我想在 Cypress 中使用 node-imap 或来自 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中的基本副本时，它失败并出现以下错误：

./node_modules/imap/lib/Connection.js
Module not found: Error: Can't resolve 'net' in '/Users/username/Documents/test-e2e/node_modules/imap/lib'

            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”，也结合了 imap 包，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？

赛普拉斯在浏览器中执行它的代码。所以你不能使用这样的 NPM 模块。要解决此问题，您必须使用cy.task. 赛普拉斯在节点进程中执行任务，因此您可以使用任何您想要的库。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。

所以你必须告诉赛普拉斯cypress.json你正在使用插件文件：

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

然后在中定义一个任务plugins.js：

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

getEmail应该是您的示例代码。

使用这样的任务：

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