@Siedlerchr When I run this test, I get the error:
Cannot invoke "org.jabref.preferences.JabRefPreferences.getFilePreferences()" because "org.jabref.gui.Globals.prefs" is null
This is because line 84 in ExportToClipboardAction, it is calling:
Exporter defaultChoice = exporters.stream() .filter(exporter -> exporter.getName().equals(Globals.prefs.getImportExportPreferences().getLastExportExtension())) .findAny() .orElse(null);
I know we should not depend on Globals or alter the value of Globals.prefs in unit tests, but I was just trying if making Globals.prefs not null would solve the problem and it did. In this situation, how should we get arround this error the right way?
Thanks,
Ning

Hi, as you cannot mock the Globals away, the only solution is to refactor the ExportToClipBoardAction, extend the constructor with an additional argument for PreferenceServices. As this is a bit more complicated, I just did this to show you how to do this if you encouter this again.
Edit// Can you enable https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/allowing-changes-to-a-pull-request-branch-created-from-a-fork#enabling-repository-maintainer-permissions-on-existing-pull-requests
