AE v1.0.0 released

= A.E. – Assertive Expressive


Assertions Expressive (A.E.) is an assertions framework intended for
reuse by any TDD, BDD or similar system.


  • Clear, simple and concise syntax.
  • Uses higher-order functions and fluid notation.
  • Reusable core extensions ease assertion construction.
  • Core extensions are stable and standardized via Ruby F.s.
  • Facets is an optional dependency; extensions are built-in.
  • Easily extensible allowing for alternate notations.
  • Eats it’s own dog food.


=== 1.0.0 / 2009-09-03

This is the initial release of AE.


  • 1 Major Enhancment

    • Happy Birthday!


AE defines the method +assert+. It’s is compatible with the method as
defined by Test::Unit and minitest, which verifies truth of a single
argument (and can accept an optional failure message).


In addition AE’s +assert+ method has been extended to accept a block,
the result of which is likewise verified.


But these are simply legacy compatibility modes. The true power the AE’s
+assert+ method, lies in it’s use without argument or block. In this
case, it returns an +Assertor+ instance. An +Assertor+ is an Assertion
Functor, or Higher-Order Function, which is a function that operates on
another function. With it we can make assertions like:

x.assert == y

a.assert.include? e

StandardError.assert.raised? do


And so forth. AE’s abilities in this areas are quite extensive. You are
encouraged to read the QEDocs to learn more.
