as mentioned in the title I'm trying to set up some test for <Search />
component, in particular I want to test the useState
hooks. After mocking the Redux store and creating a shallow wrapper I tried to simulate an input from the child component DisplaySearchBar
but apparently I cannot even mamage to select it. That's the error I get:
Method “props” is meant to be run on 1 node. 0 found instead.
Here's Search.js
import React, { useState } from 'react';
import { connect } from 'react-redux';
import PropTypes from 'prop-types';
import { handleScriptLoad } from '../../../helpers/Autocomplete';
import { getRestaurants, setAlert } from '../../../actions/restaurantAction';
import DisplaySearchBar from '../../layout/DisplaySearchBar/DisplaySearchBar';
import styles from './Search.module.scss';
const Search = ({ getRestaurants, setAlert }) => {
const [where, setWhere] = useState('');
const [what, setWhat] = useState('');
const [sortBy, setSortBy] = useState('rating');
const sortByOptions = {
'Highest Rated': 'rating',
'Best Match': 'best_match',
'Most Reviewed': 'review_count',
};
// give active class to option selected
const getSortByClass = (sortByOption) => {
if (sortBy === sortByOption) {
return styles.active;
} else {
return '';
}
};
// set the state of a sorting option
const handleSortByChange = (sortByOption) => {
setSortBy(sortByOption);
};
//handle input changes
const handleChange = (e) => {
if (e.target.name === 'what') {
setWhat(e.target.value);
} else if (e.target.name === 'where') {
setWhere(e.target.value);
}
};
const onSubmit = (e) => {
e.preventDefault();
if (where && what) {
getRestaurants({ where, what, sortBy });
setWhere('');
setWhat('');
setSortBy('best_match');
} else {
setAlert('Please fill all the inputs');
}
};
// displays sort options
const renderSortByOptions = () => {
return Object.keys(sortByOptions).map((sortByOption) => {
let sortByOptionValue = sortByOptions[sortByOption];
return (
<li
className={getSortByClass(sortByOptionValue)}
key={sortByOptionValue}
onClick={() => handleSortByChange(sortByOptionValue)}
>
{sortByOption}
</li>
);
});
};
return (
<DisplaySearchBar
onSubmit={onSubmit}
handleChange={handleChange}
renderSortByOptions={renderSortByOptions}
where={where}
what={what}
handleScriptLoad={handleScriptLoad}
/>
);
};
Search.propTypes = {
getRestaurants: PropTypes.func.isRequired,
setAlert: PropTypes.func.isRequired,
};
export default connect(null, { getRestaurants, setAlert })(Search);
DisplaySearchBar.js
import React from 'react';
import PropTypes from 'prop-types';
import { connect } from 'react-redux';
import { clearSearch } from '../../../actions/restaurantAction';
//Import React Script Libraray to load Google object
import Script from 'react-load-script';
import Fade from 'react-reveal/Fade';
import Alert from '../Alert/Alert';
import styles from './DisplaySearchBar.module.scss';
const DisplaySearchBar = ({
renderSortByOptions,
onSubmit,
where,
handleChange,
what,
handleScriptLoad,
restaurants,
clearSearch,
}) => {
const googleUrl = `https://maps.googleapis.com/maps/api/js?key=${process.env.REACT_APP_GOOGLE_API_KEY}&libraries=places`;
// {googleUrl && <Script url={googleUrl} onLoad={handleScriptLoad} />}
return (
<section className={styles.searchBar}>
<form onSubmit={onSubmit} className={styles.searchBarForm}>
<legend className="title">
<Fade left>
<h1>Where are you going to eat tonight?</h1>
</Fade>
</legend>
<Fade>
<fieldset className={styles.searchBarInput}>
<input
type="text"
name="where"
placeholder="Where do you want to eat?"
value={where}
onChange={handleChange}
id="autocomplete"
/>
<input
type="text"
name="what"
placeholder="What do you want to eat?"
onChange={handleChange}
value={what}
/>
<div className={styles.alertHolder}>
<Alert />
</div>
</fieldset>
<fieldset className={styles.searchBarSubmit}>
<input
id="mainSubmit"
className={`${styles.myButton} button`}
type="submit"
name="submit"
value="Search"
></input>
{restaurants.length > 0 && (
<button
className={`${styles.clearButton} button`}
onClick={clearSearch}
>
Clear
</button>
)}
</fieldset>
</Fade>
</form>
<article className={styles.searchBarSortOptions}>
<Fade>
<ul>{renderSortByOptions()}</ul>
</Fade>
</article>
</section>
);
};
DisplaySearchBar.propTypes = {
renderSortByOptions: PropTypes.func.isRequired,
where: PropTypes.string.isRequired,
handleChange: PropTypes.func.isRequired,
what: PropTypes.string.isRequired,
handleScriptLoad: PropTypes.func.isRequired,
restaurants: PropTypes.array.isRequired,
clearSearch: PropTypes.func.isRequired,
};
const mapStatetoProps = (state) => ({
restaurants: state.restaurants.restaurants,
});
export default connect(mapStatetoProps, { clearSearch })(DisplaySearchBar);
And Search.test.js
import Search from '../Search';
import DisplaySearchBar from '../../../layout/DisplaySearchBar/DisplaySearchBar';
const mockStore = configureStore();
describe('Search', () => {
test('renders withut errors', () => {
const initialState = {
restaurants: {},
};
const props = { setAlert: jest.fn(), getRestaurants: jest.fn() };
const store = mockStore(initialState);
const wrapper = shallow(
<Provider store={store}>
<Search {...props} />
</Provider>
);
wrapper.find(DisplaySearchBar).props();
});
});
Thanks for your help!
