Question

当我从命令提示符运行Gatling时，我得到一个这样的模拟列表：

选择模拟编号：1,2,3,4

当我键入3时，第三个模拟将运行但是这个序列是自动生成的。假设我想根据我的愿望列出它们： 3,2,1,4

是否可以为模拟列表提供用户定义的序列。如果有可能的话？

Answer 1

据我所知，Gatling不可能提供模拟序列。您可以通过编写例如bash脚本来实现此目的。要在mvn中运行Gatling测试，它可能看起来像这样

#!/bin/bash

#params
SIMULATION_CLASSES=

#usage
function usage (){
    echo "usage: $0 options"
    echo "This script run Gatling load tests"
    echo ""
    echo "OPTIONS:"
    echo "Run options:"
    echo "   -s             [*] Simulation classes (comma separated)"
}

#INIT PARAMS
while getopts “s:” OPTION
do
     case $OPTION in
     s) SIMULATION_CLASSES=$OPTARG;;
     ?) usage
        exit 1;;
     esac
done

#checks
if [[ -z $SIMULATION_CLASSES ]]; then
    usage
    exit 1
fi

#run scenarios
SIMULATION_CLASSES_ARRAY=($(echo $SIMULATION_CLASSES | tr "," "\n"))

for SIMULATION_CLASS in "${SIMULATION_CLASSES_ARRAY[@]}"
do
    echo "Run scenario for $SIMULATION_CLASS"
    mvn gatling:execute -Dgatling.simulationClass=$SIMULATION_CLASS
done

样本用法

./campaign.sh -s package.ScenarioClass1,package.ScenarioClass2

Answer 2

如果你使用Gatling SBT插件（demo project here），你可以用Bash做：

sbt "gatling:testOnly sims.ReadProd02Simulation" "gatling:testOnly sims.ReadProd02Simulation

首先只运行sceenario ReadProd02Simulation ，然后运行 ReadProd03Simulation 。不需要Bash脚本。

输出首先是ReadProd02Simulation和ReadProd03Simulation的输出，如下所示：

也就是说，首先它运行一个sim，然后运行另一个，并连接所有输出。

但你如何利用这个？好吧，你可以使用Bash和 grep 输出恰好两行匹配failed 0 ( 0%)（如果你运行两次模拟）+检查两次模拟的总请求数，也可以通过Bash + grep等

如何在序列中运行多个Gatling模拟（序列将由我们提供）
