Question

我正尝试运行一个黄瓜功能文件，并且在测试的每个步骤之后，我想在cumul html报告中捕获一个屏幕截图。我使用了AfterStep钩子，如下所示（我也使用了After，Before和BeforeAll钩子，它们都可以正常运行）：

import { AfterStep } from "cucumber";

AfterStep(async function() {
  const screenshot = await browser.takeScreenshot();
  this.attach(screenshot, "image/png"); 
});

当我尝试运行测试时，出现错误

E/launcher - Error: TypeError: cucumber_2.AfterStep is not a function

我试图修改node_modules/@types/cucumber/index.d.ts文件并在其中添加以下内容：

export interface Hooks {
   AfterStep(code: HookCode): void;
}

还用以下条目修改了node_modules/cucumber/dist/cucumber.js：

var AfterStep = methods.AfterStep;
exports.AfterStep = AfterStep;
...
function () {
    ...
    AfterStep: this.defineTestRunHook('afterTestRunHookDefinitions'),
    ...
}

但是，我仍然会遇到此错误。在使用BeforeAll，Before，After挂钩时，我不必进行所有这些修改。 PS：使用的黄瓜版本5.1.0，量角器5.4.2，打字稿3.6.2

带黄瓜AfterStep钩的量角器抛出TypeError：Cucumul_2.AfterStep不是一个函数
