Cypress集成ReportPortal和gmail-tester报rp_Log任务未注册如何解决

问题原因 #

你在plugins/index.js文件中对module.exports进行了两次赋值，第二次导出的插件配置直接覆盖了此前注册ReportPortal插件的逻辑，导致ReportPortal相关的rp_Log、rp_screenshot等内置任务都没有被正确注册，只有你新增的gmail:get-messages任务被识别，所以运行时报错。

修复方案 #

将ReportPortal的注册逻辑合并到同一个导出的插件函数中即可，修改后的plugins/index.js代码如下：

/// <reference types="cypress" />
// ***********************************************************
// This example plugins/index.js can be used to load plugins
//
// You can change the location of this file or turn off loading
// the plugins file with the 'pluginsFile' configuration option.
// ***********************************************************

// This function is called when a project is opened or re-opened (e.g. due to
// the project's config changing)

/**
 * @type {Cypress.PluginConfig}
 */
// eslint-disable-next-line no-unused-vars
const registerReportPortalPlugin = require('@reportportal/agent-js-cypress/lib/plugin');
const debug = require('debug');
const path = require('path');
const gmail_tester = require('gmail-tester');


module.exports = (on, config) => {
  // 注册ReportPortal插件
  registerReportPortalPlugin(on);
  
  on("before:browser:launch", (browser = {}, launchOptions) => {
    if (browser.name === "chrome"&& browser.isHeadless) {
      launchOptions.args.push('--disable-gpu');
      return launchOptions;
    }
  });
  on("task", {
    "gmail:get-messages": async args => {
      const messages = await gmail_tester.get_messages(
        path.resolve(__dirname, "credentials.json"),
        path.resolve(__dirname, "token.json"),
        args.options
      );
      return messages;
    }
  });
};

修改完成后重新运行测试，ReportPortal相关任务和gmail获取邮件的任务就可以同时正常工作了。
