  "main": "index.js",
  "scripts": 
    "test": "testcafe"
  ,
  "author": "",
  "license": "ISC",
  "dependencies": 
    "@ffmpeg-installer/ffmpeg": "^1.1.0",
    "cucumber": "^7.1.0",
    "gradle": "^1.2.4",
    "testcafe": "^1.16.1",
    "testcafe-angular-selectors": "^0.4.1"
  ,
  "description": "",
  "devDependencies": 
    "@cucumber/cucumber": "^8.0.0-rc.1"

步骤def中的导入格式

const assert = require('assert');
const  Given, When, Then  = require('@cucumber/cucumber');

【参考方案1】：

目前，TestCafe 没有与 Cucumber 的官方集成。在 TestCafe 的 GitHub 存储库中跟踪 this 问题以了解其进度。
