如何运行 chrome 的多个实例以在量角器中按单个功能文件的顺序运行所有场景

Question

我希望所有场景都在多个浏览器实例中运行，我尝试提供最大实例功能，但它总是打开 1 个 chrome 实例并一一运行测试。我希望测试在多个 chrome 实例中运行。我在这里做错了什么？

当前配置文件：

     exports.config = {
      allScriptsTimeout: 800000,
      getPageTimeout: 400000,
      specs: [
        './src/cucumber/features/**/memberSearch.feature',
      ],
      params: {
        pageObjects: require['./src/cucumber/pages/**/*.po.ts'],
        customTimeout: 5000,
        url:{
          dev: "https://dev.com/login",
          test: "https://test.com/login",
          stage: "https://stage.com/login",
          local: "http://localhost:4200",
        }
      },
      capabilities: {
        browserName: 'chrome',
        //acceptInsecureCerts: true,
        shardTestFiles: true,
        maxInstances: 4,
        chromeOptions: {
          args: ['--no-sandbox', '--disable-setuid-sandbox', '--disable-gpu', '--window-size=800x600'],
        },
      },
  directConnect: true,
  baseUrl: 'https://dev.com/',
  useAllAngular2AppRoots: true,
  framework: 'custom',
  frameworkPath: require.resolve('protractor-cucumber-framework'),
  cucumberOpts: {
    compiler: 'ts:ts-node/register',
    require: ['./src/cucumber/steps/**/*.steps.ts', './src/cucumber/utils/**/*.util.ts'],
    format: 'json:./reports/cucumber_report.json',
    monochrome: true,
    strict: true,
    tags: '@MemberSearch',
  }

功能文件：

    @MemberSearch
Feature: Search a member
  @CompletedTodo
  Scenario: See all the assessments associated with the member
    Given Enter the URL
    When  click on the MemberID radio Button
    And   Type the memberID "ABCD" first time
    And   Click the Search Button first time
  
@FilterTitle
  Scenario: Validate the Filters With Title field
    Given Enter the URL
    When  click on the MemberID radio Button
    And   Type the memberID "ABCD"
    Then  Click the Search Button
  
@FilterTimeFrame30
 Scenario: Validate the Filters with time FilterTimeFrame 30
   Given Enter the URL
    When  click on the MemberID radio Button
    And   Type the memberID "ABCD"
    Then  Click the Search Button
    Then  Show the message "No records to display"
  
@FilterTimeFrame60
 Scenario: Validate the Filters with time FilterTimeFrame 60
   Given Enter the URL
    When  click on the MemberID radio Button
    And   Type the memberID "ABCD"
    Then  Click the Search Button
  
@FilterTimeFrame90
 Scenario: Validate the Filters with time FilterTimeFrame 90
   Given Enter the URL
    When  click on the MemberID radio Button
    And   Type the memberID "ABCD"
    Then  Click the Search Button
    Then  Show the message "No records to display"
    And   Click the Clear Button
  
@FilterTimeFrame365
 Scenario: Validate the Filters with time FilterTimeFrame 365
   Given Enter the URL
    When  click on the MemberID radio Button
    And   Type the memberID "ABCD"
    Then  Click the Search Button
    Then  Show the message "No records to display"
    And   Click the Clear Button
    When  Type the memberID "40988"

您可以尝试在 npm/protractor 脚本中使用“--parallel=**”（例如：cucumber-js ./features --parallel=5）。将 ** 替换为您需要的并行实例数。配置文件中的'maxInstances'是指浏览器应该启动的最大实例数，并不意味着默认打开4个实例，根据--parallel count进行更改。

--parallel in cucumber-js 运行同一个特性文件的每个场景，一个场景大纲的每个示例并行触发。
