Hi,

I am new to SWTBot. I just got it up and running on my environment a
couple of days ago. However, when I try to execute the sample SWTBot Test
for eclipse plugins from the user's guide, it gives me the following
error, after the eclipse workbench gets launched:

I would be extremely glad if I get any help to get this problem solved.

Thanks,
Bhooshan.

If you are new to SWTBot I suggest to use a new SWTBot version. You seem
to be using a very old one, v.1.2.

The new version is 2.0 (still not finished) and the package names start
with "org.eclipse" instead of "net.sf".

If you then still have a errors, we can look at it, but I think it is
difficult to analyse errors for an old SWTBot version.

Hi Hans,

Thanks for your reply. I downloaded swtbot v2.0, but it shows me the same
error as before. Only this time, the path for the class
SWTBOTEclipseTestCase (which had the NoClassDefFound before) is different.

The error with v2.0:

@Ketan: Can you please look into it too?

@Bhooshan:
Verify that you have no compile errors in Eclipse (I assume you start it
from IDE). You need the SWTBot plugins in your target platform and in your
Eclipse plugins directory.

I have never tried that example from the user's guide, so I don't know
about it specifically. But such tests work, since SWTBot internally uses
such tests too when building new versions.

Alternatively you can check out all the sources of SWTBot and build it by
yourself using it's "releng" plugin. There is a readme file in that
plugin. If you do what is written then you can build SWTBot and see all
it's tests running.

Hi folks,

Sorry for the delay in responding. I managed to get swtbot to run with the
eclipse environment on my machine over the last week using some local
help. I also managed to write some testcases and it is working just fine.
Thanks a lot for the help.

I am trying to use SWTBot to automate our products installer. The
installer is built on eclipse/swt (The name of the installer is IBM
Installation Manager), so I would think SWTBot supports it. However, I am
not sure how to set up and run the application so it can be automated.
The SWTBot docs say to launch the Main() method in it's own thread, but we
have no access to the source code.. I only have the .exe. Am I supposed
to launch it using Java Runtime/Java Process? Any advice would be very
helpful.

Thanks,
Bhooshan

Can you please help on how to execute an SWTBot testcase?
