[英]Webpack Compilation Error with Cypress 10 and Cucumber in Angular
[英]Cypress in Angular with cucumber > process is not defined
我尝试在 Cucumber 和 TypeScript 的 Angular 12 项目中使用赛普拉斯进行 e2e 测试。
Cypress 本身通过npx cypress open
成功启动,我创建的功能文件如下所示:
我在这里发现了类似的问题,但没有可以应用的解决方案。 我相信会发生此错误,因为我使用的是赛普拉斯自己的浏览器,并且流程变量在那里不可用。 我还查看了这个存储库,但没有找到任何可以解决这个问题的东西。
该项目的package.json如下所示:

请让我知道,如果需要任何其他信息,我将很乐意提供。
process
undefined
,因为在您的情况下,代码正在浏览器中执行。
您可能使用了与 webpack 4 一起使用的配置,该配置为path
提供了模拟 api(您已经包含了后备)或在本例中为process
。 Webpack 5 发行说明:node.process 已删除
看起来 cucumber 解析器实际上是在浏览器上下文中使用此加载器通过将 cucumber 代码发送到浏览器包来执行的。
如果没有特别的理由,我建议不要使用 webpack。 您甚至不需要使用最新的 cyperss 版本编译 typescript。 相反,我建议使用cypress-cucumber-preprocessor 自述文件中建议的设置:
如果需要 webpack,您可以尝试模拟流程变量。 我验证了在将 webpack 5 与原始示例存储库一起使用时,将以下内容添加到support/index.js
是有效的:
window.process = {
argv: [],
env: {},
};
