Protractor+Typescript框架并行执行Feature后Cucumber报告未更新

• 已配置Protractor+Cucumber实现Feature文件并行执行，但执行完成后Cucumber报告始终仅显示最后一次执行结果
• 每个Feature执行后都会生成独立的JSON文件，怀疑是导致报告异常的诱因

以下是针对你的config.ts需要调整的关键配置项：

1. 修正JSON报告的生成路径，避免并行时文件覆盖 #

在cucumberOpts的format配置中，将固定文件名改为带进程ID占位符的路径，确保每个并行实例生成唯一的JSON文件：

cucumberOpts: {
  // 其他配置不变
  format: 'json:./reports/json/cucumber-report-<%= process.pid %>.json',
  require: [
    './StepDefinitions/**/*.js'
  ]
},

说明：<%= process.pid %>会自动替换为当前进程的ID，避免多个并行进程同时写入同一个JSON文件导致覆盖。

2. 统一使用protractor-multiple-cucumber-html-reporter-plugin生成合并报告 #

你当前同时启用了两种报告生成逻辑（onComplete中的cucumber-html-reporter和plugins中的多报告插件），这会导致冲突。建议保留后者，因为它专门针对并行执行场景设计：

• 移除onComplete中的报告生成代码
• 调整plugins中的配置，指定JSON文件的存放目录和报告输出路径：

plugins: [{
  package: require.resolve('protractor-multiple-cucumber-html-reporter-plugin'),
  options: {
    automaticallyGenerateReport: true,
    removeExistingJsonReportFile: true,
    openReportInBrowser: true,
    jsonOutputPath: './reports/json/', // 指定JSON文件的存放目录
    reportPath: './reports/html/', // 报告输出目录
    pageTitle: "Project Report",
    pageFooter: "<div><p>Protractor with cucumber</p></div>",
    customData: {
        title: 'Offer Creation UI test report',
        data: [
            { label: 'Project', value: 'Eternals UI Automation' },
            { label: 'Created By', value: 'Drashti Gadhia' }
        ]
    }
  }
}],

3. 修正报告目录的拼写错误 #

你当前代码中存在目录名拼写错误：TestExecutinReport应为TestExecutionReport，如果继续使用原逻辑，需要修正该拼写，否则会导致报告生成失败。

4. 移除冗余的afterLaunch合并逻辑 #

由于protractor-multiple-cucumber-html-reporter-plugin会自动合并所有JSON文件生成统一报告，因此可以移除afterLaunch中的手动合并HTML代码，避免重复操作。
