* 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.

--description--

Os últimos desafios cobriram as formas básicas de passar propriedades para componentes filhos. Mas e se o componente filho para o qual você está passando uma propriedade é um componente de classe ES6, em vez de um componente funcional sem estado? O componente da classe ES6 usa uma convenção ligeiramente diferente para acessar as propriedades.

Sempre que você se refere a um componente de classe dentro dele mesmo, você usa a palavra-chave this. Para acessar props dentro de um componente de classe, você adiciona this ao início do código que você usar para acessá-lo. Por exemplo, se um componente de classe ES6 possui uma prop chamada data, você escreve {this.props.data} em JSX.

--instructions--

Renderize uma instância do componente ReturnTempPassword no componente parente ResetPassword. Aqui, dê a ReturnTempPassword à prop tempPassword e atribua a ela o valor de uma string que tenha pelo menos 8 caracteres. Dentro do filho, ReturnTempPassword, acesse a prop tempPassword dentro das tags strong para certificar-se que o usuário veja a senha temporária.

--hints--

O componente ResetPassword deve retornar um único elemento div.

assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
    return mockedComponent.children().type() === 'div';
  })()
);

O quarto filho de ResetPassword deve ser o componente ReturnTempPassword.

assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
    return (
      mockedComponent.children().childAt(3).name() === 'ReturnTempPassword'
    );
  })()
);

O componente ReturnTempPassword deve ter uma prop chamada tempPassword.

assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
    return mockedComponent.find('ReturnTempPassword').props().tempPassword;
  })()
);

A prop tempPassword de ReturnTempPassword deve ser igual uma string de pelo menos 8 caracteres.

assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
    const temp = mockedComponent.find('ReturnTempPassword').props()
      .tempPassword;
    return typeof temp === 'string' && temp.length >= 8;
  })()
);

O componente ReturnTempPassword deve exibir a senha que você criou como a prop tempPassword dentro das tags strong.

assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
    return (
      mockedComponent.find('strong').text() ===
      mockedComponent.find('ReturnTempPassword').props().tempPassword
    );
  })()
);

--seed--

--after-user-code--

ReactDOM.render(<ResetPassword />, document.getElementById('root'))

--seed-contents--

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>
    );
  }
};

class ResetPassword extends React.Component {
  constructor(props) {
    super(props);

  }
  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>
    );
  }
};

--solutions--

class ReturnTempPassword extends React.Component {
  constructor(props) {
    super(props);

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

class ResetPassword extends React.Component {
  constructor(props) {
    super(props);

  }
  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 */ }
          <ReturnTempPassword tempPassword="serrPbqrPnzc" />
          { /* Change code above this line */ }
        </div>
    );
  }
