Example: if a ‘foo’ has 3 ‘bars’,

bars\_count == “0” # ERROR  
bars.count == 3 # OK

It looks like a bug to me.

And what about collection.size and collection\_count? Which should be  
used  
and in what case?

It looks like a bug to me.

I should have added that I use a count cache on the “foo” table.  
=\> there is a “bars\_count” column in the ‘foo’ table,  
BUT  
I didn’t initialize it, as the bars are added in another fixture:  
bars.yml

=\> my test class starts with  
fixture :foos, :bars

It looks like counters caches are not initialized by fixtures.
