### Question:
FormEditorPresenter extends KieEditor<FormModelerContent> { public void onLockStatusChange(@Observes UpdatedLockStatusEvent updatedLockStatusEvent) { if (updatedLockStatusEvent.getFile().equals(versionRecordManager.getCurrentPath())) { if (updatedLockStatusEvent.isLocked() && !updatedLockStatusEvent.isLockedByCurrentUser()) { layoutEditor.lock(); } else { layoutEditor.unlock(); } } } @Inject  FormEditorPresenter(FormEditorView view,
                               ChangesNotificationDisplayer changesNotificationDisplayer,
                               FormDefinitionResourceType resourceType,
                               Caller<FormEditorService> editorService,

@Test public void testOnLockStatusChange() { loadContent(); FormEditorPresenter presenterSpy = spy(presenter); UpdatedLockStatusEvent updatedLockStatusEvent = new UpdatedLockStatusEvent(versionRecordManager.getCurrentPath(), true,false); presenterSpy.onLockStatusChange(updatedLockStatusEvent); verify(layoutEditorMock).lock(); updatedLockStatusEvent = new UpdatedLockStatusEvent(versionRecordManager.getCurrentPath(), false, false); presenterSpy.onLockStatusChange(updatedLockStatusEvent); verify(layoutEditorMock).unlock(); }
