此问题原因：没有配置环境变量

此问题解决方法：

设置TestNG的环境

设置TESTNG_HOME环境变量指向TestNG的jar 存放在您的机器上的基本目录位置。假设，我们已经储存了testng-6.8.jar， TestNG各种操作系统上的文件夹如下：

OS	输出
Windows	Set the environment variable TESTNG_HOME to C:\TESTNG
Linux	export TESTNG_HOME=/usr/local/TESTNG
Mac	export TESTNG_HOME=/Library/TESTNG

设置CLASSPATH变量

设置CLASSPATH环境变量指向TestNG的jar文件位置。假设，我们已经储存了testng-6.8.jar, TestNG在各种操作系统上的文件夹如下：

OS	输出
Windows	设置环境变量 CLASSPATH 为 %CLASSPATH%;%TESTNG_HOME%\testng-6.8.jar;
Linux	export CLASSPATH=$CLASSPATH:$TESTNG_HOME/testng-6.8.jar:
Mac	export CLASSPATH=$CLASSPATH:$TESTNG_HOME/testng-6.8.jar:
