## What it is
A mock Redux store for testing async action creators and middleware by recording dispatched actions. The Redux team now deprecates it in favor of testing with a real store.

## Use cases
- test redux async action creators
- assert dispatched actions in unit tests
- test redux middleware in isolation
- mock redux store in jest tests
- verify action payloads without reducers

## When to choose
- you maintain a legacy codebase already using it
- you only need to assert on dispatched actions, not state changes

## When to avoid
- starting a new project - the Redux team recommends testing with a real store
- you need tests that combine actions, reducers, and selectors
- you want state to update when actions are dispatched

## Facets
- artifact type: library
- maturity: maintenance
- function: testing, mocking, state-management
- domain: frontend, testing, web-development
- platform: -
- tags: redux, unit-testing, mock-store, deprecated, action-creators, middleware-testing, nodejs, javascript
