 More precisely, because you didn't initialize the library. IMPLEMENT_APP
macro is not the only way to do it, you can also use wxInitialize and
wxUninitialize functions. Be warned that currently things don't work if
you try to initialize the library after shutting it down (this is something
we'd like to fix and would welcome any contributions towards it but didn't
have time to do it ourselves yet).

 The tests in tests subdirectory do use CppUnit, however they don't use any
widgets. I am not really sure how do you intend to test widgets with
CppUnit anyhow to be honest. The wxSwTesting framework already mentioned in
this thread should be a better choice for this.
