在近期工作规划中，分布式压测框架提上日程，目前「FunTester」已经具备了一些分布式压测中用到的功能。
例如在执行用例端：利用反射根据方法名执行方法的使用示例、命令行如何执行jar包里面的方法；或者在用例编写端：如何统一接口测试的功能、自动化和性能测试用例、如何在Linux命令行界面愉快进行性能测试；亦或前段时间探索的Groovy反射执行问题：反射执行Groovy类方法NoSuchMethodException解答、Groovy反射invokeMethod传参实践。
目前看已经有了几种粗略的性能测试用例方案，有一些已经进行了实践，有一些已经被我放弃了。分享出来，算是个梳理。
这里的测试用例方案分为两类：「用例传递」和「用例执行」。目前我的想法还是通过「HTTP」协议接口完成用例的传递和执行中控制。采用定时任务或者脚本轮询的方式进行执行的控制。目前来看肯定是一个Springboot项目了，这都是后话了。
下面分享第一种设想：
基于HttpRequestBase对象的压测场景
这种测试场景应该说非常少了，基于单个或者多个固定的HttpRequestBase对象的分布式压测方案，其实实现起来有点大材小用了。简单的请求，没有参数化规则，没有上下游接口调用，没有前置后置处理，缺乏链路功能支持。说了这么多缺点，下面分享基于HttpRequestBase对象的优点：实现简单，用例传递非常好做。执行起来也直接可以使用框架提供的能力。兼容性好，可以直接从功能用例中提取部分用例然后执行，达到用例多用的目的。
实现Demo
这里需要区分用例来源。一般来讲，编写单个用例肯定绕不开一张图：
HttpRequestBase
总体分成三部分：「请求行」、「请求头」和「请求体」。依照之前分享过的案例，将一个HttpRequestBase对象拆成三分部。例如我们获取一个请求的方式如下：
public static void main(String[] args) throws UnsupportedEncodingException {
HttpPost httpPost = getHttpPost("http://localhost:12345/test/qps");
httpPost.addHeader(getHeader("token", "324u2u09uweidlxnvldfsad"));
httpPost.setEntity(new StringEntity(getJson("name=FunTester").toString(), DEFAULT_CHARSET));
}
不过这样不利于HttpRequestBase对象在「HTTP」接口中传递，毕竟没有直接用「序列化和反序列化」的方法。所以我自己写了一个中间对象。
最开始的想法用fastJSON实现：
public static void main(String[] args) {
HttpPost httpPost = getHttpPost("http://localhost:12345/test/qps");
httpPost.addHeader(getHeader("token", "324u2u09uweidlxnvldfsad"));
httpPost.setEntity(new StringEntity(getJson("name=FunTester").toString(), DEFAULT_CHARSET));
httpPost.addHeader(HttpClientConstant.ContentType_JSON);
JSONObject httpResponse = getHttpResponse(httpPost);
output(httpResponse);
String s = JSON.toJSONString(httpPost);
HttpPost httpPost1 = JSON.parseObject(s, httpPost.getClass());
JSONObject httpResponse1 = getHttpResponse(httpPost1);
output(httpResponse1);
}
测试结果如下：

请求发生错误，其实这里面POST请求实体拷贝会失败。所以这个方法行不通了，只能换一个自己实现的。
public static void main(String[] args) {
HttpPost httpPost = getHttpPost("http://localhost:12345/post");
httpPost.addHeader(getHeader("token", "324u2u09uweidlxnvldfsad"));
httpPost.setEntity(new StringEntity(getJson("name=FunTester").toString(), DEFAULT_CHARSET));
httpPost.addHeader(HttpClientConstant.ContentType_JSON);
JSONObject httpResponse = getHttpResponse(httpPost);
output(httpResponse);
FunRequest funRequest = FunRequest.initFromRequest(httpPost);
HttpRequestBase request = funRequest.getRequest();
JSONObject httpResponse1 = getHttpResponse(request);
output(httpResponse1);
String text = JSON.toJSONString(funRequest);
HttpRequestBase httpRequestBase = FunRequest.initFromString(text).getRequest();
JSONObject httpResponse2 = getHttpResponse(httpRequestBase);
output(httpResponse2);
}

用例创建
用例很简单，就是一个个的HttpRequestBase对象，这里用com.funtester.httpclient.FunRequest类作为中转。
代码生成FunRequest对象
代码语言：javascript复制 static FunRequest getCase001() {
HttpPost httpPost = getHttpPost("http://localhost:12345/post");
httpPost.addHeader(getHeader("token", "324u2u09uweidlxnvldfsad"));
httpPost.setEntity(new StringEntity(getJson("name=FunTester").toString(), DEFAULT_CHARSET));
httpPost.addHeader(HttpClientConstant.ContentType_JSON);
return FunRequest.initFromRequest(httpPost);
}
这样我们获取一个FunRequest对象即可。
字符串
这里分两种：一种是从代码里面创建FunRequest，用字符串信息保存。
