使用量角器 webdriver-manager 运行一项任务后，Grunt 停止答案

【问题描述】：

我目前正在尝试将一些 Protractor E2E 测试与 grunt 联系起来。到目前为止，还没有那么成功。我能找到的所有文件都说 grunt 应该适合我的情况。但是，在运行webdriver-manager update --standalone 之后，grunt 会退出而不会出现错误消息或运行任何其他任务。

我的 Gruntfile：

'use strict';

module.exports = function(grunt) {

  grunt.initConfig({

    pkg: grunt.file.readJSON('package.json'),
    protractor: {
      options: {
        configFile: "./conf.js", // Default config file 
        keepAlive: true, // If false, the grunt process stops when the test fails. 
        noColor: false, // If true, protractor will not use colors in its output. 
        args: {
          // Arguments passed to the command 
        }
      },
      all: {}   // Grunt requires at least one target to run so you can simply put 'all: {}' here too. 
    },

    protractor_webdriver: {

    update : {
        options: {
          path:'node_modules/.bin/',
          command: ['webdriver-manager update --standalone']
        },
      },
      e2eStart: {
        options: {
          keepAlive: true,
          path:'node_modules/.bin/',
          command: ['webdriver-manager start']
        },
      },
    }
  });

  grunt.registerTask('default', ['protractor_webdriver:update', 'protractor_webdriver:e2eStart', 'protractor:all']);
  grunt.loadNpmTasks('grunt-protractor-webdriver');
  grunt.loadNpmTasks('grunt-protractor-runner');


};

因为可能有人好奇：packages.json

{
  "name": "Protractor-me",
  "description": "Protractor-me!",
  "version": "0.0.1",
  "devDependencies": {
    "grunt": "^0.4.5",
    "grunt-protractor-runner": "~2.0.0",
    "grunt-protractor-webdriver": "~0.2.0",
    "jasmine-reporters": "^2.0.7"
  },
  "install": {}
}

最后，grunt --verbose 输出

$

它运行 webdriver-manager 更新，然后停止。我的理解是每个任务都应该按顺序运行，并且在它结束或出错之前不会停止。我没有主意了！

【解决方案1】：

您可以尝试创建一个调用多个任务的自定义任务，如下所示：

grunt.registerTask('foo', 'My "foo" task.', function() {
// Enqueue "bar" and "baz" tasks, to run after "foo" finishes, in-order.
grunt.task.run('bar', 'baz');
// Or:
grunt.task.run(['bar', 'baz']);
});
