Esteban,
good point. I use Tests sometimes as a mixture of design help and living
documentation. And there, test cases almost never match classes 1:1.
And I also think that is a good thing. Especially when it comes to
refactoring and major redesign where the API of some entry points to a
certain functional unit must not be changed.
One could now start a new discussion on whether this use case is "unit
testing" or now, but I guess we can be glad when people write any kind
of test ;-)
Not every thing that should be improved can be improved by changing
tools. Sometimes it really is a people thing.

I don't like having the Unit Tests so coupled with the code.
Many times I implement Unit Tests that doesn't match 1:1 with a class.
It is... the TestCase subclass doesn't have a corresponding class (eg.
SomeFeatureTest, with no SomeFeature class in the system).

I stumbled across this idea when Markus Gaelli chose it as a PhD topic about
ten years ago (man, I'm old). The main idea was not to provide tests, but
examples that happened to have assertions. The goal was twofold: (1) provide
live documentation with real objects, (2) provide another way of composing
tests.
The project did not really come to fruition, but I still think this is
highly interesting topic. Part of the ideas were later implemented in
Phexample (http://www.smalltalkhub.com/#!/~Phexample/Phexample/) and
JExample (http://scg.unibe.ch/research/jexample).

There was a presentation of the Pyret language at SCRIPT workshop last week.
This way of coupling unit tests with functions is indeed interesting.
One the one hand I feel it's like a mixing of concerns, on the other hand
it's push unit-tests into the language.
The funny part is that the examples provided are used to type the function:
fun id(x):
x
where:
id(3) is 3
id("bla") is "bla"
end
is typed as 'a -> 'a whereas:
fun id(x):
x
where:
id(3) is 3
end
is typed as int -> int

I have just come across the Pyret language. It looks interesting, but the
part which particularly caught my interest was the way that they had built
the unit tests directly into the classes, rather than having separate test
classes.
I think this is an interesting idea. It seems as though it would be easier
to manage writing tests if everything were in one location. And this - might
- mean that people were more likely to write tests.
Has anyone else looked at this, and have an opinion on whether it would be
a good addition to Pharo 4/5/X?
Cheers
Andy
