Hi Kevin (and everyone else)! Attached are `spec.hpp' which implements the inital supported BDD terms (equal, not_equal, between(...)and(...) ). On 9/15/06, Kevin Wheatley <hxpro@cinesite.co.uk> wrote:
I think I agree that the should.equal() part may be better expressed at equals() (Law of Demeter style) but its context specific, so perhaps a wider interface is called for to improve the expressiveness.
I've been thinking about it, but unless I find a (better) way to be able to offer different specifications based on different subjects: there's value(...), object(...), pointer(...) then "should" will remain. (Please see attached files) Unless the following is possible: template <typename _T> struct value { explicit value(const _T & value) : _value(value) { }; const _T & value; // ... implement equals(), does_not_equal(), etc. etc. }; And be able to use `value' in the following use case: int i = 0; value(i).equals(0); And leverage automatic type deduction for type parameters (which I'm not sure is even possible)... I'm sticking with "should" for the meantime. :D
My end point would be that a BDD framework would be helpful if it could provide a wide enough set of expressions to allow the users to interact with the developers in an improved way.
I've attached the initial explorations (one header, and a test implementation). Comments and insights will be most appreciated. :)

As to the ghostly reference, it was for a visual effect for a film and the request came from an artist to a developer, in this case it was important that the two work directly to express the requirements and not have 2-3 layers of interpretation between them. "make it look ghostly" might be the name of a test suite or behavioral description suite/acceptance tests essentially a starting point for ubiquitous language.
Very interesting indeed. I would think BDD will be very useful in these situations, especially for the developers and even non-technical customers (who feel comfortable with english anyway). -- Dean Michael C.
