= Ruby Q.E.D.

== Introduction

Q.E.D. stands for Quality Enhanced Demos. QED is an easy to use quality
assurance and documentation system for Ruby Developers. QED sits between
lower-level testing tools like Test Unit and grand requirements
specifications tools like Cucumber. It is designed to address
API-Driven Devleopment, which is especailly useful when designing
reusble libraries.

== Features

  • Demos can be RDoc, Markdown or any other conforming text format.
  • Uses excellent Assertive Expressive library for assertion system.
  • Helpers are easily loaded relative to running document.
  • Table macro allows large sets of data to be run by the same code.
  • Documentation tool provides nice output with jQuery-based TOC.

== Synopsis

=== Assertion Syntax

QED uses AE (Assertive Expressions) libary to provide an elegant means
of express behaviors. To give a quck overview, you can use code such as:

4.assert == 5

In this example, because 4 != 5, this expression will raise an Assertion
exception. QED’s Runner class is thus just a means of running and
capturing code block containing these assertions.

You can learn more about AE at http://proutils.rubyforge/ae.

=== Document Structure

QED documents are simply text files --thus a practice of literal
programming. For example:

= Example

Shows that the number 5 does not equal 4.

    5.assert! == 4

But in fact equals 5.

    5.assert == 5

As you can see, we used RDoc for this document. Almost any text format
can be used. The only neccesary distinction is that desciption text be
align to the left margin and all code be indented. However QED
recognizes RDoc and Markdown style headers, so any format that supports
this style (which covers many markup formats in use today) will work a
bit better. While strictly speaking QED does not need to recognize
headers, it does improve console output.

Give this design some thought. It should become clear that this approach
is especially fruitful in that it allows documentation and
specification to seemlessly merge into a unified demonstration.

=== Running Demonstrations

If we were to run the above document through QED in verbatim mode the
output would be identical (assuming we did not make a typo and the
assertions passed). If there were errors or failures, we would see
information detaling each.

To run a document through QED, simply use the +qed+ command.

$ qed -v demo/01_example.rdoc

The -v option specifies verbatim mode, which outputs the entire

Notice we placed the QED document in the demo directory, this is the
concial place that has been designated for them, though you can put them
elsewhre in your project if you prefer. Also notice the 01_ in front of
the name. While this is not necessary, it helps order the documents
properly with generating QED documentation (QEDocs).

To generate documentation from QED documents, use the +qedoc+ command.

$ qed --output doc/qedoc --title “Example” demo/*.rdoc

When documenting QED recognizes the format by the file extension and
treats it accordingly. An extension of .qed is treated the same
as .rdoc.

Use the –help options on each command to get more inforamtion
on the use of these commands.

== Requirements

QED depends on the following external libraries:

  • AE - Assertions Framework
  • ANSI - ANSI Color Codes
  • Facets - Core Extensions

These will be automatically installed when installing QED via RubyGems,
if they are not already installed.

Should read
