[swtbot-dev] SWTWorkbenchBot.closeAllShells()

[Xavier Raynaud <xavier.raynaud@xxxxxxxxx>]

Hi,

I found a strange issue with SWTBot, and I would like to know if you can 
reproduce or explain it.
I use SWTBot-2.1.1 on linux, with eclipse kepler.

At the beginning of a test, I call "SWTWorkbenchBot.closeAllShells()".
Theoretically, this method closes all shell but the Eclipse one (I 
experimentally verified that the Eclipse shell is not closed). Am I right ?

Unfortunately, after this call, a lot of subsequent workbench operations 
(such as perspective switching, opening a view, closing a view, ...) are 
throwing exceptions similar to the following one:

---------------------------

---------------------------

If I remove "SWTWorkbenchBot.closeAllShells()" statement, all goes well.



By the way, I would like to warmly thank you for this great project.
We have deployed SWTBot with jacoco in continuous integration for our 
product (Kalray produces a massively parallel embedded device, with more 
that 256 processors, and uses Eclipse as IDE).
Thanks to SWTBot, we are able to deploy complex test scenarios, such as 
remote debugging of multi-platform applications (running on both x86 and 
our parallel device).
I do not know if you have a "testimonial" section in your project, but 
I'm OK to write one if you want !
