Mixin / global function for assertThat

[Jonathan Lange]

People would like to use testtools matchers, but don't want to use testtools as a base class. At least, not yet. Providing a mixin would allow such people to start using testtools without paying a large migration cost.

It seems like you've had a discussion somewhere about this and captured the things some folk would like - thats great. However what seems to be missing is the things that concern them about inheriting from TestCase. If you know, could you capture that somewhere. If not, could you enquire?

At a guess it's not wanting to go even close to the nasty nest of multiple
inheritance – who knows what trial.TestCase and testtools.TestCase do
together? – but in any case I've forwarded the question to the originating
IRC channel.

And they've confirmed my guess.

I think this is done?

[Jonathan Lange (jml)]

Yes.
