Re: Open Test-File as Document to test CompletionProvider

I guess you are missing a dependency or a registration of projectmanager
implementation.

Have a look how other projecttypes are tested. F.e.
https://github.com/radimk/nbgradle/blob/master/core/src/test/java/org/nbgradle/netbeans/project/GradleProjectFactoryTest.java

With kind regards, markiewb
