The last several challenges covered the basic ways to pass props to child components. But what if the child component that you're passing a prop to is an ES6 class component, rather than a stateless functional component? The ES6 class component uses a slightly different convention to access props.

Anytime you refer to a class component within itself, you use the this keyword. To access props within a class component, you preface the code that you use to access it with this. For example, if an ES6 class component has a prop called data, you write {this.props.data} in JSX.

--instructions--

Render an instance of the Welcome component in the parent component App. Here, give Welcome a prop of name and assign it a value of a string. Within the child, Welcome, access the name prop within the strong tags.

--hints--

The App component should return a single div element.

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

The child of App should be the Welcome component.

assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(App));
    return (
      mockedComponent.children().childAt(0).name() === 'Welcome'
    );
  })()
);

The Welcome component should have a prop called name.

assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(App));
    return mockedComponent.find('Welcome').props().name;
  })()
);

The Welcome component should display the string you pass as the name prop within strong tags.

assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(App));
    return (
      mockedComponent.find('strong').text() ===
      mockedComponent.find('Welcome').props().name
    );
  })()
);
