superagent.get(‘www.baidu.com’).redirects(0)

如果要测试的系统都是HTTPS，需要取得信任证书，并导出来（浏览器登录https的时候会要求接受证书，这个过程中可以导出来），以备模拟登录时使用。superagent使用证书简单示例，假设已准备好的证书文件为abc.pem：

process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';var cert = fs.readFileSync(__dirname + '/abc.pem');
superagent.get('https://abc.com').ca(cert).end(function(err, res) {...});

注意node.js里面一定要设置 process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0'; 才能成功。

function request(httpReq, testData) { //httpReq代表一个http; testData主要是设置对http response进行校验的黑白名单等等return new Promise(function(resolve) {var assert = require('./assertion.js').assert, //引入自己开发的assertion模块对http reponse进行校验endpoint = httpReq.req_endpoint,req_method = httpReq.req_method.toLowerCase(),req_headers = httpReq.req_headers,req_body = httpReq.req_body;superagent[req_method](endpoint).set(req_headers).send(req_body).timeout(10000).end(function(err, res) {var result = assert(httpReq, res, testData);resolve(result);});});
}

var superagent = require('superagent');function execute(httj, testData) { //httj是所有解析出来的http对象集合; testData是为需要的http设置的黑白名单等校验条件var failureCount = 0,logs = [];if (testData.serial) { //串行var p = Promise.resolve();for (var key in httj) {void function(k) {p = p.then(function(result) {log(result);return request(httj[k], testData); //request函数简单包装了superagent执行HTTP的方法，见上一段示例代码
                });}(key);}p.then(function(result) {log(result);});} else { //并行var allWS = [];for (key in httj) {allWS.push(request(httj[key], testData));}p = Promise.all(allWS).then(function(arr) {for (var result of arr) {log(result);}});}return p.then(function() {var isPassed, report;failureCount === 0 ? isPassed = true : isPassed = false;report = logs.sort().join('');return { //生成最终测试结果
            isPassed,report};});function log(result) {if (result !== undefined) {if (result.status === 'failed') {++failureCount;}logs.push(result.info);}}
}

function search(obj, key) {var arr = [];for (var i in obj) {if (!obj.hasOwnProperty(i)) continue; //exclude properties from __proto__if (i === key) {var o = new Object;o[i] = obj[i];arr.push(o);}if (typeof obj[i] === 'object') {arr = arr.concat(search(obj[i], key));}}return arr;
}

"assertion_criteria": {"baidu.com/home/display": {"whitelist": ["<title>Home</title>", "name", "货币"]},"baidu.com/search": {"blacklist": ["pageInfo", "id", "时间戳"]}
}

function flatten(obj) {var arr = [];if(obj instanceof Array) {obj.forEach(function(element) {if(typeof element!=='object') {arr.push('ROOT:' + element);} else {arr = arr.concat(flatten(element));}});} else {for(var key in obj) {if(!obj.hasOwnProperty(key)) continue;if(typeof obj[key]!=='object') {arr.push(key + ':' + obj[key]);} else {if(obj[key] instanceof Array) {obj[key].forEach(function(element) {if(typeof element==='object') {arr = arr.concat(flatten(element));} else {arr.push(key + ':' + element);}});} else {arr = arr.concat(flatten(obj[key]));}}}}arr.sort();return arr;
}

把http reponse经过上述黑白名单、扁平化处理后，就可以使用chai库进行字符串或者json对象比较（chai的eql或者contain方法），判断结果是否一致。这里就不贴代码了。
