JUnit: 4.8.1 "Could not find class"

Question

Ok, I am like other and new to jUnit and having a difficult time trying to get it working. I have searched the forum but the answers provided; I am just not getting. If anyone out there could lend me a hand I would greatly appreciate it. Let me provide 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 then run the 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 have been in the directory with the `MyTest.class` which is just somewhere in my file system, I tried moving the source folder to the `junit` folder and the `junit/junit4.…

Accepted Answer

Is `MyTest` really in the default package? If not, then you need to give the entire package-qualified name. In other words, if MyClass has a statement

```
package com.myself;
```

and lives in

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

and you compiled into

```
/myproject/classes
```

then `/myproject/classes` must be on your `CLASSPATH` and you must

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

Come to think of it, I see now that you're appending `.class` to the class name, so even if it's in the default package, you should just say

```
java org.junit.runner.JUnitCore MyTest
```
