Not all tests can be singletons, If we cannot have tests singletons, how we suppose to test extension points?On 11/13/2013 09:25 AM, Denis Golovin wrote:
Cool.It is build.properties problems when not all resources from test plug-in are included into bundle jar. Should be fixed.
If you can avoid singletons, p2 will allow installation of multiple version of the same plugin. And you shouldn't see this error.That's because Foundation Tests is a singleton, and that you tried to run tests twice which caused to install the same bundle twice. p2 doesn't allow multiple version in same application.
2. Second try to run usually ends up with

If possible, remove the singleton directive from bundle. If not, then you need to use a clean application (which doesn't already contain the bundle) for every tests.
If I cannot change test an then run it again and again against the same product installation then there is no point to use this feature in development.
Should it be updating singleton instead of installing it? Would that help?
Otherwise, it means that you'll need either to uninstall previous version of the bundle, or run tests on a clean application everytime.
Singletons are only necessary when plugin define extension points or extensions. Bundle org.jboss.tools.foundation.test doesn't provide anything like that. Just get rid of the plugin.xml, remove the singleton directive in https://github.com/jbosstools/jbosstools-base/blob/master/foundation/tests/org.jboss.tools.foundation.core.test/META-INF/MANIFEST.MF#L4 , and p2 would allow several installations of the bundle so you'll be able to sequentially run tests on the same application without uninstalling anything.
Thx
Please open a bug against Tycho and add me in CC.
I'll do that.
