环境变量
如果已经配置好了环境变量，在终端（Terminal）输入echo $JAVA_HOME，echo $PATH，echo $CLASSPATH，里面包含正确的JDK路径，那就可以跳过这一步。
JAVA_HOME：指向JDK的安装目录；
PATH：指定命令搜索路径，设置好path变量后，就可以在任何目录下执行javac/java等工具了；
CLASSPATH：指定类搜索路径。
~ jihan$ java -version
java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode)
~ jihan$ /usr/libexec/java_home -V
Matching Java Virtual Machines (1):
1.8.0_211, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home
/Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home
vim .bash_profile 配置环境变量
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home
PATH=$JAVA_HOME/bin:$PATH:.
CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.
export JAVA_HOME
export PATH
export CLASSPATH
在终端中输入source ~/.bash_profile，使这个文件立即生效。
测试是否生效
~ jihan$ echo $CLASSPATH
/Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home/lib/tools.jar:/Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home/lib/dt.jar:.
~ jihan$ echo $PATH
/Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home/bin
~ jihan$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home

================================================================================
Don‘t use GUI mode for load testing !, only for Test creation and Test debugging.
For load testing, use CLI Mode (was NON GUI):
jmeter -n -t [jmx file] -l [results file] -e -o [Path to web report folder]
& increase Java Heap to meet your test requirements:
Modify current env variable HEAP="-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m" in the jmeter batch file
Check : https://jmeter.apache.org/usermanual/best-practices.html
