headless swtbot does not find testproject [message #495908]

I tested on Mac OS X and on windows. Both tests works when I start them from inside Eclipse, not from CLI (or Ant).
To test in Eclipse I start org.eclipsecon.swtbot.example.AllTests as swtbot Test.

I followed the headless screencast and http://wiki.eclipse.org/SWTBot/Ant#Executing, but I don't really understand why.
On OSX it crashes with a SIGTRAP caused bylibswt-cocoa-carbon-3452.jnilib, I think that's maybe a problem from Apple's implementation.
On windows I get an error that the Test class was not found [1].

The commands I used on windows:

set ECLIPSE_HOME=D:\eclipse_saros
set TEST_CLASS=org.eclipsecon.swtbot.example.AllTests
set CLASSPATH=%ECLIPSE_HOME%\plugins\org.eclipse.equinox.launche r_1.0.101.R34x_v20081125.jar;D:\tmp\foo_workspace\org.eclips econ.swtbot.example\bin;%ECLIPSE_HOME%\plugins\org.eclipseco n.swtbot.example_1.0.0.jar

The class is not found because of a class cast exception. Loading of the
class byte code itself failed in this case. Perhaps you have a mismatch
of junit versions.

Did you delete the junit4 (or junit3) fragments supplied by swtbot as
described in the setup section of the wiki ? Do you have the
'org.eclipse.ant.optional.junit' fragment in your workspace ?

I delete org.junit_3.8.2.* from plaugins folder and now it runs.
I thought it was not necessary, because on http://wiki.eclipse.org/SWTBot/Ant it was not mentioned. There is said only to use *.swtbot.*.junit4 (or 3).

I don't have 'org.eclipse.ant.optional.junit' on my workspace, do I need it?

Thanks and greets Sandor.

Sandor, I agree that we should add this in wiki page
http://wiki.eclipse.org/SWTBot/Ant
Some people get the same trouble for several times.

Ketan, We may change Setup section like this,

Setup

Your folder structure should look like the following:

ECLIPSE_HOME
+ plugins
| - com.yourplugins
| - ...
| - ...
| - org.eclipse.swtbot.swt.finder
| - org.eclipse.swtbot.eclipse.finder
| - org.hamcrest (and other dependencies)
| - ...
| - ...
| - org.eclipse.swtbot.ant.optional.junit4 (or junit3, but not both) (from the Headless Testing Framework)
| - org.eclipse.swtbot.eclipse.junit4.headless (or junit3.headless, but not both) (from the Headless Testing Framework)
| - org.junit4 (or org.junit, but not both)
+ features

Do you agree on this change?

Best Regards

Yes, we will be going to OSI, Mars, and Pluto, but not necessarily in

I have exactly the same ClassCastException.

But I can't remove junit 3.8.2 from my Eclipse plugins directory, because it's used by other plugins.

And I don't get it why I have to remove it. I thougt this is the big deal with OSGI that you can have plugins in different versions in your plugin directory. And your Manifest defines the right version for your plugin.

Do you make some Classloader hacks in SWTBot or why is it necessary?

Kind regards
Tino

This is still a show stopper for me. Any ideas how to solve this problem without removing junit3 or junit4 from the plugins directory?

Thanks for your help.

You need not delete the junit 3.8.2 plugin from your plugins directory.
See the SWTBot Troubleshooting guide on how to fix this[1].
