foundation tests
by Rob Stryker
Hi All:
I'm a little curious why there's a need for the number of test plugins
in foundation. Currently I see
org.jboss.tools.foundation.checkup.test
org.jboss.tools.foundation.core.test
org.jboss.tools.foundation.help.test
However, checkup and help are both 1 or 2 classes in the entire plugin,
and neither one of them seem likely to require additional tests. Why
were these tests added to their own plugin?
I'm asking because I'd like to add some new UI tests, and I think adding
a 4th plugin seems a bit ridiculous. Wouldn't it make more sense to just
have a foundation.core.test and a foundation.ui.test, and move the
checkup and help tests into whichever makes more sense?

Holy cow. Thanks for the help, all. Zimbra's presented me with quite the sea of... quotation-al soup.
Not sure if I'm doing the jbosstools-dev mailing list right. Here goes...:

Thanks for your suggestion, Paul.
At what point am I guaranteed that there is an active workbench window?
Is it necessary to poll the workbench to see when it's active? Is it likely that plugins crash otherwise?

Thanks for your response, Denis.

I'm not entirely certain that Bundle is an ancestor of the class I'm referring to.
The listener appears to be registered successfully when the plugin is run,
and it only has this problem in the context of SWTBot testing.

Thanks for the link. The plugin also targets Eclipse 3 platforms, but I'll take a look at this nevertheless

This is the PR that adds in the listener, and everything listener like:

Thanks for your response, Max.

This is indeed something I'm doing right now. However, the UiPlugin seems to have a pattern of
registering/unregistering listeners/services on start/stop. I'm hesitant to break that pattern.

I'll need to do a bit more reading on this one in order to see if it's a feasible solution.
The selection listener seems to be fairly general. I'm still taking the time to understand its purpose
and what the best solution is. For reference, this shows the earlier state of the code: https://github.com/eclipse/buildship/pull/120/files

I'm looking at this solution now. Is there any chance that the 'BundleActivator.stop()' method (the method that unregisters the listener, if it hasn't already been unregistered) could be invoked before the 'earlyStartup' method?
