--description--
La possibilità di impostare delle proprietà predefinite è una caratteristica utile in React. Per sovrascrivere gli elementi predefiniti si devono impostare esplicitamente i valori delle proprietà per un componente.
--instructions--
Il componente ShoppingCart ora presenta un componente figlio Items. Questo componente Items ha una proprietà di default quantity impostata all'intero 0. Sovrascrivi la proprietà predefinita passando un valore di 10 per quantity.
Nota: Ricorda che la sintassi per aggiungere una proprietà a un componente è simile a quella degli attributi HTML. Tuttavia, poiché il valore per la quantity è un numero intero, non andrà tra virgolette ma dovrebbe essere racchiusa tra parentesi graffe. Ad esempio, {100}. Questa sintassi dice a JSX di interpretare il valore all'interno delle parentesi graffe direttamente come JavaScript.
--hints--
Il componente ShoppingCart dovrebbe effettuare il render.
assert(
(function () {
const mockedComponent = Enzyme.mount(React.createElement(ShoppingCart));
return mockedComponent.find('ShoppingCart').length === 1;
})()
);
Il componente Items dovrebbe effettuare il render.
assert(
(function () {
const mockedComponent = Enzyme.mount(React.createElement(ShoppingCart));
return mockedComponent.find('Items').length === 1;
})()
);
Il componente Items dovrebbe avere una proprietà di { quantity: 10 } passata dal componente ShoppingCart.
(getUserInput) =>
assert(
(function () {
const mockedComponent = Enzyme.mount(React.createElement(ShoppingCart));
return (
mockedComponent.find('Items').props().quantity == 10 &&
getUserInput('index')
.replace(/ /g, '')
.includes('<Itemsquantity={10}/>')
);
})()
);
