Cypress Component Testing, ReactJS, and TailwindCSS

Question

有人知道我如何从测试文件加载TailwindCSS吗?

我尝试使用相同的方法，我在VueJS上使用，导入css文件，但它只是不加载样式。

这是我添加柏树组件测试的提交:https://github.com/vicainelli/cypress-component-testing-react-tailwindcss/commit/2fa25833cb965fadfeda6c53b80a23bb12b3b1c5

我知道在mount中有可以传递样式表的选项，例如

:

mount(<App />, { stylesheet: "https://unpkg.com/tailwindcss@^2/dist/tailwind.min.css" });

但是我想使用我的自定义css。

Cypress文档有一个打字错误，你应该导入这个

import 'tailwindcss/dist/tailwind.min.css'

不是这个

import 'tailwindcss/dist/tailwindcss.min.css'   // causes error, not in node_modules 

import React from 'react';
import { mount } from '@cypress/react';
import App from './App';
import './index.css';
import 'tailwindcss/dist/tailwind.min.css'
it('should renders the App correctly', () => {
mount(<App />) 
cy.get('h1').contains('Cypress Component Testing with Tailwind CSS')
.should('have.css', 'font-family') 
.and('match', /Georgia/)          // passes
});

或可以在cypress/plugins/index.js

中使用cracao插件

yarn add -D @cypress/react
//or
npm install -D @cypress/react

const cracoConfig = require('../../craco.config.js')
const injectDevServer = require('@cypress/react/plugins/craco')
module.exports = (on, config) => {
injectDevServer(on, config, cracoConfig)
return config
}

激活craco.config.js的内容(你已经有了)

module.exports = {
style: {
postcss: {
plugins: [
require('tailwindcss'),
require('autoprefixer'),
],
},
},
}

import React from 'react';
import { mount } from '@cypress/react';
import App from './App';
import './index.css';
// import 'tailwindcss/dist/tailwind.min.css'    // not required, plugin works
it('should renders the App correctly', () => {
mount(<App />) 
cy.get('h1').contains('Cypress Component Testing with Tailwind CSS')
.should('have.css', 'font-family') 
.and('match', /Georgia/)          // passes
});

您可以像在cypress 7.0迁移指南中提到的那样直接导入顺风CSS。

不建议使用mountingOptions.stylesheets。

require('tailwindcss/dist/tailwindcss.min.css')

整个代码片段:

// In the majority of modern style-loaders,
// these styles will be injected into document.head when they're imported below
require('./index.scss')
require('tailwindcss/dist/tailwindcss.min.css')
const { mount } = require('@cypress/react')
const Button = require('./Button')
it('renders a Button', () => {
// This button will render with the Tailwind CSS styles
// as well as the application's index.scss styles
mount(<Button />)
})
