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

[Chris Daley <chebizarro gmail com>]

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.

https://esite.ch/2012/06/writing-tests-for-vala/

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