JUnit: 4.8.1 "Could not find class"

Question

Well, I, like others, are new to jUnit and have a hard time trying to get it to work. I searched the forum, but the answers are provided; I just do not understand. If anyone there could lend me a hand, I would really appreciate it.

Let me outline the basics: OS: Mac OS X.6

export JUNIT_HOME="/Developer/junit/junit4.8.1" export CVSROOT="/opt/cvsroot" export PATH="/usr/local/bin:/usr/local/sbin:/usr/localmysql/bin:/opt/PalmSDK/Current/bin/:/usr/local/mysql/bin:$PATH:$JUNIT_HOME:$CVSROOT" export CLASSPATH="$CLASSPATH:$JUNIT_HOME/junit-4.8.1.jar:$JUNIT_HOME" 

I can compile a test class from a java file, however, when I try to run a test

 java org.junit.runner.JUnitCore MyTest.class 

I get the following:

 JUnit version 4.8.1 Could not find class: MyTest.class Time: 0.001 OK (0 tests) 

Now I was in the directory with MyTest.class , which is located somewhere in my file system, I tried to move the source folder to the junit folder and the junit/junit4.8.1 and the same result. I can't even run the tests that came with junit.

Answer 1

Is MyTest in the package by default? If not, then you need to give the full name corresponding to the package. In other words, if MyClass has an operator

 package com.myself; 

and lives in

 /myproject/src/com/myself/MyClass.java 

and you compiled into

 /myproject/classes 

then /myproject/classes should be on your CLASSPATH , and you should

 java org.junit.runner.JUnitCore com.myself.MyTest 

Think about it, now I see that you are adding .class to the class name, so even if it's in the default package, you should just say

 java org.junit.runner.JUnitCore MyTest 

Answer 2

Remove .class from MyTest.class, i.e. java org.junit.runner.JUnitCore MyTest

Answer 3

We have no problem finding JUnit - it's finding. It cannot find MyClass, so the directory of this class (given its absence in packaging) should be on the way to the classes.
