JUnit Test

[Kalyani Nayak]

I am new to JUnit testing.
I am using Eclipse3.1 IDE.
I have created a test java application.
I have included junit.jar in my class libraries of java project.
I followed all the steps to create a JUnit test program as-

right clicking my java application >new->other->JUnit->JUnit Test Case

I am trying to run a junit test case, but it is giving error.
It is popping up a error message as -

"Fatal Exception occured.Program will exit."

And on console of eclipse it is showing an error as-

java.lang.NoSuchMethodError: junit.framework.TestCase.getName()Ljava/lang/String;
at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.getTestName(RemoteTestRunner.java:710)
at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.sendTree(RemoteTestRunner.java:655)
at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.sendTree(RemoteTestRunner.java:643)
at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:471)
at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:344)
at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196)
Exception in thread "main"


Please can anybody give solution to it?
My Junit test program is like-

package myPackage;

import junit.framework.*;
import junit.textui.TestRunner;


public class MyTest1 extends TestCase {
public static void main(String[] args) {
junit.textui.TestRunner.run(MyTest1.class);
}
public MyTest1 (String name) {
super (name);
}
public void testFirst() {
System.out.println("Hello in Junit test");
}
public void testSecond(){
try{
System.out.println("In running test method:");
}catch(Exception e){

}
}
}

Sounds like you are using an old version of JUnit. Get the newest one and try again. (You won't need the constructor any more.)

I am having the same problem with Eclipse 3.1.1., and I am using Ant 3.8.1. Any other ideas?

[Rich Reese]

When I remove the contstructor I get the following error:

java.lang.AbstractMethodError: org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.addFailure(Ljunit/framework/Test;Ljava/lang/Throwable V
at junit.framework.TestResult.addFailure(TestResult.java:112)

What do you mean by "other ideas"? Did you check the version of *JUnit* you are using? The AbstractMethodError points into the same direction: somewhere there is an incompatible version of the junit.jar on the classpath.

[Rich Reese]

Sorry, I meant I am using JUnit 3.8.1 and not Ant 3.8.1. I will check my classpath to see if I have another version on the class path.

[Rich Reese]

I checked my classpath and I don't see anything of concern. Doesn't ecplise use th Junit version specified in the Eclipses Target Platform -> Plugins under the Window -> Preferences menu option?

[Kamal Ahmed]

right click on prject, and include junit as external jar

[Rich Reese]

That didn't work either.

[Lasse Koskela]

Could you post the contents of the ".classpath" file from your project's root directory?

[Rich Reese]

Here you go...

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="conf"/>
<classpathentry kind="src" path="doc"/>
<classpathentry kind="src" path="dtd"/>

<classpathentry kind="src" path="webapp"/>

<classpathentry kind="lib" path="lib/castor-0.9.5-xml.jar"/>

</classpath>

[Kamal Ahmed]

My .classpath looks like:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry kind="con" path="org.eclipse.pde.core.requiredPlugins"/>
<classpathentry kind="lib" path="C:/logging-log4j-1.2.13/dist/lib/log4j-1.2.13.jar"/>
<classpathentry kind="lib" path="C:/junit3.8.1/junit.jar"/>
<classpathentry kind="output" path="classes"/>
</classpath>

as compared to yours

My Junit test program is like-

 
package myPackage;
 
import junit.framework.*;
 
 
public class MyTest1 extends TestCase 
{
   public void testFirst() 
   {
      System.out.println("Hello in Junit test");
   } 
 
   public void testSecond()
   {
      System.out.println("In running test method:");
   }
}

You don't need the main or the ctor, just the test methods. All that other stuff is old school, from previous versions.

Which version of JUnit are you running? Should be 3.8.1

This one looks suspicious. What does it contain?

I added the Junit.jar to the class path but it still doesn't work. I have the other jars in there because my app needs them to compile.

<classpathentry kind="src" path="doc"/>
<classpathentry kind="src" path="dtd"/>

If I remove the constructor, I get the following error message from eclipse.

Implicit super constructor TestCase() is undefined for default constructor. Must define an explicit constructor DateRangeFiltrationRuleTest.java

[Kamal Ahmed]

you need to write asserts, like assertEquals(); and assertTrue(); etc
look at junit API for more information, also look at some junit examples, or buy the book "Unit Testing in Java" By Johannes Link

Hope that helps

[Lasse Koskela]

Rich, I'd probably go through each of those .jar files in your .classpath file and grep them (or whatever you'd use for that on Windows if that's what you're running) for "TestCase.class". I suspect that one of those .jar files contains an old version of JUnit.

Alternatively, you might want to move up junit.jar on your project's classpath so that its JUnit classes are "preferred" over anything that's found within the other .jar files.

[Rich Reese]

Hallelujah!!! It finally works. So the steps I took was the following:

1.) Added the junit.jar to my project classpath
2.) Moved the junit.jar to the top of my classpath before any other jar
files.

Thanks for all of your help. I was about to go crazy. One thing that confuses me though is that I didn't think the jre could evaluate the contents of a jar file if it is embedded within another jar file.

Thanks again,
Rich

That's true. The only possible explanation is that one of those other jar files actually contains the junit class files directly. I still suspect the third-party.jar.
