Crank 是微软新出的一个性能测试框架，集成了多种基准测试工具，如bombardier、wrk等。 Crank通过统一的配置，可以转换成不同基准测试工具命令进行测试。可参考Bombardier Job实现。 安装Crank运行如下两个命令分别安装 dotnet tool update Microsoft.Crank.Controller --version "0.2.0-*" --global dotnet tool update Microsoft.Crank.Agent--version "0.2.0-*" --global
安装完成后执行命令
PS C:\Users\Stack\Desktop> crank

-?|-h|--help Show help information
-c|--config Configuration file or url
-s|--scenario Scenario to execute
-j|--job Name of job to define
--profile Profile name
--script Execute a named script available in the configuration files. Can be used multiple times.
-j|--json Saves the results as json in the specified file.
--csv Saves the results as csv in the specified file.
--compare An optional filename to compare the results to. Can be used multiple times.
--variable Variable
--sql Connection string of the SQL Server Database to store results in
--table Table name of the SQL Database to store results in
--session A logical identifier to group related jobs.
--description A string describing the job.
-p|--property Some custom key/value that will be added to the results, .e.g. --property arch=arm --property
os=linux
