About the test

The React and Redux Toolkit online test uses coding tasks to assess the skills required to build front-end applications with React and manage the application’s state with Redux toolkit.

The assessment involves solving work sample tasks such as:

  • Handling React lifecycle events.
  • Conditionally rendering components based on user inputs.
  • Creating a store, reducers, and dispatching actions in Redux Toolkit.

A good React developer using Redux Toolkit needs a solid understanding of both libraries to build and maintain complex front-end applications.

Thunk

A web application for a meteorologist's dashboard uses a Redux store to manage temperature data. The Redux store is configured with the Redux toolkit where the latest temperature data is fetched using the Redux thunk function.

Below is the code for the store's configuration:

const weatherURL = "http://example.com/temperaturejson";

const fetchTemperature = createAsyncThunk(
  "weather/fetchTemperature",
  async (arg, thunkAPI) => {
    const response = await fetch(weatherURL);
    return response.json();
  }
);

const temperatureSlice = createSlice({
  name: "temperature",
  initialState: { temperature: 0 },
  reducers: {},
  extraReducers: (builder) => {
    builder.addCase(fetchTemperature.fulfilled, (state, action) => {
      state.temperature = action.payload.temperature;
    });
    builder.addCase(fetchTemperature.pending, (state, action) => {
      state.temperature = "loading";
    });
    builder.addCase(fetchTemperature.rejected, (state, action) => {
      console.log(action);
      state.temperature = "unavailable";
    });
  },
});

const weatherStore = configureStore({ reducer: temperatureSlice.reducer });

What is true about the behavior of weatherStore?

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
