--description--
Há outra forma de acessar o state
em um componente. No método render()
, antes da instrução return
, você pode escrever JavaScript diretamente. Por exemplo, você poderia declarar funções, acessar dados de state
ou props
, executar computações nesses dados, entre outras coisas. Em seguida, você pode atribuir quaisquer dados para variáveis, que você tem acesso na instrução return
.
--instructions--
No método de renderização do MyComponent
, defina uma const
chamada name
e defina-a igual ao valor do nome no state
do componente. Como você pode escrever JavaScript diretamente nesta parte do código, você não precisa incluir essa referência em chaves.
Em seguida, na instrução return, renderize este valor em uma tag h1
usando a variável name
. Lembre-se, você precisa usar a sintaxe JSX (chaves para JavaScript) na instrução de retorno.
--hints--
MyComponent
deve ter uma chave name
com o valor freeCodeCamp
armazenado no seu state.
assert(
Enzyme.mount(React.createElement(MyComponent)).state('name') ===
'freeCodeCamp'
);
MyComponent
deve renderizar um título h1
que está dentro de um único div
.
assert(
/<div><h1>.*<\/h1><\/div>/.test(
Enzyme.mount(React.createElement(MyComponent)).html()
)
);
A tag h1
renderizada deve ter uma referência a {name}
.
(getUserInput) =>
assert(/<h1>\n*\s*\{\s*name\s*\}\s*\n*<\/h1>/.test(getUserInput('index')));
O título h1
renderizado deve conter apenas texto renderizado do estado do componente.
async () => {
const waitForIt = (fn) =>
new Promise((resolve, reject) => setTimeout(() => resolve(fn()), 250));
const mockedComponent = Enzyme.mount(React.createElement(MyComponent));
const first = () => {
mockedComponent.setState({ name: 'TestName' });
return waitForIt(() => mockedComponent.html());
};
const firstValue = await first();
assert(firstValue === '<div><h1>TestName</h1></div>');
};
