[Vala] Any xUnit framework for Vala?

[Anatol Pomozov <anatol pomozov gmail com>]

Hi,

I am trying to add some tests to my application and I am looking for
an example of Vala application with tests.

As an Java developer I would expect that Vala has some xUnit like
framework http://en.wikipedia.org/wiki/XUnit but seems there is
nothing like this. There is also Glib Testing framework, but I cannot
find any examples for Vala as well.

What is "State of the Art" Vala application with unittests? I see that
Vala project itself does some magic with testwrapper.sh, is it
preferred solution?
