        }
    }
}

新建start.js（此文件為啟動(dòng)文件，所以可以隨意命名）

require('nightwatch/bin/runner.js')

自此涩澡，環(huán)境搭建完畢顽耳。可以寫(xiě)測(cè)試用例
我們新建一個(gè)tests文件夾存儲(chǔ)測(cè)試用例妙同。新建一個(gè)./tests/test.js

module.exports = {
    'Search by baidu': function (client) {
        // 定義頁(yè)面元素
        const searchInput = '#kw';
        const searchBtn = '#su';
        const resultContainer = '#container';
        // 啟動(dòng)瀏覽器并打開(kāi)www.baidu.com
        client.url('http://baidu.com').maximizeWindow()
            // 確保輸入框可以使用.
            .waitForElementVisible(searchInput, 5000)
            // 輸入"nightwatch"然后搜索.
            .setValue(searchInput, 'nightwatch')
            .click(searchBtn)
            .waitForElementVisible(resultContainer, 1000)
            // 截屏 
            .saveScreenshot('reports/answers.png')
            .end()
    }
}

相信這個(gè)用例大家都看得懂射富。
然后終端輸入

node ./start.js

效果如下（簡(jiǎn)書(shū)對(duì)GIF大小有限制，就截了部分）：

改裝

上面我們是事先下載好selenium driver與jar包粥帚。其實(shí)我們可以使用selenium-standalone這個(gè)安裝器(需要翻墻)
首先安裝依賴(lài)

nom install --save-dev selenium-standalone

其次胰耗，新建selenium文件夾。在此文件夾下新建selenium-conf.js

const process = require('process')
module.exports = {
    // selenium版本與下載地址
    // check for more recent versions of selenium here:
    // https://selenium-release.storage.googleapis.com/index.html
    version: '3.7.1',
    baseURL: 'https://selenium-release.storage.googleapis.com',
    // Driver看情況配置芒涡，比如只需要chrome就止血chrome 即可
    drivers: {
        chrome: {
            // check for more recent versions of chrome driver here:
            // https://chromedriver.storage.googleapis.com/index.html
            version: '2.33.2',
            arch: process.arch,
            baseURL: 'https://chromedriver.storage.googleapis.com'
        },
        ie: {
            // check for more recent versions of internet explorer driver here:
            // https://selenium-release.storage.googleapis.com/index.html
            version: '3.0.1',
            arch: process.arch,
            baseURL: 'https://selenium-release.storage.googleapis.com'
        }
    }
}

新建setup.js文件

const selenium = require('selenium-standalone')
const seleniumConfig = require('./selenium-conf.js')
// 從網(wǎng)絡(luò)下載selenium
selenium.install({
    version: seleniumConfig.version,
    baseURL: seleniumConfig.baseURL,
    drivers: seleniumConfig.drivers,
    logger: function (message) { console.log(message) },
    progressCb: function (totalLength, progressLength, chunkLength) { }
}, function (err) {
    if (err) throw new Error(`Selenium 安裝錯(cuò)誤: ${err}`)
    console.log('Selenium 安裝完成.')
})

運(yùn)行setup.js即可安裝

node ./selenium/setup.js

大坑

為什么是大坑呢柴灯？因?yàn)槔戏騁oogle卖漫，逛了好些國(guó)外論壇，看了源碼都沒(méi)搞定下面這貨弛槐。

坑

"chrome": {
    "desiredCapabilities": {
        "browserName": "chrome",
        "chromeOptions": {
            "args": [
                "disable-web-security",
                "ignore-certificate-errors"
            ]
        }
    }
}

發(fā)現(xiàn)還真可以消除這個(gè)ignore-certificate-errors，但是卻不能打開(kāi)網(wǎng)頁(yè)酸舍。
百般無(wú)奈之下帅韧，看源碼，定位到

selenium.js

打印this.cliOpts參數(shù)可見(jiàn)

參數(shù)

后記

有空寫(xiě)個(gè)selenium Java時(shí)遇到的一些問(wèn)題以及解法叮阅。比如滾動(dòng)截屏的Javashi xian
