I think there's a blurring between the use of documentation and
specification here. Let me try to clarify a few things as to what BDD
wants to be able to achieve:

* Write Specification Suites for validating program behaviour :: In
lieu of calling these specification suites "test suites".

* Allow for writing programmatic specifications for systems,
subsystems, components, and "units" :: in liew of calling them system
level tests, integration tests, and unit tests

BDD does not aim to remove external documentation, but it does aim to
make the specification process programmatically consistent with
natural language.

Instead of "Unit Testing" you have "Behavior Specification".
Contrasting `ASSERT_EQUAL(_expected, _value)' with
`value(_value).should.equal(_expected)'. It's really just that simple.
