How good is the resolver part covered by tests?

[laeubi]

I currently have a problem with the resolver taking very long and not finding a suitable solution (> 20 minutes at very high CPU load) where as a last resort I need to kill the process forcefully.

My idea now is to add some debug output, recompile equinox and probably adjust some places. Of course I don't want to break the resolver and wonder if one runs the test + tck if this gives a good confidence everything "works like before"? Or are there any additional tests to perform (maybe at felix repository?).

The felix repository has very limited unit tests on resolver. I find the tests in the org.eclipse.osgi.tests.container.TestModuleContainer to be more complete. In full disclosure, when I make modifications to the felix resolver I do it first in Equinox and added tests there to TestModuleContainer and then "contribute" the fix back to felix at my leisure. I must admit I rarely added tests directly to felix resolver.
