A revolution in many small steps maybe, but I agree its not a quantum

One of the key ideas behind the BDD is that its trying to work around
the image that the word 'test' has out in the world of programming at
large. In a technical sense it isn't really all that different.

However when you introduce the idea of customers writing the
specification along with the developers you need a common language
between the two, and thats where the DSL bit comes in.

As an example I was at the Google Test Automation conference last week
and there was an interesting presentation where once the 'punctuation'
characters were removed (changed colour to white in the IDE) the tests
read in English sentences that a business analyst would have been able
to write.

Admittedly if your in the business of writing frameworks where your
customer is a developer this has less of a win. Its not really any
different to some of the clever language/syntax hacks found in the
Boost libraries.

I'll take any productivity gain I can get, especially if its near zero
cost :-)