static String getCase001() {
HttpPost httpPost = getHttpPost("http://localhost:12345/post");
httpPost.addHeader(getHeader("token", "324u2u09uweidlxnvldfsad"));
httpPost.setEntity(new StringEntity(getJson("name=FunTester").toString(), DEFAULT_CHARSET));
httpPost.addHeader(HttpClientConstant.ContentType_JSON);
FunRequest funRequest = FunRequest.initFromRequest(httpPost);
return JSON.toJSONString(funRequest);
}
第二种是原本就是字符串，或者数据库中一条记录，通过某种不可描述的方法转换成FunRequest对象。这里就分一下从字符串中读取FunRequest对象的方法，由于情况过于复杂，其他的情况我就不写了，各位有兴趣可以自己实现。
/**
* 从字符串中获取请求对象
* @param fun
* @return
*/
static FunRequest initFromString(String fun) {
def f = JSON.parseObject(fun)
RequestType requestType = RequestType.getInstance(f.requestType)
def request = new FunRequest(requestType)
request.host = f.host
request.path = f.path
request.uri = f.uri
request.args = f.args
request.json = f.json
request.params = f.params
f.headers.each {
request.addHeader(it.name,it.value)
}
request
}
用例传输
这个相对接简单多了。用例一旦转换成字符串之后，就可以通过接口上传到master服务，或者由master服务分配给salve服务（暂时Springboot方案）去执行。
上传用例
这里先写一个简单的POST接口上传用例的Demo。
static boolean updateCase() {
HttpPost httpPost = getHttpPost("http://localhost:12345/updatecase");
httpPost.addHeader(getHeader("token", "324u2u09uweidlxnvldfsad"));
JSONObject json = getJson("name=FunTester");
json.put("FunTester", getCase002());
json.put("各种参数", FunTester);
httpPost.setEntity(new StringEntity(json.toString(), DEFAULT_CHARSET));
httpPost.addHeader(HttpClientConstant.ContentType_JSON);
JSONObject httpResponse = getHttpResponse(httpPost);
return isRight(httpResponse);
}
分配用例
这里我目前是放弃Socket协议推送用例，而是让salve去master分配好的队列中取用例，当然这里的用例包含必要的运行信息，而不仅仅是一个FunRequest对象。
static JSONObject returnCase() {
JSONObject json = getJson("name=FunTester");
json.put("FunTester", getCase002());
json.put("各种参数", "FunTester");
return json;
}
用例执行
salve拿到用例之后，先去解析响应，然后通过构建多线程任务对象或者list，然后交付给执行框架去完成用例的执行和数据展示和记录。
- 这里我为了省事儿直接用
RequestThreadTimes模型做了Demo，其他三种暂时不赘述了。
单HttpRequestBase用例
相对简单，虽然可以通过组合多个性能用例来完成多个HttpRequestBase对象的性能压测，但是我非常不推荐这样，所以我在接下来的对象里面拒绝这种用例形式。
static void executeCase(CaseBase caseBase) {
FunRequest funRequest = caseBase.getFunRequest();
int thread = caseBase.getThread();
int times = caseBase.getTimes();
int runup = caseBase.getRunup();
String name = caseBase.getName();
RequestThreadTimes requestThreadTimes = new RequestThreadTimes(funRequest.getRequest(), times);
Concurrent concurrent = new Concurrent(requestThreadTimes, thread, name);
Constant.RUNUP_TIME = runup * 1.0;
concurrent.start();
}
多HttpRequestBase对象
这种用力的话，我采取的方案是caseBase对象中做一下区分，获取用例解析的时候解析成一个list，然后通过线程参数thread从头开始去list取FunRequest对象，构造多线程任务类RequestThreadTimes，完事儿之后交给执行框架执行。
static void executeCase(CaseBase caseBase) {
List<FunRequest> funRequests = caseBase.getFunRequests();
int thread = caseBase.getThread();
int times = caseBase.getTimes();
int runup = caseBase.getRunup();
String name = caseBase.getName();
List<ThreadBase> collect = range(thread).mapToObj(f -> new RequestThreadTimes(funRequests.get(f % funRequests.size()).getRequest(), times)).collect(Collectors.toList());
Concurrent concurrent = new Concurrent(collect, name);
Constant.RUNUP_TIME = runup * 1.0;
concurrent.start();
}
