## What it is
mockery is a CLI tool that auto-generates mock implementations for Go interfaces using the stretchr/testify/mock package. It eliminates the boilerplate of hand-writing mocks so developers can focus on writing tests.

## Use cases
- generate mocks for Go interfaces
- remove boilerplate when writing Go unit tests
- create testify-based mocks automatically
- mock dependencies for Go testing
- replace hand-written mock implementations
- set up mocking in a Go project

## When to choose
- you write Go code and use testify/mock for testing
- you have many interfaces and want mocks generated consistently
- you want a maintained, widely-adopted mock generator (7k+ stars)

## When to avoid
- you use a different mocking style like gomock or hand-rolled stubs
- your project is not in Go
- you prefer runtime mocking over generated code

## Facets
- artifact type: cli-tool
- maturity: active
- function: mocking, testing, cli
- domain: testing, developer-tools
- platform: go, cli, cross-platform
- tags: mock-generator, testify, golang-interfaces, boilerplate-removal, code-generation, command-line
