Reactjs 使用酶测试时,材料UI的样式和道具不呈现+;开玩笑
我正在为一个组件编写一个测试,该组件使用Jest从MaterialUI包装在一个withStyles()中。我搜索了很多例子,但没有找到答案 以下是我的文件: Login.jsReactjs 使用酶测试时,材料UI的样式和道具不呈现+;开玩笑,reactjs,jestjs,enzyme,Reactjs,Jestjs,Enzyme,我正在为一个组件编写一个测试,该组件使用Jest从MaterialUI包装在一个withStyles()中。我搜索了很多例子,但没有找到答案 以下是我的文件: Login.js import React, { Component } from 'react'; import { connect } from 'react-redux'; import * as Actions from 'auth/store/actions/index'; import { bindActionCreators

我删除了类。卡
并尝试了,然后我得到了以下错误:
登录›在不崩溃的情况下呈现
TypeError: Cannot read property 'card' of undefined
TypeError: Cannot read property 'resetErrorMessage' of undefined
我希望包装器组件的行为与没有withStyles()组件的包装器相同。看起来您在测试包装的组件时没有传递任何道具,而组件需要传递一些道具 我认为当你向它传递一些必要的道具时,它会起作用,如下所示:
- 导出
Login.js中的
类Login
导出类登录{
// ...
}
- 然后导入到测试:
//您应该导入'Login'类以单独测试
从“/Login”导入{Login};
测试('在不崩溃的情况下呈现',()=>{
常量道具={
课程:{
卡片:“yourCardClass”,
},
resetErrorMessage:jest.fn(),
submitMerritosLogin:jest.fn(),
};
常量包装器=浅();
//应该在组件挂载时调用
expect(props.resetErrorMessage).toHaveBeenCalled();
expect(wrapper.find('Button').text()).toEqual('Sign-in');
});
感谢您的回复,我如您所说尝试了,但出现了类似登录的错误›遇到了一个声明异常expect(jest.fn())。TohaveBeenCall()希望调用了模拟函数,但没有调用。它应该可以工作。无论如何,请尝试删除该断言,然后检查您的上述异常是否消失?还有一件事,您还应该导出类登录
,以便于测试您的组件,而不是通过HOC组件从中检索。我不知道如何导出以进行测试。我的项目中的所有组件都是临时的。我可以单独导出以进行测试吗。请给我举个例子,因为我刚刚开始更新答案,以反映我提到的内容
TypeError: Cannot read property 'resetErrorMessage' of undefined
