当我在 protractor-cucumber 中运行步骤定义文件时，浏览器没有捕获给定的 url

德芙丽娜

我是这个量角器黄瓜的新手。如果我出错了，请纠正我。我在运行功能文件时使用量角器 3.2.2，它给出了正确的输出。但是当我运行步骤定义时，浏览器不采用给定的 url。

我的功能文件如下。

Feature: Login page test   
Scenario: Verify whether the user is able to view the login page while 
giving the URL.   
Given I go to "http://localhost:4200/login"       
When The URL of the page should be "http://localhost:4200/login"

我的步骤定义文件如下。

var chai = require('chai');
var chaiAsPromised = require('chai-as-promised');

chai.use(chaiAsPromised);
var expect = chai.expect;

module.exports = function() {

this.Given('I go to {string}', function (string) {
browser.get(string);
});
this.When('The URL of the page should be {string}', function (string) {
expect(browser.getCurrentUrl()).to.eventually.equal(string);
});
}

我的配置。文件如下

exports.config = {
seleniumAddress: 'http://127.0.0.1:4444/wd/hub', 
allScriptsTimeout: 11000,
specs: [ 
'features/*.feature'    
],  
capabilities: {  
'browserName': 'chrome'    
},  
directConnect: true,  
baseUrl: 'http://localhost:4200/login',
framework: 'custom',
frameworkPath: require.resolve('protractor-cucumber-framework'),

cucumberOpts: {  
require: 'features/step_definitions/*.js',   
tags: false,
format: 'pretty',
profile: false,
'no-source': true
}  };

下面给出了当我运行 'protractor protractor.conf.js' 时显示的错误。

从错误信息：Error: ECONNREFUSED connect ECONNREFUSED 127.0.0.1:54206,

您的问题应该是由于使用较低的 chromedriver 和较高的 Chrome 浏览器引起的，升级 chromedriver 应该可以解决您的问题。

并在您的配置文件中更改cucumberOpts，如下所示：

cucumberOpts: {
    monochrome: true,
    strict: true,
    plugin: ["pretty"],
    require: [
        'features/step_definitions/*.js'
    ],
    tags: ''
}

更改您的步骤定义文件如下：（如果您使用 Cucumber 1 或以下）

var chai = require('chai');
var chaiAsPromised = require('chai-as-promised');

chai.use(chaiAsPromised);
var expect = chai.expect;

module.exports = function() {

    this.Given('I go to "(.*?)"', function (url) {
        browser.get(url);
    });

    this.When('The URL of the page should be "(.*?)"', function (url) {
        expect(browser.getCurrentUrl()).to.eventually.equal(url);
    });

};

如下更改您的步骤定义文件（如果您使用 Cucumber 2 或更高版本）

var {defineSupportCode} = require('cucumber');

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

    Given('I go to "(.*?)"', function (url) {
        browser.get(url);
    });

    When('The URL of the page should be "(.*?)"', function (url) {
        expect(browser.getCurrentUrl()).to.eventually.equal(url);
    });
});
