CucumberJS - 错误:在Timer.listOnTimeout(timers.js:92:15)5000毫秒后步进超时

Question

我是cucjs的新手,只是尝试了第一次运行功能.我已经构建了在cucumber-js github页面上的功能.尝试运行时出现此错误:

Benjamins-MBP:功能Ben $ cucumber.js example.feature功能:示例功能

作为cucumber.js的用户,我希望有关于黄瓜的文档,以便我可以专注于构建真棒应用程序

场景:阅读文档#example.feature:6鉴于我在Cucumber.js GitHub存储库#StepDefinitions/myStepDefinition.js:4错误:在Timer.listOnTimeout(timers.js:92:15)5000毫秒后步进超时我转到README文件#StepDefinitions/myStepDefinition.js:15然后我应该看到"Usage"作为页面标题#StepDefinitions/myStepDefinition.js:22

失败的场景:example.feature:6#场景:阅读文档

1个场景(1个失败)3个步骤(1个失败,2个跳过)0m05.001s

如果它是在cucumber-js github页面上的示例功能,那么尝试使这个功能通过会怎么做,所以可能不正确？

这是所有代码:

    // features/step_definitions/myStepDefinitions.js

module.exports = function () {
  this.Given(/^I am on the Cucumber.js GitHub repository$/, function (callback) {
    // Express the regexp above with the code you wish you had.
    // `this` is set to a World instance.
    // i.e. you may use this.browser to execute the step:

    this.visit('https://github.com/cucumber/cucumber-js', callback);

    // The callback is passed to visit() so that when the job's finished, the next step can
    // be executed by Cucumber.
  });

  this.When(/^I go to the README file$/, function (callback) {
    // Express the regexp above with the code you wish you had. Call callback() at the end
    // of the step, or callback.pending() if the step is not yet implemented:

    callback.pending();
  });

  this.Then(/^I should see "(.*)" as the page title$/, function (title, callback) {
    // matching groups are passed as parameters to the step definition

    var pageTitle = this.browser.text('title');
    if (title === pageTitle) {
      callback();
    } else {
      callback(new Error("Expected to be on page with title " + title));
    }
  });
};

功能:

Feature: Example feature
  As a user of cucumber.js
  I want to have documentation on cucumber
  So that I can concentrate on building awesome applications

  Scenario: Reading documentation
    Given I am on the Cucumber.js GitHub repository
    When I go to the README file
    Then I should see "Usage" as the page title

world.js文件:

// features/support/world.js
var zombie = require('zombie');
function World() {
  this.browser = new zombie(); // this.browser will be available in step definitions

  this.visit = function (url, callback) {
    this.browser.visit(url, callback);
  };
}

module.exports = function() {
  this.World = World;
};

添加此项以删除5000毫秒:

protractor.conf.js

cucumberOpts: {
    require: [
        'tests/e2e/support/env.js',
        'main.step.js',
        ...
    ],
    format: 'pretty', // or summary
    keepAlive: false
},

env.js

var configure = function () {
    this.setDefaultTimeout(60 * 1000);
};

module.exports = configure;

例如:

test.feature

Feature: test
    I want test wait

    Scenario: Test call wait
        Given I wait "6" seconds

main.step.js

module.exports = function () {
    this.World = require(__base +'tests/e2e/support/world.js').World;

    // I wait "{time}" seconds
    this.Given(/^I wait "?([^"]*)"? seconds$/, function (time) {
        return browser.sleep(time * 1000);
    });

};

world.js

var World, chai, chaiAsPromised;

chai             = require('chai');
chai_as_promised = require('chai-as-promised');

World = function World (callback) {
    chai.use(chai_as_promised);

    this.expect = chai.expect;

    callback();
};

module.exports.World = World;

就我而言，我不得不在defineSupportCode 中设置默认超时，因为尝试修改 webdriver 中的超时没有提供任何效果

defineSupportCode(function({Given, When, Then, setDefaultTimeout}) {

    setDefaultTimeout(60 * 1000);

    Given('I am on the Cucumber.js GitHub repository', function() {

参考文档的这一部分

将步骤定义中的替换为 ,this.Given所使用的语法promise，这就是我在两个不同的 OSX 环境中修复它的原因。

这是有效的 Promise 语法：

this.Given(/^I am on the Cucumber.js GitHub repository$/, function () {
  // Notice how `callback` is omitted from the parameters
  return this.visit('https://github.com/cucumber/cucumber-js');

  // A promise, returned by zombie.js's `visit` method is returned to Cucumber.
});
