Description
Instructions
TypesOfFood
component is already rendering a component called Vegetables
. Also, there is the Fruits
component from the last challenge.
Nest two components inside of Fruits
— first NonCitrus
, and then Citrus
. Both of these components are provided for you in the background. Next, nest the Fruits
class component into the TypesOfFood
component, below the h1
header and above Vegetables
. The result should be a series of nested components, which uses two different component types.
Tests
tests:
- text: The <code>TypesOfFood</code> component should return a single <code>div</code> element.
testString: assert((function() { const mockedComponent = Enzyme.mount(React.createElement(TypesOfFood)); return mockedComponent.children().type() === 'div'; })(), 'The <code>TypesOfFood</code> component should return a single <code>div</code> element.');
- text: The <code>TypesOfFood</code> component should return the <code>Fruits</code> component.
testString: assert((function() { const mockedComponent = Enzyme.mount(React.createElement(TypesOfFood)); return mockedComponent.children().childAt(1).name() === 'Fruits'; })(), 'The <code>TypesOfFood</code> component should return the <code>Fruits</code> component.');
- text: The <code>Fruits</code> component should return the <code>NonCitrus</code> component and the <code>Citrus</code> component.
testString: assert((function() { const mockedComponent = Enzyme.mount(React.createElement(TypesOfFood)); return (mockedComponent.find('Fruits').children().find('NonCitrus').length === 1 && mockedComponent.find('Fruits').children().find('Citrus').length === 1); })(), 'The <code>Fruits</code> component should return the <code>NonCitrus</code> component and the <code>Citrus</code> component.');
- text: The <code>TypesOfFood</code> component should return the <code>Vegetables</code> component below the <code>Fruits</code> component.
testString: assert((function() { const mockedComponent = Enzyme.mount(React.createElement(TypesOfFood)); return mockedComponent.children().childAt(2).name() === 'Vegetables'; })(), 'The <code>TypesOfFood</code> component should return the <code>Vegetables</code> component below the <code>Fruits</code> component.');
Challenge Seed
class Fruits extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
<h2>Fruits:</h2>
{ /* change code below this line */ }
{ /* change code above this line */ }
</div>
);
}
};
class TypesOfFood extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
<h1>Types of Food:</h1>
{ /* change code below this line */ }
{ /* change code above this line */ }
<Vegetables />
</div>
);
}
};
Before Test
class NonCitrus extends React.Component {
render() {
return (
<div>
<h4>Non-Citrus:</h4>
<ul>
<li>Apples</li>
<li>Blueberries</li>
<li>Strawberries</li>
<li>Bananas</li>
</ul>
</div>
);
}
};
class Citrus extends React.Component {
render() {
return (
<div>
<h4>Citrus:</h4>
<ul>
<li>Lemon</li>
<li>Lime</li>
<li>Orange</li>
<li>Grapefruit</li>
</ul>
</div>
);
}
};
class Vegetables extends React.Component {
render() {
return (
<div>
<h2>Vegetables:</h2>
<ul>
<li>Brussel Sprouts</li>
<li>Broccoli</li>
<li>Squash</li>
</ul>
</div>
);
}
};
After Test
ReactDOM.render(<TypesOfFood />, document.getElementById('root'))
Solution
class Fruits extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
<h2>Fruits:</h2>
{ /* change code below this line */ }
<NonCitrus />
<Citrus />
{ /* change code above this line */ }
</div>
)
}
}
class TypesOfFood extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
<h1>Types of Food:</h1>
{ /* change code below this line */ }
<Fruits />
{ /* change code above this line */ }
<Vegetables />
</div>
);
}
};
