我正在运行一个 cucumber 功能文件在柏树亚军。

  • 数据库功能 *
Feature: DB

    Scenario: db test
        When i try to connect to db
        Then i get the code

我的步骤定义如下

  • 数据库.ts*
import { Given, When, Then, Before } from "cypress-cucumber-preprocessor/steps";

When(/^i try to connect to db$/, () => {
  cy.task('log', 'This is the config task')

});

Then(/^i get the code$/, () => {
    return true;
});

我的 index.js 文件在plugins文件夹下

const browserify = require('@cypress/browserify-preprocessor');
const cucumber = require('cypress-cucumber-preprocessor').default;

module.exports = (on, config) => {
  const options = {
    ...browserify.defaultOptions,
    typescript: require.resolve('typescript'),
  };

  on('file:preprocessor', cucumber(options));
};

module.exports = (on, config) => {
  on('task', {
    log(message) {
      console.log(message)

      return null
    },
  })
}

我遇到过一些使用webpack-preprocessor的解决方案，但我没有使用webpack-preprocessor，而是使用browserify-preprocessor和typescript（我也尝试过webpack-preprocessor，但没有效果）。
当我在cypress runner中运行这个程序时，我得到了以下错误x1c 0d1x
当我从index.js文件中删除配置任务log，并注解掉db.ts文件中的cy.task调用时，代码工作顺利。只有当我在index.js文件中添加配置任务时，我才得到以下错误。

Error: Webpack Compilation Error
./cypress/integration/db.feature 3:17
Module parse failed: Unexpected token (3:17)

我也遇到过同样的问题，但在我的例子中，解决方案是将plugin/index.js的内容从cypress.config.ts文件传递到setupNodeEvents。
我使用的是cypress10.0.0版本，根据官方文档，插件文件被弃用。

e2e: {
    setupNodeEvents(on, config) {
      const cucumber = require('cypress-cucumber-preprocessor').default
      const browserify = require('@cypress/browserify-preprocessor');
      const options = {
        ...browserify.defaultOptions,
        typescript: require.resolve('typescript'),
      };
      on('file:preprocessor', cucumber(options));
    },
   ...
  }

修复方法是将自定义任务放在与browserify相同的modul.export下。index.js文件中有两个不同的modul.export会导致问题。
这是我最后的index.js文件

const browserify = require('@cypress/browserify-preprocessor');
const cucumber = require('cypress-cucumber-preprocessor').default;

module.exports = (on, config) => {
  const options = {
    ...browserify.defaultOptions,
    typescript: require.resolve('typescript'),
  };

  on('file:preprocessor', cucumber(options));
  on('task', {
    log(message) {
      console.log(message)

      return null
    },
  })
};

你需要browserify来运行 cucumber 测试。
在cypress.config.js文件中添加以下代码

const { defineConfig } = require("cypress");
const preprocessor = require("@badeball/cypress-cucumber-preprocessor");
const browserify = require("@badeball/cypress-cucumber-preprocessor/browserify");

async function setupNodeEvents(on, config) {
  // This is required for the preprocessor to be able to generate JSON reports after each run, and more,
  await preprocessor.addCucumberPreprocessorPlugin(on, config);

  on("file:preprocessor", browserify.default(config));

  // Make sure to return the config object as it might have been modified by the plugin.
  return config;
}

module.exports = defineConfig({
  e2e: {
    specPattern: "**/*.feature",
    setupNodeEvents,
  },
});

在package.json中添加以下依赖项

"@cypress/browserify-preprocessor": "latest"

在步骤中添加此行

import { Given, When, Then } from "@badeball/cypress-cucumber-preprocessor";

使用npm i再次安装依赖项
执行你的测试它会成功的！
