= Assertive Expressive

* http://proutils.rubyforge.org/ae/


== DESCRIPTION

Assertive Expressive (AE) is an assertions framework
intended for reuse by any TDD, BDD or similar system.


== FEATURES/ISSUES

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


== RELEASE NOTES

Please see HISTORY file.


== SYNOPSIS

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).

  assert(true)

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

  assert{true}

But the real power the AE's +assert+ method lies in it's use
without argument or block. In that case it returns an instance of
+Assertor+. An +Assertor+ is an <i>Assertions Functor</i>, or 
<i>Higher-Order Function</i>. It is a function that operates on
another function. With it, we can make assertions like so:

  x.assert == y

  a.assert.include? e

  StandardError.assert.raised? do
    ...
  end

And so forth. Any method can be used in conjunction with +assert+
to make an assertion. Eg.

  class String
    def daffy?
      /daffy/i =~ self
    end
  end

  "Daffy Duck".assert.daffy?

Please have a look at the QEDocs and RDocs to learn more.
