我使用Node.js、cucumber.js(全局安装)和Web Storm IDE，并使用了一个简单的加法场景，我得到了以下错误。步骤定义除了callback.pending之外没有其他内容。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$/, function (arg1, callback) {
callback.pending();
});
};
module.exports = myStepDefinitionsWrapper;
此错误
TypeError:无法读取World中未定义的属性"pending"。(/Users/wfn936/Repos/customer svc/features/step_definitions/customer.js:6:17)在。。。
当捕获的参数数量与提供的回调中的参数不匹配时发生
但在你的情况下，一切看起来都很好。
我建议你重新安装黄瓜(也许)再次检查您的功能和步骤定义文件
- 它们真的像你发布的吗
- 你使用这些文件吗(或者可能是其他带有其他内容的文件)
注意：
-
像
/^I have number (d+) and (d+)$/这样的Regexp必须具有回调function (arg1, arg2, callback) {} -
像
/^I have number (d+)$/这样的Regexp必须具有回调function (arg1, callback) {}
