UnknownError：接続が拒否されました（接続が拒否されました）

Question

MEAN JSスタックアプリでgruntテストを実行していますが、その原因を解決できないという問題が見つかりました。

webdriver-managerを単独で実行しています（webdriver-manager start）。うまくいきますが、grunt testタスクを実行しているとエラーが発生しているようです。

また、ポートが異なっていることに気付きました（4444ではありません）。これを変更する方法もわかりません。

Aborted due to warnings. 

これはtests.jsための設定（/config/assets/tests.js）されています

'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'] 

    } 
}; 

私も/node_module/protractor/config.jsonの下で、その分度器のconfig.jsonを見つけましたが、この構成を有している：

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

そして、これウェブアプリケーションのルートにある自分のprotractor.config.jsです：

'use strict'; 

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

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

exports.config = config; 

そしてここで分度器のNPM記述子（/node_module/protractor/package.json）である：ここでは

Answer 1

は何が起こっているの私の最高の推測です：

1. あなたのIPアドレスを使用してセレンスタンドアロンサーバlocallyで起動していますこれは、seleniumAddress: "http://localhost:4444/wd/hub"またはdirectConnect: trueを選択しなかったことを意味します。私はこのように見えるコードスニペットを以下に示します。

2. トラベラーではなくローカルで起動している場合、投機器はChrome browser by defaultで起動します。これは、ChromeDriverをダウンロードしたはずであることを意味します。

3. 分度器2.5から最新のものにアップグレードする必要があります。分度器は、セレン - ウェブドライバ、スタンドアロンサーバー、ブラウザドライバ、ブラウザなど、スタック全体と強く結びついています。最新のブラウザと分度器2.5を使用している場合、おそらくwebdriver-managerがあなたのブラウザと互換性のない古いバイナリをダウンロードしたでしょう。ここで

コードスニペットです：

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 
} 

このファイルは、あなたが、あなたの設定を定義するだけでトラヴィスのための機能を設定し、設定をエクスポートし、この1つに関する。

'use strict'; 

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

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

exports.config = config;
