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. >:( >:( >:( >:( Co-authored-by: Sujal Gupta <55016909+heysujal@users.noreply.github.com> Co-authored-by: Noor Fakhry <65724923+NoorFakhry@users.noreply.github.com> Co-authored-by: Oliver Eyton-Williams <ojeytonwilliams@gmail.com> Co-authored-by: Nicholas Carrigan (he/him) <nhcarrigan@gmail.com>

--description--
上一个挑战显示了组合两个组件的简单方法,但是有许多不同的方法可以把 React 组件组合在一起。
组件组合是 React 的强大功能之一。 当使用 React 时,应当先用组件的思路考虑清楚用户界面的结构(如上一个挑战中的 App 示例)。 可以将 UI 分解为基本的构建块,这些构建块就是组件。 这样做有助于将负责 UI 的代码与负责处理应用程序逻辑的代码分开, 并可以大大简化复杂项目的开发和维护。
--instructions--
代码编辑器中定义了两个功能组件,分别是 TypesOfFruit
和 Fruits
。 请用组合或者嵌套把 TypesOfFruit
组件放到 Fruits
组件中, 然后把 Fruits
组件放到 TypesOfFood
组件中。 结果应该是子组件嵌套在父组件中,父组件嵌套在它本身的父组件中!
--hints--
TypesOfFood
组件应该返回单个 div
元素。
assert(Enzyme.shallow(React.createElement(TypesOfFood)).type() === 'div');
TypesOfFood
组件应该返回 Fruits
组件。
assert(
Enzyme.shallow(React.createElement(TypesOfFood)).props().children[1].type
.name === 'Fruits'
);
Fruits
组件应该返回 TypesOfFruit
组件。
assert(
Enzyme.mount(React.createElement(TypesOfFood)).find('h2').html() ===
'<h2>Fruits:</h2>'
);
TypesOfFruit
组件应该返回 h2
和 ul
元素。
assert(
Enzyme.mount(React.createElement(TypesOfFood)).find('ul').text() ===
'ApplesBlueberriesStrawberriesBananas'
);
