 * @deprecated
 *
 * The Redux team does not recommend using this package for testing. Instead, check out our {@link https://redux.js.org/recipes/writing-tests testing docs} to learn more about testing Redux code.
 *
 * Testing with a mock store leads to potentially confusing behaviour, such as state not updating when actions are dispatched. Additionally, it's a lot less useful to assert on the actions dispatched rather than the observable state changes.
 *
 * You can test the entire combination of action creators, reducers, and selectors in a single test, for example:
 * ```js
 * it("should add a todo", () => {
 *   const store = makeStore(); // a user defined reusable store factory
 *
 *   store.dispatch(addTodo("Use Redux"));
 *
 *   expect(selectTodos(store.getState())).toEqual([{ text: "Use Redux", completed: false }]);
 * });
 * ```
 *
 * This avoids common pitfalls of testing each of these in isolation, such as mocked state shape becoming out of sync with the actual application.
 *
 * If you want to use `configureStore` without this visual deprecation warning, use the `legacy_configureStore` export instead.
 *
 * `import { legacy_configureStore as configureStore } from 'redux-mock-store';`
