使用Cypress和节点imap接收邮件的测试失败，缺少'；净'；模块

我想使用Cypress中的node imap或NPM的imap包来检查是否收到了某些电子邮件并检查其内容

当我尝试从imap github和文档中获取的示例的基本副本时，它失败，出现以下错误：

./node_modules/imap/lib/Connection.js

            as directory
              /Users/username/Documents/test-e2e/node_modules/net doesn't exist

因此，无法运行任何测试。 我试着寻找这个“网络”，也和imap包结合在一起，但我真的找不到任何解决方案。

甚至可以将Imap与Cypress一起使用吗？

Cypress在浏览器中执行其代码。因此，您不能使用此类NPM模块。 要解决此问题，必须使用

cy.task

。Cypress在节点进程内执行任务，因此您可以使用任何所需的库。这些任务必须在插件文件中定义，因为该文件是在节点上下文中加载的

因此，您必须在

cypress.json

中告诉cypress您正在使用插件文件：

{
    ...
    "pluginsFile": "cypress/plugins/plugins.js",
    ...
  }

然后在

plugins.js

中定义一个任务：

on('task', {
    sendMail({ subject, to, body }) {
      return getEmail(subject, to, body);
    }
  });

getEmail

应该是您的示例代码

使用如下任务：

cy.task("sendMail", { subject, to, body }, { timeout: 30000 });
