How to test Redux actions that update the Redux store state from a React component (e.g., clicking a hamburger icon toggling sidebar visibility).

AFFECTSRootCause

RTK Query manages its own cache in a separate reducer subtree, so directly using slice hooks/reducers from within the API slice isn’t the intended pattern. Without using RTK Query lifecycle matchers or dispatching additional actions, the historical store won’t be updated.

AFFECTSRootCause

Redux state is intended to be serializable (and may be blocked/stripped by Redux serializability expectations), while the Paho.Client instance is a complex class with internal runtime state and functions that cannot be reliably persisted in Redux.

AFFECTSRootCause

The issue is caused by missing/unsatisfied Redux DevTools setup in the browser (used via `composeWithDevTools`), leading to runtime failure in Stackblitz.

AFFECTSRootCause

redux-persist stores data along with a persist configuration version, and migrations must be keyed to those version numbers. Without properly versioning the persisted state and providing matching migration functions, redux-persist cannot correctly apply the transformation from the old structure to the new one.

AFFECTSRootCause

The store is being subscribed with a non-function value (passing the return value of ReactDOM.render/createRoot().render) to store.subscribe, which expects a listener callback function.

Dispatching an action causes a runtime TypeError: "listener2 is not a function" inside Redux's dispatch flow.

AFFECTSRootCause

The callback is being treated as an untyped function because `rootReducer` is defined as a plain object rather than being typed to match `configureStore`'s expected `middleware` option signature, so TypeScript cannot infer the parameter type.

REQUIRESSolution

Configure `persist` to persist only the desired state (e.g., via `partialize`) while keeping action functions in the non-persisted portion of the store. Alternatively, avoid wrapping each slice with its own `persist` and instead use a single store with `persist` applied appropriately.

FIXED_BYSolution

Configure `persist` to persist only the desired state (e.g., via `partialize`) while keeping action functions in the non-persisted portion of the store. Alternatively, avoid wrapping each slice with its own `persist` and instead use a single store with `persist` applied appropriately.
