Thanks for your answer David, but I think there is a problem.
The assertion that fails has nothing to do with the BidDecimal types,
but with the created_at and updated_at timestamps
I have try this:
v = Factory.create(:my_object)
f = MyObject.first
v.should == f ==> This fails
v.amount.should == f.amount ==> This works
But...
v.updated_at.should == f.updated_at
