefer lightweight function-field mocks over reflection-based mocking frameworks

## When to avoid
- you need a full mocking framework with expectation DSLs
- your project is not written in Go
- you prefer hand-written fakes or stubs

## Facets
- artifact type: cli-tool
- maturity: active
- function: mocking, testing, cli, developer-tools
- domain: testing, developer-tools
- platform: go, cli, cross-platform
- tags: go-generate, codegen, unit-testing, interface-mocks, command-line
