background
Before long, consider a stand-alone implementation capacity, pressure measurement work done using locust company SMS gateway, and later found a golang version of the locust, the performance version of python is 5 to ten times, but never had the chance to use.
Recently the company wanted to do a performance test platform, technology selection and development of the language requirement is consistent, that is golang, so I think a boomer, boomer record of using paper.
Environment Installation
Development environment | installation |
---|---|
Python 3.7 | slightly |
locust 0.11.0 | pip install locustio |
golang | slightly |
boomer | go get github.com/myzhan/boomer |
Note : The latest version of the boomer compatible goczmq, locust you need to upgrade to a higher version to complete compatibility.
Scripting

This part of the code is not important, as long as the start line.
