Question

我正在使用Node.js，cucumber.js（全局安装）和带有简单添加号码场景的Web Storm IDE，我收到以下错误。除了callback.pending之外，步骤定义没有其他任何内容。有什么想法吗？

Feature: As a math learner
  I want to add two numbers
  so that I can learn how to add

  Scenario:
    Given I have number 3 and 5
    When I add them
    Then I get 8 as result

var myStepDefinitionsWrapper = function () {
    this.Given(/^I have number (\d+) and (\d+)$/, function (arg1, arg2, callback) {
        callback.pending();
    });

    this.When(/^I add them$/, function (callback) {
        callback.pending();
    });

    this.Then(/^I get (\d+) as result$/, function (arg1, callback) {
        callback.pending();
    });
};
module.exports = myStepDefinitionsWrapper;

此错误

TypeError：无法在World处读取未定义的属性“待定”。（/Users/wfn936/Repos/customer-svc/features/step_definitions/customer.js:6:17）at ...

在捕获的args数与提供的回调中的args不匹配时发生

但在你的情况下，一切看起来都不错。

我建议你重新安装黄瓜（也许）再次检查您的功能和步骤定义文件

他们真的看起来像你发布了吗？
您使用这些文件（或可能是其他内容的其他文件）

注意：

/^I have number (\d+) and (\d+)$/等正则表达必须有回调function (arg1, arg2, callback) {}

/^I have number (\d+)$/等正则表达必须有回调function (arg1, callback) {}

Cucumber.js TypeError：无法读取未定义
