Cucumber JS 示例在我的本地系统中不起作用

Question

我正在尝试在我的本地 windows 系统中执行 cucumber-js 示例程序 http://cucumber.github.io/cucumber-js/，

节点版本 0.10.26 npm 版本 1.4.3

文件夹结构

../node_modules ../test/features/support/world.js ../test/features/new_math.js ../test/features/step_definitions/demonstrationSteps.js

//steps code
module.exports = function () {
this.World = require("../support/world").World;

this.Given(/^a variable set to (\d+)$/, function(number) {
  this.setTo(number);
});

this.When(/^I increment the variable by (\d+)$/, function(number) {
  this.incrementBy(number);
});

this.Then(/^the variable should contain (\d+)$/, function(number) {
  if (this.variable != parseInt(number))
    throw new Error('Variable should contain ' + number +
      ' but it contains ' + this.variable + '.');
});
};

世界档案：

var CustomWorld = function() {};

CustomWorld.prototype.variable = 0;

CustomWorld.prototype.setTo = function(number) {
  this.variable = parseInt(number);
};

CustomWorld.prototype.incrementBy = function(number) {
  this.variable += parseInt(number);
};

module.exports.World = CustomWorld;

专题文件：

Feature: Simple maths
  In order to do maths
  As a developer
  I want to increment variables

  Scenario: easy maths
    Given a variable set to 1
    When I increment the variable by 1
    Then the variable should contain 2

  Scenario Outline: much more complex stuff
    Given a variable set to <var>
    When I increment the variable by <increment>
    Then the variable should contain <result>

    Examples:
      | var | increment | result |
      | 100 |         5 |    105 |
      |  99 |      1234 |   1333 |
      |  12 |         5 |     18 |

当我执行命令时 "cucumber-js /test/features/new_math.feature" 以下是我在命令提示符中得到的输出。

Answer 1

我找到了解决方法，我配置了 package.json 来触发脚本

  "scripts": {
    "test": "cucumber-js test/features/demonstration.feature"
  },

所以当我使用命令时"npm test"。正在执行这些功能。
