我有路径：

%JUNIT_HOME%\junit-4.12

添加到Path。和系统变量

JUNIT_HOME | C:\JUNIT\

Answer 1

看起来你在运行命令中缺少类路径。

What is a classpath in java

在Windows中

将环境变量CLASSPATH设置为

 %CLASSPATH%;%JUNIT_HOME%\junit4.12.jar;.;

Linux的

export CLASSPATH = $CLASSPATH:$JUNIT_HOME/junit4.12.jar:.

的Mac

export CLASSPATH = $CLASSPATH:$JUNIT_HOME/junit4.12.jar:.

开始使用JUnit
