如何将电子邮件服务与Cypress 10集成
我试图整合电子邮件服务与柏树电子邮件测试。我遵循了这个示例项目https://github.com/bahmutov/cypress-ethereal-email-example，这个项目是为Cypress版本<10编写的，我试图使它在Cypress 10.3.1中工作。遵循以下步骤：
directory
- Tried
- 在柏树中创建了电子邮件-Account.js/支持复制柏树/插件/index.js在cypress.config.js中
cypress.config.js含量
const { defineConfig } = require('cypress')
const fs = require('fs');
const { isFileExist } = require('cy-verify-downloads');
const xlsx = require('node-xlsx').default;
const path = require('path');
const exec = require('child_process');
const makeEmailAccount = require('./cypress/support/email-account')
module.exports = defineConfig({
e2e: {
setupNodeEvents (on, config) {
const emailAccount = makeEmailAccount()
on('task', {
getUserEmail() {
const emailAccount = makeEmailAccount()
console.log(emailAccount)
return new Promise((resolve) => {
// tasks should not resolve with undefined
console.log(emailAccount)
return resolve(emailAccount.email)
})
},
getLastEmail() {
return emailAccount.getLastEmail()
},
})
})在尝试测试电子邮件时，我遇到了以下错误：
task getUserEmail
CypressError
cy.task('getUserEmail') failed with the following error:
The task 'getUserEmail' returned undefined. You must return a value, null, or a promise that resolves to a value or null to indicate that the task was handled.
The task handler was:
getUserEmail() {
return new Promise((resolve) => {
// tasks should not resolve with undefined
return resolve(emailAccount.email)
})
}
Fix this in your setupNodeEvents method here:
/Users/ashoknegi/Sites/renesas-d9/cypress.config.js有人能帮忙解决这个问题吗？我认为问题在于配置文件中的异步函数调用。我检查了异步任务，发现了这个链接，并试图以同样的方式实现它。https://docs.cypress.io/api/commands/task#Return-a-Promise-from-an-asynchronous-task有没有人将电子邮件服务集成到Cypress 10上？任何帮助都很感激。

要将Gleb的v9 /plugins/index.js转换为v10 cypress.config.js，您需要setupNodeEvents()是异步的，并等待makeEmeialAccount()的结果。
香柏( Cypress v9 )
module.exports = async (on) => {
const emailAccount = await makeEmailAccount()
on('task', {
getUserEmail() {
return emailAccount.email
},
getLastEmail() {
return emailAccount.getLastEmail()
},
})
}香柏( Cypress v10 )
e2e: {
setupNodeEvents: async (on, config) => {
const emailAccount = await makeEmailAccount()
on('task', {
getUserEmail() {
return emailAccount.email
},
getLastEmail() {
return emailAccount.getLastEmail()
},
})
},从技术上讲，使用Promise.resolve()是一种合法的方法，但由于您没有等待，所以需要使用.then(emailAccount => resolve(emailAccount))模式。
e2e: {
setupNodeEvents (on, config) {
on('task', {
getUserEmail() {
return new Promise((resolve) => {
makeEmailAccount().then(emailAccount => {
resolve(emailAccount.email)
})
})
}
}
}
},然而，Promise.resolve()并不像async/await方法那么有用，因为在测试中添加getLastEmail()或调用getUserEmail()任务两次实际上是在每次打电话时发出不同的电子邮件。
