Re: [Vala] Using TestCase class: assert (this is Object) fails in method, but not in constructor

[Steven Oliver <oliver steven gmail com>]

I'm in the process of implementing the gee test suite into my project. So far so good. The test suite was 
easy to figure out. So far my biggest problem has been trying to figure out how to setup CMake for it all to 
work. 

Thank you,
Steven N. Oliver

You may also find the Gee.TestCase class suits your needs - it certainly
makes the tests easier to read and is more xUnit like in its approach than
the 'naked' GLib Test classes.

Gives a good overview - and if I recall the GXml tests that Daniel
mentioned uses it as well.
