测试文档

这个文档记录 EasyServer 相关的测试结果，包括：

  1. 功能测试
  2. 性能测试
  3. 内存检查

以下将按照上述分类对测试结果进行分析记录。

功能测试

功能测试目前主要分为如下几个部分：

  1. 线程池测试
  2. 同步日志测试
  3. 异步日志测试
  4. 服务器功能测试

线程池测试 test_ThreadPool

线程池线程数设置为8，任务数量设置为1e6。运行 test_ThreadPool，结果如下：

RUN THREADPOOL FUNCTION TEST
Thread 139932610426624 executed 126945 tasks.
Thread 139932627212032 executed 126791 tasks.

Thread 139932635604736 executed 119959 tasks.
total tasks : 1000000, Cost time : 5198000000ms

线程池功能正常。

同步日志测试 test_synLog

日志数量设置为 1e6 * 5，文件分割大小设置为 200 Mb，结果如下：

SynLogger cost time = 44139 ms

生成的日志文件如下：

同步日志功能正常。

异步日志测试

日志数量设置为 1e6 * 5，文件分割大小设置为 500 Mb，结果如下：

AsynLogger cost time = 19768 ms

生成的日志文件如下：

├── test-AsynLog-20220719-220555.EasyTencentCloud.23095.log
├── test-AsynLog-20220719-220600.EasyTencentCloud.23095.log

├── test-AsynLog-20220719-220611.EasyTencentCloud.23095.log

异步日志功能正常。

服务器功能测试

本处仅测试服务的 get 功能，在运行目录下放置了一个简单的 index.html。更复杂的功能测试可以使用提供的文件运行 server，使用浏览器进行测试。

首先运行 server，测试时设置端口号为1316，server 的工作线程数设置为 4，然后进行测试，结果如下：

1:
strlen(p) = 1
n=-1

2:
strlen(p) = 13
n=247
HTTP/1.1 404 Not Found
Connection: close
Content-type: text/html
Server: EasyServer
Content-length: 136

<html><title>QAQ EASY NOT EASY</title><body bgcolor="ffffff">404 : Not Found
<p>File Not Found</p><hr><em>EasyServer</em>
</body></html>

3:
strlen(p) = 113
n=113
HTTP/1.1 200 OK
Connection: close
Content-type: text/html
Server: EasyServer
Content-length: 10

TEST PAGE

测试阶段生成的日志如下：

可以看到，服务器功能正常。

CTest

最后使用 CTest 整体进行测试，结果如下：

测试通过。

性能测试

测试环境为腾讯云轻量级应用服务器，配置为 4 核 4 GB 内存，但是由于服务器上还运行了其他任务，可能无法完全发挥性能，只作为参考。

EasyServer 的运行参数设置为8个工作线程，开启异步日志。

使用的测试工具为 WebBench，由于性能限制，并发连接总数设置为 8000，连接时间设置为 5s。测试运行命令如下：

webbench -c 8000 -t 5 http://127.0.0.1:1316/index.html

测试结果如下：

./webbench -c 8000 -t 5 http://127.0.0.1:1316/
Webbench - Simple Web Benchmark 1.5
Copyright (c) Radim Kolar 1997-2004, GPL Open Source Software.

Benchmarking: GET http://127.0.0.1:1316/
8000 clients, running 5 sec.

Speed=1411620 pages/min, 5599473 bytes/sec.
Requests: 117635 susceed, 0 failed.

可知在测试机上 EasyServer 的 QPS 可以达到 20000+。

测试结果仅供参考。

内存检查

内存检查部分，使用 Valgrind 的 memcheck 工具对 EasyServer 的相关功能进行检查。检查代码使用功能测试中编写的代码。

Valgrind 的参数设置为：

--tool=memcheck --leak-check=full --show-reachable=yes --trace-children=yes

线程池 test_ThreadPool

线程池线程数设置为8，任务数量设置为1e7，结果如下：

$ valgrind --tool=memcheck --leak-check=full --show-reachable=yes --trace-children=yes ./build/bin/test_ThreadPool

可以看到线程池测试中并无内存泄漏的情况出现。

同步日志 test_synLog

生产的同步日志数量设置为 1e5 * 5，测试结果如下：

$ valgrind --tool=memcheck --leak-check=full --show-reachable=yes --trace-children=yes ./build/bin/test_syncLog
==3912== Memcheck, a memory error detector

可以看到同步日志测试中无内存泄漏的情况出现。

异步日志 test_asynLog

生产的异步日志数量设置为 1e5 * 5，测试结果如下：

$ valgrind --tool=memcheck --leak-check=full --show-reachable=yes --trace-children=yes ./build/bin/test_asynLog 
==5620== Memcheck, a memory error detector

==5620== For lists of detected and suppressed errors, rerun with: -s
==5620== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)

可以看到异步日志测试中无内存泄漏的情况出现。

服务器 tese_server
