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

Question

我是 cucumberjs 的新手，只是尝试我第一次尝试运行一项功能。我已经构建了cucumber-js github page 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，我希望获得有关 cucumber 的文档 这样我就可以专注于构建出色的应用程序

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：5000 毫秒后步骤超时 在 Timer.listOnTimeout (timers.js:92:15) 当我转到 README 文件时 #StepDefinitions/myStepDefinition.js:15 然后我应该看到“Usage”作为页面标题# StepDefinitions/myStepDefinition.js:22

失败场景：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

鉴于它是 cucumber-js github 页面上的示例功能，因此可能不会不正确，如何尝试使此功能通过？

所有代码如下：

    // 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));
    }
  });
};

特点：

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;
};

添加这个以删除 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;

示例：

test.feature

Feature: test
    I want test wait

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

ma​​in.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;

Answer 2

在我的例子中，我不得不在 defineSupportCode 中设置默认超时，因为尝试在 webdriver 中修改超时并没有提供任何效果

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

    setDefaultTimeout(60 * 1000);

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

Refer to this part of the doc

将步骤定义中的this.Given 替换为promise 使用的语法，是在两个不同的OSX 环境中为我修复它的原因。

这是有效的承诺语法：

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.
});
