示例1: return
return (state: S, action: any) => {
if (action.type === STATE_LOADING_DONE) {
return appReducer(action.payload, action)
}
return appReducer(state, action)
}示例2: deepFreeze
export const reducerTester = <State>(): Given<State> => {
let reducerUnderTest: Reducer<State, ActionOf<any>> = null;
let resultingState: State = null;
let initialState: State = null;
const givenReducer = (reducer: Reducer<State, ActionOf<any>>, state: State): When<State> => {
reducerUnderTest = reducer;
initialState = { ...state };
initialState = deepFreeze(initialState);
return instance;
};
const whenActionIsDispatched = (action: ActionOf<any>): Then<State> => {
resultingState = reducerUnderTest(initialState, action);
return instance;
};
const thenStateShouldEqual = (state: State): Then<State> => {
expect(state).toEqual(resultingState);
return instance;
};
const instance: ReducerTester<State> = { thenStateShouldEqual, givenReducer, whenActionIsDispatched };
return instance;
