## What it is
Mocha is a Ruby library for mocking and stubbing in unit tests, providing a unified syntax for full and partial mocking of test doubles. It integrates with Minitest, Test::Unit, RSpec, and Cucumber.

## Use cases
- stub methods on Ruby objects in unit tests
- create mock objects with expectations for unit testing
- mock with Minitest
- use mocha adapter with RSpec
- partially mock existing Ruby objects
- verify method invocation counts in tests

## When to choose
- you need mocks or stubs in Ruby tests with Minitest, Test::Unit, or RSpec
- you want a simple, readable mocking syntax
- you need partial mocking of real objects

## When to avoid
- you need test spies or fake objects, which Mocha deliberately does not support
- you are not writing Ruby
- you prefer RSpec's built-in double/expect syntax

## Facets
- artifact type: library
- maturity: stable
- function: testing, mocking
- domain: testing, developer-tools
- platform: ruby
- tags: test-double, stubbing, minitest, test-unit, rspec
