,所以我无法从父元组件中传递出来,也无法成功地将它们设置为自己。目前,我并不是要特别测试任何内容。只是组件"存在"而没有错误
组件代码:
import React, { Component } from 'react';
import TodoItem from './TodoItem';
class TodoList extends Component {
renderTodos = () => {
const { todos } = this.props;
return todos.map(todo => {
return <TodoItem key={todo.id} {...todo} />;
});
};
render() {
return (
<div>
{this.renderTodos()}
</div>
);
}
}
export default TodoList;
测试代码:
import React from 'react';
import { shallow } from 'enzyme';
import renderer from 'react-test-renderer';
import TodoList from './TodoList';
import TodoItem from './TodoItem';
describe(TodoList, () => {
const todos = [
{
id: 1,
text: 'Walk the walk'
},
{
id: 2,
text: 'Talk the talk'
}
];
const component = shallow(<TodoList todos={todos} />);
it('should exist', () => {
const component = renderer.create(<TodoList />);
const tree = component.toJSON();
expect(tree).toMatchSnapshot();
});
});
请帮忙。开玩笑的新手,一般是测试的新手。
创建组件的浅实例时,您需要传递您在零件中使用有条件检查的道具
const component = shallow(<TodoList todos={[]}/>);
和
const component = renderer.create(<TodoList todos={[]}/>);
