Exception in thread "main" java.lang.NoClassDefFoundError: junit/framework/Test

[arundev]

Hi,

I use eclipse ide and selenium rc.
When i export the TestSuite as jar i am getting the following
exceptions.
Exception in thread "main" java.lang.NoClassDefFoundError: junit/
framework/Test
at
com.selftechy.testsuite.commonBrowser.main(commonBrowser.java:46)
Caused by: java.lang.ClassNotFoundException: junit.framework.Test

----------------------------------------------------------------------------------------------------
My test Suite code:-
---------------------------------
package com.selftechy.testsuite;
import junit.framework.Test;
import junit.framework.TestSuite;
public class RunTestSuite {

public static Test suite() {
TestSuite suite = new TestSuite();
suite.addTestSuite(Test1.class);
suite.addTestSuite(Test2.class);
suite.addTestSuite(Test3.class);
suite.addTestSuite(Test4.class);
return suite;
}

public static void main(String[] args) {
junit.textui.TestRunner.run(suite());
}
}

The code works fine in eclips and ANT.

Thanks
Arun Dev

show us the command line you ise to execute this.

the cause for such thing usually ahs to with the fact that the jar file is not in the classpath where the JVM looks up for classes.

in other words you have to tell the JVM where to look when loading classes.

ex:

java -cp "c:\file1.jar;cL\file2.jar" com.my.class.with.main.method

referance

(My knowledge in java is very limitted)

Thanks in advance

You are confusing yourself with the approach here.

java -jar ----> This essentially ignores any classpath settings and just proceeds with finding everything within the jar that you are providing.

java -cp ---> If this form is used, you would specify all the jars that are to be referred by java as ";" separated (In Windows)/ ":" (In Non Windows) and then provide the class that contains the main() method so that Java can invoke it. Alternatively if your jar "myjar.jar" in this case, has a manifest file (which is some thing like a meta data file, which will contain information pertaining to what is the class that needs to be invoked to run the main method) you can skip specifying the class name that contains the main method which you want to be invoked.

For e.g., selenium-server-standalone-2.18.0.jar has a manifest file under META-INF folder as defined below

Manifest-Version: 1.0

Ant-Version: Apache Ant 1.8.1

Created-By: 1.6.0-google-v4-55908-24403953 (Sun Microsystems Inc.)

Main-Class: org.openqa.grid.selenium.GridLauncher

Name: Build-Info

Selenium-Version: 2.18.0

Selenium-Revision: 15704

Selenium-Build-Time: 2012-01-27 15:48:16

So here if you see, we are telling java that it needs to by default invoke the main() method that resides within org.openqa.grid.selenium.GridLauncher

Disclaimer : This is all based on my limited understanding of how things work :)
