[ruby-gnome2-devel-en] test unit

[Detlef R. <det...@gm...>]

Hi,

for a gtk application I use Test::Unit for tests of the internal 
functionality of self made widgets. This worked very well for a long 
time. But now, with adding further tests it fails.

I have two tests for the same widget class, each with several 
assertions. The widget is created in the "setup" method and in the tests 
only methods of the widget are called. The second test fails with the 
following message:

Error: test_Foobla_view_do_undo__0(TestFooblaView): RuntimeError: ruby 
wrapper for this GObject* already exists.
/home/det/.gem/ruby/2.3.0/gems/gobject-introspection-3.0.9/lib/gobject-introspection/loader.rb:307:in

The failing call in the widgets implementation is:
@pointerWriteMark = Gdk::Cursor.new :xterm

it is called in the widgets initialize method.

Do I have to do some kind of clean up on the Gtk/Gdk level between 
tests? Other ideas?
