Introduction

• GotyBench was designed for testing server load with multiple current threads

Currently we service only for HTTP Post request! Later we will add Get/Put Methods

Goal of GotyBench

1. Testing with multiple concurrency : Developed with goroutine lightweight multi-threaded, set to communicate through channels.
2. Automatically generate fuzzed json object : It is designed to automatically create a random json object when the user sets only the key and value type.
   • ex) "gotybench -j [userId,string,userAge,int]" : Set the value of userId to a random string. Also set the value of userAge to a random int.
3. Log server : By -s option, we can check all benchmark logs(http://localhost:8022)

Options

Option	Detail
-c	The number of concurrent thread
-h	See all options
-j	Generate fuzzed json object If you set the key/type of the json object with the corresponding option, a json object with a random value is created. Four types of fuzzing are supported as follows. int, float, string, boolean Usage Example ex) -j "[userId,string,userAge,int]"
-r	The number of HTTP Post request
-t	The timeout of the network connection of the benchmark client
-u	Request URL
-s	Access log server
-i	Add additional information

Before we started, we need to get ...

1. run go get github.com/fatih/color for coloring your terminal
2. run go get -v github.com/gosuri/uilive for updating process
3. run go get -u github.com/go-echarts/go-echarts/v2/... to see graph with responses in timeseries.
4. run go get github.com/ompluscator/dynamic-struct to dynamically add field of json structs.

Usage

1. run go run main.go in your terminal and see options

   Alloc = 0 MiB	TotalAlloc = 0 MiB	Sys = 8 MiB	NumGC = 0
   	Properties
   	- Max parallelism : 8
   Usage of /var/folders/h0/_d_zrr0j57x8wmknjb1r6hfm0000gn/T/go-build3252492082/b001/exe/main:
   -c int
   		스레드 개수 (default 100)
   -j string
   		Json "[KEY1,TYPE1,KEY2,TYPE2,...]" 
   -r int
   		요청 개수 (default 10000)
   -t int
   		요청 타임아웃(second) (default 30)
   -u string
   		URL

2. choose your options and run

Example

$ go run main.go -j "[userId,string,userPw,string,mail,string,userName,string]" -r 10000 -c 1000 -u http://127.0.0.1:8080/auth/user

 [Properties]
- Max parallelism : 8
- Request url : http://127.0.0.1:8080/auth/user
- The number of HTTP Requests : 10000
- The number of threads : 100
Listening server's response .. (10000/10000)

 [Results]
---------------------------------------------------------
| Response Status 	| Count 	| Percent 	|
| 200 			| 10000/10000 	| 100.0%	|
---------------------------------------------------------
- Average response time 	: 110.66 ms
- Max response time     	: 770.32 ms
- Min response time     	: 21.46 ms

 [Memory Usage]
- Heap size = 2 MB
- Cumulative Heap size = 161 MB
- All goroutine size = 22 MB
- GC cycle 횟수 = 48

Finished! ( Total Elapsed Time : 11.4659 seconds ) 
Now you can see response time series graph in local machine => http://localhost:8022
