Mark Dexter persistence tutorial Junit problems

[sonny]

i've just started the second tutorial in the Mark Dexter eclipse tutorials
and having a problem with using Junit 4.
I cant get it to work with Junit 4

my AllTest class worked fine with Junit 3
so as directed i have changed the syntax of the class file thus:

package org.persistence.tutorial;

import org.junit.runner.*;
import org.junit.runners.*;
 

@RunWith(Suite.class)
@Suite.SuiteClasses(value={
		BookTest.class,
		PersonTest.class,
		MyLibraryTest.class,
		
})

public class AllTests {
	
	}

i added Junit 4 source files to the build path ( although quick fix wouldnt do this for me, i had to do it manually.

Then i opened the run configurations dialogue and selected Junit 4 as the test runner.

but it will not run the test i get a list of console output. see below.

I cant understand what I have missed. I have followed the instructions to the letter.. excepting that quickfix would not automatically add junit 4 to the buildpath for me. I had to do it manually.

could this be something to do with using Stanford Universities version of Eclipse. i am currently running Version: 3.4.2 of eclipse

here is the console output i get when i try to run the all test class.

java.lang.SecurityException: class "junit.framework.JUnit4TestCaseFacade"'s signer information does not match signer information of other classes in the same package

Yeah, I think that could very well be. I've never used the Stanford version of Eclipse, which means I had some issues with the Stanford exercise code when I was doing them, but I had no problems with the Mark Dexter tutorials.

I cant get it to work with Junit 4

make sure the j4unit library is include in eclipse like in the following pic



if not, try to add your j4unit...jar into your classpath from eclipse. you can also try to create a new test-source-folder for junit4 tests.

[sonny]

okay the Junit4 icon and the JRE system library never appear in package explorer,
they have never appeared there. I noticed this in the first tutorials but no issues arose as a result of them not being there.

i checked again that Junit 4 is in the build path, and it is.
but i removed it any way, rebooted eclipse and put it back again.
i deleted the AllTest class and and opened a new Junit test case in the test subfolder.
eclipse automatically checked the Junit 4 options and I wrote the class again from scratch.
still got loads of red console output and no test.

I checked around a few other things, but :confused:
heres a screen shot of the libraries on my build path.
it looks kid of right to me, but to be honest i dont know if it is or not.

Jeez, can't you upload a smaller screenshot please, have merci. ;-)

try this: right-click your persistence project, choose Build Path -> Configure Build Path and then select Libraries and delete the package for JUnit 3 from your project class path.

it does enlarge if you click on it ;-)

cool that seems to have worked. it works fine now :)

thanks j2me64

My mother told me not to click on anybody else's thumbnails; humble and obedient as I am I never do that.

kindest regards,

Jos ;-)

All my Mum told me was not to bite mine.
I should do well to remember your mother's advice in future
