* rename backend certSlug and README

* update i18n folder names and keys

* test: add legacy path redirect tests

This uses serve.json from the client-config repo, since we currently use
that in production

* fix: create public dir before moving serve.json

* fix: add missing script

* refactor: collect redirect tests

* test: convert to cy.location for stricter tests

* rename certificate folder to 00-certificates

* change crowdin config to recognise new certificates location

* allow translations to be used

* add forwards slashes to path redirects

* fix cypress path tests again

* plese cypress

* fix: test different challenge

Okay so I literally have no idea why this one particular challenge
fails in Cypress Firefox ONLY. Tom and I paired and spun a full build
instance and confirmed in Firefox the page loads and redirects as
expected. Changing to another bootstrap challenge passes Cypress firefox
locally. Absolutely boggled by this.

AAAAAAAAAAAAAAA

* fix: separate the test

Okay apparently the test does not work unless we separate it into
a different `it` statement.

title: Accede a propiedades "props" usando this.props
challengeType: 6
forumTopicId: 301375
dashedName: access-props-using-this-props
---
# --description--
Los últimos desafíos cubrieron las formas básicas de pasar propiedades a un componente hijo. Pero, ¿qué pasa si el componente hijo al que se le pasa una propiedad es un componente de clase ES6, en lugar de un componente funcional sin estado? Los componentes de clase ES6 usan una convención un poco diferente para acceder a las propiedades.
Cada vez que se hace referencia a un componente de clase en sí mismo, se utiliza la palabra clave `this`. Para acceder a las propiedades dentro de un componente de clase, se antepone al código que se utiliza para acceder a él con `this`. Por ejemplo, si un componente de clase de ES6 tiene una propiedad llamada `data`, se escribirá `{this.props.data}` en JSX.
# --instructions--
Renderiza una instancia del componente `ReturnTempPassword` en el componente padre `ResetPassword`. Aquí, dale a `ReturnTempPassword` una propiedad de `tempPassword` y asígnale un valor de una cadena que tenga al menos 8 caracteres. Dentro del componente hijo, `ReturnTempPassword`, accede a la propiedad `tempPassword` dentro de las etiquetas `strong` para asegurarte que el usuario vea una contraseña temporal.
# --hints--
El componente `ResetPassword` debe devolver un único elemento `div`.
```js
assert(
(function () {
const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
return mockedComponent.children().type() === 'div';
})()
);
```
El cuarto componente hijo de `ResetPassword` debe ser el componente `ReturnTempPassword`.
```js
assert(
(function () {
const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
return (
mockedComponent.children().childAt(3).name() === 'ReturnTempPassword'
);
})()
);
```
El componente `ReturnTempPassword` debe tener una propiedad llamada `tempPassword`.
```js
assert(
(function () {
const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
return mockedComponent.find('ReturnTempPassword').props().tempPassword;
})()
);
```
La propiedad `tempPassword` de `ReturnTempPassword` debe ser igual a una cadena de al menos 8 caracteres.
```js
assert(
(function () {
const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
const temp = mockedComponent.find('ReturnTempPassword').props()
.tempPassword;
return typeof temp === 'string' && temp.length >= 8;
})()
);
```
El componente `ReturnTempPassword` debe mostrar la contraseña creada en la propiedad `tempPassword` dentro de las etiquetas `strong`.
```js
assert(
(function () {
const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
return (
mockedComponent.find('strong').text() ===
mockedComponent.find('ReturnTempPassword').props().tempPassword
);
})()
);
```
# --seed--
## --after-user-code--
```jsx
ReactDOM.render(<ResetPassword />, document.getElementById('root'))
```

```jsx
class ReturnTempPassword extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
{ /* Change code below this line */ }
<p>Your temporary password is: <strong></strong></p>
{ /* Change code above this line */ }
</div>
);
}

}
render() {
return (
<div>
<h2>Reset Password</h2>
<h3>We've generated a new temporary password for you.</h3>
<h3>Please reset this password from your account settings ASAP.</h3>
{ /* Change code below this line */ }
{ /* Change code above this line */ }
</div>
);
}
};

}
render() {
return (
<div>
<p>Your temporary password is: <strong>{this.props.tempPassword}</strong></p>
</div>

<h3>Please reset this password from your account settings ASAP.</h3>
{ /* Change code below this line */ }
<ReturnTempPassword tempPassword="serrPbqrPnzc" />
{ /* Change code above this line */ }
</div>
