UnknownError：連接被拒絕（連接被拒絕）

我正在MEAN JS棧應用程序中運行一個grunt測試，發現一個問題，我無法解決它的原因。UnknownError：連接被拒絕（連接被拒絕）

自己運行webdriver-manager，即webdriver-manager start，工作正常，但通過咕嚕聲test任務運行似乎失敗。

我也注意到端口是不同的（不是4444）。不知道如何改變這一點。

Aborted due to warnings.

這是tests.js的配置（/config/assets/tests.js）：

'use strict'; 

module.exports = { 
    tests: { 
    // client: ['modules/*/tests/client/**/*.js'], 
    client: ['modules/forum/tests/client/**/*.js'], 


    // server: ['modules/*/tests/server/**/*.js'], 
    server: ['modules/forum/tests/server/**/*.js'], 

    e2e: ['modules/*/tests/e2e/**/*.js'] 
    // e2e: ['modules/forum/tests/e2e/**/*.js'] 

    } 
};

我還發現，量角器的config.json，/node_module/protractor/config.json下有此配置：

{ 
    "webdriverVersions": { 
     "selenium": "2.47.1", 
     "chromedriver": "2.19", 
     "iedriver": "2.47.0" 
    } 
}

這是我自己的protractor.config.js，位於網絡應用程序的根目錄中：

'use strict'; 

// Protractor configuration 
var config = { 
    specs: ['modules/*/tests/e2e/*.js'] 
}; 

if (process.env.TRAVIS) { 
    config.capabilities = { 
     browserName: 'firefox' 
    }; 
} 

exports.config = config;

這裏是量角器的NPM描述符（/node_module/protractor/package.json）：

請添加您的配置文件。 – cnishina

@cnishina - 我已經添加了測試配置的片段。那是你需要的配置嗎？ – dcpartners

我很困惑。這不是一個量角器配置文件。你在使用量角器5嗎？你在使用包裝量角器的東西嗎？ – cnishina

這裏是一個發生了什麼事我最好的猜測：

  1. 您與硒獨立服務器locally使用這個IP發動地址和端口不是4444.這意味着您沒有選擇seleniumAddress: "http://localhost:4444/wd/hub"或directConnect: true。我會看到下面的代碼片段。

  2. 如果您在本地啓動而不是在特拉維斯上，則量角器將啓動Chrome browser by default。這也意味着你應該已經下載了ChromeDriver。

  3. 您應該從Protractor 2.5升級到最新版本。量角器與整個堆棧緊密耦合：selenium-webdriver，獨立服務器，瀏覽器驅動程序和瀏覽器。如果您使用的是最新的瀏覽器和Protractor 2.5，那麼可能是webdriver-manager下載了可能與您的瀏覽器不兼容的舊二進制文件。

這裏是代碼片段：

exports.config = { 
    // option 1. launches a selenium standalone server. this is helpful if 
    // you launch it with "webdriver-manager start" 
    // seleniumAddress: "http://localhost:4444/wd/hub", 
    // 
    // option 2. launch browser directly using browser binaries 
    // directConnect: true, 
    // 
    // option 3. do not include either seleniumAddress or directConnect 
    // and this option will launch the selenium standalone server using 
    // your ip address. 
    // 
    // option 4: launch with saucelabs or browserstack options 
}

該文件涉及到這一塊，你定義你的配置，集功能僅適用於特拉維斯和導出配置。

'use strict'; 

// Protractor configuration 
var config = { 
    specs: ['modules/*/tests/e2e/*.js'] 
}; 

if (process.env.TRAVIS) { 
    config.capabilities = { 
    browserName: 'firefox' 
    }; 
} 

exports.config = config;

編輯protractor.config.js並在不同的控制檯上運行'webdriver-manager start'。它很好地工作！ var config = {seleniumAddress：'http：// localhost：4444/wd/hub'， specs：['modules/*/tests/e2e/*。js'] }; – dcpartners

Huzzah！好的一點是你需要在不同的控制檯上運行'webdriver-manager start'。 – cnishina
