TypeScript 中的 Cypress：Mocha afterEach：如果 currentTest 失败则停止 Runner

Question

目标是如果任何测试失败停止 Cypress runner，并且这些 Mocha 测试是用 TypeScript 编写的。下面的 Mocha afterEach() 有两个问题...

/// <reference types="Cypress" />

  afterEach(() => {
    if (this.currentTest.state === 'failed' && 
      this.currentTest._currentRetry === this.currentTest._retries) {
      Cypress.runner.stop();
    }
  });

问题如下：

this.currentTest.* >>> 参考 this >>> TS2532: Object is possibly 'undefined'
Cypress.runner.stop() >>> TS2339: Property 'runner' does not exist on type 'Cypress'

如何在 TypeScript 中解决这个问题并使用 // @ts-ignore 忽略它？

谢谢，感谢帮助。

Answer 1

是的，您可以使用 // @ts-ignore 。此外，您还需要使用常规函数 () {} 语法，而不是 lambda“粗箭头”语法 () => {}

参考赛普拉斯文档 : https://docs.cypress.io/guides/core-concepts/variables-and-aliases.html#Avoiding-the-use-of-this

Accessing aliases as properties with this.* will not work 
if you use arrow functions for your tests or hooks.  This is why all of our
examples use the regular function () {} syntax as opposed to the
lambda “fat arrow” syntax () => {}.

代码看起来像这样

afterEach(function() {
    if (this.currentTest.state === 'failed' && 
      //@ts-ignore
      this.currentTest._currentRetry === this.currentTest._retries) {
      //@ts-ignore
      Cypress.runner.stop();
    }
  });
